Solar energy as a new type of renewable energy, clean and inexhaustible,inexhaustible, is an important part of the green energy around the world. The photovoltaicpower generation is an important way for solar applications, at home and abroad in recentyears, more and more attention to the development and utilization of solar.The research of photovoltaic power generation is the face of the user, the photovoltaicpower generation is converted into alternating current for household use. This stage homesolar power system is not popular mainly due to two points: First, the cost of the solarpower system is too high; conversion of solar energy into electrical energy efficiency is toolow. In this thesis, a study on these two points, try to make a home solar power systemtends to improve.The main contents include:First, This paper introduces the research status ofphotovoltaic power generation, to analyze the nature and working principle of solar panels.An improved domestic solar photovoltaic power generation system, through the state’spolicy to support the excess capacity of solar power into the grid by grid companies toprovide electricity devices in the system at the same time to remove the use of batteries.Analyzing the maximum power point tracking technology, in order to improve the energyconversion efficiency of this thesis is based on the perturbation and observation method anew MPPT detection method is based on the four corners of the module detects a delaystart closed disturbance observer method. Photovoltaic power generation and network keytechnologies, the Buck circuit comparative analysis, Boost circuit, Buck-Boost circuitworking principle, advantages and disadvantages, and ultimately determine this thesis, thestudy of photovoltaic power generation system should be used Boost circuit. Be introducedon the island effect analysis.Finally, the full-text summary, further research raised someprospects.
