Why Are Solar Lights for Pathways Superior to Alternative Lighting?

solar lights for pathways

Public lighting isn’t something that’s thought about very often–we doubt you’re raving about how there’s a new light system with a Type V light fixture at your favorite park. But something as mundane as a pathway light can actually be quite marvelous, especially if the light in question is an outdoor solar pathway light. These kinds of lights are highly technological, extremely cost-effective, and fantastic on the environment. If you’re in the market for a new project to illuminate a public path with lights, stick around–this 6-minute read will educate you on how to keep your wallet fat and your smile bright via the power of Earth’s closest star. Read up on the benefits of solar.

What is the Best Solar Panel Technology (For Lighting Needs)?

Here is a picture of commercial solar lighting that uses solar LED lights to power areas.You’re probably aware that Greenshine is a company that specializes in solar lighting. You’re also probably aware that solar lighting uses solar panels. If you’re not aware of these facts, welcome to our site! For the remaining crowd, or for those who we have piqued interest, we’ve developed a comprehensive guide of solar technology and pinpointed the ones that are best for parking lot lighting and similar applications. Stick around for this 6 minute read and you’ll learn the in-and-outs of solar panels. There may be technologies on here you haven’t heard of, so there may be more learning opportunities ahead. Prepare thy noggins, here’s a lesson in the exciting world of photovoltaics.

What is the Best Solar Panel Technology for Lighting?

There are many, many types of solar technologies, so it’s important to understand what’s out there, what’s new, what’s not, what’s hot. Here’s where we dive into several different technologies, some very high-tech, to understand what gets the best ding for your dollar. The jargon can get a little thick from here on out, so we’ve slimmed it down to understand the essentials when it comes to photovoltaics. The biggest factors come down to the materials they’re constructed with (and their environmental impact), cost, and efficiency.

Bifacial solar cells

There’s not much behind the name with bifacial solar cells–it’s a solar cell with two faces. Since solar cells have come down in price across the board with several different technologies, bifacial has seen more popularity in the past decade for companies. The energy yield for bifacial cells, however, nets about 10% more power than single-panel cells, and so the price investment doesn’t yield much of a return on power. Plus, there’s about a 5% market share in comparison to more commercially available technologies. A typical optimal solar panel angling is 45 degrees south, and so tilting a bifacial panel would deny the opposing side exposure to the sun. Basically, you pay for two panels but don’t get the efficiency. We might see higher application for bifacial solar panels in the future, but as for today’s applications it still isn’t the best solar panel technology for lighting.

Cadmium Telluride Solar Cell

what is the best solar panel for lightingA CdTe cell is an interesting technology that uses cadmium telluride as its semiconductor. It’s actually cheaper than crystalline silicon for solar panel development and carries the smallest carbon footprint in comparison to other technologies, but the drawback is that cadmium is a highly toxic chemical that isn’t as abundant as silicon. With a legitimately questionable impact on the environment, CdTe cells are best reserved for larger solar panel arrays (such as massive solar farms) instead of poles for city and business lighting.

Thin-Film Solar Cell

Labeled as a “second-generation” solar cell, thin film solar cells use different semiconductor materials (other than just silicon). As its name suggests, it’s much thinner than crystalline silicon cells, making it highly popular for rooftop installations because of its pliability and portability.  Its biggest drawback is that it isn’t very efficient in comparison to more common market technologies (about a third compared to standards) and the cost is typically 5 times higher. Current market trends show that a lot of materials suppliers for thin film have gone out of business, suggesting that thin film might be gone soon or too scarce to be marketable.

Polycrystalline Solar Cell

A “poly” cell is manufactured from what’s called the Siemens process in order to form silicon into a solar cell. Poly cells consist of small crystals (thus poly) that result in a metallic look. It’s a highly-used technology and one of the most commercially available types of solar cells. However, it’s a less-efficient semiconductor than other technologies. Polycrystalline is typically used in home applications and for people or companies that just want something cheap enough to use in their own projects. Skip it.

