Solar energy generates electricity, including solar photovoltaic generators and large thermal electrical plants. Photovoltaic power generation has a conversion efficiency of about 10%~20%. It includes crystalline model and
non-crystalline model. Crystalline model can be divided into single-crystal model and multi-crystalline model. About solar energy thermal electrical plants, trough solar power’s conversion efficiency can get to 15%, Spain will
build the largest trough thermal electrical plants of Europe. Furthermore, there also have other forms, as for Tower power etc.
