Solar panel is the core part of the solar street lamp, and it is also the most valuable part of the solar energy. The function is to convert the radiation of the sun to the electric energy, or to the storage of the battery. There are three kinds of solar cells, such as single crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. In the east of the sun, the solar cell is good, and the solar cell is better, because the solar cell production process is relatively simple, the price is lower than the single crystal.

In the rainy days, the sun is not quite enough in the south, the use of single crystal silicon solar cells, because the performance parameters of the single crystal silicon solar cells are relatively stable. Amorphous silicon solar cell in the outdoor sunshine is insufficient, because the amorphous silicon solar battery of solar light illumination requirements is relatively low due to the input energy of solar photovoltaic power generation system is very unstable, so the general need to configure battery system to work. Lead-acid batteries, Ni-Cd batteries, Ni-H batteries. The choice of battery capacity in general to follow the following principles: first of all in the premise that can meet the night lighting, the energy in the daytime, the solar battery component as stored, but also able to satisfy continuous overcast and rainy night lighting electrical energy storage. Battery capacity is too small can not meet the needs of the night lighting, the battery is too large, on the one hand, the battery is always in a state of loss, affecting the battery life, while causing waste. The battery should be matched with the solar cell and electric load (street lamp). Can be used to determine the relationship between them.

The solar cell power must be 4 times higher than the load power, the system can work normally. The voltage of the solar battery to the working voltage of 20~30% battery more than, in order to ensure the normal battery charged. The storage battery capacity must be 6 times higher than the load daily consumption is appropriate.
