Under the background of this kind of fossil energy supply has become increasingly tense, it is necessary to large-scale use and development of renewable energy. Solar energy as an inexhaustible, clean resources become a hotspot of research on human development, and has achieved significant effect. As an ideal energy, distributed generation photovoltaic generating system solves the independent model, the difficulty of some local electricity, has significantly improved peoples living standard. This article discusses the development status and application prospect of photovoltaic power generation system, the independent model photovoltaic power generation system research and design. In this paper, based on the energy storage system of the independent model of photovoltaic power generation system as the research object, this paper expounds the independent model, the basic principle of the photovoltaic power generation and its development trend. For photovoltaic system was analyzed, and the Maximum power tracking (MPPT) control method, through to the lawn lamp design, further analysis of photovoltaic power generation systems. Capacity of the photovoltaic system design calculation is analyzed, including photovoltaic battery board power calculation, battery capacity, calculation of charge and discharge. Through the calculation of system capacity and to consider economic factors, selected is suitable for the various system components. In this paper, through the study of solar energy lawn lamp design, realization of photovoltaic energy storage and its charge and discharge, further sure photovoltaic energy strategy the important position in modern society.
