What the numbers suggest

It mostly installs systems homeowners own.
A long track record (14 years in records) is a good sign for honoring a workmanship warranty.

Before you sign with any installer

Verify the contractor license and look for complaints with your state board and attorney general.
Get at least three quotes and compare them in our quote comparison tool.
Ask who does the installation (their own crews or subcontractors) and who backs the workmanship warranty.
Read our solar sales red flags.
