How Does Solar LIghting Work?

Solar lights at dawn

1 Dawn: 

The voltage from the solar panel raises and gets higher than it was during the night. When a certain voltage threshold is reached the controller will detect this and turn off the light. The battery will then being to charge itself from the discharge that occurred when it was powering the light.

solar lights at night

4 Night time: 

The voltage from the solar panel is lower than the pre-set value. After the controller recognizes this situation, the electricity is drawn from the charged battery and continuously powers the lamp fixture. The light will stay on all night until the sun rises and the cycle is completed.

2 Day time: 

Throughout the day the solar panels will convert the solar energy from the sun into electricity which will charge the battery. The intelligent solar controller charges the battery throughout the day and controls the current to ensure that the battery is not overcharged.

solar lights at dusk

3 Dusk: 

As the sun sets the photocell that is built into the panel will sense the voltage drop as the panels are no longer taking a charge. The battery has been charged throughout the day and is now ready to discharge and provide electricity for the lamp and turn it on. If there is inclement weather, there are at least three days backup for Greenshine’s system.

Cost Comparison Between Solar vs. Traditional Lights

As solar lights have increased in popularity over the last 5 years due to emerging green technologies and rising energy costs, an important question is being raised: how much do solar street lights cost compared to traditional street lighting? To solve this mystery, our expert team of engineers gathered the necessary information to provide a cost analysis of each lighting system.

The Light

Traditional street lighting is defined as any electrical light used for street lighting, which is most commonly metal halide and high pressure sodium lights. The average cost of one light, including the lighting fixture, pole, and base, averages at $1500.

Solar street lights are fixtures that use a solar panel to garner electricity. They are off-grid and can be installed in remote locations. Because of the advanced technology required for solar lights, they are more expensive, averaging about $3000 per light.  


The biggest difference between the cost of traditional and solar lights lies in the installation.

Traditional lights are connected to a standard electrical grid to garner their power, which requires trenching and underground wiring. When adding in labor fees, this process would cost consumers about $120 per foot. The average cost of installation for traditional lighting would then be around $4500.

Because solar lights are autonomous and off the main grid system, consumers avoid the long and costly process of trenching and wiring. The cost of installation reduces significantly as a result, pricing around $1500.


Solar lights require less maintenance than traditional lighting systems. The typical lifespan for a traditional street light averages around 5,000-8,000 hours, while solar LED lights last 5-7 years.

While solar lights get repaired less frequently, the cost of each repair is higher. The battery of a solar light needs to be changed every 5-7 years. The cost of 2 batteries and labor for those changes averages around $1000. This is only slightly higher than the cost of standard lights which is about $800.

Energy Bills

Since solar lights gather their energy from the sun, there are no energy costs! Standard lights, on the other hand, accumulate about $1500 in energy costs over 10 years.

Incentive Programs

Solar lighting systems are also heavily subsidized to encourage the use of green energy. According to the NC Clean Energy Technology Center, there are about 200 financial incentive programs for solar alone. Both the private and public sector offer incentives to use solar, but each entity differs in the amount and type of incentive they provide. For example, North Carolina provides a 35% tax credit against the total cost of the system, while the Federal government offers 30%. For more information on the solar incentives, rebates, tax credits, and grant available, visit

The Verdict

When comparing the total costs of traditional and solar lighting, there appears to be a clear winner. Overall, solar street lights cost around $5500 over 10 years, while standard costs a steep $8300. 

In the battle of the lighting systems, technology and innovation won. While traditional lighting systems may have won some battles, solar lights won the war.

Solar Lights for Parking Lots: The Design Basics You Need to Know

There are a few basic design principles of solar parking lot lights. To gain deeper insight into a cost-effective solar PV system design, here’s what you need to know.

What is Solar PV System?

Solar PV system uses photovoltaics (PV) to transform sunlight into electricity. Solar-powered photovoltaic panels, also called modules, contain photovoltaic cells. These cells convert incoming sunlight into electricity that can either stored for later use or directly supply a home or a business with renewable energy.

Solar energy is a clean and reliable source of electricity that has a vast range of applications. With its high rate of return, solar is considered a great investment opportunity and is now being embraced by many industries across the board.

