Abstract :
In this paper, main different grid-connected photovoltaic (PV) standard systems, included IEC system, western country system, American system and China system have been summarized, analyzed and compared. Based on comparison between different standard systems, relative merits, existing difference, and reasons of difference have been analyzed in gird-connected PV standard system. Furthermore, combined with relevant PV generation policy and technology developing status, the prospect analyze has been proposed for future grid-connected PV standard system development in each system.
