Solar Panel
We use Germany Solarword efficiency mono crystalline silicon solar panel & United States brandSunpower efficiency mono crystalline silicon solar panel. The photoelectric conversion efficiency can reach 20% and 22%. Lifespan of the solar panel is 25 years.
Controller
The controller is developed by our engineering team. We also have applied the patent successfully already. The conversion efficiency of our controller is 95%, while the average efficiency of other controllers are only 60% -70% for the whole market. Lifespan of our controller is 10 years.
Lithium Battery
We use the lithium iron phosphate battery (LiFePO4) which is environmentally friendly. It is inside the product to avoid being stolen. Its lifespan is more than 5 years.
LED Chips
United States brand Bridgelux 45ML is used for our solar street light, and the lumen of each led chip is 150LM. Its lifespan more than 10 years.
