The solar racking system is also known as a photovoltaic mounting system. It is used to fix solar panels on different surfaces like roofs, ground.
For flat rooftop the racking system is installed so the solar array is aligned at an angle. Solar mounting systems can be part of the initial construction of the building or can be put on an existing roof.
Ground-mounted solar panels are usually for large-scale utility stations. The solar arrays are attached to the racking system with its foundation directly into the ground.
