Quick answer
The practical explanation
Ask about licensing requirements, experience, roof assessment, system size and production assumptions, total cash and financed cost, equipment, permits, utility approval, warranties, maintenance, monitoring, cancellation terms, and what happens if the roof or home is sold.
What to know
Three points to keep in mind
- Compare multiple detailed written bids.
- Do not rely on verbal promises that are missing from the contract.
- Take time to review financing, transfer, roof-repair, and performance terms without pressure.
For your home
A site-specific answer still matters
Solar results and service needs depend on the roof, equipment, shade, household electricity use, utility requirements, and the condition of the existing system. Use this guide as a starting point, then have the property and equipment evaluated before making a major decision.
