What a typical solar quote includes
Most quotes will show the core parts of the project: equipment (panels, inverters), labor and installation, permitting and interconnection fees, and any third-party costs like structural work. Some quotes include an itemized list of incentives or rebates; others present a single ‘net price’ after assumed incentives. National installers such as Sunrun or Palmetto Solar sometimes offer bundled pricing or pre-filled incentive estimates, while local installers may show a more granular line-by-line breakdown. Always ask for a clear separation between the gross system cost and any incentives or credits that reduce your out-of-pocket expense.
How incentives and tax credits are applied to quotes
Incentives fall into a few categories: federal tax credits, state or utility rebates, and ongoing program credits like performance payments or net metering. Tax credits are typically claimed on your tax return, so they don’t always come off the installer’s invoice unless the installer or lender has a specific arrangement to pass them through. Rebates and upfront incentives may be applied to the invoice if the installer handles the paperwork or if the utility pays the incentive directly to the installer. Because practices vary, confirm who will apply for each incentive, whether the quote assumes you qualify, and whether the estimated incentive amount is guaranteed or only an estimate.
How to compare quotes (what to check)
Compare the same items across quotes, not just the bottom line. Key things to check: gross system cost; line items for incentives and the resulting net cost; equipment models and expected production; who pays for permits and interconnection; timing for permits and installation; whether the installer will handle incentive paperwork; and financing terms or lease details if offered. Also compare installer credentials and local references. National brands can have standardized offers and finance partners, while local installers may be more flexible about pricing and paperwork for local programs. Tradeoffs include standardization and ease of financing versus local knowledge and personalized service.
Questions to ask before you request or accept a quote
Ask the installer to show the gross price and then list each incentive or rebate separately so you can see the net price. Ask who will apply for and receive each incentive, and whether amounts are estimated or guaranteed. Confirm how the federal tax credit is handled and whether any part of it will be passed through or simply reflected as an estimated tax benefit. Request the equipment make and model, an estimated production figure, and sample invoices or contracts that show actual incentive handling. Finally, compare how national companies like Sunrun or Palmetto Solar present these items versus local installers so you know whether you’re comparing apples to apples.