Components of Solar Outdoor Lights

Depending on the system type, application, and site location, a solar-powered system consists of different parts. The main components are solar PV panel, LED light, solar charge controller, inverter, battery, and pole.

  • Solar PV panel consists of photovoltaic cells that are wired together and convert sunlight into direct current (DC) electricity.
  • Solar charge controller regulates the voltage and current that is coming from the solar panel. It uses the panel to charge the battery, keeps it from overcharging and prolongs the battery’s life span.
  • Batteries store the energy that can later be used to supply lights and various electrical appliances when there is a demand.
  • LED light provides high-quality illumination using energy produced by solar panels.

Power Consumption of Your Solar System

When designing a solar parking lot lights system, it is important to calculate the total power and energy consumption of LED lighting. To find out the total consumption of your solar system, you should calculate total watt-hours per day for each part that will need to be supplied with solar power.

Tip: When making this calculation, you should also take into consideration the energy lost in the system for the most accurate results.

The Size of the Solar Panel

The number and size of the solar panels are important for the optimal performance for solar parking lot lights. They come in different sizes and types, each outputting a different amount of power.

To find out the right sizing of your solar panel, you should calculate the total peak watt needs. The peak watt (Wp) produced will depend on the size of the PV panel and climate of parking lot location.

You should calculate the total Wp rating needed for solar PV panels and number of solar panels required for the system so you will get the minimum number of solar panels for your parking lot.

The Best Solar Lights for Parking Lots

Solar-powered LED lights are an energy efficient and reliable solution for solar parking lot lights. To get the most accurate and cost-effective system, you should seek assistance from professionals. Choose a reliable company with a vast experience in developing and manufacturing solar outdoor lighting solutions.

How Do Solar Panels Work?

Over the last 10 years, the rapid growth of the solar industry has demanded attention. Large agencies such as Tesla and the European Union are embracing solar as the wave of the future. From solar panels on rooftops to solar street lights, the solar is now a major player on the world stage.

With all this talk about solar, have you ever wondered how a solar panel actually worked? Here’s a little introduction on what solar panels are and how they work.

The Basics

Depending on the system type, application, and site location, a solar-powered system consists of different parts. The main components are solar PV panel, LED light, solar charge controller, inverter, battery, and pole.

  • Solar PV panel consists of photovoltaic cells that are wired together and convert sunlight into direct current (DC) electricity.
  • Solar charge controller regulates the voltage and current that is coming from the solar panel. It uses the panel to charge the battery, keeps it from overcharging and prolongs the battery’s life span.
  • Batteries store the energy that can later be used to supply lights and various electrical appliances when there is a demand.
  • LED light provides high-quality illumination using energy produced by solar panels.

What are Solar Panels Made Of?

Solar panels are one of the main components of a solar outdoor lighting system. While there are several types of solar cells, typically that are comprised of multiple small grouped units called photovoltaic (PV) cells.  These cells are made of two layers of semiconductor material typically comprised of silicon crystals.

Because silicon is a poor conductor of electricity, the bottom layer of photovoltaic cells is doped with boron, which facilitates a positive charge (P). On the other hand, the top layer is doped with phosphorus, adding electrons with a negative charge (N). Electron movement between the two layers with opposite charges produces an electric field.

Most PV systems are based on individual square cells that produce very little power, which is why they are linked together as panels or modules. During solar panels installation, solar panels can be used individually or wired together into larger solar arrays to produce the desired electrical output.

How Do Solar Panels Work?

Solar PV system uses photovoltaics (PV) to transform sunlight into electricity. Solar-powered photovoltaic panels, also called modules, contain photovoltaic cells. These cells convert incoming sunlight into electricity that can either stored for later use or directly supply a home or a business with renewable energy.

Solar energy is a clean and reliable source of electricity that has a vast range of applications. With its high rate of return, solar is considered a great investment opportunity and is now being embraced by many industries across the board.

PV cells convert sunlight into electricity. When particles of light called photons hit the surface of a solar cell, they knock electrons loose from their atoms. When positive and negative charges are separated, an electric field occurs.

As electrons flow through an electrical circuit from one layer to another, they generate a flow of electricity. After the panels convert the energy to direct current (DC) electricity, an inverter converts it into alternating current (AC) electricity.

