Solar in Massachusetts.
Lower the bill month after month. Massachusetts still credits what you send back to the grid — Helio sizes the array to how you actually live.
Massachusetts
What makes Massachusetts different.
Typical homes here see about $0.29 / kWh and 1,210 kWh per kW per year. We size the system to your bill — then confirm it on the roof.
Eversource, National Grid, and Unitil each have their own net-metering class and cap. The prelim uses your blended retail rate. The visit confirms the actual tariff and whether a SMART block is even open.
Residential solar equipment is sales-tax exempt. There is no Massachusetts income-tax credit that replaces 25D. The value is the bill, month after month.
- Local programs that may apply
Net metering
Retail-rate credits
Export credits offset the bill at (or near) retail, subject to your utility’s current net metering cap and class.
SMART (if block open)
Varies by block
Declining-block tariff. Many residential blocks are exhausted; Helio checks remaining capacity before we promise it.
Sales tax exemption
100%
Residential solar equipment is exempt from Massachusetts sales tax.
Massachusetts, specifically
What power has actually cost here.
Every savings figure on this site assumes your utility keeps raising its rate. So does every other company’s. The difference is that you can check ours — these are the federal government’s own published prices for Massachusetts, next to the number we model.
| Last 5 years (2019–2024) | 6.0% |
|---|---|
| Last 10 years (2014–2024) | 5.4% |
| Since 2005 (2005–2024) | 4.2% |
| What Helio assumes | 4.0% |
No single window is the truth, which is exactly why anyone showing you one number for the next twenty-five years — including us — is showing you an assumption. Ask any installer what your savings look like at today’s rate with no increase at all. How the money works runs that comparison.
Who you buy power from here
Eversource, National Grid, Unitil. Which one serves your address decides the tariff you can take and the credit you get for what the roof exports, so an advisor confirms it before anything is filed.
Who does the work
Crews dispatch from Boston. Licensed in Massachusetts as 213657 — public record, worth looking up before you let anyone on your roof.
