The Massachusetts Clean Energy Center (MassCEC) states that a two panel system for a 4-5 person family would cost about $8,000-$10,000. Residents can save more money on their system (the MassCEC estimates up to half the cost) with other state and federal incentives, such as the 30% federal renewable energy tax credit and Massachusetts' renewable energy tax credit and property tax exemption.
Residents must be an electric customer of NSTAR, National Grid, Unitil, Western Massachusetts Electric Company, or from Ashburnham, Templeton, Holden, Holyoke or Russell to qualify. The rebate program has $1 million and is funded through the MassCEC's Renewable Energy Trust.
In addition to the solar thermal rebates, MassCEC distributes residential rebates for solar electric panels and small wind.
