Merrimac Municipal Light Department (MMLD) customers who want to install solar panels for home energy use can now apply for a generous incentive through the MLP Solar Program. The MMLD has pledged $25,000, which the Department of Energy Resources (DOER) will match, for a potential total of $50,000 in program funds. The MLP Solar Program will award $1.20 per watt for approved projects, with the MMLD and the DOER both providing a matching contribution of $.60. Awards will be dispensed on a first come, first served basis to solar projects that meet specific requirements.

The MLP Solar Program provides an up-front award, making it different from the recently-expired Solar Renewable Energy Credit (SREC) program. Until December of 2018, SREC program participants received their award quarterly, spread over 10 years. Municipal Light Plants, such as the MMLD have worked with the DOER and our energy service agency, Energy New England (ENE) to develop the immediate payout rather than a payout over time. The MMLD is participating in this remarkable incentive program to make solar technology more affordable for our customers to adopt robust renewable energy sources.

Program Highlights

  • Provides $1.20 per watt of installed solar production
    For example: Systems sized for 3kW of solar energy product (direct current) will be eligible for a $3,600 rebate.
  • Rebates will equal no more than 1/2 the installed cost of any system.
  • Participating customers will also have financing options available through the Mass Solar Loan program, with low-interest, fixed rates and support for income-qualified residents.
  • Only customers with renewable generation systems approved by the MMLD will qualify to receive the rebate.
