Photovoltaic brackets are outdoor installations. Therefore, water accumulation is a very common phenomenon under the influence of weather, but we should not underestimate it, because once the water is accumulated and not treated in time, it will bring serious harm to the photovoltaic bracket. Moreover, the airtightness of the photovoltaic support is good. How can water enter the interior? Explain in detail about the doubts in these two aspects.
If water accumulates in the photovoltaic support, it will directly cause corrosion of other parts, especially some standard parts used for connection and fastening, thereby threatening the normal operation of the entire photovoltaic support. In view of the hazards in this regard, once a similar phenomenon is discovered, it should be handled promptly and properly.
After a careful and comprehensive inspection, it was discovered that the photovoltaic stent would enter water mainly because there are zinc drain holes reserved on the top side. Rainwater will enter the photovoltaic stent along the holes if it is not fully covered. There is also a possibility that rainwater penetrates from the flange connection of the photovoltaic bracket. For this, we can only find ways to improve the sealing of this piece.
