Photovoltaic and photothermic integration solar thermal collector

Abstract

The invention discloses a photovoltaic and photothermic integration solar thermal collector. The photovoltaic and photothermic integration solar thermal collector comprise a thermal collector frame body which is divided into a center area and a periphery area which surrounds the center area, wherein the center area is concaved downward and forms a groove body, and a first EVA gum layer, a solar cell panel, a second EVA gum layer and a solar energy backboard are sequentially bonded on the periphery area from top to bottom. The photovoltaic and photothermic integration solar thermal collector further comprises a solar heat absorption plate which is arranged in the groove body of the center area and a glass cover plate which covers the outer surface of the thermal collector frame body, wherein a horizontal plane where the solar heat absorption plate is installed is lower than a horizontal plane where the periphery area is located, and a cavity is formed between the solar heat absorption plate located in the center area and the glass cover plate. The photovoltaic and photothermic integration solar thermal collector can combine a solar thermal collector and a solar photovoltaic module together, and light catching areas of the solar thermal collector and the solar photovoltaic module can not influence each other.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a photovoltaic, photothermal and integrated solar heat collector. Background technique [0002] At present, although there are photothermal photoelectric conversion devices such as solar collectors and photovoltaic modules in solar energy applications, when solar thermal photoelectric comprehensive utilization occasions include both photothermal utilization and photoelectric applications, solar collectors and photovoltaic modules need to be considered. For the installation of photovoltaic modules, the separate installation of the two not only increases the design workload, but also costs a lot, and also occupies a large installation area. In the integrated photovoltaic solar thermal collector, the solar panel is placed under the transparent cover plate, which can generate electricity and hot water at the same time. However, the solar panel and the heat-absorbing plate cor...

AI Technical Summary

Problems solved by technology

However, the solar panel and the heat-absorbing plate core are placed under the transparent cover, so that the solar panel and the heat-absorbing plate core are in the same greenhouse. In the temperature range, because the panel temperature of the solar panel affects the efficiency of the panel, the efficiency of the solar panel decreases if the panel temperature is too high

At the same time, solar panels and heat-absorbing plate cores placed under the transparent cover also occupy part of the solar collector's lighting area, the amount of hot water provided by the solar collector is affected, and the overall efficiency of the entire collector is reduced.
