Problems solved by technology

[0004] The purpose of the present invention is to provide an integrated photovoltaic module production process to solve the problem that during the use of an existing photovoltaic module proposed in the above-mentioned background technology, since the existing photovoltaic module generally consists of a front glass, a back plate or a back glass It is obtained by encapsulating solar cells with EVA, which is not integrated with the external protection device, and the heat dissipation effect is poor, so there are problems that the light cannot be accurately irradiated on the top of the photovoltaic panel and the temperature rise will cause the output power of the solar cell to drop.

Abstract

The invention discloses an integrated photovoltaic module production process comprising an outer protection frame, a photovoltaic panel and transparent tempered glass; a heat insulation layer is fixedly installed on the inner side of the outer protection frame, a heat absorption box is fixedly installed at the bottom of an inner cavity of the outer protection frame, and a heat conduction block isfixedly installed in the top wall of the heat absorption box; a plurality of condensing convex lenses are fixedly installed at the bottom of the transparent tempered glass, the photovoltaic panel comprises a back plate, a heat conduction plate is fixedly installed in the back plate, a limiting frame is fixedly installed at the top of the back plate, and a lower EVA film is bonded to the interior of the limiting frame. A plurality of condensing convex lenses are mounted at the bottom of transparent tempered glass and can be arranged to form a condensing layer, so that no matter which directionsolar rays irradiate the condensing convex lenses, the condensing convex lenses can well refract and condense the rays, the rays can accurately irradiate the top of a photovoltaic panel. And the orientation of the photovoltaic panel does not need to be changed frequently for tracking the sun, so that the cost performance of the whole assembly is improved, and popularization and application of thephotovoltaic assembly are facilitated.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic components, and in particular relates to an integrated photovoltaic component production process. Background technique [0002] A single solar cell cannot be directly used as a power source, and multiple single solar cells must be combined to form a photovoltaic module before it can be put into use. Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. [0003] Existing photovoltaic modules are generally obtained by encapsulating solar cells with front glass, back glass or back glass and EVA. For example, a photovoltaic module production process disclosed in Chinese invention patent No. CN103094416B, although plasma treatment technology is used , to solve the weak point of the low bonding strength between the weather-resistant layer of the backplane and the EVA film in the tradi...