Alternating current is the type of electricity that consumers use when they plug their appliances into a wall socket. Only after it is converted to AC, electricity can be delivered to a business or a residence.

Solar panels and Outdoor Lighting

With modern technology, large corporations and municipalities are embracing solar and are investing in this growing infrastructure. Photovoltaic cells require no maintenance, produce no greenhouse gas emissions, and are environmentally friendly. They are also easy to manage as they turn off and on automatically. Solar panels provide enough electricity both on sunny and cloudy days, and charge the batteries that can later power your residential or commercial solar lights during the night. With current technology, most solar systems use LED lighting as opposed to commercial for the advantages in technology.

Installation Tips for Solar Powered Lights

Solar Powered Street Lights for Sale Homeowners and businesses interested in reducing their energy consumption, maintenance costs, and energy bills are going solar because of it s sound investment. The initial costs can be reduced by looking for high-quality solar powered street lights for sale.

There are, however, several things to watch out for in order to make the most out of solar outdoor lighting. Here are a few guidelines on how to safeguard your off-grid solar outdoor lighting against failure.

Choosing a System

The performance of your solar system may be considerably decreased due to poor design and improper installation of luminaries. Insufficient power quality can also be the cause of problems.

You might select your outdoor lighting based on price or want to purchase explicitly solar powered street lights for sale. You should consider other factors and think of a solar system as a whole.

An off-grid solar system needs to be designed and selected based on various calculations. Some of the factors that should be taken into account are the brightness of LED lamps, the life span of every component, autonomous battery storage, and the longest working days without sunshine. The size and quality of the photovoltaic cells will affect the efficiency of solar panels.

Avoiding the Shade

Solar panels gather the sun’s energy and convert it to electricity. Any excess electricity generated during the daytime is stored in the battery bank, which is then used to power the light fixtures during the night.

The amount of energy generated by solar panels depends on the amount of sunlight received. Therefore, it varies by season and during the day. There’s no better place to install solar panels than a sunny country like California.

Even in regions with such vast solar resources, it is important to avoid installing solar lights in the shade. Shade will impede the solar panel’s power production capability. And it is the amount of sunlight that has the biggest influence on the performance of solar lighting.

To get maximum amounts of sunlight which will later be used to power the light fixtures, solar panels should be placed in direct sunlight.

Pointing Solar Panels at the Sun

As we previously mentioned, the more exposure to the sun your solar panel has, the more electricity will be generated and stored in the battery. Solar panels that are oriented towards the Sun or aligned with it intercept the vast majority of sun rays.

The Sun moves from east to west, and the conventional wisdom is that the optimal direction to face solar panels is south. There has been a lot of debating but recent studies show that it is best to point your solar panels somewhere between south and west, so that the panels get maximum sunlight.

Location of the Light Fixtures

Solar street lights switch on and off automatically, and solar panels need to be installed above the light fixtures or in a remote location away from them. Otherwise, the light from the fixtures will interfere with the light sensor and the automatic control signal of street lights.

The sensor is designed to detect the intensity of light. For example, if the amount of light is less than 80 percent, the automatic street light control will turn the lights on. In case the light fixture is located just above the solar panel, the system will think it is daytime and turn the lights off.

Regular maintenance

Though solar outdoor lighting requires much less maintenance compared to conventional lighting solutions, it still needs to be maintained. The average life expectancy of LED lamps can go up to 100,000 hours, while the battery life span is approximately 5-7 years.

Proper maintenance can help extend the life of your solar system’s components. To keep your off-grid solar system at its best, taking preventative measures and scheduling maintenance is needed as much as repair services.

A Beginner’s Guide to Solar Panel Installation

Solar energy is a renewable and inexhaustible resource. It converts sunlight into electricity using photovoltaic solar panels. Many people are adopting solar as a cost efficient and reliable source of energy. Are you considering installing solar panels, but don’t know where to start? Here’s our little guide to help you install a solar powered system.

The Solar Panel

A solar panel has 4 main components:

  • A photovoltaic panel to install directly in a frame on the tiles or into the roof replacement coverage.
  • Wires to carry the electricity. They have an anti-UV treatment.
  • An inverter to convert the DC high performance current delivered by the low voltage panels alternating current. .
  • A electricity meter to measure the energy produced by the user.

