Solar panels on a house can be owned outright, financed or covered by an agreement with another party. Those arrangements create different obligations for a buyer. Begin by identifying who owns the equipment and the exact contract involved before assuming the panels simply reduce the future electric bill.
Which agreement should you obtain?
Massachusetts Clean Energy Center advises buyers and sellers to review the arrangement, including a lease or power-purchase agreement where applicable. Request the complete contract, amendments, payment schedule and transfer provisions. Ask what consent, credit review, buyout or other steps may be required by the actual terms. The seller's description of the monthly saving is not a substitute for this review. Keep equipment ownership and electricity purchasing as distinct questions.

What should the performance and maintenance review include?
Ask for available production records, system age, warranties, service history and responsibility for repairs. Clarify what happens if the roof needs work and who handles removal or reinstallation. Compare production and bills over identified periods rather than assuming one favorable month represents the year. The local heating-fuel context below does not predict the home's electric load or solar output. A building's actual consumption, equipment and occupancy determine the financial comparison.
How does the agreement affect the transaction?
Provide the relevant documents to the lender, insurer and legal adviser early. Confirm the steps required before closing and identify any unresolved charges or obligations. Include continuing contract payments alongside electricity purchases, taxes, insurance and maintenance in the household budget. Do not count the same benefit twice by subtracting an assumed saving while omitting the payment that produces it. The buyer needs a clear description of what transfers with the property and what remains payable after the purchase.

What These Columns Mean
- Town
- Municipality; follow its record below for the full data and address check.
- Single-family Assessment
- Median assessed value of single-family parcels. This is a tax-roll statistic, not an asking price, appraisal or median sale price. Assessment years are identified in the sources.
- Annual Tax Illustration
- The published residential rate applied to the town's median single-family assessment, including the recorded community preservation surcharge and its general first-value exemption where adopted. Individual exemptions, special assessments and a future reassessment can change an actual bill.
- Most Common Heating Fuel
- Largest publishable household heating-fuel category in the survey. It describes the town's mix, not the equipment, fuel bills or service options at a specific home.

What should you check next?
- Identify equipment ownership and obtain the complete financing, lease or power-purchase documents.
- Review production, maintenance, warranties and roof-work responsibilities using dated records.
- Confirm transfer requirements and include all continuing payments in the lender review and household budget.
Keep the address, document date and source alongside each answer. If records disagree, identify which period and property each describes before treating the difference as a change. A missing result leaves a question open; it does not establish that a property has no problem or no cost.
Where can you continue the comparison?
- Understanding electric service context
- Planning another home-energy change
- Reconciling transaction obligations
