What bolts are used in photovoltaic projects

The reason why the photovoltaic industry has attracted global attention is that the energy source of photovoltaic power generation - solar energy - is clean, safe, and renewable. The process of photovoltaic power generation does not pollute the environment or damage the ecology. The rapid development of the photovoltaic industry has also brought more opportunities to the fastener industry. So, what should we pay attention to when choosing fasteners in the photovoltaic field?

Most of the equipment in photovoltaic power generation projects, such as solar brackets, need to be exposed to outdoor environments for a long time. Therefore, corrosion-resistant and impact resistant fasteners should be selected to ensure the service life of the equipment. Therefore, various stainless steel fasteners are preferred, such as various stainless steel hexagon bolts, nuts, etc.

Outdoor environments often encounter various climate changes, such as strong winds, heavy rain, etc., which require high stability of equipment. Various anti loosening measures should also be considered, such as double layered self-locking washers, serrated washers, locking nuts, spring washers, etc. Various combination screws and flower shaped screws can also play a certain anti loosening role in photovoltaic projects.

The installation angle and position of solar panels in photovoltaic projects are very important, as they are related to whether sufficient solar energy resources can be utilized. Therefore, there is a certain demand for fasteners that are easy to install and accurately positioned, such as T-slot bolts that can automatically position and lock, and plastic wing nuts that are structurally simple to install and easy to position.

The installation space of solar brackets is limited. In order to save installation space, reduce equipment weight, and optimize structural design, it is necessary to choose a connection form with high strength, small volume, and high preload force. Hexagonal socket screws with precise design, capable of withstanding large installation torques, and able to be installed in aluminum profile grooves are commonly used, such as Phillips head screws.

In order to cope with outdoor environments such as rain, the connection of various parts of photovoltaic panels needs to have a certain degree of sealing, so it is necessary to use plastic gaskets that can seal waterproof. At the same time, in order to save installation time and improve standardized operation efficiency, the fixing of photovoltaic panels requires the use of fasteners that are easy to install and maintain. Drill tail screws that have high strength, good toughness, corrosion resistance, are inexpensive and aesthetically pleasing, and are easy to install and do not require maintenance are more suitable.
