PV PV applications are based on the principles of solar photovoltaic effect electric batteries, solar cells utilizing solar energy directly into electricity. Whether used independently or grid, photovoltaic power generation system consists of solar panels (components), controller and inverter three major components, which mainly consists of electronic components, does not involve mechanical parts, so, photovoltaic power generation equipment extremely refined, stable and reliable long life, easy installation and maintenance. Theoretically PV, photovoltaic technology can be used for any occasion need power, from the spacecraft down to the household power photovoltaic inverter, large megawatt photovoltaic power plant cost, small toys, photovoltaic power can not ubiquitous. PV array system can be installed in the difference between the level of the best angle roof glazing facade and roof-mounted installation for maximum power output, and using conventional crystalline silicon photovoltaic modules, reducing the investment cost components, often economy want good effect, but this installation aesthetics in general. Wuhan is the best angle of about 30 degrees to the south in the Northern Hemisphere tilted roof, southeast, southwest, east or due west of the roof can be used to install a photovoltaic array on the roof of the south to be able to follow the optimum tilt angle or installed close to the optimum angle. Photovoltaic power plants, solar power, day-giant technology provided by the Wuhan days Hui Technology Co., Ltd. giant. Wuhan Tian Hui Ju Technology Co., Ltd. (www.thjnkj.com) (www.thjnkj.com) strong, credible, in Wuhan, Hubei and other energy-saving equipment industry has accumulated a large number of loyal customers.
