What is the working principle of a solar street light?
Solar street lights work by collecting solar energy through solar panels, converting it into direct current (DC) electricity, which is then stored in batteries. A controller then controls the on/off and brightness of the LED lights. The controller automatically adjusts the lighting duration and brightness based on weather and light conditions, achieving energy savings.
Solar street lights compared to AC grid street lights?
There is no need to connect to the grid, and it is zero cost to use. There is no need to lay cables, and it is easy to install, saving cost and time. Each solar street light is independent and can be installed in any sunny place. It has automatic ON/OFF and is maintenance-free. Solar street lights are DC supply, and the working voltage is less than 36V, which is safer. The initial cost of solar street lights is 30%- 50% higher than that of AC street lights.
How about the lifespan of solar street lights?
25 years for the battery and 5 years more for the LED light, battery & controller.
How often does the lithium battery need to be replaced?
The battery lifetime depends on the quantity and is affected by the DOD(depth of discharge). VER SOLAR uses branded battery cells and manages the DOD strictly, ensuring the battery life. Generally, our LFP battery sustains 7 years more, and 5 years more with the ternary lithium and gel batteries.
Can solar road lights work on cloudy or rainy days?
VER solar road lights can support multiple rainy days. The control system has intelligent monitoring of battery capacity and adjustment functions, benefiting from this anti-power outage function, which keeps the light working every day.
Does the solar panel need maintenance?
Solar panels should not be covered with heavy dust, sand, or bird droppings, which will lower their generation efficiency, so they need to be cleaned regularly. Generally, they need to be cleaned every 8-10 months in rainy areas and every 3-5 months in dry and dusty areas.
Are solar street lights easy to break? What is the warranty of your products?
Through the continuous efforts of our technical team, with the additional complete testing equipment and procedures, the failure rate was 0.3% in 2024 during the warranty period. At present, we provide customers with 3 -5 years of warranty at different prices.
Why do the newly installed solar street lights not work?
It is common for the newly installed solar street light to work briefly at night because the battery’s initial power is only 60%. For transportation safety, generally, after 2-3 days of installation, the lighting time will return to normal.
If it doesn’t work all night, please check the wiring and the working status of the controller indicator light, and contact our sales engineer to determine the problem.
What is an all-in-one solar street light?
An all-in-one street light integrates the solar panel, battery, LED light, and controller. There is no wire outside, and installation is very simple—you need to fix the lighting fixture on the pole.
What is all in 2 solar street lights?
An all-in-one solar street light integrates the battery, controller, and LED light source inside the lamp body, except for the solar panel, making it easy to install. This design allows the solar panel to be angled in the direction of the lighting area to get the maximum solar radiation while the LED light remains in that direction.
