Solar Rebate program


As part of the Municipal Light Solar Rebate Program (MLP Solar Program), the Wakefield Gas & Light Department has pledged funds, which the Department of Energy Resources (DOER) will match. Approved projects will receive one-time rebates of up to $1.20 per watt off the cost of the installed system and awards will be dispensed on a first-come, first-serve basis while program funds last or on December 30th; whichever comes first. With the exception of projects with contracts executed prior to May 13, 2019, any installation work done prior to rebate approval is done at your own risk.

NOTE: Solar projects should not be started until fully approved.

A valid email address must be provided for DOER to contact the customer. If customer does not have an email address, customer should designate someone to be a contact for the following three entities: the DOER, WMGLD and MMWEC.


  • Program is available to residential and commercial customers in good standing
  • System must be owned by the customer
  • System must be installed between 90° and 270°
  • System size is capped at 10kW DC for residential systems and 25 kW DC for commercial systems (Systems larger than this can be
    installed with permission from WMGLD but will not be eligible for any rebate funds)
  • Shade reports must show annual access is at least 80%

Shade Analysis Requirements

Per the DOER’s Program manual, the following shade analysis will be accepted:

  • Solmetric SunEye
  • Solar Pathfinder
  • Wiley ASSET Software
  • Aurora software with LIDAR data available
  • Bright Harvest

    business days of receipt of application and all required documents by WMGLD
  3. WMGLD’s Interconnection Application and Interconnection & Solar Net Metering Agreement, both signed by the
