Solar Panel Installation

We're glad you’re thinking solar. Installing solar panels on your roof will not only help the environment, but also save you money on your electric bills.

The Code Enforcement Department would like to help you easily navigate the process of upgrading your home with solar panels through our department. The process for a solar installation on your home involves the same permits and inspections that most home improvements require.
