To understand the components of solar street lamps, there are relatively more detailed varieties of components. There are mainly panels, solar batteries, solar controllers, light sources and other corresponding components. Therefore, when selecting solar cells, we should also consider the material, color difference, charging current, open circuit voltage, conversion efficiency and other factors of photovoltaic panels. When selecting the storage battery, we should know the detailed type, discharge rate and working environment. Of course, when choosing the controller, we should also understand the waterproof function.
