Abstract
Thesis mainly completed the 5 kw of distributed grid pv system design work, lists the specific need. (1) first of all, the photovoltaic industry are described briefly the background and development situation at home and abroad. Due to the growing energy crisis, searching for green energy has become the only way to solve the problem of energy crisis. In such an environment, solar energy will get great development. (2) and to investigate the feasibility of the design report, a survey of geography, climate, electricity and so on various aspects of factors, and this paper expounds the principle of grid. (3) and then design a 5 kw distributed grid photovoltaic power generation system, successfully connected to the grid. The sun elevation Angle and azimuth Angle is studied on the effect of shadows and hot spot effect, and all kinds of protection measures. Was elected the building site, design the building plan. (4) finally, the system of main equipment were selected, and lists out, finally through the PVsyst simulation runs out of the design results.
Keywords：Photovoltaic status The feasibility investigation Hot spot effect
