Solar Panel Home Purchase Calculator

Calculate the true cost of buying a home with solar panels. Factors in system age, maintenance costs, roof risks, and lease obligations.

Solar Complicates Everything. Don't Wing Your Offer.

This calculator shows you the solar-specific costs. But what should you actually offer for this property? Solar liabilities, maintenance risks, and roof replacement costs need to be factored into your offer price and negotiation strategy.

Most buyers see "$15K solar lease obligation" and think "I'll just deduct that from my offer." But the math is way more complex - especially with aging systems, roof risks, and market comparables.
