Nowadays more and more distributed photovoltaic is connected to distribution grid. Under the condition, as an effective method of improving grid stability and decreasing electricity cost, the photovoltaic and energy storage system has become an important trend of new energy application. Application of the user-side photovoltaic and energy storage system in the developed countries as Europe, United States and Japan was studied. On the base of the analysis, the important developing condition and technology roadmap of the user-side photovoltaic and energy storage system abroad was summarized. Secondly, some typical domestic photovoltaic and energy storage projects in the business market, industrial park and residential area were introduced. And the development problems of the domestic photovoltaic and energy storage projects were analysed. Finally, according to the analysis of the application experience abroad and the situation of the rapid development of the electric vehicle charge at home, the development suggestions are put forward, which can be used for reference for the healthy development of domestic user side optical storage projects.
