What is the biggest solar quote red flag?

A decision case that cannot be reconstructed from written price, system size, production, utility, financing, equipment, and incentive inputs.

Does a red flag prove a solar company is a scam?

No. It identifies missing or inconsistent information that should be resolved before signing. Verify identities, licenses, documents, and claims independently.

What should I do if the offer expires today?

Do not let an artificial deadline replace due diligence. Request the complete offer and contract in a form you can save and compare.

Solar Quote Red Flags: 12 Checks Before You Sign

A red flag is a reason to verify a claim in writing—not proof that every unfamiliar term is dishonest.

High-pressure timing and complex financing can make a proposal feel harder to compare than it is. Use these checks to identify missing facts, conflicting numbers, or assumptions that deserve a written answer.

Price and financing red flags

Compare the solar-only cash price with the financed principal. CFPB research describes dealer fees that can increase the price embedded in some solar loans, so a monthly payment alone is not enough to compare offers.

No itemized cash price or financed price.
Price per watt mixes in a battery, roof, or unrelated work.
APR is emphasized while fees, term, or total of payments are hard to find.
A future payment change assumes the homeowner will contribute an incentive or tax refund.

Production and savings red flags

Savings are forecasts. They should disclose production assumptions, utility rates, export compensation, degradation, and escalation. Treat a guaranteed-sounding savings statement without those inputs as a question to resolve.

Only a lifetime savings total, with no annual or monthly inputs.
Every generated kilowatt-hour is valued at the full retail rate despite lower export credits.
The proposal does not identify the production model or roof assumptions.
The system size is not reconciled to annual household usage.

Equipment, warranty, and contract red flags

Exact models and written warranty responsibility matter because brand families can contain different products and coverage. The contract should also explain cancellation, change orders, roof work, interconnection, permission to operate, and what happens if promised equipment is unavailable.

Generic panel or inverter brand with no model number.
A warranty duration is shown but labor, shipping, roof penetration, or transfer terms are absent.
Verbal promises do not appear in the signed documents.
The salesperson discourages comparison, source verification, or time to read the contract.
