How to Improve Bike Trails and Paths with Solar Lighting

solar lights for pathways

In the mid-1980s, an interesting movement happened across the nation where activists, historians, park groups, and similar people banded together to found an organization dedicated towards repurposing old rail corridors into public paths for everyone’s enjoyment: the Rails to Trails Conservancy was born out of this desire to connect people, develop public areas, and increase health. Today, the Conservancy is highly active all over the US and headquartered in Washington. It’s movements like these that Greenshine loves to promote because of their efforts in developing bike and walking paths, but it’s important to know that a trail itself isn’t enough–these trails wouldn’t be complete without adequate lighting fixtures to stay on when the sun drips below the horizon. Here are some ways that solar lighting for paths is excellent to increase safety for those commuting on foot or bicycle.

In Need of Solar Light from Above

Theft-Resistant Light Design

You might think that any kind of light will do just fine for a bike or walking path, but that couldn’t be further from the truth; the LA River Bike Path used to use grid-connected HID light fixtures for their path lighting until park officials noticed that vandals were stealing the copper in them and rendering the lights useless. The City of LA quickly switched to solar and saw a significant decline in vandalism since solar LED lights are very theft-resistant. There’s no doubt that vandalism happens on desolate pathways, especially when there’s something as valuable as copper to be stripped away from a light (copper theft is an actual epidemic in the US). That’s specifically why solar lighting for bike paths and walkways is ideal–the wiring is hidden inside of the pole, and the batteries that store the solar energy can be placed high atop the pole out of reach of vandals and thieves. Plus, Greenshine path lights are built with hot-dipped, galvanized, powder-coated steel poles. If anyone wants to try and vandalize the poles, well…let’s just say the pole will win. They’re the best in store for solar bike trail lighting.

Darkness = Danger

Without adequate lighting, a path’s topography isn’t easily discernible, nor are potential obstacles in the way. For bikers, this can spell accidents, collisions, and injury quickly. According to Lake County’s (Florida) former bicycle coordinator, Bruce Mackey, more than 60 percent of fatal bike accidents occur after 6 PM when there isn’t proper lighting in the area of concern. It’s feasible to close park and trail hours before 6 PM, but that doesn’t mean every guest or commuter will be off of the trail around that time. Using solar bike trail lighting with extended park hours is the best practice.

Bike Paths and Trails–Far too Distant for Power

Get Power without the Cable

We’re sure a large percentage of trails and paths in the US don’t have adequate lighting, and for good reason: it just isn’t practical to connect a path light to the power grid, especially if the trail is several miles long and distant from any kind of power source. The average cost to dig 100 feet of trench to wire lights together is nearly a thousand dollars (on the cheap end). One mile is 5,280 feet. If you’re planning on lighting even a single mile of pathway, trenching can potentially cost you 60 thousand dollars. That’s just a single mile for the pathway and specifically why we vouch for solar path lights–you can save the project budget 60 thousand per mile by using solar path lights. That doesn’t even account for the distance from the first light to the nearest available power source. It just isn’t practical nor budget-worthy, especially if the path in question is far away. One of our recent projects detailed how our solar lights illuminate a floating dock area–the project was far from any power grid connectivity (several miles). Plus, wired lights typically all go out if one of the lights has a connectivity problem.

Effect on Wildlife and Surrounding Areas

Solar is More Minimal Than You Might Think

Environmentally sensitive areas are definitely a concern when it comes to new lighting project; it may be the case that a particular area needs light only at certain times of night–perhaps specifically just for the time that a public park is open so that wildlife at night isn’t disturbed with bright LED lights. One of the greatest features for solar bike trail lighting is that these particular lights can be controlled any way desired. If they need to be “full brightness” between 5 PM and 10 PM and then shut off after park closure, the light controllers can be adjusted to that specification.

Grounds Conservation

No Trenching, 100% Grounds Conservation

We’ve seen plenty of examples where new lighting projects tore up park grounds and destroyed beautification efforts just to install wires. The last thing as a lighting company we would want to do is bring harm to any environment, which is specifically why we’re in the business of solar lighting for paths and parks. Each solar light is self-contained, great for the environment (no usage of fossil fuels), and has little effect on surrounding areas. Parks won’t need to have any sensitive areas torn up for wiring purposes, and the LED fixtures contain zero hazardous materials. Some lighting fixtures contain mercury, which needs proper disposal and can potentially damage the environment. Our LED fixtures are built with Cree LEDs which are 80% more efficient than traditional fluorescent or incandescent lighting technologies, so beyond the fact that we use an entirely renewable source of energy to power our lights, the use of power is highly economical.

Pulling power to a path in the middle of the desert? Not practical. Solar is more practical.

As a leader in the solar LED light market, the lights we manufacture are prime for use as solar bike path lights. We’ve got 30 years of combined experience under one roof, and we love to put our heads together to develop the safest, most economical lighting solution for your path, park, or bike trail. Let us know what we can develop for you with our solar solutions–you’ll find Greenshine is quite delightful!