Initial Inspection

First, analyze how you are currently using electricity. Take a deeper look into your electricity bill to find how you allocate your electricity bill in the house. Then, you should decide whether or not your solar panel should cover the use of energy of your entire house or only a part of it. After checking these points, you will be able to determine the most suitable for your need.

Tip: Unplug your devices! Did you know that even if you turned off your electric appliances they still consume electricity? They will stay active unless you plug them out, so your electricity bill will be higher than what you should be paying.

Roof Inspection

After you checked your power consumption, analyze your roof’s measurement to validate the type of solar panel you can install there. Because of your roof specific size, you should be careful on the solar panel’s dimension and its output to maximizing the space on your roof.

Solar Panel Installation

Hire a professional. They are certified and know all the intricacies of the installation. Make sure that the roof, ground mounting, or tracking system you are using is engineer certified for the area you are in. For example, if you live in an area with high climate variability, the mounting system and mounting brackets also need to be sufficiently weather resistant.

Solar Inverter Efficiency

The power inverter is a box installed between the panels and your appliances that converts the generated DC to AC, which is suitable for use in your home. Their efficiency will have a direct impact on the payback time of your system, so look at the inverter efficiency before purchasing a system.

Prices Benchmark

Price is always an important factor when you want to buy a product. Quality-price ratio is an important element to include in your equation. The average price of a solar panel installation is typically $7-9 per watt. So, a 5 kW system would cost around $25,000-$30,000.

Many utility companies offer incentives to for solar panel installation, so look for price reductions or subsidizes available for your home.

Warranty Length

Be careful of the solar panel’s warranty length. Try to aim between 5-10 years, as it will cover all the short term issues you may encounter.

Which Industries Can Benefit From Solar?

solar panels on the roof - industrial solar streetSolar technology is continually adopting and evolving to support businesses in all their efforts. With modernization, tax incentives, and falling costs, many businesses are taking advantage of solar energy and reaping the benefits. Apart from solar panels on rooftops and solar street lights, many unexpected industries can utilize solar power systems to grow their business, including the manufacturing, commercial, and agricultural industry.


Manufacturing companies are the ideal candidates to implement a solar energy system. They usually operate in large buildings with lots of roof space that can be put into use. These expansive open areas are perfect for setting up solar panels. Plants are typically situated far from tall buildings and the clusters of skyscrapers in city centers. This means they can benefit from extended periods of unimpeded sunlight. The more sunlight the panels capture, the more electricity they can produce.

The rooftops are not the only location where solar panels can be installed. Industrial solar street lights and parking lot lighting will keep the area well-lit and contribute to lowering electricity bills. Manufacturers’ overall energy consumption contributes to higher costs and greater pollution and the manufacturing process generally uses a considerable amount of electricity, making solar a perfect fit for their energy needs.


Commercial companies, such as department stores or business offices, will also see a high return on investment. As demand for power and energy costs rise, buildings of high energy efficiency with integrated renewable energy technology will become highly sought after.

With increased resale value, available rebates, and production incentives, embracing solar energy is an excellent investment for commercial and industrial electricity users. California is the state with the most programs for going green in the commercial sector. Commercial businesses can use their vacant rooftop space to unlock the huge potential of solar energy, as it will save businesses thousands of dollars over time on electricity costs.


Farms and rural businesses use tremendous amounts of electricity, but fail to realize the potential impact of solar’s cost-effective solutions on their rooftop space.

Solar systems are reliable, durable and have low maintenance requirements. Businesses may wonder if the installation cost is too high. Though the initial investment can be sizable, solar systems are now more affordable than ever.

The government has encouraging measures and tax incentives to support businesses that invest in a solar energy system. The USDA Renewable Energy for America Program (REAP) provides an amazing opportunity for farms and rural businesses.

If they want to install renewable energy systems or make energy efficiency improvements, agricultural producers and rural small business can see if they are eligible for grants from USDA and attempt to get the maximum grant amount for their solar projects.

Commercial Solar Lights or Low Voltage?

If you are looking for alternatives for standard lighting on your commercial property, most contractors will offer you the choice between low voltage lights and commercial solar lights. If you are wondering what the difference is, and which one is better for your needs, here is a handy comparison of the two.

