What Eversource solar incentives am I eligible for?
Eversource provide net metering and a “SMART” incentive to their solar customers in Boston. The combination of these two incentives means solar systems pay for themselves in as little as 3-4 years.
How does the new SMART program work?
SMART stands for Solar Massachusetts Renewable Target and is basically a plan for the state to install 1,600MW of additional solar. The incentive works by forcing utilities to pay a credit to their solar customers for every KiloWatt hour of solar generation.
The exact incentive amount hasn’t been published yet however, it has been confirmed that applicants will be able to apply later this year. The incentive works by valuing the power production at a certain incentive rate subtracted by the retail price. This means that if the top tier incentive were to be $0.35/kWh and the rate you pay for power is $0.12/kWh Eversource would have to pay you $0.23/kWh for each kWh your solar system produces.
You receive these credits alongside your net metering returns.
Does Massachusetts offer a state tax credit?
Massachusetts provides a tax credit for 15% of the net cost of you solar system (cost after all other incentives). The incentive is capped at $1,000.

Net Metering Broken Down
What is net metering and does it affect my investment?
At times your solar system will produce more energy than what is needed in your home, this excess generation is exported to the grid and purchased by Eversource, net metering requires Eversource to credit you at the retail power rate for each kWh your solar system sends them.
What if my solar system exports more energy than I consume?
This is likely to happen in sunny months where your energy usage is low. Remaining credit at the end of the month is simply rolled over to the next bill still at retail value indefinitely.