Perovskite Solar Cells

what is the best solar panel for lightingPerovskite cells are gaining steam in the solar cell arena, but the technology has really only begun to compete with more traditional solar cells. Instead of silicon, the solar cells are manufactured with perovskite, a mineral found abundantly in the Earth’s mantle. While the technology is rapidly gaining popularity in use for solar power applications, it hasn’t been often used for solar lighting because of price: gold is a common component in perovskite solar cell manufacturing (no explanation needed there). Plus, cheaper cells have a shorter lifespan in comparison to more commercially-available technologies. Perovskite cells decay rapidly in moisture as well, so even a light rain can damage the cell. This calls for stronger encapsulation, which drives price and weight up. Toxicity levels are a concern too since some cells use lead and a substance called Pbl, both highly toxic to the environment. Perovskite cell improvements will pave a path for PV in the future, but it doesn’t operate well for solar lighting in its current state.

Monocrystalline Solar Cell

Monocrystalline technology is a tried-and-true form of silicon-based solar cell manufacturing. The Czochralski process behind manufacturing the cell takes longer than the Siemens process and is more wasteful of silicon, but the efficiency rates are considerably higher than thin film and polycrystalline cells averaging about 25% efficiency. Since the Czochralski process has been highly researched and developed over the past decades, the result is a relatively cheap method of solar cells that can be housed in lightweight encapsulations–perfect for installing on top of solar light poles. That’s the best solar panel technology for solar lights.

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.

Is it Possible to Re-Use Existing Poles and Concrete Bases From Old Lights?

commercial solar light post

So you’re probably here because you already have a lighting system in place. Perhaps something happened and now your entire light infrastructure has gone out due to one small mishap in the wiring, or perhaps the whole shebang is kaput. The wallet is slim and so are your options, so you want to keep the existing poles without installing new ones. The good news is that yes, you can “retro-fit” solar powered pole lights onto existing poles. The bad news is not with every pole.

Solar Powered Pole Light Info

If You’re Not Using a Solar Lamp Post…

What matters most is in the construction of the light fixtures. Our solar light fixtures are behemoths that are normally built with poles that can withstand temperature changes and 140 MPH wind gusts–we’re not talking some flimsy foundation here. So if there’s a retro-fit operation to be done instead of using commercial solar light posts, it’s a viable job if the original pole is built like a brick house–wood or concrete poles from city installations fare well. Poles from older light installations aren’t as viable, and if the foundation isn’t solid, the pole won’t be either.

If there are still burning questions if you want to move to a full solar installation, feel free to contact us and ask about your current situation. We’re willing to work with you on whatever solar light installation you need, so if you have sturdy poles in place for a retro-fit installation, excellent! If your old lighting system looks like a strong gust of wind can knock it over, we can provide better options to see your project revived and completed. After all, if you’re going to invest in solar, it’s important to ensure it can withstand what mother nature may throw at it. We’re Greenshine New Energy, where poles aren’t monkey business to us.

LED Streetlights vs HPS Streetlights: What’s the Diff?

outdoor solar light

Prepare yourselves, we’re breaking down a big comparison in street lighting today! We’re discussing the comparisons between light-emitting diode (LED) and High-Pressure Sodium (HPS) lighting systems, and hopefully by the end of this lesson we can educate you and ensure your wallet stays happy. Here are some main differences between LED streetlights vs HPV streetlights. Hint: LEDs win this battle.

