Commonwealth Solar Hot Water (Gov't/Non-Profit) - FAQ


How much will my rebate be?

Government and non-profit entities are eligible for base rebates covering 65% of project costs. The system may also be eligible to receive additional funding (“adders”) which increase the amount of the rebate. For small non-profit or government buildings installing eight or fewer solar hot water collectors, please read the Small-Scale Program Manual for rebate adder details. For large non-profit or government buildings installing more than eight collectors, please read the Commercial-Scale Program Manual for rebate adder details.

Why isn’t everyone in Massachusetts eligible for this rebate program?

Projects receiving rebates through MassCEC must be located in a utility territory that contributes funding to the Renewable Energy Trust (RET), which includes communities served by investor owned electric utility companies or a participating municipal lighting plant

What is an MLP and where are they?

MLP stands for “municipal light plant” and refers to communities who are serviced by a publicly owned local utility instead of an investor-owned electric company, such as National Grid or Eversource. Some of these MLP communities contribute to the RET, which is the original source of our funding for rebates. We are unable to provide rebates to MLP communities that do not contribute to the RET.
