Solar Panels

CMLP offers two rebate programs providing thousands of dollars towards the cost of installing solar panels at your home or business. You'll want to take advantage of both programs, if your system meets eligibility requirements. 

MLP Solar Program Rebate: Offers a one-time incentive of $1,200 per kW DC of solar photovoltaic (PV) capacity installed, capped at 50% of system cost or $30,000, whichever is less. CMLP and the Massachusetts Department of Energy Resources (DOER) provide matching contributions of $600 per kW DC of installed solar capacity to fund this incentive. Residential and commercial arrays of 25 kW DC or less installed by customers in good standing are eligible.

CMLP Solar PV Rebate:  Offers an additional one-time rebate of $625 per kW DC of installed solar PV generation capacity, capped at $3,125 per service address. Residential installations up to 167 kW AC and commercial installations of any size are eligible. 

Steps to Installing Solar

Here are the steps involved in applying for both rebates and installing solar at your home or business. If you are applying for the CMLP Solar PV Rebate only, the document submission requirements are listed in Step 4.6.

  1. Learn about the MLP Solar Program, which is administered for CMLP by Energy New England (ENE). Click here for an overview of the program and steps for getting started.
  2. We recommend that you identify at least three solar installers from whom to solicit proposals for your new solar PV system. You’ll find information to help you with this step at ENE's MLP Solar Program website and at CMLP’s Lease/Buy/Choose an Installer webpage. People who’ve already installed solar are also a good source of information about installer performance. Check online reviews, talk with people you know, or ask CMLP’s Energy Specialist Pamela Cady (pcady@concordma.gov; 978-318-3149) to put you in touch with Concord homeowners or businesses who’ve installed solar.
  3. When soliciting proposals from solar installers, tell them you are interested in applying for an MLP Solar Program Rebate and the CMLP Solar PV Rebate. Confirm that they’re familiar with the PV system and production meter design, installation and equipment criteria for the MLP Solar Program and the CMLP Solar PV Rebate and interconnection requirements outlined in the documents listed under Step 4.6
  4. Once you’ve signed a contract with a solar installer, work with them to complete the following documents needed to apply for an MLP Solar Program rebate
    1. MLP Solar Program Rebate Application (found here)
    2. Participant's Agreement (found here)
    3. Proof of property ownership (deed, recent tax bill)
    4. Copy of Installer/Homeowner or Business Owner Contract
    5. Shading analysis (DOER-approved shading tools can be found here in Contractor Packet or Program Manual)
    6. CMLP Solar PV Rebate  and interconnection documents required by CMLP:
      1. Residential or Commercial Interconnection Application
      2. CMLP Solar PV Rebate Application
      3. CMLP Solar PV Rebate Terms and Conditions
      4. Residential or Commercial Net Metering Policy Acknowledgement
      5. Wiring Diagram
      6. Specification Sheets for All Equipment (i.e. Solar PV Panels, Inverters and Energy Storage Systems, if applicable)
  5. All solar paperwork is bundled and sent via email to CMLP.
  6. CMLP staff reviews paperwork and forwards to ENE with approval if all requirements are met.(Note: Current CMLP electrical distribution system limitations may preclude the installation of residential or commercial systems over 25 kW without an accompanying energy storage system. Decisions are made on a case by case basis after engineering review.)
  7. ENE reviews paperwork, submits completed packages to DOER and notifies the customer, installer and CMLP that the Rebate Request has been submitted to DOER.
  8. DOER issues an Award Notification and notifies ENE.
  9. ENE notifies the customer and CMLP that the project can be completed (Installer must file for separate permits with the Building Department).
  10. Solar PV panels installed on property.
  11. Town Electrical Inspector visits site to give approval.
  12. CMLP Electrician installs "send and receive" meter (a brief power outage is required; new meter installed next to solar meter; property owner does not need to be on site).
  13. CMLP Engineer signs Approval to Operate (on-site visit not usually needed).
  14. ENE emails property owner & installer official Approval to Operate.
  15. Property owner begins generating their own power!
  16. Property owner receives one-time check by mail from Town of Concord for CMLP Solar PV Rebate (if rebate check requested rather than on-bill credit). This takes 4 – 6 weeks from Approval to Operate. (Note:If customer applied for both the CMLP Solar PV Rebate and the MLP Solar Program Rebate, separate checks for each rebate will arrive at different times.)  
  17. Contractor sends MLP Solar Program Validation Request documents to CMLP.
    1. Certificate of Completion
    2. Project Completion Form (provided by DOER upon reservation of award)
    3. Approved interconnection agreement, with approval to operate
    4. Evidence meter is installed and communicating
    5. Locus Meter Connection Form
    6. Change Request Form (if applicable)
    7. Invoice
  18. CMLP, ENE and DOER review the Validation Request documents.
  19. DOER issues Notification of Award, which ENE forwards to customer and CMLP.
  20. ENE invoices DOER and CMLP for the MLP Solar Program Rebate funds. Once funds have been received, ENE mails MLP Solar Program rebate check to customer.
  21. ENE connects Locus meter and provides CMLP, installer and customer with access.
