How Solar Panels Boost Your Home's Resale Value

My neighbor sold her house last spring and got $31,000 more than comparable homes on her street. The only meaningful difference? A paid-off 9.2 kW solar system she’d installed four years earlier. I’ve seen this play out dozens of times, and I’ve also seen the opposite: sellers who couldn’t recoup a dime of what they paid because the system was leased, or because they were in a market where buyers just didn’t care. So before anyone tells you “solar definitely adds value,” let me give you the actual picture.

The Numbers Are Real, But They’re Not Universal

Scenario	System Cost (Before Incentives)	Federal Tax Credit (30%)	Cost After Incentive	Typical Home Sale Premium	Net Outcome
Owned 7.5 kW System	$25,000-$35,000	$7,500-$10,500	$14,500-$27,500	~$30,000	Break-even to positive
Owned 8 kW System (Sunny Market)	$25,000-$35,000	$7,500-$10,500	$14,500-$27,500	Varies by market	Positive in high-rate states
Leased System	$0 upfront	N/A	$100-$200/month obligation	Little to none	Negative (buyout $10k-$20k)
PPA System	$0 upfront	N/A	Per-kWh payments	Little to none	Negative (buyer reluctance)

Here’s the headline figure: a Lawrence Berkeley National Laboratory study that’s been widely cited by the Solar Energy Industries Association (SEIA) found that buyers paid a premium of about $4 per watt of solar capacity for owned systems. On a 7.5 kW system, that’s roughly $30,000. For most homeowners, that’s close to or exceeds what they originally paid after the federal tax credit.

EnergySage’s market data consistently shows the national average solar installation running between $25,000 and $35,000 before incentives, and the 30% federal Investment Tax Credit currently brings that cost down meaningfully. So in a lot of scenarios, the math actually works: you install, you save on electricity, you sell at a premium, and you come out ahead. I’ve personally helped clients model this out, and it’s genuinely one of the better home improvement investments in the right conditions.

But those conditions matter enormously. More on that in a minute.

This is where most people get confused, because the appraisal process for solar still isn’t as consistent as it should be.

Appraisers are supposed to use something called the income approach or the cost approach when valuing solar. The income approach calculates the present value of future electricity savings. The cost approach looks at what it would cost to replace the system, depreciated for age. In practice, appraisers in solar-saturated markets like California, Arizona, and Colorado tend to be more comfortable with these methods. In markets where solar is still uncommon, like parts of the Midwest or rural Northeast, you’ll often find appraisers simply ignoring the system entirely or giving it token value.

I’ve talked to homeowners in Ohio who were stunned when their appraiser valued a $28,000 solar system at essentially zero. It’s not that the appraiser was incompetent. It’s that there weren’t enough comparable solar home sales in the area to anchor the valuation. No comps, no data. No data, no value added.

If you’re in a market like this and you’re buying or selling soon, it’s worth requesting an appraiser with specific experience in renewable energy. The Appraisal Institute even offers a green energy addendum form (Form 820.05) that trained appraisers use. Most homeowners have never heard of this. Most real estate agents haven’t either.

The Lease Problem Is Still Killing Deals

The Case for Solar Being Undervalued at Sale (And Why I Think It Is)

Here’s the contrarian take: I think solar is routinely undervalued in home sales, and most sellers leave money on the table because they don’t know how to present the asset.

A typical 8 kW system in a sunny market produces around 11,000 to 12,000 kilowatt-hours per year. At the national average residential electricity rate today (around $0.17/kWh), that’s $1,870 to $2,040 in annual savings. Over 25 years, even discounting for rate increases and modest panel degradation, that’s a six-figure asset in present-value terms. But sellers almost never present it that way to buyers.

What most people don’t realize is that the framing at sale matters. Sellers who show buyers their utility bills, their monitoring app data, and a projected savings model move homes faster and at better prices than sellers who just mention “solar panels included” in the listing. I’ve seen a seller use a Sense Home Energy Monitor to generate a compelling year-over-year savings report that they literally printed and left on the kitchen counter during open houses. (Disclosure: this site may earn a commission on purchases made through Amazon links.) Corny? Maybe. Effective? Absolutely.

Your installer should be able to pull production data from the system’s inverter. If you have an older system without monitoring, a clamp-on energy monitor can fill that gap. Make the invisible visible.

Does Location Change Everything?

Yes, dramatically. In California, Hawaii, Massachusetts, and New Jersey, solar premiums are well-documented and relatively predictable. These markets have high electricity rates, strong net metering policies, and buyers who understand what they’re getting. In states with very low electricity costs, like Louisiana or Idaho, the economic case for solar is weaker, and the home value story is weaker with it.

Climate isn’t just about sunshine, either. It’s about the utility environment. A state with strong net metering (where you get credited for power you send back to the grid) produces more savings, which translates to more value. States that have rolled back net metering policies create real headaches for buyers trying to project future savings. This is genuinely one of the most important and least-discussed factors.

Frequently Asked Questions

Does solar always increase home value?

No. The increase is most reliable for owned systems in high-electricity-cost markets with strong solar adoption. Leased systems frequently add no value and can complicate sales. Rural markets and states with low electricity rates see the smallest premiums.

How much does solar increase home value?

The most-cited research puts it at roughly $4 per watt of installed capacity for owned systems, which translates to about $20,000 to $30,000 for a typical residential system. Your actual result depends on location, system age, local market conditions, and whether comparable solar homes have sold nearby.

Does a solar lease transfer to the new owner?

Usually yes, but it requires the buyer to qualify for and agree to take over the lease. Many buyers decline, which can slow or kill the sale. Some sellers buy out the lease before listing to avoid the issue entirely.

Will my home sell faster with solar?

In markets where solar is common and well understood, yes. A 2019 study from Zillow found solar homes sold about 20% faster than comparable non-solar homes. In markets where solar is still unusual, the effect is weaker and less predictable.

Do I need to disclose solar panels when selling?

In most states, yes. You’ll typically need to disclose whether the system is owned or leased, the terms of any third-party agreement, and any known defects. Check your state’s disclosure requirements; failing to disclose a lease can expose you to legal liability.

The bottom line is more nuanced than most solar installers will admit, but it’s genuinely good news for people who go in with clear eyes: own your system, document your savings, and sell in a market that values it. Do those three things and solar is one of the few home improvements that can pay you back twice.
