If you are an MGED customer considering a solar system for your home, we have important information that you need to know.
If you're just starting out
Here are some helpful resources to learn more about:
- How solar works at home
- Incentives and financing solar options
- The process to connect to MGED in our Solar Guide
Why we need to work with you and approve your installation
If you install a solar array, your system will be connected to your home's electrical panel AND our electric distribution system through the electric meter. To make sure that the systems will connect safely and reliabily, our technical staff needs to review & approve the design and final installation before the system can be connected and run through our meter. We install a bi-directional meter which measures both the electricity you buy from MGED and the excess electricity sent back through the department’s meter. This meter will record both amounts and you will be billed or credited for the value (based on delivery rates) of the “net” amount or difference between what was delivered by MGED and what was sent to MGED. We will not meter the total amount produced by your energy system, most of which will be used inside your home. Your solar installer should install a separate meter for your solar system.

Steps to connect a Solar Array for Net Metering
When you have found a solar contractor and decided on the system to be installed, take these steps to confirm that your system can be connected to the MGED distribution system. If your contractor installs your system before our approval of the application, you run the risk of needing costly changes before we can allow your solar array to operate while connected to our lines.
1. Submit the following by mail to:
Solar Applications Manager
Middleborough Gas & Electric Department

- Simplified Application/Interconnection Agreement for Net Metered Electrical Generation
- A one-line drawing of your generation system (sample) showing that it meets our system installation requirements
- Specifications showing the materials (panels & inverters) to be installed meeting all required codes as noted in the agreement
2. Approval confirmation – you will receive notice from MGED directly that your system layout and materials have been approved for installation. We will share this information with your contractor if you wish.
Apply for the MLP Solar Rebate. Your system design must meet specific program requirements for tilt angle, azimuth and shading to qualify for this rebate of $1.20 per watt. If applying for the MLP Solar Rebate, you'll need to wait an additional 4 - 6 weeks for approval of the rebate application from the rebate agency, Energy New England before starting the installation. Apply online or call 888-772-4242 for more information.
3. Electrical Permit - You (or your contractor/installer) must obtain an electrical permit from your town wiring inspector.
4. Electrical Inspection/town wiring inspector – After the system installation is complete, you or your contractor should call the town wiring inspector for a final inspection.
5. System Inspection/MGED Engineer - Our technician will schedule our inspection prior to turn-on. Our Engineer will review the system and approve for operation. MGED finalizes the Certificate of Completion - We will then send you a Permission to Operate letter for your records.
6. If you've qualified for a MLP Solar Rebate, we will verify operation of your system with the rebate agency, Energy New England who will arrange for payment of your rebate within 8 weeks of completion. MGED will retain all future rights to SRECs as a condition of providing the rebate.
