光伏发电不受资源和制造材料的限制，是未来最主要的替代能源。我国目前是世界光伏电池的第一大生产国，制造成本近年来大幅度下降，预计5~10年内可以达到“平价上网”，做到与常规电力相竞争。光伏发电在国内的规模化推广有利于实现我国的减排目标和能源的可持续发展，但需要在政策、资金和电网接入等方面做出更大努力。

PV is never limited by resources and production materials and is the main alternative energy sources in the future. China is now the largest producer of PV modules in the world and has made remarkable cost reduction in recent years.It is expected that PV will reach "grid-parity"  within 5~10 years and become market competitive with conventional electricity.Large scale utilization of PV domestically will give great help to realize the target of GHG reduction and energy sustainable development in China.We still need great efforts in incentive policies, financing and grid-connection.
