How to Read a Solar Quote in 2026 (And Spot the 5 Tricks That Cost You Thousands)

Most solar quotes are designed to be hard to compare. Different system sizes, different finance terms, hidden fees, fuzzy production estimates — it's not an accident. If every quote were apples-to-apples, you'd just pick the cheapest, and a lot of companies can't win that fight. Here's how to read a solar quote the way we do, so nobody can slip one past you.

1. Start with price per watt, not the total

The total price means nothing until you divide it by system size. Take the system cost and divide by the number of watts (an 8 kW system is 8,000 watts). That gives you price per watt — the one number that lets you compare two quotes fairly. If one quote is wildly higher per watt, ask why. We get into real pricing here: how much does solar cost in 2026.

2. Find the "dealer fee" hiding in financed deals

$0-down loans almost always carry a dealer fee — sometimes 10–30% baked into the price — to cover the cost of that low interest rate. It's rarely on its own line. The tell: a financed quote that's thousands more than the cash price for the identical system. Always ask for both the cash price and the financed price, and compare them.

3. Check the production estimate against reality

A salesperson can make the savings look huge by assuming the system produces more electricity than it actually will. Look for the estimated annual production in kWh, and be skeptical of numbers that assume a perfect south-facing roof with zero shade if that's not your house. A credible quote uses your real roof, pitch, and shading.

4. Watch the escalator on leases and PPAs

If you're looking at a lease or PPA, the most important number is the annual escalator — the percentage your payment climbs every year. A 2.9% escalator compounds into a much bigger bill a decade in. A flat (0%) escalator is far safer. We compare ownership types here: lease vs PPA vs loan vs cash.

5. Separate the battery from the panels

Batteries are the most over-sold part of a quote. They're great for backup power and certain rate structures, but they can add $10,000+ and dramatically change your payback. Ask for the quote with and without the battery so you can decide if it's worth it for you. Here's when one actually pays off: do you really need a solar battery?

The 2026 tax-credit footnote

One more thing to watch: the 30% federal residential tax credit expired December 31, 2025. If a 2026 quote still shows a "30% federal tax credit" line knocking down your cost on a cash or loan purchase, that's a red flag — it no longer applies to homeowners who buy. Make sure the numbers you're comparing are the real, after-2026 numbers.

The simplest way to never get tricked

Get more than one quote, and have someone who isn't trying to sell you a specific product compare them. That's exactly what we do as an independent broker — we line real quotes up side by side, translate them into the same units, and point out the fees and assumptions buried in the fine print.
