What you get
A straight answer, in plain English.
Not a lead-capture form that hands your number to three installers. A PDF you can read in five minutes and take to any quote.
Your payback year
The year your savings pass what the system cost, after any state incentive, now that the federal credit has ended for 2026 buyers.
The right system size
Sized to your actual usage and your roof's sun, with the estimated cost before and after incentives.
25-year savings
Year-by-year break-even with realistic rate rises and panel wear, so you see the whole picture, not a sales headline.
The payback timeline
Your savings, tallied year by year.
This is how the PDF reads for the Phoenix sample above: each year's savings added to a running total until it clears the net cost.
Illustrative figures for the sample home, with rate rises and panel wear modeled. Your timeline runs on your ZIP, your bill, and your utility.
Why trust it
We're not the ones selling you panels.
Installer calculators are built to make the answer look good, and most still apply a federal credit that no longer exists for 2026 buyers. This report uses the same public NREL and EIA data an independent engineer would, and it tells you when solar is a slow payback in your state, too.
Know your number before you pick up the phone.
Fifteen dollars, a couple of minutes, and you'll never wonder if a quote is fair again.