 

airport perimeter lighting

Increasing Airport Security with Solar Lights

airport perimeter lightingA few years ago, a Colorado news outlet reported that several cars were vandalized inside of a parking lot at Denver International Airport. Two of the vandalized cars were actually stolen. What people initially thought was a safe area to store vehicles (they were rentals owned by a family) turned out to be unsafe for various reasons. Whatever the reason behind the unfortunate chain of events, sometimes crime can’t be avoided–it’s Murphy’s Law. However, that doesn’t mean crime can’t be minimized through proper safety methods and the right kind of lighting equipment. Along with regular patrol and surveillance, proper lighting in a parking lot is a necessity for deterring theft and vandalism. However, it’s not just any kind of lighting that suffices for crime and theft deterrence. Solar lights for airports that use LED fixtures are fantastic for keeping commuters and their belongings safe. Here’s some reasons why these particular lights are superior for parking lots and comparisons between competing light technologies.

Comparing Other Lights–HPS and Metal Halide

Color Reproduction

LED lights are known for proper color reproduction because they have a high Color Rendering Index (CRI) in comparison with other technologies. High-Pressure Sodium lamps typically fall under a CRI of 25, which is a very poor rating (LEDs are 80 on average). Because of their typical yellowish light, identifying color under these kinds of lights is difficult at best. Reds often tend to show up darker than usual (almost black). In the event of a crime, witnesses may not be able to properly identify an individual or what they’re wearing under light fixtures with poor CRI ratings. Plus, there are financial incentives to installing high-CRI lights (check out California’s Title 24 for more information). High-pressure sodium lights aren’t up to snuff when compared to LED lighting technology and how they perform for security reasons.

Metal halide lamps have some of the highest CRI ratings on the market, but at a significant disadvantage: the lamps typically take time to warm up in order to display their highest brightness (around 15 minutes), and their end-of-life behavior includes exploding–we’re sure nobody desires a lamp exploring above their head when they’re walking to their car at night. Plus, a metal halide lamp total operating time is around 15,000 hours–compare that to 100,000 hours of runtime for LED lights, and there’s a clear winner of technology. Metal halide isn’t prime for increasing safety in airport parking lots, and the level of maintenance is far too high and constant to maintain high levels of security. Imagine replacing metal halide bulbs for every airport security light in a parking lot every 18 months–not very practical.

Energy & Efficiency

Metal halide lights have a system efficiency of less than 30 lumens per watt because they’re omnidirectional, so light often times needs to be bounced towards the “focus” areas. Similarly, HPS lights are omnidirectional as well, wasting light because not all of it is targeted on the specific subject in question (in this case, parking lots). In comparison, LED fixtures are not omnidirectional, so their efficiency rating is better suited for airport perimeter lighting since the light is more focused. An LED light fixture focuses light in a 180-degree range, wasting less light and using less energy for superior brightness.

The Significance of Airport Solar Lights

What to Do About Connectivity

Another reason why solar lights are a much stronger option for airport perimeter lighting is because each light is standalone and doesn’t require connectivity to a main power grid. We recently had a full project where we replaced an archaic lighting system at Santa Monica Airport with airport security lights. Because none of the lights needed power grid connectivity, we were able to install them on the original light pedestals, saving the customer several thousands of dollars and weeks of time since they didn’t need to dig into the concrete for wiring the new lights. It’s examples like these that demonstrate why solar lights for airports are a superior choice over traditional. Plus, in any event that the main power grid fails, the lights will remain on. That’s just another feature to enhance safety for commuters–ensuring that, if all else fails, people won’t be left in darkness in the middle of an airport parking lot. Without proper lighting, the probability of personal injury and/or car accidents rises–avoid liability by ensuring people have the best airport security lights.

The Kind of Standards with LED Lights You Need

In order to maximize the light coverage per solar light pole, the best kind of light fixtures have strong light distribution patterns, or the projected pattern of light a fixture will disperse onto a surface. It’s important to note, however, that the best lighting practice for an area with security in mind is outlined in a guide published by the Illuminating Engineering Society of North America (IES) called the IES G-1-16. We won’t bore you with the details of what’s in the guide, but just rest assured that we follow the standards outlined in the IES manual–so our lights are not only just highly advanced airport security lights, but they’re configured specifically with security in mind. The light fixtures used for proper airport security are Type III fixtures so the light “throw” is a little larger and the lights can line the perimeter of the lot. We accept no less than the standard for security lighting.

In conclusion, the solar lights for airports that we manufacture are the best available on the market–with a high color reproduction index, low maintenance, long-lasting light fixtures, bill-less upkeep, self-sufficiency, and low installation costs (avoiding trenching and wiring), rest assured that your lighting setup from Greenshine New Energy will bring the best in security for your airport.

