Frequently Asked Questions About Solar Lighting

How do solar lights work?

Solar lights contain a solar panel that captures sunlight during the day and converts it into electrical energy, which is stored in a rechargeable battery. The battery then powers the light at night, providing illumination without the need for an external power source.


A solar lighting system consists of various components, including an intelligent controller that prevents the solar panel from overcharging the battery bank. It also senses when there is no longer energy from the sun and automatically turns the LED light on using a portion of the stored energy in the rechargeable battery.

What are the benefits of using solar lights?

There are several benefits to using solar lights, including that they are energy-efficient, cost-effective, and environmentally friendly. Solar lights also require minimal maintenance and can be installed in areas where it would be difficult or costly to run electrical wiring.

How long do solar lights last?

The lifespan of solar lights varies depending on the quality of the product and the conditions in which it is used. However, most high-quality solar lights can last for more than 10-years with proper maintenance. It’s important to keep the solar panel clean and free of debris and to replace the battery when needed to ensure optimal performance.

Can solar lights be used in areas with limited sunlight?

While solar lights require sunlight to function, there are still options available for areas with limited sunlight. Some solar lights have a higher efficiency solar panel and battery. It’s important to select the appropriate type of solar light for your location and lighting needs.

How bright are solar lights?

he brightness of solar lights can vary depending on the product and the application. Some solar lights are designed for decorative purposes and provide a soft, ambient glow, while others are designed for security or functional lighting and provide a brighter and whiter illumination. The brightness of solar lights is typically measured in lumens, so it’s important to check the product specifications to determine the appropriate level of brightness for the intended application for the project.

What is the lifespan & warranty of the product?

Our solar street lights have been optimized to ensure a 12-year lifespan on the whole product. Rather than guaranteeing each component independently, we guarantee the whole product for 10 years under normal conditions of use (1 cycle per day, operating temperature range from -40°C to 70°C).

What is a lighting profile?

We offer several lighting profiles allowing precise management of the energy available in the battery. The night is divided into 3 phases: beginning of the night, middle of the night and end of the night. By modulating the lighting intensity over these three periods, our solar lighting provides you lighting 365 nights a year without any interruption in service during the night.

Can I convert an existing traditional street light to run on solar power?

Absolutely! The pole may be able to be reused for a solar lighting system. The light fixture itself would have to be replaced with a fixture built to run on solar power. Check out more about Retrofitting here. 

How do I know what product is best for my lighting needs?

Our Engineers assist you in the development of your project every step of the way. To do so, they carry out various studies (photometry, autonomy calculations) that allow you to determine the lighting management program that best suits your needs. These studies are conducted according to the specific criteria of your project:


– Project location (with GPS coordinates)

–Weather data history

– Application to be lit

– Area to be lit (length and width, in the case of a road)

– Desired pole height

– Lighting levels needed


Our SunnAPP© application allows you to modify the lighting profile at any time during the use of the product if it is no longer suitable. It offers different available profiles, according to your location.

How often will a solar light need to be maintained?

Solar-powered outdoor lighting is virtually maintenance free, since the batteries require no regular service. Every EverGen system includes free remote monitoring, which uses GPS to pinpoint system faults and notifies you of the location via email. A standard 10-year warranty is also included with every EverGen. Upgrades are available for a 10-year battery warranty and dashboard-status remote monitoring.

What are the steps in your system check?

Every project runs through a series of comprehensive and real-life simulations to determine the best, most cost-effective solar lighting system for a specific location.


Our sizing engines crunch thousands of data points, backed by 20 years of NASA data, to ensure your system works for the long term—exactly as planned.
