Have you installed the screws on the photovoltaic solar panel correctly? 

In recent years, the country has been vigorously promoting the development of the photovoltaic industry. "Photovoltaic poverty alleviation" is even one of the "top ten poverty alleviation projects". This is because of the environmental friendliness and renewability of photovoltaic power generation, the photovoltaic industry has experienced explosive growth worldwide. Our fasteners have also been chosen by more and more photovoltaic projects. Yesterday, we shared with you the precautions for choosing fasteners in the photovoltaic field. Today, let's talk about the installation issues of photovoltaic fasteners. Imagine, photovoltaic projects that cost millions or even billions, which could operate for 25 years or more, just because a small screw was not installed correctly, and after using it for three or five years, various faults occurred. How much loss would there be?

Therefore, in the field of photovoltaics, not only should the screws be chosen correctly, but also their proper usage should be paid attention to.

To sum up, the correct installation method for fasteners in photovoltaic power stations:

1.The spring washer should be placed behind the nut so that its elasticity can be utilized to increase the friction between the nut and the bolt, preventing loosening and detachment.

2.There must be flat washers beneath the bolt and nut to increase the bearing area. If there are also spring washers, remember to place the spring washer on top of the flat washer, closer to the nut.

3.The number of flat washers should not be excessive. For a single bolt, the maximum number of flat washers that can be placed is When there is a nut, only 1 flat washer can be placed. Placing too many washers can cause loosening. The above installation methods can be regarded as common knowledge for fastener installation. However, during actual operation, errors can still occur due to carelessness. Therefore, everyone must pay attention to this issue. Do not let a small mistake affect the smooth operation of the entire photovoltaic project.