The Answer Lies in Lumens

A quick search reveals that a lumen is defined as “the SI unit of luminous flux, equal to the amount of light emitted per second in a unit solid angle of one steradian from a uniform source of one candela.” We don’t prefer to baffle our readers with jargon, so for our reasons lets just define a lumen as the standard of how light is measured when we discuss LED vs HPV. That term is primarily used in discussing efficiency behind lighting–how much light you get per energy invested. A standard “return on investment,” if you will, for light. The efficiency for LED lights ranges between about 40 and 120 lumens per watt. The lumens per watt rating is actually higher for HPV, but where these lights lose is that they’re omnidirectional, so you get a lot of light striking objects that aren’t intended to be lit. The benefits of outdoor led vs hps lumens per watt is greater because there’s less “loss” of light. LEDs have a light spread of 180 degrees, and so more light is actually directed towards the subject in question. Why bother buying a kind of light if half of what it emits goes the opposite direction of where you want it to go? LED wins this bout.

High-Pressure Sodium: Hot, Hot Heat

High-pressure sodium lights produce heat–not something you’d really want when your main concern is just illuminating something. The heat emitted from the light either wafts out into the great wild or is absorbed by the ballast. Turning that heat back into light is ideal–or by using a light that emits very little heat whatsoever. In this case, LED lights win again since hardly any heat comes from them.

LED Wins with Longevity Over HPS

We’ll admit that HPS lights have fantastic longevity, which is often times why they’re chosen to light parking lots and wide public areas. However, LED lights still win in this category–surprise–with a whopping 25 thousand hours of usage time vs a max of 24 thousand hours with HPS before failure. It’s marginal, but we’re sure when weighing options that a little more time is better than a little less. LED beats out HPS in this category regardless.

Maintenance, Money, Maximum Brightness, and More!

Here’s where LED really shines,  so to speak. LEDs require virtually no maintenance. The bulbs last so long they beat out all the competition in terms of longevity and so don’t need a replacement, unlike HPS. So less maintenance requires less money–you get the idea. Plus, LEDs have a more accurate color reproduction. We’re sure you’ve been under HPS lights before, and they cast an unsightly yellow color over everything! That’s not exactly the most pretty of colors. Plus, LEDs are known for being “immediately on” in the industry, while HPS lights take about 10 minutes to warm up to full brightness.

We’ve only listed a smidge of benefits LED lights have over HPS! The benefits are heavy in comparison, and even better when you combine LED lights with solar panels. If you’re considering a switch or are convinced here of the superiority of LED lights, feel free to contact us for further information. We’re invested in the future of lights.



Solar Panels for LED Lights

What Are the Benefits of Angling Solar Panels Properly?

Solar Panels for LED Lights

New solar panel light adopters may not be entirely up-to-date on how to properly angle new solar panels and why that matters. Of course, it’s ultimately a matter of drawing as much light from the sun as possible, even during overcast times, so we thought we’d introduce a few basics to those who have installed the latest in green energy technology. And for those who haven’t used solar lighting in their latest project, consider this an opportunity to reflect if solar panel outdoor lights are perfect for your needs. We’ll skip the super-tech details and jump straight to the specifics.

How to Properly Angle Solar Panel Outdoor Lights

What’s the Best Angle of Direction for Solar Panels for LED Lights?

We’ll admit that solar isn’t perfect. Sometimes the sun doesn’t come out, and so you’re left wondering how long your lights might last in dark winters or overcast times. Solar power stored in a battery won’t last forever, but what we can promise is that if you angle your solar panels for your LED lights properly, you can maximize your potential power gains–almost like sending your lights to the gym for the most rigorous workout possible.

The trick is with angling your solar panels is that one answer isn’t universal for all. What angle you want with your solar panel outdoor lights is actually dependent on where you live as long as your panels are facing south. For instance, if you live in Southern California, home to Greenshine New Energy, you’re best off angling your panels around 33/34 degrees for maximal energy culling potential. Thankfully, these are solar panels for outdoor lights, so it’s not a matter of having a roof that supports that particular angle. Pointing the panels in any other direction will result in less energy gains–it just doesn’t make sense. Do your research online with some handy solar calculation tools and you can find the best angle for where you (or the panels) reside.

What Else is There to Know About Proper Solar Panel Angling?

