Solar system support, also known as racking or mounting, secures solar panels to a building or the ground. 

Support structure materials 

Aluminum, Steel, I beams, Channels, Posts, Helical piles, and Earth screws.

Ground-mounted structures 

Foundations can be driven (I beams, channels, or posts) or screwed (helical piles and earth screws)

Roof-mounted structures 

Solar panels perform best on south-facing roofs with a slope between 15 and 40 degrees

Support structure considerations 

The structure should be stable and durable

It should be able to withstand wind, rain, hail, and corrosion

The structure should tilt the panels at a fixed angle based on the local latitude

For ground-mounted systems, tracking mechanisms can increase energy output
