Net metering in Maine, provider by provider.
Every provider in the state, and every figure below read from the published tariff or interconnection document rather than a comparison site. Some credit you the full retail rate for the power you send back. Most do not, and that difference is the whole reason this page exists.
Meter reading falling from 41926 to 41773 kilowatt hours. A 550 kilowatt hour month against 703 kilowatt hours produced leaves 0 kilowatt hours billed and 153 banked for next month, so the energy charge falls from $162.75 to $0.00 at 29.59 cents per kilowatt hour.
Maine average household use, 550 kWh a month, at the current published residential price of 29.59¢ per kWh. Your utility still bills a fixed monthly customer charge that no system offsets, so this is the energy part of the bill, which is the part that goes away.

Residential Net Energy Billing credits exported kilowatt hours one for one against the kilowatt hours you buy, so each is worth your delivery plus supply price: about 24.7 cents at CMP and about 30 cents at Versant on the 2026 standard offer. Unused credits expire after twelve months.

Net metering in Maine: the questions people ask
- Does Maine have net metering?
- Residential Net Energy Billing credits exported kilowatt hours one for one against the kilowatt hours you buy, so each is worth your delivery plus supply price: about 24.7 cents at CMP and about 30 cents at Versant on the 2026 standard offer. Unused credits expire after twelve months.
- What is the solar buyback rate in Maine?
- It is set utility by utility, not by the state. How the 2 providers we list in Maine credit the power you export: 2 at the full retail rate. Each one’s own page gives its figure and the date we read it.
- Is solar worth it in Maine in 2026?
- It depends mostly on what your utility pays for the power you export, because the 30% federal credit ended for systems completed after 31 December 2025. Maine homes use about 550 kWh a month at an average of 29.59 cents per kWh, according to the U.S. Energy Information Administration. Where exports are credited at the full retail rate, each kilowatt hour your panels send back is worth about that much; where they are credited below retail, size the system to what you use while the sun is up. Check your own utility on this page before you get a quote for solar panels.
- Is there a solar tax credit in Maine in 2026?
- Not a federal one. The 30% federal credit, IRC Section 25D, ended for systems completed after 31 December 2025, and a deposit paid in 2025 does not preserve it. Anyone still quoting it is working from an old script. Any incentive left in Maine comes from the state or your utility, and what your utility pays for exported power is now most of the financial case.
- Which providers does the Maine rule cover?