Oddly enough, the states that receive the most solar power aren’t the sunniest! The Solar Energy Industries Association (SEIA) rates some “cold” states as higher than California and Arizona! Cold weather does not equate to less light. In fact, white snow often times helps to reflect sunlight back onto the solar panels. The panels function more efficiently during winter, too! During the winter, it’s a strong idea to angle your solar panels for your streetlights lower than your latitude. Just be forewarned that reducing the tilt for the panel may cause build-up of snow, and we’re sure you know what that leads to. Snow is actually easy to remove from solar panels if they’re not angled properly to encourage it to slide off.

Keeping these small maintenance factors in mind can help your solar panel street lights last longer when the sun is hidden behind overcast clouds. If you’re still unsure of what the best angle might be for your panels, or if you’re thinking of finally making the jump to solar powered outdoor lights, feel free to contact us and we’ll be happy to assist. Remember, if you’re in a “cold” state, solar panels actually run more efficient and light tends to bounce around more than usual because of the white surface of the snow. It’s just another reason why solar is really catching on across the world–it can be used almost anywhere.

3 Common Problems Solar Adopters Have with Solar–and How to Resolve Them with a Solar Power Generator

solar spot light with separate solar panel

We’ll show our hand of cards today and admit that solar isn’t perfect, it’s just better than fossil fuels. But when constructing a solar lighting project for wherever light must be, there are some small difficulties planners and project managers might run into in regards to solar panel placement and other snags. We’re here to help! Greenshine has been into solar for a combined 3 decades and knows what’s around the corner for a lot of projects. Let us be your eyes for this journey since we know the pitfalls.

Details on a Solar Power Generator

Power Your Outdoor Solar Lights with a Remote Panel

Probably the most apparent “problem” of solar is that it’s unsightly. Even with our decorative lights, a solar panel perched somewhere on the light pole isn’t very attractive. Whatever decorative fixture might be on the top of the pole certainly looks lovely, but the panel itself just sticks out–a dark, flat panel with a generic, unappealing look. Nobody ever said solar power was attractive. But there’s a way you can preserve your light aesthetic, stay green, and save some green all at the same time.

If you power your outdoor solar lights with a remote panel, there’s no need to have the solar panel up on the pole. Using a solar powered generator located in an inconspicuous location can beautify your light pole while harnessing the power of the sun. You get the best of all worlds–cheap, renewable energy (provided every sunny morning), a low-cost technology to power a light, connected to a remote panel generator that hides the ugly part of solar tech. Congratulations, you’ve won.

Relocate Your LED Lights Where Needed with a Separate Solar Panel

We love trees; we’re Greenshine after all, so anything that speaks green to us is a positive aspect of our corporation. However, trees can often be culprits for solar power since they tend to block what solar panels thrive on: the sun. If you have a mini-forest in the area, that can definitely spell doom for the maximum potential of your solar panel power. If your panels are sitting in too much shade, it’s time to think about powering your LED lights with a separate solar panel.

An SPG (solar-powered generator) off-site is perfect for those pesky areas that have very little sunlight because of trees. Find a spot that is secluded but open enough to maximize your solar time, and you can be certain that your solar lights will still be running for days even when the sun ducks behind an overcast sky. Keep your park or public areas populated with trees and well-lit at night with a separate solar panel.

Not Just Lights…But a Wealth of Other Applications

If you’re enjoying your solar spot light with separate solar panel lighting up the night with virtually endless power, don’t forget that your solar generator is portable and can be used almost anywhere. So if your lights are portable as well, remember you can have flexibility with your installations and how they’re powered. In short, an SPG moves with you.

We hope we’ve shed some light (pun intended) on finding workarounds with powering your outdoor solar lights with a remote panel. You can hide them around inconspicuous corners if needed, use them to help solar panels gain charge in the midst of problematic sun-blockers, and you can take them anywhere with you! We’re Greenshine New Energy, a solar LED lighting company dedicated to being lighter on the wallet and the planet. Contact us to learn more. You might just save some money.

