摘要：Solar energy is an inexhaustible supply of clean energy, and it is one of the most common natural resources of solar energy. To provide a more economical, environmentally form of supplying power for the far away grid and some villa. This paper presents the design of household solar power system. According to the local weather conditions, environment and the demand of the household electricity load. This paper presents how to select the devices according the actual condition. It includes how to choose the model of the inverter, how to determine the battery capacity, how to determine the solar panel module and the construction requirements. Finally, this paper make an economic assessment for this power generation. This economic assessment is about the PR, NPV and the discounted payback period.
