Enter your bill and we’ll size the array that would cover it, and show the gross value of that production at your rate. It does not net off the customer charge, taxes or what you would still draw at night — for that, use the bill savings calculator. Nothing is sent anywhere; this runs in your browser.
An estimate from your own numbers, not a quote, and not a savings figure. It assumes 400 W panels, an 80% system derate and no roof constraints. Your real number depends on orientation, roof area and your utility’s export credit. Savings are not guaranteed.

Why the number is what it is
Eversource raised basic service 5.01% on February 1, 2026 — from 14.884¢ to 15.629¢ — then another 10.8% on August 1, to 17.32¢. Massachusetts law fixes those reset dates.
Eversource attributes the increase to market conditions: an unusually cold winter driving gas demand, and international instability straining energy markets. The utility earns no profit on the supply charge itself.
Infrastructure upgrades and clean energy commitments are recovered through rates over time.
The honest cost picture
You own the equipment, you keep any renewable energy credits, and you carry the maintenance responsibility. Installed pricing varies by roof, shading and system size.
$0 upfront. We install and own the system; you buy the power it produces at a rate set in your agreement, and you only pay for what it actually generates. The system owner carries maintenance for the life of the agreement.

You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. If you buy a system today as a homeowner, you cannot claim that credit. 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 about your situation.
Going solar with Eversource
When your panels make more power than your home is using, the extra flows onto Eversource’s grid and is credited on your Eversource bill under Massachusetts’s net metering rules. How much each exported kilowatt-hour is worth is set by those rules, and it is one of the biggest factors in how your system should be sized. How net metering works in Massachusetts.
Eversource connects home solar systems to its grid and credits the power you send back, but it does not install panels. State incentives are covered in our Massachusetts solar incentives guide, and SolarAmerica handles the Eversource interconnection application for you.
There is no separate sign-up. It is set up as part of the interconnection application your installer files with Eversource before your system is turned on, and SolarAmerica files it for you.

Eversource questions
Only if you are on basic service. About 26.6% of Massachusetts customers were as of March 2026; the rest are on municipal aggregation or competitive supply. Check the supply line on your bill.
Massachusetts law requires supply rates to reset in February and August each year. Both 2026 resets moved up — 5.01% in February and 10.8% in August.
Yes. Panels generate from light rather than heat and are more efficient when cold. At roughly 30 cents per kilowatt-hour, the economics here beat plenty of sunnier states.
About 60 seconds. No cost, no obligation, and we will tell you if solar does not make sense for your home.
