Production method of 2.5 mm photovoltaic module ultrathin tempered coated glass

Abstract

The invention discloses a production method of 2.5 mm photovoltaic module ultrathin tempered coated glass. Deep processing is carried out on a 2.5-mm ultrathin solar photovoltaic glass sheet with extremely low iron content, and an automatic deep processing flow production line is planned and assembled through the advanced production process. A specially-made toughening furnace is used for being matched with a corresponding sheet feeding machine, an edge grinding machine, a coating machine, a glass cleaning machine, a sheet discharging machine, a driller, a driller cleaning machine, a power supply and distribution system and a pure water circulating system to carry out deep processing on 2.5-mm ultrathin solar photovoltaic glass, and the 2.5 mm ultrathin tempered coated photovoltaic module glass meeting the requirement of the market is manufactured.

Description

technical field [0001] The invention is applied to photovoltaic solar cell components. The toughened coated glass is an important link in the industrial chain. The glass with a thickness of 3.2 mm and 4 mm is most widely used in photovoltaic components, and its light transmittance is about 93.5%. Realizing the toughening application of 2.5mm photovoltaic module ultra-thin coated glass is to effectively improve the penetration of more light through photovoltaic glass to ensure optical performance indicators such as photovoltaic glass, which plays a key role in improving the power generation of the entire solar cell module. effect. Background technique [0002] The existing production methods for photovoltaic tempered glass cannot meet the tempering technical requirements for 2.5mm ultra-thin photovoltaic glass, and cannot achieve full tempering of 2.5mm ultra-thin photovoltaic glass. [0003] Disadvantages of the existing technology, 1) The operating cost of the deep process...

Problems solved by technology

[0002] The production methods used in the existing photovoltaic tempered glass cannot meet the tempering technical requirements for 2.5mm ultra-thin photovoltaic glass, and cannot realize the full tempering of 2.5mm ultra-thin photovoltaic glass

[0003] Disadvantages of the existing technology, 1) The operating cost of the deep processing line of photovoltaic coated glass is high, the main technical indicators of the present invention are product yield ≥ 97%, product transmittance ≥ 94%, product energy consumption: power consumption ≤ 3.0kwh / ㎡, water Consumption ≤0.014T / ㎡; 2) When tempering furnace equipment produces ultra-thin photovoltaic glass with a thickness of less than 2.8mm, problems such as wave degree, number of particles and optical deformation of the glass surface cannot meet the requirements for the use of photovoltaic solar cell modules
