Solar Panel Cost by State publishes free, independent solar pricing data, state-by-state cost and incentive guides, and a solar cost calculator. The goal is narrow and practical: help you estimate what a rooftop solar system should cost in your state in 2026 — gross price, available incentives, and realistic payback — before you start taking installer calls, so you can budget honestly and recognize a quote that's out of line.
We're an independent publisher, not a solar installer, a lead broker, or a financing company. We don't sell systems, we don't book your installation, and we don't sell your details to a call center. Everything on the site is free to read and use.
Who this site is for
If you're a homeowner trying to answer "what will solar actually cost me here, and how long until it pays for itself?", you're who we build for. Our guides cover system size, gross and net pricing, state and utility incentives, financing trade-offs, and payback periods, so you can match a system to your roof, your bill, and your budget.
How our content is produced
Our guides are researched and drafted with the help of AI-assisted tools and then reviewed and edited for accuracy before publishing. We compile cost figures from sources we can point to, rather than guessing:
- Published installer and marketplace pricing — per-watt installed costs and quoted system prices from solar installers and quote marketplaces, used to build the state cost ranges.
- U.S. Energy Information Administration (EIA) for state residential electricity rates, and the National Renewable Energy Laboratory (NREL) for benchmark installed-cost and production data.
- DSIRE and state/utility program pages for current incentives, rebates, net-metering rules, and tax treatment, including the expiration of the 30% federal residential credit (Section 25D) after December 31, 2025 under the 2025 budget law.
Where a figure comes from a specific dataset, we say so in a methodology line on the page itself.
How we keep the lights on
The site is supported by advertising and by affiliate links to solar accessories such as portable panels, solar generators, and battery banks. As an Amazon Associate we earn from qualifying purchases. Affiliate links never change the price you pay, and they don't influence our cost figures or recommendations — you can't buy a rooftop install on Amazon, so these links cover gear only, never the system itself.
