Poles: As for solar street lights are in the outdoor environment for long-term, can not avoid the wind and sun, which having quite high requirements on the poles of the process. After a high standard of hot-dip galvanized Q235 steel, and then spray by electrostatic, can without rust for 20 years. Of course, the thickness is also a hard target. Generally, 6 meters of poles need thickness more than 2.5mm. Light source and controller: These two are the core parts of lights, a good light source with high lumens and low color attenuation, especially the energy-saving effect of LED light source is in line with the current road of green development. The controller is the brain part of the whole system, it has to control the work of other various parts, whether the controller is good or bad is the key to the whole solar street light. Solar panels and batteries: solar panels as the part of the absorption of light, batteries store up the solar energy absorbed by the solar panels. Solar panels are divided into two kinds of monocrystalline and polycrystalline, because of their different conversion efficiency, cost is different, polycrystalline is more relatively economical. The battery is divided into two kinds of batteries and lithium batteries, in terms of life, lithium battery more stable, but the lithium battery have the higher requirements on the ambient temperature, this need to be considered under various aspects.