What are the Processes Behind Manufacturing a Solar Light?

outdoor solar lighting

Solar lighting is a bit of a modern marvel. Sure, we don’t often think about the manufacturing process of a solar light, or how a light is installed, or what fuels the light fixture to begin with. Those topics often take less priority when we’re trying to meet up with friends at night to catch the latest blockbuster movie or television show. But if you think about it, there’s a little bit of magic that happens inside of the components of a solar powered outdoor light. What we don’t realize is that the mundane is actually quite fantastic, and it’s hidden in the inner workings of the solar light as a whole. Here’s how the most important components of a solar light come together to reproduce the light given to us from the Earth’s largest bulb in the sky.

Solar Panel Manufacturing

The manufacturing process with solar lighting (the method that Greenshine uses) starts with silicon. A vast majority of photovoltaic materials are manufactured from silicon because it’s an incredibly abundant resource, making up about 25% of the Earth’s crust by weight. A silicon “seed” is dipped into a large vat of melted silicon and slowly rotated to draw out the purest silicon substance, which eventually hardens into an ingot. From this long cylinder of hardened, pure silicon, extremely thin slices are cut from the ingot and then prepped to have solar cells installed on them. This particular process is extremely slow and somewhat wasteful of silicon since the ingot is often trimmed down–but it produces the most efficient panels on the market.

Why are ingots trimmed?

Ingots are trimmed down in such a way to reduce as much silicon waste as possible, but also to shape the wafers so they fit properly onto a solar array small enough to be supported by a solar light pole. Thankfully, the wasted silicon can be re-used into other panels. Typically the excess is added back into the solar cell manufacturing process for poly-crystalline solar cells–a less-efficient solar technology, one that isn’t used for our solar lights. Greenshine utilizes only the most efficient materials on the market for solar powered outdoor lighting today. Does it take longer to produce mono-crystalline wafers? Yes. Does it produce more silicon waste? Yes, but that silicon is used in other solar panel products. Is it time consuming, expensive, and tedious? Yes, but we wouldn’t have it any other way. That’s what sets Greenshine apart from competition.

Working with LED Lights

LED light fixtures aren’t “one kind fits all.” When it comes to solar powered outdoor lighting, we focus on a lighting brand that delivers in three aspects: light quality, longevity, and energy efficiency. Cree LED lights hit those three aspects with flying colors, so to speak. Here’s the breakdown for each aspect and why these lights are perfect for pairing with a solar panel.

The Quality of Light

An average color temperature per light fixture we target is 4000K, commonly referred to as neutral white. It’s important to have accurate color reproduction, especially in public. The ability of a public light to accurately reflect an object’s true color is referred to as color rendition, and other light technologies don’t really score well when discussing that topic. LED produces the best color rendition for subjects illuminated under the fixture. Need convincing?

For comparison, the image listed here is of two vehicles sitting under a high-pressure sodium (HPS) light. Believe it or not, the vehicle on the left is red, even though they both appear to be black. That’s what bad color rendition results in; colors that aren’t reproduced accurately. And, honestly, ugly lighting. When searching for your car in a sea of potentially hundreds of others (we’ve forgotten where we parked too, sometimes), it’s nice to perceive the color of your car as it’s meant to be.

Believe it or not, the car on the left is red.

Longevity

LED light fixtures are designed specifically to last. Since LED lights operate with what’s known as solid state lighting, a lot less heat generates from the light source (as opposed to sodium-vapor methods). If you need a demonstration, check out Cree’s video on how a chocolate bunny melts under an incandescent light. Of course we’re dealing with much larger fixtures when it comes to outdoor lighting, but it’s nice to know that LEDs are built for longevity because they produce significantly less heat than other lighting technologies. LEDs can potentially last over 100,000 hours. That’s over 11 years. Some cars don’t last that long.

Energy Efficiency

Signed into law in 2007, the Energy Independence and Security Act established an efficiency standard for lighting, stating that bulbs and fixtures on the market needed to utilize 25% less energy. Thankfully, LED lights at this time were well on their way to being affordable and viable for use in public areas under this standard. LED lights today are approximately 80% more efficient than most other lighting technologies! Since they’re much more efficient, less energy is required to produce the same amount of light, costing less. It’s a literal win with LEDs and energy efficiency, which is why we pair them with our solar powered outdoor lights.

Bottom line, we’ve done the research to determine the best LED lights on the market for use in our solar lights. The trifecta of success–efficient, color accurate, and long-lasting–is perfect for use in solar lighting fixtures wherever lighting is needed in parking lots, parks, streets, pathways, or other places.

Greenshine New Energy has been in the solar lighting business since 2007, and every year we’ve seen improvements to light efficiency, solar technology, and significant price drops for both–panel installation prices have dropped over 50% in the past decade! Our crack team of engineers can design a solar outdoor lighting system to fit your lighting needs and budget. We’ve saved companies hundreds of thousands of dollars via lighting solutions that save on energy usage, trenching, and wiring.

