What the numbers suggest
- Prices on owned systems run well below the average in the same state and year.
- It mostly installs systems owned by leasing or PPA companies. If you want to own your system, ask for a cash or loan quote and compare it with a lease carefully.
- A long track record (18 years in records) is a good sign for honoring a workmanship warranty.
- Batteries are a large share of its installs. Check whether a battery actually pays off for you before agreeing to one.
