Solar Companies in Cambridge, Massachusetts
What Cambridge homeowners actually pay for power
Cambridge homeowners in Middlesex County are typically served by Eversource. Eversource customers pay about ~30¢ per kilowatt-hour all-in — supply plus delivery plus riders, not the supply rate on its own. That is the number that decides whether solar is worth it here, because every kilowatt-hour your roof produces is one you stop buying at that price.
The full breakdown is on our Eversource rate page. You can compare it against every other utility in the state on Massachusetts electric rates.
Why Massachusetts rates keep climbing
Every Massachusetts utility buys wholesale power through ISO New England. When capacity and energy prices rise there, they land on Eversource bills and on every other utility in the state at roughly the same time. Demand from data centers is arriving faster than new generation is being built, and that gap is what shows up on your bill — it is not something Eversource sets on its own.
Solar changes the arithmetic because it fixes part of your cost. A power purchase agreement in Cambridge means no upfront payment: we install and own the system, you buy the power it produces at a set rate, and you keep buying whatever you still need from Eversource.
What solar costs in Cambridge
There is no single number, and any site that gives you one without seeing your roof is guessing. What decides it is your usage, your roof orientation and shading, and the ~30¢ you pay Eversource today. If your roof does not work, we say so on the first call rather than after you sign.
$0-down options are available for qualifying Middlesex County homeowners. The federal residential purchase credit ended for systems bought after December 31, 2025, so anyone still advertising it is running an old ad. What remains in Massachusetts is net metering, and under a PPA the credit stays with the system owner rather than the homeowner.
Common questions from Cambridge homeowners
Who is my electric utility in Cambridge?
Most of Middlesex County is Eversource territory. Your bill names your utility at the top — if it does not match, call (832) 263-8055 and we will check your address against the service map.
Does solar still make sense now that the federal credit ended?
Under a PPA, yes. The credit belongs to the system owner, which is us, not you — that is what makes $0 down possible. For an outright purchase the math changed in 2026, and we will show you the honest version rather than the brochure version.
What happens if I sell my house?
A PPA transfers to the buyer. We handle the paperwork and the new owner takes over the same rate.
How long does an install take in Cambridge?
Installation is typically one to three days. Permits with your municipality and interconnection with Eversource take longer, and we handle both.

Solar Power in Cambridge, Massachusetts
Cambridge homeowners are increasingly going solar as electricity costs from Eversource climb and Massachusetts's incentives make the switch more worthwhile than ever. Every kilowatt-hour your roof produces is one you no longer buy at Eversource's rising rates — the foundation of solar's value in Cambridge.
Massachusetts homeowners can take advantage of the SMART program and net metering. The federal residential solar tax credit ended for systems purchased after December 31, 2025; current incentive availability depends on ownership structure, state programs, and current law. SolarAmerica does not provide tax advice.
Net metering credits the excess power your system sends back to the grid, so the energy your panels make on long summer days helps offset what you draw in winter. Solar also raises home resale value — and Massachusetts exempts solar from added sales and property tax.
Modern high-efficiency panels produce reliably in Cambridge's climate, and pairing them with battery storage keeps your home powered during outages.

Solar Incentives & Net Metering in Massachusetts
Massachusetts runs the SMART program (Solar Massachusetts Renewable Target), a production-based incentive for qualifying systems. The state also offers a residential renewable-energy income tax credit, net metering, and exemptions from sales and property tax tied to your solar system — strong reasons solar performs well against high Massachusetts rates. Net metering is what makes home solar pay off month to month: when your panels make more than you use, the surplus flows to the grid and you earn a bill credit; at night or on cloudy days you pull power back and those credits offset it — for a lower, more predictable monthly energy cost.
