The annual power generation can be calculated using the formula: Annual Power Generation = Solar Radiation at Specific Angle × Module Installation Capacity × Comprehensive Efficiency Coefficient. [PDF Version]
Solar street lights charge and generate electricity at the same time
A solar street light converts sunlight into electricity during the day and uses this stored energy to power LED luminaires at night. The solar panel charges the battery through a controller, which also manages when the light turns on and off and how bright it is. [PDF Version]
