Solar photovoltaic system

Abstract

Disclosed is a solar photovoltaic system. The solar photovoltaic system is characterized in that a solar photovoltaic cell is mounted on a roof by support legs, an air flow channel is arranged between the roof and the solar photovoltaic cell, an induced draft fan is mounted in the air flow channel, and a wind cap is arranged at the upper end of the solar photovoltaic cell. The solar photovoltaic system has the advantages that the support legs are arranged on the lower side of the solar photovoltaic cell, so that a sandwich layer can be formed between the solar photovoltaic cell and the roof and is used as the air flow channel, heat is dissipated, the generating efficiency is improved, hot air can be quickly exhausted by the aid of the induced draft fan, and heat of the hot air can be quickly dissipated by the aid of the induced draft fan; the photovoltaic cell is reasonable in mounting position and structural design and is unaffected by the illumination time and the illumination intensity; safety factors such as water resistance of the roof, a structural supporting property and wind resistance are sufficiently considered; redundant electric power can be connected into a power grid, so that the power transmission cost and the power distribution cost are lowered, and the reliability of a power supply facility is improved; and the photovoltaic cell is harmonious with surrounding buildings and is low in operating cost, little in maintenance and long in service life.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar photovoltaic system integrated with a building. Background technique [0002] At present, solar photovoltaic technology and photovoltaic industry are developing rapidly. Photovoltaic power generation has gradually shifted from solving power consumption and special power consumption in remote areas to grid-connected power generation and building-integrated power supply. The application of solar photovoltaic systems and building integration is mainly through Solar photovoltaic panels convert light energy into electrical energy and store it in batteries, which can be used for lighting in stairwells, lighting in emergency lights, and control of intelligent systems. Solar photovoltaic roof power generation system has become the most important photovoltaic application in the world market because of its easy installation, stable power and long life. However, the output powe...
