Description

Technical Field

[0001] The utility model relates to the field of frames and double-glass photovoltaic modules, specifically to a photovoltaic module frame and a double-glass photovoltaic module. Background Art

[0002] Double-glass photovoltaic modules are a special type of photovoltaic modules, and their structure is different from that of traditional photovoltaic modules. Traditional photovoltaic modules are usually composed of a piece of glass, solar cells, EVA film, backplane and aluminum frame, while double-glass photovoltaic modules are composed of two pieces of glass and solar cells as a composite layer, and the cells are connected in series and parallel by wires to the lead ends to form a photovoltaic cell module. The characteristic of this module is its double-sided power generation performance, that is, light can be irradiated to the cells from the front and back of the module at the same time, thereby generating current and improving power generation efficiency.

[0003] The advantages of double-glass photovoltaic modules include higher power generation efficiency, longer service life, better weather resistance, lower attenuation rate, higher light transmittance, better self-cleaning performance, etc. In addition, double-glass photovoltaic modules also have better fire resistance and wind pressure resistance, and can adapt to more severe environmental conditions. However, the cost of double-glass photovoltaic modules is relatively high, mainly due to its high production process and material costs.

[0004] The existing photovoltaic module frame is wrapped around the outside of the double-glass photovoltaic module. The frame is a combined structure and is fixed by fixing bolts to firmly fix the double-glass photovoltaic module therein. However, since the fixing bolts are always exposed to the air, the fixing bolts are usually made of metal materials such as steel or stainless steel. The bolts are easily affected by corrosion when exposed to the natural environment for a long time, especially in harsh environments such as humidity and salt spray. Corrosion will cause the cross-sectional area of ​​the bolts to decrease, thereby reducing their bearing capacity and making them prone to breakage. Therefore, a photovoltaic module frame and a double-glass photovoltaic module are proposed. Utility Model Content
