How does the solar street lamp functions?

Solar panel may be the core a part of the solar street lamp, and it’s also probably the most beneficial a part of the solar energy. The function is usually to convert the radiation of the sun for the electric energy, or for the storage of the battery. There are three types of solar cells, like single crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. Inside the east in the sun, the solar cell is good, plus the solar cell is improved, simply because the solar cell production procedure is comparatively easy, the value is reduced than the single crystal.

Inside the rainy days, the sun isn’t rather adequate in the south, the usage of single crystal silicon solar cells, because the overall performance parameters from the single crystal silicon solar cells are fairly stable. Amorphous silicon solar cell within the outdoor sunshine is insufficient, since the amorphous silicon solar battery of solar light illumination needs is fairly low as a result of input power of solar photovoltaic power generation program is extremely unstable, so the common require to configure battery technique to function. Lead-acid batteries, Ni-Cd batteries, Ni-H batteries. The selection of battery capacity in general to stick to the following principles: very first of all in the premise which can meet the night lighting, the power within the daytime, the solar battery element as stored, but in addition able to satisfy continuous overcast and rainy night lighting electrical power storage. Battery capacity is too small can not meet the needs with the night lighting, the battery is as well significant, around the a single hand, the battery is normally within a state of loss, affecting the battery life, although causing waste. The battery really should be matched together with the solar cell and electric load (street lamp). Is usually utilized to establish the connection amongst them.

The solar cell energy should be four occasions larger than the load power, the method can function generally. The voltage on the solar battery for the working voltage of 20~30% battery more than, so as to assure the regular battery charged. The storage battery capacity has to be 6 occasions higher than the load every day consumption is suitable.
