Problems solved by technology

[0002] Solar panels are relatively conventional as solar power generation devices, but most of the current solar panels are small and medium-sized. As decentralized power generation devices, the efficiency of power use after power generation is not very high
However, for large or super-large solar panels that are not used very much, after using them for a period of time or after rain, snow, or windy weather, the surface is not cleaned very well, which greatly reduces the utilization rate of solar energy. It will also affect the durability of solar panels

Embodiment 1

[0021] An ultra-large solar power generation device, including a solar panel and a matching cleaning device.

[0022] The cleaning device includes a plurality of stroke water spray scrapers arranged side by side, a plurality of fans arranged side by side, an induction device and a control device.

[0023] The stroke water spray scraper is used to clean the dirt on the front glass surface of the solar panel, including a rubber scraper in contact with the front glass surface of the solar panel, an upper fixed shell and a telescopic arm (extended forward along a straight line) , so that the rubber squeegee advances, and can be retracted in a straight line after reaching the farthest, so that the rubber squeegee scrapes on the upper surface of the glass, so as to achieve the purpose of cleaning the glass surface), the upper fixed shell is close to the rubber A water mist nozzle is set on one side of the scraper (if the control device issues a water spray command, it will spray wat...

Embodiment 2

[0029] The mass percent composition of the front layer glass includes: Ge: 18%, Sb: 19%, Te: 5%, Ce: 0.3%, and the balance is Se and unavoidable impurities.

[0030] The front layer of glass is strengthened through the following steps after molding:

[0031] (1) Place the formed front glass into a cryogenic box to cool to -66°C, keep the temperature for 22 minutes, and then slowly return to room temperature after going out of the cryogenic box.

[0032] (2) Put the front glass treated in step (1) into a resistance furnace, heat it to 260°C with the furnace, keep the temperature for 82 minutes, and then spray water to cool it to room temperature.

[0033] (3) Put the front glass after the treatment in step (2) into the electric resistance furnace again, heat it up to 130°C with the furnace, keep the temperature for 25 minutes, and then cool it down to room temperature with the furnace.

Embodiment 3

[0035] The mass percentage composition of the front layer glass includes: Ge: 19%, Sb: 21%, Te: 3%, Ce: 0.51%, and the balance is Se and unavoidable impurities.

[0036] The front layer of glass is strengthened through the following steps after molding:

[0037] (1) Place the formed front glass into a cryogenic box to cool to -58°C, keep the temperature for 22 minutes, and then slowly return to room temperature after going out of the cryogenic box.

[0038] (2) Put the front glass treated in step (1) into a resistance furnace, heat it to 238°C with the furnace, keep the temperature for 88 minutes, and then spray water to cool it to room temperature.

[0039] (3) Put the front glass treated in step (2) into the electric resistance furnace again, heat it up to 150°C with the furnace, keep the temperature for 26 minutes, and then cool it down to room temperature with the furnace.

Abstract

The invention relates to an ultra-large solar power generation device, which mainly includes a solar panel and a matching cleaning device. By reasonably setting the component content of the front glass of the solar panel, the light transmittance of the whole, especially the infrared light, is improved, so that the solar energy The power generation efficiency of the panels has been improved; at the same time, the reasonable allocation of supporting cleaning devices has greatly improved the durability of super-large solar panels.

Description

technical field [0001] The invention belongs to the field of clean energy, in particular to the field of solar power generation, in particular to a large-scale or super-large solar power generation device. Background technique [0002] Solar panels are relatively conventional as solar power generation devices, but most of the current solar panels are small and medium-sized. As decentralized power generation devices, the efficiency of power use after power generation is not very high. However, for large or super-large solar panels that are not used very much, after using them for a period of time or after rain, snow, or windy weather, the surface is not cleaned very well, which greatly reduces the utilization rate of solar energy. It will also affect the durability of solar panels. Contents of the invention [0003] The object of the present invention is to propose a super-large solar power generation device. [0004] Specifically, it is achieved through the following tec...
