People in the industry know that the requirements of aluminum solar panel frames are much higher than those of ordinary industrial aluminum profiles and aluminum products, and the price is higher than that of ordinary industrial aluminum profiles. Why? Let us answer for you below.
We all know that solar panels must be used outdoors for power generation, and we must choose a place with sufficient sunshine. Long-term sunshine and rain will shorten the life of the solar aluminum frame. In addition, some areas with severe weather will have sandstorms and hail, all of which require high product quality.
The life span of a solar panel can reach 15-25 years, and the life span of the aluminium solar frame must not be less than this period. Therefore, the oxide film thickness of solar aluminum frame is generally more than 5μ thicker than industrial aluminum profile.
In fact, the explosion frame is not an explosion solar aluminum frame, but a glass panel. If the solar aluminum frame is easy to handle, the cost of a whole panel will cost thousands of dollars
If the tolerance of the solar aluminum frame is unqualified, it will cause heavy losses if the frame bursts. Therefore, industrial aluminum profile suppliers need to inspect when we produce solar aluminum frames, and each one must be inspected carefully.
The solar aluminum frame we use now is not like bolting the group frame in the past. Now they are all connected by corner code, and then rushed to the riveting point. This connection method is very beautiful and generous, but there is also a drawback, that is, it cannot be removed. If a set of finished solar panels is assembled and it is found that mounting holes or sink holes are missing on the solar aluminum frame, the entire solar panel can only be scrapped. So we need root inspection after all the processes are processed.
The above are the main three factors. It can be seen that each set of solar aluminum frame products are strictly inspected according to the procedures, which is very difficult.
