Solar Increases Home Value in Northern California: Data & Trends for Solano, Napa & Sacramento

Why Homeowners in Northern California Are Choosing Solar

If you’re considering solar for your home in Northern California, you’re not alone. Beyond lowering utility bills and reducing carbon emissions, solar panels—and especially systems paired with battery storage—can increase home resale value in markets like Solano, Napa, and Sacramento counties.

By understanding the latest data and real estate trends, you can make more informed decisions about going solar now and optimizing your future return on investment (ROI).

Real Data: Solar Adds Resale Value to Homes

Multiple studies show that solar installations often add measurable value to homes when they hit the real estate market. For example:

• Homes with solar panels sold for 6.9% more on average than comparable homes without solar in a 2025 study, translating to roughly $29,000 added value for a median-priced home. 

• Earlier research by Zillow found solar homes sell for about 4.1% more than non-solar homes, illustrating consistent valuation premiums over time. 

• A Lawrence Berkeley National Laboratory analysis from California data suggests solar can add approximately $3.9 to $6.4 per installed watt in home sales price premium—about $17,000 for a typical 3.1 kW system. 

These figures show solar doesn’t just save on energy bills—many buyers are willing to pay more for homes with owned solar systems because it represents future utility savings and sustainability. 

How Solar Value Plays Out in Northern California Markets

In regions like Solano, Napa, and Sacramento counties, homes face some of the highest electricity rates in the country. Buyers in these markets often recognize the financial benefit of rooftop solar because:

• Solar helps hedge against rising utility costs

• Solar paired with storage increases resilience (e.g., backup power during outages)

• Energy efficiency and sustainability are increasingly desirable to buyers

That local demand makes owned solar systems a strong selling point for future buyers—especially when systems are well-designed and properly maintained.

Battery Storage: Adding Extra Value

Solar paired with battery storage is increasingly attractive to homebuyers. Battery systems provide backup power during outages—a major selling point in regions that experience extreme weather or grid stress.

In fact, studies show solar homes with batteries usually command even higher resale expectations than solar alone. Buyers see battery-backed solar as a “future-proof” feature that improves performance, reliability, and energy independence.

What Home Appraisers Are Seeing

Appraisers and real estate agents increasingly include solar systems in valuation models because they impact both utility cost savings and property desirability.

Key appraisal considerations typically include:

• System ownership: owned systems add more value than leased or financed ones. 

• System age and condition: newer panels and up-to-date technology appeal more. 

• Local utility rates: high regional rates increase perceived solar savings, thereby increasing valuation. 

In competitive Northern California sellers’ markets, homes that come with fully owned solar panels and excellent paperwork often get more interest and higher offers.

Industry Data Shows Solar Increases Home Value

Multiple independent studies confirm that homes with solar energy systems tend to sell for more than comparable homes without solar. Research from nationally recognized real estate and energy organizations shows buyers are willing to pay a premium for homes with owned solar panels because of long-term utility savings and energy efficiency.

According to a widely cited study by the Lawrence Berkeley National Laboratory, homes with solar systems consistently command higher resale values, with premiums tied to system size and ownership status.

This data reinforces what many Northern California homeowners are already seeing in local markets—solar is increasingly viewed as a valuable home improvement, not just an energy upgrade.

How Solar Impacts Time on Market

Beyond raw resale value, solar can influence how quickly a home sells. Recent market data shows homes with solar installations sell faster than homes without—suggesting buyers view solar systems as a desirable asset. 

This faster turnover can make solar not just a value enhancer but a differentiator in markets where multiple homes compete for attention.

What This Means for Northern California Homeowners

For homeowners in Solano, Napa, and Sacramento counties, the data suggests:

• Solar installations increase home resale value in measurable ways

• Battery storage systems may enhance resale appeal further

• Buyers are increasingly educated about long-term cost savings

• Solar homes may sell faster than comparable properties

These trends reflect broad market acceptance of solar as a valuable home improvement—not just an energy-saving upgrade.
