Solar panels are the core of solar street lights and the most valuable part of solar street lights. Its function is to convert the solar radiation capacity into electrical energy, or send it to a lithium storage battery for storage. Among the many solar panels, there are three types of monocrystalline silicon photovoltaic panels, polycrystalline silicon photovoltaic panels and amorphous silicon photovoltaic panels.

In areas where sunlight is abundant, 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 areas 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.

 Amorphous silicon solar cells are better in the case of insufficient outdoor sunlight, because amorphous silicon solar cells have lower requirements for solar lighting conditions.
