Solar Panels and Home Value: The $79K Claim Explained

You’ve probably seen the headline circulating this week: “Solar panels can increase your home’s value by up to $79,000.” It’s a striking number, and I want to break down what it actually means — because the real story is more nuanced and, depending on where you live, potentially more relevant to your financial decision-making than the headline suggests.

Where the $79,000 Figure Comes From

The figure comes from EnergySage’s analysis of Zillow data and NREL (National Renewable Energy Laboratory) research on the solar premium in real estate markets. The methodology typically looks at comparable home sales with and without solar in the same markets, controlling for home size, age, and other variables.

The $79,000 number represents the high end of the range — what solar adds to home value in the most favorable markets. The national average from the most commonly cited NREL study is closer to a 4.1% increase in sale price for homes with solar.

On a $500,000 home, 4.1% is $20,500 in additional value. On a $750,000 home in a premium market, that same percentage gets you closer to the headline numbers. The $79,000 figure appears to reflect high-value homes in strong solar markets — California, Massachusetts, New York — where electricity rates are high and solar adoption is widespread enough that buyers understand and value it.

Why Solar Adds Value to Homes

The mechanism behind solar’s home value premium is straightforward: buyers are willing to pay for lower operating costs. A home that produces most of its own electricity has lower monthly ownership costs than an identical home without solar — and buyers price that in.

The NREL study found that buyers were willing to pay approximately $15,000 more per $1,000 in annual electricity savings that a solar installation provided. That’s a 15x multiplier on annual utility savings, which works out to roughly the value of 15 years of electricity bill reduction.

This actually understates the real value in current markets, because electricity rates have been rising 3–5% annually. A solar system that saves you $1,500/year today will likely save you considerably more in years 10, 15, and 20 as grid electricity becomes more expensive.

The Critical Variable: Owned vs. Leased

Here’s where the nuance really matters. The home value premium from solar applies primarily — sometimes exclusively — to owned solar systems. Solar leases and PPAs (power purchase agreements) are a more complicated story.

When you lease solar panels, you don’t own them — a solar company does. You’re essentially paying that company for the electricity the panels produce, typically at a rate that’s lower than grid electricity. When you sell the home, the lease transfers to the new buyer, who has to qualify and agree to take over the lease payments.

This can actually complicate or slow down home sales. Many buyers don’t want to assume a solar lease, even if it saves them money, because it’s an additional financial obligation they need to get approved for and understand. Real estate agents in high-solar markets will tell you that a leased system on a home is a much more complicated selling situation than an owned system.

If adding home value is part of your solar calculus, buy your system outright or finance it with a home equity loan — don’t lease. The premium is in ownership.

Market Variability: Where the Premium Is Real

The solar home value premium is real but not uniform. It’s strongest in markets where:

• Electricity rates are high. States like California, Hawaii, Massachusetts, Connecticut, and New York — where residential electricity often runs $0.20–$0.35/kWh — show the strongest premiums, because the annual savings are larger.
• Solar adoption is widespread enough that buyers understand it. In markets where most buyers have never thought about rooftop solar, they may not know how to value it. In markets where neighbors all have solar, buyers absolutely know what they’re looking at.
• The system is sized appropriately for the home. An oversized system that produces far more than the home uses has diminishing returns on home value — buyers don’t pay proportionally more for excess production.

In lower electricity-rate markets in the Southeast or Mountain West, the premium exists but is smaller. If you’re in Georgia paying $0.12/kWh, your solar system adds less home value than the same system in Connecticut at $0.27/kWh — simply because the annual savings are smaller.

How to Think About This in Your Decision

Here’s how I’d frame the home value piece in a real solar decision:

Don’t buy solar primarily for the home value premium. Buy solar for the energy cost savings and energy independence — those are the primary financial benefits. The home value increase is a bonus, not the lead reason.

Do factor it into your ROI calculation. Most solar ROI analyses focus only on energy savings. If you add a realistic home value premium — say, 3–4% on your home’s current value — your effective return on investment improves meaningfully. On a $400,000 home, a 3.5% premium is $14,000 in additional home equity that you could capture at sale.

Consider your time horizon. If you plan to sell in two years, you may not capture the full home value premium, and you definitely won’t have recouped installation costs through energy savings. Solar makes the most financial sense for people who plan to stay in their home for at least 5–7 years.

Get a good energy monitoring setup so you can document your system’s performance to buyers. When you do sell, being able to show prospective buyers actual production data — “this system produced X kWh last year, saving us $Y in electricity costs” — makes the value concrete and negotiable. A smart energy monitor that logs historical production data is worth the investment for this reason alone.

The Property Tax Question

One important caveat: in most states, solar installations are exempt from property tax assessment increases. Many states have passed solar property tax exemptions specifically so that homeowners don’t face a tax penalty for installing solar even though it increases their home’s market value. As of 2026, over 30 states have solar property tax exemptions in place.

Check your state’s rules before installing. If you’re in a state without this exemption, the $15,000–$20,000 in added home value from solar could result in a few hundred dollars per year in additional property taxes — worth knowing about, though usually not a deal-breaker.

Bottom Line

The $79,000 solar home value headline is real but represents the top of the range in premium markets with high-value homes and high electricity rates. For most homeowners, the realistic expectation is a 3–5% increase in home value — which on a $300,000–$500,000 home means $9,000–$25,000 in added equity.

That’s a meaningful bonus on top of the energy cost savings, the energy independence benefits, and the potential tax credits. Just make sure you own your system (don’t lease it), document your production, and factor your local electricity rates and market into any estimate.

The numbers work. They just don’t always work as dramatically as the headline suggests.
