Solar panels are the most valuable part of solar street lights.

          Its role is to convert the solar radiation capacity into electrical energy, which is sent to the battery for storage. Among the many solar cells, the more common and practical ones are monocrystalline silicon solar cells and polycrystalline silicon solar cells. In the eastern and western regions where there is sufficient sunlight and sunshine, it is better to use polycrystalline silicon solar cells because the production process of polycrystalline silicon solar cells is relatively simple and the price is lower than that of single crystal. In the southern regions where there are more rainy days and less sunshine, it is better to use monocrystalline silicon solar cells because the performance parameters of monocrystalline silicon solar cells are relatively stable. If the local is based on the short characteristics of the average sunshine (the calculated average number of hours is about 3.8H / day), there are many rainy days in winter. Comprehensive comparison and local geographical environment analysis We use monocrystalline silicon solar panels, solar modules use a total of 160WP solar cells to ensure that the continuous rain and rain for 20 days can be normally lit. In order to give full play to its performance and ensure the stability of the system.
