Description

A solar photovoltaic photothermal integrated component

technical field

The utility model relates to a solar photovoltaic photothermal integrated component, specifically refers to improving the traditional packaging structure of the component through the application of new component packaging materials, realizing the comprehensive application of power generation and heat generation of the component, and promoting the application of solar energy. the

Background technique

Solar energy is the most abundant renewable energy resource, with unique advantages and huge potential for development and utilization. As a renewable and environmentally friendly energy source, solar cells have attracted more and more attention. In recent years, the application of solar energy has developed from traditional photovoltaic power plants to rooftop power plants and distributed applications. Therefore, higher requirements have been put forward for the comprehensive application of solar energy.

The structure of a traditional component is:

Aluminum frame + 3.2 mm low-iron ultra-clear tempered glass + EVA + battery sheet + EVA + backplane structure, due to the application of aluminum frame increases the overall weight and thickness of the module, it is necessary to lay additional installation brackets under the module during installation. It is not conducive to the combination and integration with the building, and affects the overall aesthetics of the building.

On the other hand, with the current overcapacity in the photovoltaic industry and the gradual decline in module prices, there is little room for further cost reduction of the main materials of modules. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a solar photovoltaic photothermal integrated assembly to achieve the comprehensive application of photovoltaic and photothermal, and the purpose of energy saving and environmental protection.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a solar photovoltaic photothermal integrated module, including a plurality of battery strings arranged side by side, the battery strings include several battery slices connected in series, and the plurality of side-by-side The fronts of the cells of the set battery strings are all fixed on a piece of low-iron ultra-white tempered glass by EVA, and the backs of the cells of the plurality of battery strings arranged side by side are all laid with a piece of semi-tempered glass by EVA. The current lead-out wire of the battery sheet is led out to the junction box through the gap between the low-iron ultra-white tempered glass and the semi-tempered glass, and the junction box is fixed on the low-iron ultra-white tempered glass or the semi-tempered glass; The semi-tempered glass is fixed on the water tank, and the water tank is provided with a water inlet and a water outlet.

As a preferred solution, the battery strings are divided into several groups, each group has two battery strings, and the battery strings between adjacent groups are connected by busbars, and the current lead-out wires of the battery slices in each group of battery strings pass through the low-iron supercharger. The gap between the white tempered glass and semi-tempered glass leads to a junction box.

Compared with the prior art, the utility model has the beneficial effects as follows: the utility model replaces the back panel of the traditional assembly with semi-tempered glass, and designs a thin water tank under the back panel glass, and utilizes the recovered solar energy converted into The heat is recycled and used, and at the same time it can cool the temperature of the solar panel and improve the power generation efficiency of the module; the front and back of the battery are fixed with glass, which ensures that the module has a certain mechanical strength and bearing capacity, so the aluminum frame can no longer be used The structure reduces the thickness of the component from the surface, and also reduces the cost of the component. On the other hand, because the new photovoltaic module is designed without a frame, the thickness of the whole module is thinner than that of the traditional module, which is convenient for the installation of photovoltaic and building integration, and ensures that the overall building is more beautiful.
