Description

Solar photovoltaic module and installation method thereof

Technical field

The invention relates to the field of solar energy, and in particular to a solar photovoltaic module and a mounting method thereof.

Background technique

With the rise of energy prices, the development and utilization of new energy has become a major issue in the field of energy research today. Because solar energy has the advantages of no pollution, no regional restrictions, and inexhaustible, research on solar power has become the main direction for the development and utilization of new energy. The use of solar cells to generate electricity is one of the main ways people use solar energy today. Solar energy needs to occupy a large number of land and other sites. Therefore, the combination of solar modules and roof tiles is common, but the current roof tile components are designed to be costly. Short board, and did not get a lot of application promotion.

If the roof tile PV module wants to directly replace the roof surface structure, it needs to be waterproof to meet the basic outdoor wind and snow natural conditions, and also to meet the sustainable power generation capacity. Actually, the current PV module roof is not ideal in structural sealing, and it cannot be applied to occasions requiring strict watertightness, but only suitable for breeding/planting/livestock, etc., and also faces the anti-crack failure of component installation and later maintenance. Risk, the common anti-cracking ability of the process components of the backplane assembly is weak, the risk of hot spot after cracking is intensified, and the risk of failure is further expanded; in the design of conventional small roof tile components, it is also facing difficulties in installation, how to Quick installation and convenient post-maintenance are also challenges.

The main crystalline silicon of the conventional solar cell includes polycrystalline/monocrystalline silicon cell components, but the conventional cell component has the problem of poor anti-cracking ability after packaging due to the characteristics of crystalline silicon brittleness, which easily leads to subsequent hidden crack current. It can not be collected, and hot spots appear in the current concentration, local high current and high temperature, etc., which poses a serious failure risk to the packaging materials of the components. In recent years, the market has gradually developed and applied double glass, but most of the design of double glass is borderless, and the double-frameless glass has no protection around, which makes the edge easy to touch, which causes the explosion to fail and the installation is difficult. Completely overcome in the anti-hidden crack, can achieve no cracks. A large number of conventional frames are developed every month on the market because the frame is the most expensive material in addition to the battery, and the cost factor causes the market to choose a double-glass application without a frame. However, the cracked short board of the single glass component, the double glass is easy to explode and the installation is difficult, these are not the best product applications.

In addition, in the current application of frameless double glass components, there is also the existence of internal stresses around the internal stress caused by the lamination heating process of the current components. The long-term application of double-glass components has edge-lifting on all four sides. potential risks. With long-term outdoor applications, external moisture still has the opportunity to invade the interior. In particular, the application of water-based double-glass components faces the risk of water vapor penetrating the edge. This is the surface oxidation of the cell and the continuous high performance of the cell. Challenges also pose risks to long-term quality commitments.

The current design of the conventional components corresponds to the main clamping block and the rear screw fixing mode. The rear screw fixing is relatively strong but the operation is inconvenient. When the front pressing block is installed in the typhoon area, many components are actually encountered because of the pressure. When the block is loose, the component string matrix is completely loose, and the component flies out and is damaged.

For the current double-sided battery power generation components, including N-type double-sided and heterojunction components, the current main use of double-sided double-glass structure, in the installation method also involves how to avoid the back cover, and can meet the normal load machinery Performance, the conventional briquetting installation method is not high in bearing capacity against wind pressure and snow pressure. There is insufficient support surface at the edge of the clamp, and there is a risk of back occlusion.

The first groove 110 and the second groove 210 are respectively used for accommodating side edges of two adjacent laminates 500, and the outer edge of the cover plate 120 covers the second frame 200. Part of the upper surface (Figure 2) or all of the upper surface (not shown) eliminates the risk of rain.

In order to facilitate the quick connection of the upper and lower laminates 500, the cover 120 is provided with a latching portion 121. Referring to FIG. 3, the second frame 200 is further provided with the latching portion 121. The third recess 220, the first bezel 100 and the second bezel 200 are engaged with the third recess 220 by the engaging portion 121, that is, the engaging portion 121 of the first bezel 100 is embedded in the second recess 220.
