Community solar for CMP customers.
Every CMP household in Maine can share in the state's community solar program. Credits get applied to the CMP bill you already pay — you keep 15% of the credit value as savings. No panels, no fees, renters welcome.

Fair question. There isn't one — here's how it works for Maine households, in plain English.
Where the discount comes from
The state's clean energy programs fund local solar farms that supply the same grid Maine already runs on. Join, and you're allocated a share of a farm's output — its credits show up on your CMP bill monthly.
What changes for you
Honestly? Just the total. Same CMP service, same wires, same reliability. No panels, no home visits, no equipment. You keep 15% of your credit value as savings.
How enrollment works
Enrollment is with Ampion, a public benefit corporation that's been running solar programs across the country since the state programs opened up. You sign up online, nothing gets installed at your home, and credits appear on your existing bill.
Questions Maine neighbors ask
Is this a government program?
The savings come through Maine's state-supported clean energy programs, but enrollment is with Ampion Renewable Energy, a public benefit corporation — not a government agency. Your CMP service stays exactly the same.
Does it cost anything to join?
No sign-up fees, deposits, equipment, or installation costs. Nothing is installed at your home and there's nothing to buy.
How much can I save on my CMP bill?
Most households keep 15% of their monthly credit value as savings.
I rent in Maine. Can I still join?
Yes. Your share lives at a solar farm, not your building, so renters qualify the same as homeowners — no landlord involvement needed.
Will my lights or service change?
No. Same CMP delivery, same wires, same reliability. The only change is credits appearing on your bill.
