Is plug-in solar legal in Massachusetts?

What the Massachusetts bill says

• Size. No cap is settled.
• Safety listing. Not settled.
• Telling the utility. We have not confirmed a notice rule.

Both chambers passed different versions of an energy bill. A conference committee was appointed on 16 Jul 2026 and no later action is recorded. The House version has a 1,200 W cap. News reports say the Senate version lets people install up to 420 W without utility permission, but we have not read that text.

Where the bill stands

The House and Senate passed different versions and sent them to a conference committee. We cannot find any action since that was set up. A deal could still come, but we have no date for one, and we will not guess at what the final rules look like.

Until it becomes law, there is no state rule to follow. Do not read the numbers on this page as requirements.

Renters, condos and apartments

Nothing we have read about the bill in Massachusetts covers renters, landlords or condo associations, so we will not guess. Your lease and your landlord's rules still apply.

What it might save you

We have not put a Massachusetts savings figure on this page yet, because we have not finished checking the state electricity price and a solar output figure for Boston. Our calculator is the place to try your own numbers once the US version is up. The method is on the methodology page.

How Massachusetts compares

For a different picture, see Utah. Nothing here is settled, so the best use of your time now is to understand the product. How plug-in solar works covers it without any legal detail, and the alert list will tell you if Massachusetts moves.
