Sun-tracking photovoltaic panel

Abstract

The invention discloses a sun-tracking photovoltaic panel. The sun-tracking photovoltaic panel comprises a mounting plate and a bottom plate which are arranged in parallel along a longitudinal direction, and further comprises a photovoltaic panel embedded in the upper end of the mounting plate, wherein the mounting plate and the bottom plate are circular; a plurality of heat collection tracking devices are rotationally and symmetrically arranged at the upper end of the mounting plate and on the outer side of the photovoltaic panel; the heat collection tracking devices comprise circular heat collection grooves which are symmetrically formed in the upper end of the mounting plate relative to the bisector of the photovoltaic panel; the inner bottom walls of the heat collecting grooves are fixedly connected with power generation blocks; focusing mirrors are fixedly connected to the inner walls of the heat collecting grooves, and the focuses of the focusing mirror are located on the power generation blocks; the mounting plate is connected with a supporting rod through a first universal mechanism; the lower end of the supporting rod is vertically and fixedly connected to the upper end ofa bottom plate; a barrel is fixedly connected to the upper end of the bottom plate; and the barrel, the heat collecting grooves and the supporting rod are located on the same plane. The sun-trackingphotovoltaic panel has the advantages that the photovoltaic panel is always kept at the optimal orientation for receiving solar rays, so the solar energy receiving efficiency of the photovoltaic panelis improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic panels, in particular to a solar tracking photovoltaic panel. Background technique [0002] The current power generation method is mainly thermal power generation, and thermal power generation uses coal, which is a non-renewable resource, and produces more harmful gases due to sufficient or insufficient combustion during the power generation process, polluting the atmosphere and easily causing the greenhouse effect. With the gradual improvement of environmental protection awareness, photovoltaic power generation, hydropower generation, wind power generation and other power generation methods that use renewable resources and do not generate harmful gases are also more and more widely used. [0003] Among them, photovoltaic panels are one of the important components of photovoltaic power generation. The main factor affecting the power generation efficiency of photovoltaic panels is the intensit...

Problems solved by technology

[0003] Among them, photovoltaic panels are one of the important components of photovoltaic power generation. The main factor affecting the power generation efficiency of photovoltaic panels is the intensity of sunlight received. As the earth undergoes self-propagation with time in a day, the angle of sunlight shining on photovoltaic panels is also constantly changing. However, the structure of the existing photovoltaic panel is fixed, and it is often set at a fixed angle of inclination. It is impossible to change it according to the angle of sunlight, and the conversion efficiency of solar energy is also low.
