There are many different technologies and installation options. I’m gonna tell you about two common installation options. If you choose another kind of installation, be aware that of the many design, drainage, warranty, and repair concerns discussed in this article are common to all installation systems.
Ballast solar panel system
If you do not wish to alter the roof of your home or business, one option is the ballast system, which works best on a flat commercial roof. With this installation method, the panels rest on top of the roof. While this is the least expensive option, it has several drawbacks that may factor into your decision.

The ballast mounting system places excessive weight on the roof, which makes the roof membrane brittle and easily cracked.
Panels are required to be mounted at acute angles, about 0-20 degrees, to avoid destabilization because of the wind.
