Photovoltaic is a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect. They are simple to install and maintain in actual use.

　 Xinxiang Providence Solar Photovoltaic Power Plant When light strikes the PV panel, some of the photons are absorbed by the silicon layers. The photons cause electrons to be released from the silicon crystal, and those electrons "wander around" looking for somewhere to attach themselves. Some of the electrons are freed from the bottom layer, and they find their way through the junction into the top (electron rich) layer. Some of the electrons are freed from the top layer, and since they cannot travel to the bottom (electron poor) layer, and are being "crowded" by new electrons from the bottom layer, they are left free to be collected by electrical contacts on the surface of the top layer. Those collected electrons are routed through an external circuit, providing power to the electrical system attached to the panels. The circuit is completed when the electrons return to the bottom layer of the PV panel, find "resting spots" in the electron poor bottom layer, and wait for the next photon to shake them loose.

1、Solar power is safe and reliable enough and it will never run out, so it can against those outside shocks like energy crisis and fuel market fluctuation.
2、Solar energy is available everywhere so that the loss in long-distance transmission can be avoided.
3、Photovoltaic power uses no fuel and has low operation cost.
4、 Solar power units have no moving parts and it is not easy to damage, especially suitable for unattended operation.
5、Photovoltaic power produces no emissions and does no harm to environment. It is the ideal clean energy in the new century.
6、Solar power generating system has advantages of low energy consumption and short construction period. The capacity of solar matrix is adjustable to meet the changeable load.
