[0002] With the increase of the installed capacity of solar power generation in China, the number of waste solar power generation components will gradually increase over time. The vast majority of waste solar power generation components have not reached their service life. The most valuable battery chips in solar power generation components will be discarded in large quantities due to the gradually decreasing production cost and the limited profit space for recycling and reuse.

[0018] Embodiment

[0019] Please refer to Figure 1, in this embodiment, a combined heat and power photovoltaic panel based on waste solar power generation components is provided. The photovoltaic panel includes a profile frame 9 made of aluminum alloy. Inside the profile frame 9, from outside to inside, there are photovoltaic glass 1, a transparent adhesive layer 2, a solar cell module 3, a first backsheet 4, an inner adhesive layer 5, a heat collector 6, a thermal insulation layer 7, and a second backsheet 8 in sequence. The profile frame 9 made of aluminum alloy tightly combines the above-mentioned layers of structures to form a photovoltaic panel structure;

[0020] Among them, the photovoltaic glass 1, the transparent adhesive layer 2, the solar cell module 3, and the first backsheet 4 all adopt structural components in waste solar power generation components, achieving the reuse of waste solar power generation components;

[0021] Specifically, the photovoltaic glass 1 is tempered protective glass, with patterns printed on its inner side to increase aesthetics and recognition. At the same time, the transparent adhesive layer 2 has high light transmittance, thus avoiding the situation of blocking or hindering sunlight. The solar cell module 3 is the reuse of waste batteries, and the first backsheet 4 is the reuse of waste battery plates;

[0022] A photovoltaic panel junction box 10 is also installed inside the photovoltaic panel. A connecting wire is led out from the photovoltaic panel junction box 10 for electrical connection with the outside. At the same time, a heat collector inlet and outlet 11 is also provided on the heat collector 6;

[0023] The solar cell module 3 includes a monocrystalline silicon cell module, a polycrystalline silicon cell module, a cadmium telluride cell module, and a copper indium gallium selenide cell module;

[0024] The heat collector 6 includes a full-flow heat collector, a single-flow heat collector, a semi-flow heat collector, and a fin heat collector. The material of the heat collector 6 is made of stainless steel, copper, or aluminum alloy;

[0025] The materials of the thermal insulation layer 7 include vacuum insulation panels, aerogel thermal insulation materials, foamed polyurethane, extruded polystyrene boards, phenolic boards, graphite polystyrene boards, rubber and plastic thermal insulation materials, aerated concrete, etc., which can be selected according to needs.

[0026] The bonding of the waste structural components in the waste solar photovoltaic panel and the heat collector 6 uses a laminator. The solar power generation component is disassembled and moderately cleaned, and the heat collector 6 is bonded behind the first backsheet 4 to achieve tight compaction between the heat collector 6 and the first backsheet 4 of the waste photovoltaic panel, and they are bonded into one body.

[0027] During operation, sunlight passes through the photovoltaic glass 1 and the transparent adhesive layer 2 and irradiates on the solar cell module 3 to generate current. The solar energy converted into electrical energy is converted into heat energy, which is absorbed by the solar cell module 3, the inner adhesive layer 5, and the first backsheet 4. The heat collector 6 absorbs the heat of the above-mentioned structures and takes it away through internal water circulation.

[0028] The photovoltaic panel of the present utility model realizes the integration of solar photovoltaic / thermal (PVT). While the solar power generation module continues to generate electricity, it also realizes the collection and utilization of solar heat. This method can maximize the reuse of waste solar power generation modules;

[0029] Furthermore, it can also be widely applied to various industrial and civil buildings, combining photovoltaic power generation and solar heat to form the achievement of cogeneration of photoelectricity, increasing the collection conversion rate of unit light energy to more than 55%, and the hot water temperature in the collector 6 can reach more than 60 degrees Celsius.
