Massachusetts Solar Contract Checklist

Use this checklist before signing a solar agreement, or if you already have panels and something has gone wrong. For background, see Solar Panel Disputes in Massachusetts.

Before You Sign

• Confirm whether you will own the system, finance it, lease it, or buy power under a PPA.
• Get the total cost in writing, including financing charges, dealer fees, and any annual escalator.
• Ask for the contractor’s Home Improvement Contractor registration number and check it.
• Get production estimates in writing and ask whether there is a production guarantee.
• Ask who is responsible for roof penetrations and leaks, and for how long.
• Ask what happens if you sell the house, replace the roof, or move the system.
• Ask whether a UCC filing or lien will be recorded.
• Do not rely on tax-credit promises; confirm with your tax advisor.
• Do not sign on a tablet without reading every page; ask for a full copy.

Cancellation Rights

• Note the date you signed and any cancellation deadline stated in the contract.
• Cancel in writing, in the method the contract and law require, and keep proof of delivery.

After Installation

• Keep the permit, inspection sign-off, and interconnection approval.
• Download production data monthly and compare it to the estimate.
• Inspect the attic and ceilings after heavy rain and snowmelt.
• Report problems in writing and keep every response.

If Something Goes Wrong

• Gather the contract, financing or lease documents, proposals, and all communications.
• Photograph damage and get a roofer or electrician’s written assessment.
• Continue required payments unless a lawyer advises otherwise.
• Talk with a lawyer about Solar Contract and Sales Disputes, Solar Roof Leaks and Installation Defects, or Selling or Refinancing a Home With Solar.

Frequently Asked Questions

Is it too late to cancel if I already signed?

Possibly not. Statutory cancellation periods are short, usually a few business days, but other remedies may be available if you were misled or not given proper notice. Act quickly.

What should I ask before signing a solar contract?

Who will own the system, the total cost including financing and dealer fees, whether the contractor is registered, who handles roof penetrations and leaks, what happens when you sell or replace your roof, and how cancellation works.

Where can I report a solar company?

You can file a complaint with the Massachusetts Attorney General’s Office and, for home improvement contractor issues, with the Office of Consumer Affairs and Business Regulation. A complaint does not replace a lawyer’s review of your private claims.