What in the World is a Light Fixture (and What Are the Best Ones for Solar Lights)?

exterior solar light fixtures

Here at Greenshine, we toss around lighting terminology all day–lumens, wattage, temperature coefficients, mono- and poly-crystalline–the jargon can get particularly heavy. We thought we’d educate the masses through defining what a fixture is, how fixture technology has advanced in the past few years, and how that matters when it comes to solar LED lighting. Check out this 5-minute read on the greenest lighting technology available.

Light Fixture Fixin’s

A fixture is defined as an electrical device that contains an electric lamp that provides illumination. It’s definitely a broad term, and yes, you can even find them in your home and outdoors on light poles. They’re considered the “main deal” when it comes to solar LED lights.  Some are pretty basic, some can get very ornate, and others are purely functional without any decorative flare. Not one fixture fits all situations though, and so we’ve dived into some of the best solar outdoor light fixtures for streets, public areas, parks, and other purposes. Just so you’re aware, this isn’t an exhaustive list of fixtures, only the best for exterior solar lights found at Greenshine.

Type II

The first fixture that Greenshine offers, Type II fixtures are slightly wider than their predecessors (aptly named Type I) so that the spread of LED light is a little broader. Whereas Type I has a very narrow band, Type II is better for sidewalks, park paths, and wider areas that see a lot of foot traffic. It’s a highly common light fixture and one of the most popular for pedestrian paths located by the roadside or in public parks. Check out an example of how our Lita line improved a pathway located in a park for the enjoyment of nearby residents.

Type III

Type III lighting systems are wider solar outdoor light fixtures meant for parking lots, wider areas of foot traffic, street lighting, and other areas that require broader lighting beyond pathways. This fixture works ideally with a lateral width of 40 degrees. These are currently the most popular for Greenshine and used on a wide variety of solar LED light installations across the US.

Type V

Type V utilizes a circular layout so that every light gets maximum exposure without specific direction. It’s suggested that these kind of solar outdoor light fixtures are used in sprawling parking lots, high-traffic streets, and anywhere where there needs to be wide, untargeted coverage. Typically these are found in larger parking lots, construction yards, and places where coverage is key.

All of these LED fixture Types work within Greenshine’s pole-mounted lighting solutions including the Supera, Brighta, Lita, and other solar outdoor light fixtures we manufacture.

How Light Fixtures Have Improved

Efficiency and Price

With every product iteration, we’ve improved efficiency and price per watt. You see, the light fixture isn’t just about where the light is held. The light fixture is highly engineered by experts to maximize output, minimize potential harm to the fixture (heat can significantly reduce efficiency), and increase functionality. The newest light fixtures that Greenshine offers are 15% more efficient per watt than previous models, resulting in a brighter area of light that uses less energy drawn by the solar panel and stored in the battery. LED lights have seen a price drop of 150$ per kilolumen in the span of eight years. In 2030, who knows how efficient and inexpensive LEDs will be? Plus, since we’re talking solar outdoor light fixtures, they don’t need centralized power connectivity so you can save on trenching and wiring, which are usually very expensive tasks–some lights require approximately $4,000 per light just for connectivity. That’s no pocket change.

Heat

Vast improvements in heat dispersion have boosted LED longevity significantly. The junction temperature is the primary culprit behind the eventual deterioration of an LED light, which is raised by what’s called the ambient temperature and the drive current. Junction temperature is often managed on the newest light fixtures by high-quality heat sinks or cooling fans to dissipate heat, prolonging the life of the light (an average LED light will last about 11 years with 12 hours of use a day). Heat happens to be the #1 LED killer, but modern enhancements have drawn away high temperatures so that LEDs last even longer than they used to.

Smart Controls

One of the newer functionalities for solar outdoor light fixtures is that smart controls can be added to the mix. Lighting isn’t just a matter of being “on,” it’s a matter of giving complete control of the lights to improve longevity and functionality. A solar light can be configured to turn on at the start of dusk and slowly ramp up brightness to “full” brightness once the sun’s light isn’t adequate for an area. Each light can be configured to be “on” at a certain percentage during a specific time of day so that the target area gets as much light as it needs–reducing overall fixture and battery usage, thus increasing longevity. We’re sure solar outdoor light fixtures left on at full brightness all day won’t last as long as lights that are turned on only when needed. Plus, each light can be connected to motion-control cameras to blink on as soon as motion is detected. Smart controls and added functionality like this bring security where it’s needed most–we’ve seen vast improvements in safety for rural areas since we’ve installed some of our systems in remote areas where grid power isn’t available.