3 Questions to Determine if Solar Street Lighting is Best for Your Project

solar street lighting

When discussing options for lighting public areas, solar isn’t always the first thought to come to mind. We know a lot of CFOs and project managers are hesitant to make the switch, and so we’re here to show that solar street lighting might be a more viable route for your energy and lighting needs. Here are three questions to ask yourself if you want to know if solar is right for you. You’d be surprised to hear the differences in traditional vs. solar lighting and how resilient solar fixtures can be.

Solar Street Lighting: The Details

Are you looking for a green alternative?

It’s a bit of a no-brainer that solar energy is a “greener” option. Solar light fixtures are separate from any neighboring city’s power supply system, so they’re “off the grid” in a sense. Maintenance for solar street lighting systems is incredibly low, and they’re self-sufficient meaning they won’t be affected by any nearby power outages or fluctuations. If you’re thinking green, solar is definitely the strongest option.

Does Your Lighting Fixture Have Access to a Power Grid?

We’ve been approached by project managers, CFOs, retail management teams, and project leads to help them build lighting solutions in some of the most unfriendly-to-build areas. Think of implementing an entire solar lighting fixture inside a beautiful park. Bringing power to the park isn’t a two-step process and involves digging a trench to supply electricity to the area, which could potentially destroy beautification efforts and close the park for an extended period of time. Why bother with expensive trenching? Solar skips that with self-contained fixtures.

What Are the Costs with the Scale of Your Project?

The installation cost, operation cost, and maintenance cost of traditional street lights per unit range from $7,000-8,000 over a 10 year period, while the solar street light cost is estimated at $3,500-5,000 over the same period of time. That’s no small chunk of change, and we’re sure the person that has the final say in writing the checks favors spending less over more.

Harness the power of the sun by using solar to light whatever it is you need. There are plenty of hidden benefits we’d love to bring to light (pun intended) with solar, but don’t take our word for it. Feel free to browse the bevy of customer case studies we’ve got on our site, or contact us to learn more.

lumens vs watts

How Many Lumens Do I Need for Outdoor Lighting?

lumens vs watts

What Is a Lumen & Why Does It Matter

In the past, light was measured in watts, which directly measures the amount of electrical power a light bulb consumes. Therefore, people used to expect light intensity to be a function of how much power a light required—higher watts mean brighter light as well as a higher electric bill. Today however, lumen is a popular measurement for light. A lumen is the unit that defines the intensity of light. This unit can be directly related to the amount of light energy that is being emitted from a particular light source. You will find the specifications for how many lumens a particular bulb emits from its packaging.

In short, the difference between watts and lumens is as follows: wattage measures the amount of electrical power a light bulb consumes; lumens measure the actual brightness, regardless of how much power is needed. When choosing outdoor lighting, lumens are a more valuable measurement than watts.

Lumen Requirements for Outdoor Lights

After continuous practice combined with user feedback, we have summarized the different lumen requirements for various outdoor lights.

Types of Lighting Lumens Requirement
Path lighting 100-200 lumens
Step lights 12-100 lumens
Flood lights 700-1300 lumens
Motion sensor lights 300-700 lumens
Pond/pool lights 200-400 lumens
Hardscape lights (on walls) 50-185 lumens
Landscape 50-300 lumens

Solar LED Lighting Stands for the Future

Lumens have substituted watts to become the new light measurement, because a bulb with higher wattage doesn’t mean it will produce a brighter light. Nowadays, we are trying to produce more light using less energy, and we have to consider 2 things: the bulb and the energy.

LED vs Fluorescent vs Incandescent Energy Consumption

The era of incandescent bulbs is gone (read more in the historical evolution of outdoor lighting bulbs), and the winner is the LED bulb. Although some places still use fluorescent lights, LED has become more and more popular due to its long life and extremely low power consumption. The sheet below shows the power consumption of 3 types of bulbs, and there is no doubt that LED saves the most energy.

