Problems solved by technology

However, this way of winding the water pipe, no matter how the water pipe is wound, the light-to-heat conversion efficiency is low, and it is difficult to quickly cool down the photovoltaic panel
When the cooling rate is lower than the heating rate caused by photoelectric conversion, the photoelectric conversion efficiency will continue to decrease eventually.

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only preferred embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] see Figure 1-Figure 3 As shown, a photoelectric photothermal integrated module includes a double-glass photovoltaic panel 1, a water tank body 2 and a component frame 3. The double-glass photovoltaic panel uses double-sided glass, and the back glass can conduct heat and can directly contact water for heating. For heat exchange, the shape of the water tank is generally ]-shaped, with extensions at the edges for fixed connections. The modul...

Abstract

The invention discloses a photoelectric and photo-thermal integrated module. The module includes a dual-glass photovoltaic panel, a water tank body and a component frame, wherein the component frame enables the periphery of the dual-glass photovoltaic panel and the periphery of the water tank body to be bonded fixedly, and there is a cavity which is formed by a gap for accommodating water betweenthe dual-glass photovoltaic panel and the water tank body. The water tank body is provided with an exhaust port, a water inlet and a water outlet. The module can increase the power generation capacityof a conventional photovoltaic module by 2-5% through an experimental test, and the temperature of the back surface of the dual-glass photovoltaic panel can be reduced by 15-25 DEG C, and the hot water temperature can be up to 30-45 DEG C, which achieves both purposes, and remarkably improves the utilization rate of photovoltaic power generation.

Description

technical field [0001] The invention relates to the field of solar photoelectricity and heat, in particular to a photoelectricity, light and heat integrated component. Background technique [0002] At present, there are two forms of solar energy utilization: one is to convert solar energy into electrical energy, which is generally called photovoltaic; the other is to convert solar energy into heat energy, which is generally called photothermal. As we all know, solar cell components will generate parasitic heat energy when converting solar energy into electrical energy, and the parasitic heat energy will increase the temperature of the components and reduce the photoelectric conversion efficiency. Generally, when the temperature exceeds 50°C, the photoelectric conversion efficiency will decrease. Usually, the glass surface temperature of photovoltaic modules is as high as 60-70°C. For solar photovoltaic power generation systems, the higher the temperature, the lower the conv...
