Problems solved by technology

This photovoltaic tile product has many deficiencies, such as the direct connection between the tile and the battery, which makes the temperature too high under working conditions and the power generation is low; at the same time, when the heat is dissipated through the heat dissipation holes on the ceramic base, the waterproof performance cannot be guaranteed. And the joints will be exposed to direct sunlight and accelerate aging

Embodiment 1

[0032] like figure 1 and figure 2 As shown, the present embodiment is a photovoltaic module 6 , which includes a pressed glass plate 61 , battery sheets 62 and a back plate 63 , and a plurality of cooling ribs 631 are arranged on the back plate 63 . In this embodiment, the backboard 63 is an aluminum backboard, and the glass plate 61 is a coated tempered glass plate. The coated toughened glass plate on the upper surface ensures the strength of the upper surface of the photovoltaic module 6 of this embodiment, improves its compression resistance, fire resistance and anti-hail ability, and the aluminum back plate replaces the existing conventional glass or polymer material back plate, which plays a role Reduce material costs, improve thermal conductivity and heat dissipation performance.

[0033] In this embodiment, the heat dissipation fins 631 are arranged on the back plate 63 to dissipate heat. The heat dissipation fins 631 increase the contact area between the photovoltai...

Embodiment 2

[0036] like Figure 3 ~ Figure 5 As shown, this embodiment is a photovoltaic tile for installing the above-mentioned photovoltaic module 6, including a tile base 3, and an upper rib 31, a lower rib 32, and an upper rib 32 are arranged on the tile base 3. The positioning groove 33 between the rib 31 and the lower rib 32, the upper rib 31 and the lower rib 32 are arranged in parallel, the horizontal support part 633 of the support member 632 is fixedly connected with the bottom of the positioning groove 33, and the photovoltaic module 6 Both ends are abutted between the upper rib 31 and the lower rib 32 . In this embodiment, the bottom of the photovoltaic module 6 is fixedly connected to the bottom of the positioning groove 33 through the horizontal support part 633, and the upper and lower ends of the photovoltaic module 6 are abutted between the upper rib 31 and the lower rib 32 to realize the alignment of the photovoltaic module 6. The fixing of the upper and lower positions...

Embodiment 3

[0040] like Image 6 and Figure 7 As shown, this embodiment is a photovoltaic module system on the roof of a building, including a water-slip strip 1 arranged on the roof of the building, a tile strip 2, a photovoltaic tile matched with the tile strip 2, and a photovoltaic module arranged on the photovoltaic tile. The photovoltaic tiles in this embodiment are the photovoltaic tiles in Embodiment 2, and the photovoltaic modules are the photovoltaic modules in Embodiment 1.

[0041] In this embodiment, the power system is connected to the left and right through the junction box. Since the junction box is below the upper battery assembly, this embodiment ensures that it will not be too much affected by rainwater and ensures the safety of power supply. At the same time, the left and right photovoltaic tiles overlap each other to ensure the waterproof problem in the left and right directions, and the left and right tiles are on the same plane to form a transverse cavity to ensure...

Abstract

The invention discloses a photovoltaic assembly, a photovoltaic tile and a photovoltaic system of a building roof. The photovoltaic assembly comprises an integral glass plate, a battery slice layer and a back plate; a plurality of heat-dissipating ribs are arranged on the back plate. The photovoltaic tile comprises a tile substrate; an upper flange, a lower flange and a positioning groove formed between the upper flange and the lower flange are arranged on the tile substrate; the upper flange and the lower flange are arranged in parallel; the horizontal supporting portion of a supporting pieceis fixedly connected to the bottom of the positioning groove; and the two ends of the photovoltaic assembly lean against between the upper flange and the lower flange. The crystalline silicon batteryslice, tempered glass and the aluminum back plate are integrally arranged, and the photovoltaic aluminum back plate dissipates heat, so that the heat-dissipating efficiency is increased. An air flowing cavity is formed in the photovoltaic tile, so that the ventilating and heat-dissipating effect of the photovoltaic assembly is better than that of a common photovoltaic tile, the power generation efficiency of the photovoltaic assembly is increased, and meanwhile, the integral temperature of the roof is reduced, and the use rate of an air conditioner in summer is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a photovoltaic module, a photovoltaic tile and a building roof photovoltaic system. Background technique [0002] As a low-carbon renewable energy source, the solar energy industry is booming around the world, and the installations in various countries are increasing year by year. Due to its flexible installation and other characteristics, distributed photovoltaics have developed rapidly in recent years. In the current residential distributed system, it is often used to install solar panel brackets and solar panels on the existing roof for distributed power generation, which not only affects the aesthetics of the building, but also increases unnecessary resources such as brackets. waste. [0003] At the same time, there are BIPV tiles currently on the market, such as the patent document CN 201722851U which discloses a new type of photovoltaic tile that can effe...
