Do solar panels increase home value?

Owned solar: yes, measurably

Multiple studies, including work from Lawrence Berkeley National Laboratory and analyses by Zillow, have found that homes with owned solar sell for a premium over comparable homes without it. The exact figure varies by market, but a common finding is a resale bump in the ballpark of3-4% of home value, or roughly what the system is worth as a bill-reducing asset. Buyers are paying for lower future electricity bills, and appraisers increasingly recognise that.

Why owned solar adds value:

• Lower running costs transfer to the new owner, a tangible, ongoing benefit.
• No monthly payment attached, so the value is unencumbered.
• Newer systems with transferable warranties are the most valuable; a 15-year-old array less so.

Leased or PPA solar: it's complicated

A leased system or one on a PPA is owned by a third party, so it doesn't add to your home's value the way owned solar does, and it can actually complicate a sale. The buyer has to be willing to take over the lease/PPA contract (a credit check and paperwork), or you have to buy it out first. Some sales stall over exactly this. It's not a dealbreaker, but it's a very different situation from owning.

Financed (loan) solar

If you financed with a solar loan, you own the panels, good for value, but the outstanding loan is a lien you'll typically need to pay off from the sale proceeds. The home still shows the value of the owned system; you just settle the balance at closing like any other secured loan.

What actually protects the value

• Own it, don't lease it, if resale value matters to you.
• Keep the paperwork, install docs, warranties, and production history reassure buyers and appraisers.
• Use quality equipment and a reputable installer; an orphaned system from a defunct company is worth less.
• Right-size it. A system matched to the home's usage is more appealing than an oversized one on a poor export tariff.

The bottom line: owned solar is generally an asset at resale, not a liability. If you're weighing lease vs. buy partly for that reason, the ownership comparison is here.
