SolarCheck – Solar Quote Checker

SolarCheck reviews a U.S. home solar quote or proposal and points out issues worth asking about before you sign.

What you provide

• Your installer's quote or proposal (pasted text or key numbers): system size, price, panels/inverter, financing terms, production estimate and savings claims
• Your state and, if available, your annual electricity use and current rate

What it checks

• Price per watt, compared with your other quotes and a rough typical range
• Whether the production estimate looks reasonable for your region
• Savings claims, recalculated with your own rate and export-credit assumptions
• Tax credit wording (for example, the 30% homeowner credit under Section 25D ended for systems placed in service after 2025)
• Loan terms such as APR and dealer fees, and lease/PPA escalators
• Missing items such as warranties, production guarantees or license details

What you get

• A table of the quote terms it found (and what is missing)
• A check-by-check summary with flags
• Specific questions to ask your installer

Limits — please read

• This is informational issue-spotting only. It is not financial, legal, tax, engineering or compliance advice.
• It does not tell you whether a quote or contract is safe to sign, and it does not replace review by a licensed professional, attorney, tax advisor or your state contractor board.
• Results depend on the information you provide; prices, incentives and rules change and vary by state and utility.
• It does not verify an installer's license, insurance or reputation.