We hope this brief introduction to exterior solar light fixtures is great for anyone curious about how they operate and how they’ve improved over time. Perhaps by 2030 we’ll see even higher efficiency ratings and lower prices for LEDs. For now, contact us to learn more about what we can do for your lighting needs through the power of solar LED lights.

The Cost of High Temperatures on Solar Panel Lighting Systems (and How to Combat Them)

best solar lighting system

There’s always a concern about heat mixed with electronics–leave your smartphone in a hot car, and it may actually turn into an expensive brick once the internal components fry from prolonged exposure. It’s no secret that heat will cause electronics to malfunction, although the case is a little different with a solar light. We’re sure someone in the past has held concerns about how a solar light performs when the panels (and the important components of the light) sit in the sun and bake. The bad news is that there is an unwanted affect of high heat on solar panels, the lights, and some of the components for the system. The good news is that the effect of baking in the sun is not as terrible as you might think, and there are options to circumnavigate those problems. The heat won’t be cooking the panels or lights to a “dumb brick” state, but here are some facts on what really happens when a solar street lighting system faces some scorching days and what you can do to protect your investment against them.

How Heat Affects Different Solar Panels

When discussing solar panel efficiency and how that relates to temperature, it’s important to be concerned about what’s called the temperature coefficient. This concept is expressed in a Celsius degree. If a particular panel has a temperature coefficient of -0.25% per degree of Celsius, every degree that it rises above the standard testing threshold of 25 degrees suggests that it loses a quarter of a percentage of efficiency. The math is pretty simple. With that particular temperature coefficient, let’s say a solar panel heats up to 38 degrees Celsius, which is 18 degrees beyond the standard testing threshold. That means in that particular heat, the solar panel has lost 4.5% of its efficiency. It’s not any sustainability-threatening factor, but heat definitely robs the solar panel of some power.

With that in mind, it’s important to find the best solar lighting system with the lowest temperature coefficient. That’s going to ensure that when your solar panels see some scorchers they still produce significant power. After all, a solar panel is meant to be in the sun. The lowest tested temperature coefficient will reduce the impact of high heat on your panels. An average temperature coefficient is -0.5%. Any panels rated below that will definitely be worth the initial investment–get as much power available from the sun as possible. Further advancements in solar technology will likely see temperature coefficients drop into the 20s or even teens. That’s an exciting trend we hope to see in the near future.

How Heat Affects the Electronics of an LED Light

LED lights absolutely love cooler weather. It’s a fact that they are more energy-efficient in winter and cold environments, but LEDs aren’t as impactful in high heat. The quality of light and lifespan of an LED light can be affected from heat exposure, but heat dissipation depends on a few factors:

  • the heat sink for the LED light
  • how the light is mounted into the fixture
  • if the lights are in a housing or not
  • other smaller factors that dissipate the heat

It’s important to check with the manufacturer in order to get proper ratings for heat exposure.  Cree LED lights are rated pretty highly to withstand the hottest climates and operate best around 25 degrees Celsius, although they still operate fine after exposure in prolonged temperatures above that.

As far as the heat produced by a solar LED light, the fixtures themselves don’t actually produce much heat at all. Heat is produces within the diode itself, and a properly designed fixture can dissipate that heat directly away from the lighting subject. The hottest surface of an LED is, on average, 50% cooler than other lights! They’re often cool to the touch. You could even place your palm against the light fixture and not worry about getting burned–seen as incandescent bulbs waste about 90% of their energy as heat, we don’t recommend touching them. Bottom line though, when you have a street lighting system built up entirely of LED fixtures, there isn’t much to be concerned about when it comes to high temperatures. The lights are pretty stable in any environments, hot or cold. That’s a sign of quality.

Heat on Batteries

Heat is a definite battery killer simply because prolonged exposure can lead to leaks, corrosion, a shortened lifespan, or a combination of all of these problems. When you have batteries exposed to constant sunlight within a solar street lighting system, the higher the temp of the batteries, the more power they produce–to their detriment! The battery lifespan will actually deteriorate when exposed to high heat. Recent research online shows that a rise in 8 degrees Celsius cuts the life of the battery in half. That’s significant for a temperature change, and so we can understand concerns about how a lighting system might function when it’s battery-powered. It’s important to find methods to regulate the temperature for the battery to maximize its lifespan.

How to Combat the Heat

At Greenshine New Energy, our solar street lighting systems are built to combat the heat. We utilize mono-crystalline solar panel technology with temperature coefficients that match the technology standard today of -0.5% in order for our panels to stay as efficient as possible. Our batteries are engineered to utilize approximately only 18 percent of their charge, so even in the highest temperatures you’ll see less degradation over time. Enjoy that 5 to 7 year timespan of battery life on the solar light with very little maintenance. Our lighting systems come with a myriad of options as well. If the batteries will get constant exposure to extreme heat, you can bury the battery in the ground for higher protection against the elements.