Commercial solar lights

Solar lights require no cables or access to the electrical grid, since they come with their own power generating solar panel, as well as batteries to store the energy collected during the day. Another advantage of solar lights to regular ones is the ease of installation. Once you have decided where you want to put them, you just do it, with no hassle around electrical installations. Similarly, if you want to move or remove them, the process is as easy as picking them up and moving them to the desired location. Commercial solar lights are now available in a variety of shapes, forms and sizes for a myriad of applications. The downside of solar lights is that they require the sun to function properly, meaning that the site you pick for your solar lighting fixture needs to be exposed to direct sunlight in order to charge the battery.

Low voltage

Low voltage lights are not much different from regular lights. The key difference is that regular lights work on the standard grid voltage of 110-120 volts, whereas low voltage ones work on just 12 volts. This is made possible through technological advancements over the recent years. Incandescent lights require high voltage since the majority of energy used for them is wasted on heat. Low voltage lights use more advanced technologies which enable better energy management and less waste. However, since your house is powered via an electrical grid of 110-120 volts, installing low voltage lights does mean installing a transformer as well as special cables and light fixtures.


As mentioned before, solar lighting is a lot simpler to install. It does not depend on any external power grid and requires no further installation after it has been set up. The only concern you have is that your solar panel gets plenty of sunlight during the day. Low voltage lighting, on the other side does require all of the above. You will need to have constant access to the grid, as well as dig through the area you are lighting to put cables in. Furthermore, the transformer will also need to be installed. So, if you are looking to make as little change to the scenery as possible, solar lights seem as a better option.


There is not much maintenance involved in any of the two systems. Apart from changing the light bulbs once they break down (which is rare for both systems) and occasional cleaning to keep the light output to the maximum, there isn’t much that needs to be done. The solar panel also needs to be kept clean to ensure the best sunlight absorption and longer battery life.

Which is better?

There is no single answer to this question. What you need to do is carefully measure your needs, your budget and the expected results. There are three key reasons people put on landscape light: security, ease of movement, and decoration. If you are looking for something that requires less maintenance that easily connects to the main power grid, choose low voltage. If you are looking for a long-term solution that will save you long-term costs while also does not detract from the natural environment, choose solar. Either way, contact Greenshine for a consultation on your energy needs.

Useful Tips for Landscape Pathway Lighting

Pathway lighting - landscaping tipsNo landscaping venture is complete without decorative pathway lighting. If you are planning on modeling your backyard or any similar project, you might want to consider installing solar pathway lights as a cost-effective and beautiful solution for your lighting needs. Here are some tricks and tips you might appreciate before you actually install these.

Spacing Your Pathway Lighting

The most common use of solar landscape lights is pathway lighting. Prior to installing your solar lights, you need to make sure that the place you intend to put solar lights gets plenty of direct sunlight. Then, set the distance between two solar lights as it is up to you to decide whether you want the path to be brightly illuminated (recommended for difficult terrain), or if you want to use solar lights only as accent lights.

Panel Angling

Typical landscape lights are known as bollards. These have the solar panel on the top of the fixture and LED lights just below it. When you are installing these light fixtures, you need to make sure that your solar panel gets as much direct sunlight as possible, so you will have to consider the angle at which to put your light fixture. This can vary depending on your geographic location as it affects the time and intensity of light on your property. If needed, use a solar lighting companies for the best advice.

Mind the Sensors

The majority of contemporary solar lights are turned on or off automatically by measuring the surrounding light levels. You need to be careful not to place solar lights too close to any other source of artificial light. This includes street, garage, and porch lights. If it detects the light coming from another source, the solar light will not activate. If your solar light is not functioning properly, check whether that is the problem before you contact the maintenance company to check it out.

Cleaning and Storing Solar Lights

When storing solar lights, you need to follow some basic rules. The most important one is keeping them dry, since electronics and batteries do not react well to moisture. Do not to keep them in darkness. If they cannot recharge and discharge, the batteries tend to lose the ability to hold charge. As for cleaning them, the most important part to keep clean is the panel itself. You want to keep the debris off of it as much as possible in order to ensure the best possible performance. A dry cloth and some soapy water will do the trick.

Solar lights are often mentioned as a great alternative for parking lots and industrial complexes, but they are also used for these smaller and more creative applications.
