Install & Connect Solar for MGED 

If installing a solar array, the array will be connected to your home’s electrical panel and our electric distribution system through our electric meter. You need MGED approval first.

MGED Approval 

To ensure the system will connect safely and reliably, our technical staff must review and approve the design and final installation. Once you have a solar contractor and decide on the system to be installed, you and your contractor must submit an Interconnection Application (PDF). If the system is installed before you received our approval, you run the risk of needing costly changes.

Once your system is operating, MGED’s meter will measure both the amount of electricity provided to you by MGED and the excess electricity sent back through the MGED meter. The MGED meter will record each amount and both will be reflected on your MGED bill.  MGED will not meter the total generation amount produced by your system, most of which will be used inside your home. Your solar installer should install a separate, generation meter for your solar array.  MGED does not install this generation meter. Learn More About the Solar Credit on Your Bill (PDF).

Below are the steps that must be followed prior to installing a solar array at your residence:

  1. Submit the following by email:
  2. Simplified Application/Interconnection Agreement (PDF) for Net Metered Electrical Generation
  3. This form must be printed and attached as a PDF.
  4. A one-line drawing of your generation system (Sample PDF)
  5. Specifications showing the materials (panels and inverters)
  6. Approval Confirmation – you will receive notice from MGED directly that your system and materials have been approved for installation. MGED will share this information with your contractor as well.
  7. If Approved- MGED will charge your account a $250 application fee, payable on your next bill.
  8. Apply for the MLP Solar Rebate- Your system design must meet specific program requirements for size limit, azimuth and shading to qualify for the rebate of $.60 per watt. In order to ensure that you are eligible for a rebate, MGED strongly recommends that you wait an additional 4 to 6 weeks for pre-approval of the rebate application from our rebate agency, Energy New England, before starting the installation. Apply online or call 888-772-4242 for more information.
  9. Electrical Permit- You (or your contractor/installer) must obtain an electrical permit from your town wiring inspector before you begin installation.
  10. Electrical Inspection/Town Wiring Inspector- After installation is complete, you or your contractor should call the town wiring inspector for a final inspection.
  11. System Inspection - Once your array is inspected by the Town, an MGED technician will need to complete a system inspection, prior to activation.  MGED will then complete a Certificate of Completion and will send you a copy along with a Permission to Operate letter.
  12. If Qualified for a MLP Solar Rebate- MGED will verify operation of your system with Energy New England who will arrange for payment of your rebate. Most rebates are issued within 8 weeks of receiving all required documentation. MGED will retain all future rights to Solar RECs as a condition of providing the rebate.