We’ve thought ahead of all possibilities when it comes to extreme temperatures, weather of all sorts, and degradation of our components. When you go with Greenshine, rest assured that you’re getting components that can take a lot of mother nature’s abusive weather patterns.  Our configurable systems are designed to get maximum results regardless of how much the sun bakes the area–that makes it the best solar lighting system available on the market for the money.

An Example of How Outdoor Solar Lights Benefit Schools

outdoor solar light fixtureOne of the greatest aspects about Greenshine’s outdoor solar lights is our versatility when it comes to where our lights operate. It’s probably the case that you’ve even come across one of our several thousands of installations in the United States. There are, however, more unique projects under our belt that really “shine,” so to speak, and we’re proud to talk about them here. Beyond the parking lots, pathways, streets, and park installations, Greenshine New Energy recently installed solar outdoor light fixtures at Rairok Elementary School in the Marshall Islands. It was one of the most successful projects the company had since a lot of the islands utilize diesel power generators–not the cheapest or cleanest options for power generation.

The Benefits of Solar Lighting on Marshall Islands

Not having any lighting near the playgrounds for Rairok Elementary was a clear problem for childrens’ safety, so Greenshine developed a system of solar outdoor light fixtures in order for safety measures to increase. The engineers at Greenshine designed a 9-light Brighta-40 system coupled with mono-crystalline solar panels to capture the sun all day long and keep that light going all night long. Coupled with Cree LED bulbs, this lighting system was incredibly efficient at taking the sun’s power and turning it back into usable light for everyone to enjoy. The entire system provided over 50,400 lumens with a much more accurate color reproduction than incandescent or high-pressure sodium lights, effectively lighting the area. In addition, the grounds were kept intact because the system didn’t need trenching or wiring. This saved the school significant sums of money.

The Best Lighting Solution for the Money

The outdoor solar light fixtures installed at Rairok Elementary solved the problems of the school by providing cheaper, cleaner energy pulled by energy-efficient solar panels and used by cost-efficient LED bulbs. It’s just simple things like lighting that can “brighten” even a student’s day while keeping bills low and budgets intact. We’re proud to offer the best lighting solutions for the money, not just for Rairok Elementary, but for many other clients as well. If you’d like to be next in line to save money and light up the night, contact us to learn more. The future of lighting is cheaper thanks to solar, and we’re happy to be a part of it.

3 Ways to Save Money on Public Lighting (It’s Easier Than You Think)

best solar street lighting

We’re in the business of solving problems. Just last week, we had someone call our office thanking us for our help with providing solar parking lot lights for their business. We’ve even been invited as guests to speak at business conferences in the past, marking us as pathmakers in our own field. We don’t mean to boast (well, maybe a little), but the facts are pretty clear; we’re in business for business, and if you’re looking to save a dime on every dollar, you’re in luck. We at Greenshine New Energy offer the best solar street lighting for your illumination needs. Here are the reasons why it’s the best, and we won’t be shy about it.

Long-Term Energy-Saving Lighting Solutions

It’s a bit of a mouthful, but since 2007 we’ve been developing and perfecting long-term energy-saving lighting solutions. One of the secrets is in the usage of solar power. Instead of connecting to a main power grid, we pull power from the sun. Did you know that every hour, the sun bestows upon the Earth over 400 quintillion joules? That’s more than what the entire world population uses in a year. The energy is there, and so are the savings. Utilizing the mono-crystalline solar cells we provide will make sure you get the most efficient solution on the market, turning star-given light into LED light.

Do you enjoy not having to pay energy bills? We sure don’t, and when you use the sun for your energy the savings start to surmount. Please your guests, commuters, boss, and wallet all at once. If you find you have an abundance of solar energy, you can even sell it to the state and earn money. Imagine that–a solar street lighting system using LED lights that pays you money for basically doing nothing. That’s kind of why we call it the best solar street lighting–you can sell stored energy back. But there are other avenues other than just saving and making money on energy, and they’re often times a little hidden out of plain sight.

Trenching Costs Skyrocket the Price

One of the biggest wallet drains for installing any kind of lighting is often times not even the light itself. Lighting needs power, naturally, but in order to power the light without solar energy, you’ll need to connect the light to the main power grid. That isn’t just a plug-and-play matter. You’ll need to dig, and digging gets expensive quick. HomeAdvisor quotes trenching costs are no thrifty matter. Then there’s the cost of wiring and connecting each light to each other. Plus, there’s a fundamental weakness with connecting these lights together, and it’s much akin with what happens to Christmas lights–if one goes out, they can potentially all go out!

Solar lights are powered independently, so each light doesn’t depend on another to deliver power. In the event of a power outage, your solar lights will remain on. Modern problems require modern solutions, and when the power drops, your problem is already solved.

