Battery backup is mandatory
in Eversource territory.
Eversource does not credit the power you send back at the rate it charges you to take it.
That does not make solar a bad idea in Eversource territory. It changes what you should build. When exports are worth a fraction of retail the credit stops being the return, and the job becomes using more of your own production inside the house, which usually means a larger array than a one for one utility would need.
Sizing is where that gets decided, so ask about it directly. New Hampshire limits residential and small commercial systems to 100 kW AC, far above what a house needs, and credits at about 85% of retail. The binding constraint is your own usage, not the rule. Eversource sets its own limits. Ask Eversource what it allows before you accept that a bigger system is off the table.
A battery then does two separate jobs. It moves daytime production into the evening so you use it instead of selling it, and it keeps the house running when the grid goes down. That second job is not a bonus. Panels on their own shut off in an outage, by design, so a roof full of them powers nothing during a storm. That is the part we will not refer around.
So we treat it as a requirement, not an upgrade. We will not refer you for a panels-only system in Eversource territory, and you should be skeptical of anyone who quotes you one without raising storage first.

What your installer should be telling you
Check the three components against your own bill, and confirm the current values with the utility. The formula is fixed; the components underneath it are not.
Applying to Eversource
What Eversource itself requires, as distinct from what the state rule requires. Read from its own published guidelines on the date shown.
- The credit is a published formula
- Under Docket DE 16-576 the residential net metering credit is 100% of the supply component, plus 100% of transmission, plus 25% of distribution. You can check it against your own bill line by line.
- That comes out around 84 to 85% of retail
- Reported values are about 21 cents per kWh at Eversource against a roughly 25 cent retail rate, and about 22 cents at Unitil against roughly 26 cents.
- It is locked until 1 January 2041
- The formula holds through that date, so a system connected today has a defined credit structure for fifteen years and more. Very few states offer that much certainty.
- 100 kW AC is the residential ceiling
- Far above what a house needs, so New Hampshire’s rule is not what limits your system.
- Ask for the three components separately
- Because the credit is built from supply, transmission and distribution, you can verify a quote by reading those three lines off your own bill. Very few states let you check the arithmetic yourself.

Eversource net metering questions
- Does Eversource offer one for one net metering?
- No. The residential net metering credit is 100% of supply, 100% of transmission and 25% of distribution, roughly 84 to 85% of the retail rate, locked through 1 January 2041.
- What does Eversource pay for power sent back to the grid?
- Supply plus transmission plus a quarter of distribution. Credits carry against the bill.
- Do I need a battery with Eversource?
- Yes, and we treat it as mandatory. Because Eversource does not credit exports one for one, the return has to come from using your own production rather than selling it, which after dark means storage and usually a larger array than a one for one utility would need. The other half is backup: panels alone shut off in an outage, so a battery is what keeps the house running in a storm. We do not refer panels-only systems in Eversource territory. This is our referral policy, not a legal or utility requirement.
- How do I find my Eversource bill?
- Sign in at eversource.com. Open My Account, then Billing. Open the latest bill and save the PDF. Or screenshot the summary page. If you cannot get to it, a rough guess at your average monthly amount is enough to start.
- What is the catch with Eversource?
- Check the three components against your own bill, and confirm the current values with the utility. The formula is fixed; the components underneath it are not.

These are real companies operating in Eversource territory, ordered by reviews, years trading and BBB grade. None of them pays us for placement. Pick the one you want and we will call you to arrange it.
Ordering combines three things we read from primary sources: Google review count and rating, years trading taken from the company’s Better Business Bureau profile rather than its own marketing, and its BBB letter grade. BBB accreditation is shown but never scored, because it is a paid membership rather than a mark of quality.
Check any contractor license yourself at the state register. Do that before you sign anything, with any company, including ours.
