Solar Photovoltaic (PV) Systems

Photovoltaic (PV) solar electricity systems have captured a lot of interest as the system components have grown more mature, capable, and reliable. 

 The references and articles below provide PV system b , examples of the four common types of PV systems used to generate electric power, reviews of PV system components, lots on how-to build your own PV system, and a few interesting "other" PV systems.

 Contrary to popular belief, in most areas it is perfectly legal and relatively straight forward to do your own PV -- we did...

Electricity from solar generated steam

The solar energy power system has two ways of independent and parallel, the independent system uses battery as energy storage unit, batterys lifetime around 5~10 years, the scrap are a major source of pollution, so this kind of power most used in the place of  short and less electricity. Grid parallel power system is form of the same frequency and phase alternating current with  solar energy DC power inverts to AC electricity from the grid owner regarding technical feed-in conditions and connection to public grid. supply electric by electricity grid, it is an useful effective complement for building electricity.
