Solar Rebate Program

The Massachusetts Municipal Light Plant Solar Program allows residential customers of municipal light plants, such as SELCO, to apply for a rebate for the purchase, installation, and usage of PV solar panels on their homes. The program includes a rebate of $1.20 per watt up to 10kW of installed capacity and 50% of the installed cost (maximum rebate of $12,000). Eligible solar installations must be 25 kW or less, have less than 20% shading, and face between 90° (East) and 270° (West). An additional meter fee applies. Other restrictions may apply. Funding is available on a first-come first-serve basis.

Interested customers must obtain pre-approval from SELCO, then submit an application with the Massachusetts Municipal Wholesale Electric Company (MMWEC), SELCO's joint action agency. Applications may be submitted through December 30, 2020. See below for the application process. If you have questions regarding funding availability, please contact

  • Max. System Size 25 kW.

  • Max. 20% Shading

  • Must Face Between 90° (East) and 270° (West)

  • Rebate = $1.20 per watt up to a max of $12,000.00 (10kW of installed capacity)


PLEASE NOTE: There are limited remaining funds available for the SELCO solar rebate program. We are temporarily pausing acceptance of new solar rebate applications while we complete the rebate projects currently in-process. If your decision to move forward on your solar project is contingent on receiving the rebate, please indicate this on your SELCO Solar Interconnection Application so you can be placed on our wait list. Those on the wait list will be awarded any remaining rebate funding based on the order in which they applied through SELCO. 


To apply for the MLP Solar Rebate, please follow the steps below.

NOTE: Contractors/Homeowners should not begin construction until receiving a REBATE APPROVAL LETTER.

REBATE FUNDS will be issued to the applicant upon final completion, interconnection, and activation of your solar project. The CERTIFICATE OF COMPLETION issued by SELCO will provide confirmation that the project is complete and operational. This CERTIFICATE should be submitted to MMWEC to request release of your REBATE FUNDS.

1. SELCO Application

Solar FAQs

What is Net Metering?

Net metering is an agreement by which a customer with solar panels is allowed to transfer surplus power produced by their panels onto the grid.  That excess power is purchased by SELCO, resulting in a credit on their bill.  

Does SELCO offer Net Metering?

Yes.  SELCO has a residential net metering policy.  However, this policy is only applicable for projects up to a certain size and is only applied to panels owned by the customer.  This means projects constructed through panel leasing agreements and/or third-party power purchase agreements (PPAs) do not qualify for net metering and are not permissible under existing policy.


Effective 03/04/2016: All interconnect agreements submitted for net metering will be subject to future revisions of SELCO's net metering tariff. This includes revisions to the tariff that may credit the wholesale rate for electricity generated onto our system. Effective 05/01/2016: All net metered interconnections to the SELCO grid will be subject to a monthly Distribution Standby Charge of $2.50 per kW of installed solar capacity.  

Does SELCO offer any other solar incentives?

SELCO customers are now eligible to apply for the MLP Solar Rebate through MMWEC (see information above). This program offers a rebate of $1.20 per watt up to 50% of the installed cost (maximum rebate of $12,000, up to 10kW AC of installed capacity). Funding is available on a first-come first-serve basis. Applications will be accepted through December 30, 2020.

SELCO customers may be eligible for a Mass Solar Loan through the state’s Commonwealth Solar/Clean Energy Center program.  SELCO customers are also able to take advantage of any state or federal solar tax credits that might be available.

When you call HELPS for an energy audit, you can request a solar site evaluation as well. SELCO provides this service for free.

Can SELCO recommend any solar installers?

No.  SELCO does not recommend installers.  Be sure whomever you hire is a licensed contractor/electrician and that they pull all required building and electrical permits from the Town of Shrewsbury.


Do I have to own the solar panels?

Yes. Residential SELCO customers wishing to install solar must:

1. Own the home where the panels will be installed.

2. Own the panels. 

3. Own all power produced.


You cannot enter into panel leasing arrangements or third-party power purchase agreements within the SELCO service territory. This means that you may not lease solar panels from any company that will retain ownership of the panels or the power generated.
