Why can't I buy plug-in solar in New York, Maine or Vermont?

Because those three states require whole-system certification, and our kits do not carry it yet. A plug-in solar kit is assembled from separately certified parts: panels and a microinverter that plug into a standard outlet. Our components are individually certified, but what New York, Maine and Vermont ask for is different: certification of the assembled system as a single unit, under UL 3700 or a comparable standard. Until our kit holds that, we will not ship there. We ship to the other 47 states.

This is a certification question, not a legality question. For where plug-in solar stands state by state, see our guide: Is Plug-In Solar Legal? A 2026 State-by-State Overview.

Is plug-in solar illegal in those states?

No. The requirement is a standard the product must meet, not a prohibition on the category. Our kits do not currently meet it, so we do not sell them there.

What is UL 3700?

A safety standard written specifically for plug-in solar systems as complete units, rather than for the panel and inverter separately. Certification under it is still working its way through the industry.

Can I join as a member if I live there?

Yes. Membership is separate from buying a kit, and members in those states get the same voice in the campaign to change the rules, plus the discount for whenever a kit becomes available to them.

Will this change?

It changes when certified systems reach the market or when state requirements are revised. Both are moving. Check your state page for the current position rather than relying on this post.
