Does Solar Increase Home Value? The 2026 Appraisal Data

Solar homes sell for about 4.1% more, per Zillow data — roughly $9,200 on a median US home. Here is the real data on solar home value and how to protect it when selling.

The data is clear

Zillow found solar homes sell for ~4.1% more — about $9,200 on a median US home. Lawrence Berkeley National Laboratory found buyers pay a premium of about $4 per watt of installed solar. A 6 kW system adds roughly $24,000 to resale value in active markets.

Owned systems add value; leases complicate sales

Owned solar consistently adds value. Leased/PPA systems can complicate a sale because the buyer must assume the lease — some sellers must pay off the lease or offer concessions. If you may sell within 5–10 years, ownership is the safer bet.

What appraisers look for

Appraisers value solar based on age, size, ownership, and local comps. Keep documentation: system size, install date, production data, and warranty paperwork. A clean owned system with 25-year warranty is a selling point, not a liability.
