How to install photovoltaic bracket purlin

What is solar panel support with Z profiles and purlins brackets?

Solar power systems use the sun’s rays as a high-temperature energy sources to produce electricity in a thermodynamic cycle. Thereby we have to introduce some solar panel support with Z profiles and purlins brackets, which are hot galvanized steel material for use in long time with better surface and the best cost during the system construction.
