How long can a solar street light be used?
- Solar street light is an independent lighting system, also said that their power for lighting, do not have access to the power grid, solar panels during the day to convert light energy into the battery, the battery at night to supply the power to the light source Lighting, is a typical power generation discharge system. For solar panels, we all know that is a power generation equipment, he is made of pure silicon as the main material, life is very long, at least 20 yearss

- the controller of the waterproof, the controller is generally installed in the lampshade, the battery box, the general will not water, but in the actual project case the controller terminal for the rain along the cable into the controller caused by short circuit. So the construction should pay attention to the internal cable bent into a "U" font and solid type, external connection "U" type, so that rain can not fall into the controller caused by short circuit, the other can also be inside and outside the interface coating Thes

What are the advantages of solar led street light?
- And in the winter only half, cloudy day is generally only about 1/5, so that the energy density is very low. Therefore, in the use of solar energy, you want to get a certain conversion power, often need a considerable area of a collection and conversion equipment, cost higher.s
What are the components of the solar street light
- Solar cell components generally use single crystal silicon or polycrystalline silicon solar modules; LED lamp head generally use high power LED light source; controller generally placed in the poles, with light control, time control, overcharge and over discharge protection and reverse protection, more High-level controller with more than four seasons to adjust the lighting time function, half-power function, intelligent charge and discharge functions;s
