In recent years, the solar power generation industry has developed rapidly. Solar energy is a clean energy source, and the process of converting solar energy into electrical energy will not cause pollution to the environment. The demand for photovoltaic module products has doubled, of which the aluminum solar panel frame
is also a part of the module. Aluminum solar panel frame is made by extruding aluminum profiles, and then surface treatment and deep processing. Aluminum solar panel frame requirements are higher than ordinary aluminum alloy profiles, which cannot be produced by ordinary aluminum profile manufacturers. Let's analyze where the specific height is.
1. Tolerance of shape and position, because the aluminum solar panel frame is connected by a corner code, the corner code is fortified in the cavity. If the cavity is large, the corner code will be loose and fall off. If the cavity is small, the angle code will be difficult to insert. The large tolerance also affects the later punching and riveting processing.
2. Surface quality. The surface quality includes color brightness, uniformity, sandblasting uniformity, surface bubbles, peeling, scratches, black lines, bright lines, etc. Any item that does not meet the requirements is unqualified.
3. Corrosion resistance, the corrosion resistance of the aluminum solar panel frame is directly linked to the anodizing process. The average thickness of the oxide film of ordinary aluminum alloy profiles is 10μ, while the aluminum solar panel frame should reach 15μ. Because the aluminum solar panel frame is exposed to the outdoor environment for a long time, it is easy to cause frame corrosion in bad weather.
4. Deep processing accuracy, the deep processing process is very important, deep processing includes bevel cutting, punching installation holes, sink holes, grounding signs, riveting points, plug angle codes, etc. If it is produced on an automatic line, it is fine. If it is a manual line or a semi-automatic line, you must be careful not to miss processing. Because the frame assembled by the group frame factory cannot be disassembled, if it is found that there are no installation holes during installation, the entire battery board will be scrapped. When the frame is assembled, there will be very few cases of frame explosion, that is, due to the excessive size of the aluminum solar panel frame, the battery board is broken. Since the cost of photovoltaic module panels is relatively high, the losses are also relatively large.
