Solar panels can be a fantastic upgrade—or a complicated liability—depending on how they were installed, financed, and documented. I’ve seen both sides of that equation play out at closing tables across numerous states here in the US.

​

If you’re considering purchasing a home with solar, this is not a situation where you want to “figure it out later.” Solar intersects with real estate contracts, mortgages, title insurance, appraisals, inspections, and long-term ownership costs. Miss one detail, and it can derail a deal or create surprises after you move in.

​

That’s why it’s critical to work with a Realtor who has been specifically trained to handle solar, not one who treats it like a cosmetic feature.  Understanding what can go wrong protects buyers from 

​

Here are the ten questions every buyer should ask—and understand—before committing to a solar-powered home.

​

 

1.  Is the solar system owned by the seller or by a third party?

​

This is the single most important question. Some systems are fully owned. Others are leased or financed through a power purchase agreement (PPA). The answer affects everything that follows, from monthly costs to mortgage approval.

 

2.  If there are payments, how long do they last?

​

Solar agreements often run 15, 20, or even 25 years. You need to know exactly how much time is left and whether those terms align with your long-term plans for the home.

 

3.  How are payments made?

​

Solar payments may be billed monthly, annually, or escalated over time. In some cases, homeowners still receive an electric bill and a solar bill. Understanding the payment structure prevents unpleasant surprises after closing.

​

 

4.  Will I have additional monthly costs beyond my utility bill?

​

Solar doesn’t always replace your electric bill entirely. Depending on system size, utility rules, and usage, you may still have a balance with the power company. Ask for real numbers, not estimates.

​

 

5. Does this home cost more or less per month than a comparable home without solar?

​

Solar should be evaluated like any other financial component of the home. Compare total monthly housing costs—including solar—to similar non-solar properties. Savings are not automatic.

 

6. Will assuming a solar agreement affect my mortgage approval?

​

Yes, it can. Some solar obligations are treated as debt. Others impact debt-to-income ratios or underwriting decisions. This is where coordination between your Realtor and mortgage professional matters.

 

7.  Will anything related to the solar appear on the title?

​

Certain solar agreements involve liens, UCC filings, or other title considerations. These must be identified early to ensure you can take clear ownership of the property.

​

 

8. What is the condition of the roof?

​

Solar panels are only as good as the roof beneath them. Was the roof replaced before installation? How old is it now? Removing and reinstalling panels later can be costly.

​

9. Are there warranties that need to be transferred?

​

Panels, inverters, and installation work often carry separate warranties. Not all warranties transfer automatically. You’ll want written confirmation of what protection carries over to you as the new owner.

​

 

10. How do we verify that the system is working?

​

Ask for production data, monitoring access, and documentation. You should know how to confirm the system is producing power—and what steps to take if it isn’t.

​

 

Final Thought

​

Solar isn’t a deal-breaker—but it is a deal detail.

When handled correctly, solar can be a benefit. When misunderstood, it can complicate financing, delay closings, or create long-term cost issues for buyers who thought they were getting a bargain.

​

This is why working with a Realtor trained specifically to handle solar transactions matters. Solar lives at the intersection of real estate, lending, title, inspections, and consumer protection—and it deserves to be treated with that level of care.

​

Education first. Questions second. Decisions last.

​

That’s how you protect yourself when buying a solar-powered home.
