Do solar panels actually increase home value in 2025? The answer is a resounding yes. Multiple studies from Zillow, Lawrence Berkeley National Laboratory (LBNL), and Redfin confirm that homes with owned solar systems sell for $15,000–$29,000 more on average. With energy costs rising, eco-conscious buyers dominating the market, and appraisal practices now recognizing solar as a true asset, adding solar is one of the few home upgrades that pays off twice: through energy savings and resale value.

The 2025 Research – Exact Numbers
In 2025, the evidence is overwhelming: solar panels reliably increase home value. Across multiple studies (Zillow, LBNL, Redfin, DSIRE, and national appraisal guidelines), the average uplift for an owned solar system ranges $15,000–$29,000 for a 6–8 kW system.
National premium: 6.9%
Value per watt: $4.10–$5.90
Average system size considered: 6–8 kW
Homes sell faster: 20% quicker
Why values are higher in 2025:
Rising electricity costs: +15% nationwide since 2022, making solar savings more attractive.
Shifts in buyer preference: Over 80% of homebuyers now consider energy efficiency a priority.
Appraisal recognition: Owned systems are now explicitly valued in 90% of appraisals.
Story Example:
In Riverside, CA, two identical homes were listed side-by-side in March 2025. The home with a 7 kW owned solar system sold for $463,000, while the non-solar home sold for $450,000 — a $13,000 premium, achieved in 2 days less on market.

Owned vs. Leased – Why $30K Matters
Owned solar systems:
Add $15K–$29K
Sell 20% faster
Attract more buyer interest
Qualify for appraisal contributory value
Leased / PPA systems:
Usually $0 added value
Can reduce buyer interest due to credit checks
Some appraisers assign zero contributory value
Can delay sales due to contract transfer issues
Example: A 7 kW leased system in Miami, FL, sold with no premium and required buyer approval of the PPA contract — compared to the neighboring owned solar home, which sold $25,000 higher.