These Lights Won’t Burn Out Anytime Soon

The news about our best solar street lighting is that these ultra-bright behemoths actually use some of the most energy-efficient bulbs. LED lights use directional lighting, so the light doesn’t need to be bounced in any direction. Plus, each LED bulb gives off very little heat ensuring that energy doesn’t get wasted by transferring to heat. That’s more money in your pocket. Are you aware of the longevity of these LED lights?

The light fixtures, panels, and poles are rated to last two decades. That’s right, you can send a kid off to college before you’ll see these start to fail (best case scenario). And we’re sure in those 20 years, mother nature won’t be kind to these lights. They’re rated to withstand high temperatures (naturally), low climates, high winds, and unruly children. We’ve made these things to last through anything short of armageddon. So rest assured that when the light goes up, there’s little chance whatsoever of it coming down. That’s the quality we adhere to.

So there’s our three ways of saving money when considering solar parking lot lights : save on energy costs, save on trenching bills, and save for longevity. That trifecta alone is key to seeing your receipt shrink and energy bills drop to zero. It’s one of the reasons we do so successfully in the solar lighting business–most just aren’t aware of the benefits of solar, so we’re here to educate, save, and make those smiles pop. Contact us if you’d like to learn more–if you enjoy saving money, that is. We’ll bet that’s the case.

Understanding the Types of Solar Cells

solar led lights and solar street light informationIn the past 10 years, we’ve seen green technology make significant advances in efficiency and cost-effectiveness. There’s no longer a looming question of whether or not solar technology is a viable path of energy use; now solar LED lights are a mainstay in cities, public streets, parks, and other public places because of the advancements in technology and lower prices. But there’s more to solar light than just the price. Solar technology has grown to include several different developments, each with their own strengths and weaknesses. However, one particular kind of panel may not be the best for your lighting project. Here, we dive into the differences of solar energy panels and reveal the technology that’s worth the investment. Stick around, there’s more fun in solar than you might think.

Solar LED Lights are Manufactured with the Best in Mind

Perhaps you’re a computer person and you want the best cluck for the buck. You’re not going to settle for something that will start to slow down within 6 months, you want longevity. So you try to find the best deal. You’ll probably pay more up front for the computer you need, but the initial investment is worth it because your computer won’t show signs of aging quickly. That’s kind of the same with solar LED lights. If you’re willing to spend a little more, your energy yield becomes significantly larger. There are many solar cells that have been developed since the dawn of photovoltaics, and we’ll take a brief look at them to see what they’re worth. Prepare to be educated with the current types of solar cells combined with solar street light information.

Poly-Crystalline Solar Cells

Although a newer technology and slightly more attractive to the eye, poly-crystalline solar cells aren’t ideal for solar LED lights. This is because the crystals are lower quality slices of silicon since they are less efficient between the crystal “seams.” You’ll likely see a 20% efficiency with poly panels, so you won’t really get your money’s worth even though the technology is cheaper. Plus, you’ll need larger panels for any sort of solar street light installation. Larger panels might not bode well on top of a solar light pole. As before, if you want the highest cost-to-performance ratio, steer clear of poly panels. They’re pretty to look at, but pretty doesn’t always mean powerful.

Thin-Film Solar Cells

Thin film cells are produced primarily for the residential market because of their convenient thin design. They’re terribly inefficient, less than poly-crystalline panels. You’ll need much larger surface area for these kinds of panels in order to operate solar LED lights. With a considerably larger panel, this kind of technology just wouldn’t work well for any kind of public lighting. A larger panel on top of a solar light pole suggests lower stability, and we don’t think it’s practical to have an unstable pole around people–you can guess why. Plus, these thin film solar cells are manufactured from a substance called cadmium, a highly toxic substance that many are wary about using for photovoltaics. We try to be better for the environment, not worse.

Mono-Crystalline Solar Cells

These are known for being the most efficient on the market. They’re expensive and a little more wasteful than the other types of solar cells, but these are perfect for lighting solar LED lights because of their size and efficiency. The relatively smaller panel sizes are perfect to have on top of a solar light pole without sacrificing stability. Plus, some mono panels are rated at efficiencies of 30%, so rest assured that this kind of technology gets the most energy from the sun for your dollar. Coupled with bright, low-energy consumption LED lights, this kind of solar technology is best for any sort of public lighting project.

Why This Technology Matters to You

So how does that feed into solar street light information? We want to educate project managers and city officials on what works best for public lighting. At Greenshine, mono-crystalline solar cell technology is what we adhere to in order to deliver the most cost-effective solar LED lights today. We get the best in order to deliver the best, and we wouldn’t have it any other way. Solar is paving the way to a cleaner future. We’re happy to be in business for business, delivering the best bang for the buck while keeping things green, both for the environment and your wallet. Contact us to learn more.

