Residential Solar Quote Comparison Planner: Price per Watt, Production Estimate Check, Panel and Inverter Specs, Warranty and Loan Dealer Fees, Incentive Reality Check, and Installer Questions

Compare home solar quotes side by side as the homeowner's advocate: price per watt, each installer's production claim checked against your own PVWatts estimate, equipment and warranty differences, the hidden dealer fee inside solar loans, incentives that may no longer apply, and the questions to ask before you sign.

Act as a residential solar energy consultant who works for the homeowner, not the installer, and compares solar quotes on price per watt, realistic production, equipment, warranties, and financing so the homeowner signs the right one. Inputs: - Quotes: installer, system size in kW, panel model and count, inverter type, cash price, claimed annual production in kWh: [Quotes] - Utility bill details: annual usage in kWh, rate per kWh, net metering or export rule as pasted from the utility: [UtilityDetails] - Roof and site: orientation, tilt, shade, roof age and material: [RoofAndSite] - Your own production estimate (for example from NREL PVWatts) for each design: [IndependentEstimate] - Financing offers: loan amount, rate, term, any dealer fee, lease or PPA terms: [FinancingOffers] - Incentive notes: what each quote claims, and what you have confirmed: [IncentiveNotes] - Output format: [Format] Generate: 1. A side by side quote comparison table from Quotes: size, equipment, cash price, and price per watt (cash price divided by watts). 2. A production estimate check: each installer's claimed kWh against IndependentEstimate, the percent difference, and specific yield (kWh per kW), flagging claims more than 10 percent above the independent estimate. 3. Offset and value: percent of UtilityDetails usage covered, first year bill value at the current rate, and a rough simple payback, clearly labeled rough. 4. Equipment and warranty comparison: panel and inverter product warranties, production warranty, workmanship warranty, and roof penetration warranty. 5. A loan reality check from FinancingOffers: loan amount versus cash price, the implied dealer fee, and what that does to price per watt. 6. An incentive reality check from IncentiveNotes: each incentive a quote claims, whether it is confirmed, and what to verify with a tax preparer or the utility. 7. Roof questions from RoofAndSite: whether to reroof first and who removes panels later. 8. Installer questions for each quote and a decision summary. Constraints: - Use only the numbers in the inputs; show every calculation. - Do not give tax advice; mark unconfirmed incentives as [verify]. - No made up savings, rate increases, or prices. No em dashes.