450 lumens 800 lumens 1100 lumens 1600 lumens 2600 lumens 5800 lumens
LED 6W 9-10W 13W 16-18W 24W 45W
Fluorescent 8-9W 13-14W 18-19W 23W 40W 85W
Incandescent 40W 60W 75W 100W 150W 300W

Solar & LED Win

With the use of LED lights, solar-powered lighting becomes a more viable option, which saves on energy bills in the long run. Solar power is a green, renewable, and sustainable energy source. It will never run out and can provide lighting indefinitely. It won’t produce greenhouse gases which contribute to global climate change. It’s obvious that there are various advantages to solar energy, which is why they continue to grow at a rapid pace.

In conclusion, people today use “Lumens” to measure the light brightness and how much lighting they need. Under the premise of producing the same lumens lighting, LED bulbs consume much less power than fluorescent and incandescent bulbs. What’s more, LED bulbs combined with solar energy saves you even more on your electricity bills. Whether they do it for saving money or being environmentally-friendly, many cities in America have already switched to solar LED lights for their outdoor street lights, park lights, and so on. Please contact Greenshine New Energy for more information about solar led lighting.

Cost Effectiveness: Traditional Street Lights VS. Solar Energy Lights

solar street lights

When thinking about solar energy, what comes to mind first?


It can’t be denied that, in an era of such energy scarcity, solar power will become a hot commodity of the future. In the city planning process, it is necessary to consider the efficient use of energy, which accounts for why more and more cities in the United States are starting to launch solar outdoor lighting projects.

Solar street lights have a huge advantage over traditional street lights. But when city planners choose streetlights, the main reason that stops them from choosing solar powered light is the high price. People take it for granted that the price of solar products is higher than that of ordinary products. But is that really the case? Let’s compare the cost effectiveness of ordinary street lights and solar street lights.

Facts About Solar Street Lights

Purchase Cost

Generally speaking, in the purchase process, we look at price first. From this point of view, solar street lights do not have much of an advantage, because the price is usually twice that of traditional street lights. Due to the capital investment in scientific research and the manufacturing of special materials, the high price of solar street lamps is understandable. However, the purchase price alone cannot be the only means by which to measure the cost effectiveness of solar street lights, and we need to consider the costs incurred in other aspects of the purchase process.

Installation Cost

Installing traditional street lights cost a lot, especially for areas with insufficient electrical infrastructure, such as remote areas or disaster areas. This is because traditional street lights require cabling and trenching to connect to grid lines. In contrast, solar street lights are off-grid, making them much simpler to install.

Operation Cost

The biggest difference between traditional street lights and solar street lights is the energy source. Traditional street lights are powered by electricity (limited and costly), while solar street lights rely on solar power (sustainable and free). City streetlight projects usually require a large number of street lights. And the increased electricity usage adds up fast when using traditional street lights. Therefore, solar powered street lights have the advantage in operational costs.

Maintenance Cost

Maintenance costs must be considered in the planning and construction of urban street lights. Traditional street lights use sodium bulbs, which have a lifespan of about only 5 years. In addition, traditional light bulbs and some electric wires also require frequent maintenance due to thunderstorms or other extreme weather. Solar street lights are far superior in durability to traditional street lights. While they do require eventual battery replacement—the battery has a lifespan of about 5-7 years.

In conclusion, the installation cost, operation cost, and maintenance cost of traditional street lights per unit ranges from $7,000-8,000 over a 10 year period, while solar street light cost is estimated at $3,500-5,000 over the same period of time. The extra costs associated with traditional street lights make their advantage of lower purchase price disappear.

After comparing the cost effectiveness of traditional street lights and solar street lights, you can now choose solar street lights with confidence. In fact, the savings are just one small benefit of solar street lights. The greatest benefit is that your city will start to use NEW, GREEN and SUSTAINABLE lighting.
