What the numbers suggest

Prices on owned systems run somewhat above the average in the same state and year.
It installs a mix of owned and leased systems.
A shorter track record (6 years in records) means more uncertainty about long-term warranty support. Ask who backs the workmanship warranty if the company closes.
Batteries are a large share of its installs. Check whether a battery actually pays off for you before agreeing to one.

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.
