How do I install solar panels on a lightweight tile roof?

The best way to install solar panels on a lightweight tile roof is through a method called inset solar installation, also known as a “comp-out” installation. This technique removes the section of tile where the solar panels will be installed and replaces it with composite shingles before mounting the solar array.

Can a tile roof handle solar panels?

If you have a tile roof and are considering solar energy, you might be wondering whether your roof can handle solar panels.

How do you install solar panels on a new roof?

Should you install composite shingles under solar panels?
