Independent · No installer affiliations · 2-business-day turnaround
A solar quote is a $30,000–60,000 decision written by a salesperson. For $19, get an independent engineering review — grounded in power-electronics and solar PV expertise — that tells you if the price is fair, the equipment is good, the loan hides fees, and whether the production promise survives a physics check.
Solar itself is usually a good idea. Solar quotes are another story — the same three problems show up again and again.
Every review runs the same disciplined methodology and ends with a letter grade, the findings in plain English, and exactly what to negotiate or walk away from.
Your price per watt, benchmarked against current market data for your state and system size — and the dollar figure you should actually be paying.
The exact panels, inverters, and battery quoted, rated against our maintained tier list — warranty, degradation, and whether the electronics fit your roof.
Dealer fees hidden in the loan, escalator clauses, tax-credit assumptions, and what the payment really adds up to over the full term.
The salesperson's kWh promise, tested against the National Laboratory of the Rockies' PVWatts model for your actual roof, tilt, and location.
No account, no sales calls, no follow-up spam. One quote in, one report out.
One quote is $19; bundle 2 for $29 or 3 for $39 to compare quotes for the same home. Secure checkout by Stripe.
The PDF or photos the installer gave you, your most recent electric bill (all pages), and your address for the physics model.
Letter grade, findings in plain English, negotiation asks with target numbers, and walk-away conditions.
Smart — comparing quotes for the same home is where a second opinion pays off most. Send us all of them and we'll tell you, head-to-head, which one is the best deal.
A full independent review of one quote — price, equipment, financing, and a physics check of the production estimate.

Every report is prepared by an engineer with a PhD in electrical engineering — specialized in power electronics and solar photovoltaic converter design — using modern analysis tools plus published market data. We have no relationship with any installer, lender, or manufacturer, and we don't sell leads. The only thing we sell is the truth about your quote.
Expiring-price pressure is the industry's favorite tactic, and it is almost never real. Any installer who wants your business will honor their price next week. A quick independent review costs you a day or two and can save you thousands.
A written report: an overall letter grade; a line-item read of your system's price, equipment, financing, and production estimate; the specific dollar amounts to negotiate; the questions to ask your installer; and the conditions under which you should walk away.
Then the report says so — and you sign with confidence instead of doubt. Around some markets' honest installers, that's a real outcome. If the review surfaces nothing you find useful, we refund your full fee (within 14 days).
Never. Your quote is used for your review only, stored privately, and deleted on request. We are not a lead-generation site; we have no installer partners to send anything to.
Yes — batteries are covered in the equipment and sizing checks, and lease/PPA offers get the same financing scrutiny (they usually need it most).
No. It's independent technical analysis for consumer education — think of it as a very well-informed second opinion, not a stamped engineering certification or investment advice.
