How Maine works
Why the number is what it is
Maine is deregulated. The Public Utilities Commission sets the Standard Offer supply rate annually on January 1 through a competitive bid, and utilities bill it without profiting from it. Central Maine Power serves most of the south and centre; Versant Power serves the north and east.
Maine electricity rates rose 22.6% in the twelve months to August 2026 — the steepest increase of any state in the country. Maine sits at the end of New England's gas pipeline system, so winter capacity constraints hit wholesale prices hard.
The honest cost picture
Two ways to pay for solar
If you buy the system you own the equipment, keep any renewable credits, and carry maintenance. If you use a PPA it is $0 upfront — we install and own the system, you buy the power it produces, and you only pay for what it actually generates.
The residential federal tax credit (25D) ended for systems purchased after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional.
