Problems solved by technology

During the working process of photovoltaic panels, only 10%-20% of the solar energy is converted into electrical energy, and the rest of the solar energy is dissipated in the form of heat, which makes the surface temperature of photovoltaic panels extremely high when exposed to the sun. The power generation efficiency of photovoltaic panels will be significantly reduced, and long-term heating will also affect their service life

Abstract

The invention provides a heat-dissipation photovoltaic panel system. The heat-dissipation photovoltaic panel system comprises a panel frame, wherein the panel frame inclines, a photovoltaic panel is arranged in the panel frame, the panel frame is supported by a photovoltaic support, the photovoltaic support comprises a base, the base is fixedly arranged on a bottom surface or a building surface, awater storage cavity is formed in the base, a front support part and a rear support part are respectively arranged at a front end and a rear end of the base in an upward and extension way, a front part and a rear part of the panel frame are respectively supported by the front support part and the rear support part, a water passage is arranged in the front support part and communicates with the water storage cavity, a one-way valve is arranged in the water passage, water slipping from a surface of a glass cover plate on the photovoltaic panel only can flow into the water passage, passes through the one-way valve and then enters the water storage cavity, the panel frame comprises a metal frame, and a bottom surface of the panel frame is connected to a heat exchanger in the water storage cavity via a heat conduction pipe. By the heat-dissipation photovoltaic panel system, automatic cooling can be achieved when a temperature of the photovoltaic panel is relatively high, so that the powergeneration efficiency is improved, and the service lifetime of the photovoltaic panel is prolonged.

Description

technical field [0001] The invention relates to the field of energy equipment, in particular, to a photovoltaic panel system. Background technique [0002] As a clean energy device, the photovoltaic panel system has broad application prospects and is currently popular. During the working process of photovoltaic panels, only 10%-20% of the solar energy is converted into electrical energy, and the rest of the solar energy is dissipated in the form of heat, which makes the surface temperature of photovoltaic panels extremely high when exposed to the sun. The power generation efficiency of photovoltaic panels will be significantly reduced, and long-term heating will also affect their service life. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a heat dissipation photovoltaic panel system, which can automatically cool down when the temperature of the photovoltaic panel is high, so as to improve the power gene...