What the Buy American Act Means (for Solar Lighting)

solar street light suppliers USA and solar light manufacturers

We’re sure you are focused on quality when it comes to purchasing anything. You’re like us–when you get a hankering for something, you do your research by going on Amazon, look at product reviews, and educate yourself on what the best bang for your buck might be. That’s human nature. When the dollar goes down, we want to ensure it carries the most weight. It’s also natural to be curious about where the product comes from. That’s why solar street light suppliers in the US focus on the Buy American Act. One of its stipulations states that the end-product must be manufactured in the United States. It’s something that we’re proud to stamp in our catalog so that all customers know they’re buying stateside. It’s part of the quality assurance we give to every customer so they know they’re not purchasing solar street lights that aren’t to a quality standard. What do we feature with our standard? Let’s take a brief look into the details. Time for education!

Our Solar Street Light Quality Standard

Fighting Against Heat

One of the claims to fame that we carry with us is that our solar street lights are resilient to the extremes of mother nature. Naturally, our lights are featured in hot, arid climates where the sun shines often so we expect temperatures to be brutal on our installations. Yes, heat has a negative effect on solar panel power output. The higher the temperature on a solar panel, the higher the current will rise. However, the voltage for the panel has an inverse correlation. The higher the temperature, the lower the voltage! The sun sometimes can be its own culprit at providing power. So what’s one of the ways around this particular solar power problem?

Greenshine has committed to using monocrystalline solar power panels for every project. We’re one of a handful of solar light manufacturers in the United States that solely manufactures all of our solar street lights with mono panels. The secret to our success (and thus savings) is that monocrystalline solar panels are the most efficient at turning sunlight into power. Yes, they’re more expensive and time-consuming to produce. Would we have it any other way? No, because we want to make sure you get the most energy out of the sun as possible with your solar street lights. Using the most efficient solar power solution will garner results. Why compromise since you’re lighting a street?

Performing in the Cold

It’s noteworthy that solar panels actually function well in colder climates! However, the flip side to cold climates is that snow can block the sun from energizing the panel. We tend to combat that by tilting the panels at a happy medium of culling as much sunlight as possible while tilting it just right so snow typically falls off. If it sticks, chances are the snow will melt enough within a day so you won’t even need to do anything. However, if the snow sticks for an excessive time, that’s when you’ll need to call in a professional to knock the snow loose. These high-quality solar panels sometimes need a little bit of care in order to be maximally efficient. We want to make sure your investment gets you the biggest return on energy so those savings skyrocket. When in doubt, call someone to clean up the snow.

Wind is No Match

We’re sure there are concerns with wind too. Fret not! Our solar street lights are rated to withstand gusts of up to 145 miles per hour, so even in category 3 hurricane level winds these massive installations will remain standing no problem. That’s just a part of the quality you receive when you buy American–ensuring that your new street light installation will remain on and up through thick and thin. A recent installation of ours in Guam was hit hard with a typhoon with sustained winds of 95 miles per hour. After the storm blew over, our lights remained up and on. That’s our testament to quality.

The Buy American label isn’t just something to brag about. It means our products are manufactured stateside, so you can ensure you won’t get a flimsy light or pole that will malfunction within a year. If you’re concerned about where our solar street lights come from, how they’re made, and their test of quality, we stand by each solar light system as an example of our commitment to quality. Purchase stateside, and we’ll guarantee your satisfaction with our product. We combine the most efficient solar panel technology with low-energy consumption LED lights on top of climate-resistant poles. Contact us so you can be a part of the newest technology for solar lighting, or take a look how solar can save your business or city money. You’ll find out why we’re one of the top solar street light suppliers in the USA. Thanks for reading.

The True Costs of Traditional Lighting vs Solar

solar street light installation cost

When scrutinizing the details of a project, especially the budgeting aspect of it, it’s important to consider all options available to you in order to justify the dollar. Lighting is no stranger to this; something as simple as illumination in the dark can be incredibly expensive. We know those roads well, and we’re here to see that receipt get a little shorter. Traditional lighting methods–often times using high-pressure sodium technology–can be tried and true, but we’re here to tell you about solar street light installation costs. The total bill, when compared to traditional street lighting costs, is actually significantly less than you might think. Here’s the breakdown:

Traditional Lighting Costs Are Deceptive

Initially, the costs for standard lights are attractive because they’re not paired with solar technology. But a closer look shows that you’re paying a lot more than just the lights–you have to pay for the trenching and energy bills as well. Over ten years, the prices add up. Solar beats out on the costs for street lighting by skipping out on trenching and, well, it’s fueled by the sun–so don’t worry about any energy bills. We’ve even saved a company several thousands of dollars up front on day one of installation. It’s a smart thing, that solar technology. And we’re proud to offer it without hefty bills for installation. Trenching alone can cost between 5 and 12 dollars per linear foot. Why not just skip the bill altogether?

Here at Greenshine New Energy, we’re proud to offer commercial lighting solutions that light the way towards savings and a brighter future. Be a part of the solar revolution by investing in the energy resource of tomorrow: the sun.
