Solar panels can boost home values by up to $79,000

Think solar panels only add a modest bump to your home's value? Think again. Research analyzing 5,000 California home sales shows that solar installations are driving property value increases of 5% to 10%—more than double previous estimates. For the average $790,000 California home, that's an eye-popping $39,500 to $79,000 boost in resale value.

This isn't just about monthly electric bill savings anymore. The data shows solar panels have become one of the most valuable home improvements you can make, delivering returns that exceed traditional renovations while providing decades of energy independence.

With the average solar panel system costing about $30,505 before incentives, homeowners may be able to recover the full cost of the system through property value increases alone—before you even factor in years of electricity savings.

For years, the solar industry relied on a 2019 Zillow study showing solar panels added about 4.1% to home values. But 2025 research conducted by SolarInsure provides a newer picture. It analyzed 5,000 California home sales between 2020 and 2023, comparing 2,350 homes with owned solar systems against 860 comparable homes without solar and 1,790 homes with third-party-owned solar.

The findings are striking: Homes with owned solar panels sold for 5% to 10% more than similar homes without solar, a significant jump from Zillow's 2019 study.

System age played a smaller role than expected. Solar installations over five years old still earned a 5% to 6% premium, while newer systems saw 7% to 9% increases. This suggests buyers value the long-term savings potential more than the newest technology.

To ensure accurate comparisons, researchers matched each solar home with three non-solar properties of similar size, age, and amenities in the same area. They also used the Case-Shiller Home Price Index to account for market fluctuations over the study period.

According to EnergySage data, the average 12-kilowatt system costs about $30,500 before incentives. The average U.S. home value as of May 2026 is $403,200. So, if your home's value increases by just 5% due to solar, it would cover over $20,000 of your systems cost through increased property value alone—before counting decades of electricity savings or available incentives.

Several factors drive solar's impressive impact on home values:

• Guaranteed cost savings: Buyers are purchasing decades of reduced electricity bills. With average household electricity costs skyrocketing, solar represents protection against future rate increases.

• Energy independence: As power outages become more frequent and utility rates climb, solar paired with storage offers stability and resilience.

• Quality investment signal: Solar installation demonstrates that homeowners have made thoughtful, long-term improvements to the property.

• Immediate benefits without upfront costs: New homeowners inherit the solar system's benefits without the initial investment or installation disruption.

• Growing market awareness: As solar becomes mainstream, more buyers understand and appreciate its value proposition.

The new research confirms that ownership can make a big difference when it comes to home solar. Homes with third-party-owned solar—leased or power purchase agreement (PPA) systems—showed no value increase compared to homes without solar.

This distinction becomes even more significant given the current federal policy. While the residential tax credit ended in 2025, the commercial tax credit continues for systems that begin construction before July 2026 or are placed in service before 2028. This means companies offering leases and PPAs can still claim tax credits for systems and may pass those savings to homeowners, but you wouldn't see those savings reflected in property values.

That said, leases and PPAs serve an important purpose for many homeowners. They provide immediate electricity savings with no upfront cost and no maintenance responsibilities, allowing homeowners to keep their capital flexible.

The property value consideration primarily affects traditional lease and PPA structures where the solar company retains ownership through the life of the agreement. From a buyer's perspective, these arrangements can sometimes present complications if new homeowners don't want to inherit monthly payments and contract obligations.

However, some newer prepaid lease and PPA products offer a path to ownership before you sell your home. If you buy out or complete payments on your agreement and own the system outright by the time you list your property, you may see the same property value increases as systems purchased from day one.

Compared to other popular renovations, solar delivers superior returns. National Association of Realtors data shows complete kitchen remodels recover about 60% of their cost at resale, while bathroom renovations typically see 50% cost recovery.

Solar panels can offer 100% cost recovery through property value increases alone, plus ongoing electricity savings. Unlike renovations that primarily enhance aesthetics or comfort, solar provides measurable, quantifiable financial benefits.

Installation is also relatively painless. While kitchen or bathroom renovations can take months and disrupt daily life throughout, a typical solar installation is complete in one to two days.

For most homeowners, solar is a smart investment. Equipment costs have dropped significantly—EnergySage Intel's latest Marketplace Report shows prices hover at about $2.58 per watt as of June 2026, down from over $3.80 per watt in 2014.

At the same time, household electricity costs are expected to increase immensely as utilities expand capacity to meet growing demand. With electricity prices historically increasing around 2.8% annually, the value of solar's fixed energy costs becomes more significant each year.

The 5% to 10% property value increase reflects the market's recognition of solar as a valuable, long-term asset. It's one of the few home improvements that can pay for itself through property value increases alone and then deliver decades of additional savings.

When homebuyers purchase homes with solar panels, they gain energy savings and grid independence—benefits that continue to drive demand and value. Solar remains one of the smartest investments you can make in your home, offering returns that few other improvements can match.
