The solar photovoltaic bracket is a special bracket designed for placing, installing and fixing the solar panel in the solar photovoltaic power generation system. People who have some knowledge of PV know that the selection of PV support is very important for the installation of PV system components, because some inferior PV supports will not only cause problems in installation, but also lead to the destruction of PV modules in severe weather, such as Taiwan storms and snows, causing economic losses and affecting people's life safety.

First of all, the PV support structure must be firm and reliable, and can withstand such external effects as atmospheric erosion, wind load and others. It shall have safe and reliable installation, can achieve the maximum use effect with the minimum installation cost, is almost maintenance free, and has reliable maintenance. The following factors should be considered for a good support:

(1) The strength of the material must withstand climatic factors for at least thirty years.

(2) It will not be affected in extreme weather, such as snowstorm or typhoon.

(3) The bracket shall be designed with channel rail to place wires to prevent electric shock.

(4) The electrical equipment shall be installed in a non exposed environment and easy for regular maintenance.

(5) It must be easy to install.

(6) The cost should be reasonable.

High quality PV support system must use computer simulation software for extreme weather conditions to verify its design, and carry out strict mechanical property tests, such as tensile strength and yield strength, to ensure the durability of the product.

Therefore, these factors must be taken into account when selecting supports.
