Commercial Solar Rebate (>20 kW)

Photovoltaic

• All equipment must be UL-listed
• Equipment must come with a 20-year or greater manufacturer's warranty.
• Please Note: An automatic switch that disconnects from the grid in the event of a power failure. An AC safety disconnect switch must be installed at a location approved by the RMLD between the inverter and the electrical panel. The RMLD must have access to the disconnect switch at all times. The RMLD may temporarily disconnect the system to facilitate planned or emergency work.

Requirements

• RMLD pre-approval of the solar system one-line diagram is required.
• Installation must be done by a licensed electrician.
• An RMLD Utility Authorization Number (UAN) is required.
• A Town Wiring Inspection is required post-installation (A Town Electrical Permit is a prerequisite to the wiring inspection).
• RMLD inspection is required post-installation.
• A locus production meter is required, and the customer must sign up for a ten-year solar data plan.
• By participating in the program, the owner agrees to provide 100% of its Renewable Energy Certificates (RECs) to RMLD for the lifetime of the system.

Process Steps

• Contact RMLD's Integrated Resources Group at 781-942-6598 or email our office to discuss the scope of the project and for any questions you may have.
• Customers planning to install Renewable Energy with an output rating greater than 150 kWac are responsible for the cost of a system impact study done by an RMLD service provider.
• The RMLD highly recommends that customers have an Energy Assessment and make cost-effective energy efficiency upgrades such as lighting, appliances, and electronics prior to the installation of a solar system.
• A professional site assessment/shade study must be completed prior to submitting your application. Solar panels must be <30% shaded. If not mounted on a flat roof, the panel azimuth must be between 80 and 280 degrees.
• Choose a solar installer / contractor:
  • Installers must coordinate directly with the RMLD for all Customer-Owned Generation Applications, installation, locations, and interconnection agreements.
  • The installer must be able to provide information about operation and performance considerations relating to shading, snow cover, and maintenance of the system.
  • All systems must be fully owned (purchased/financed) by the customer of record; 3rd party ownership and/or energy resale is not permitted within the RMLD territory.
• Submit Request for Rebate Confirmation and Supporting Documentation by visiting the RMLD's Online Customer Rebate Portal.
• Customer is responsible for ensuring an accurate representation of the site. The customer must demonstrate that the system will not be subject to significant amounts of shade from buildings, trees, electricity poles, towers, chimneys, etc., by using a shading analysis tool and site photos. The RMLD reserves the right to reject any application if shading is greater than 30%. Be sure to receive a signed Approval to Install for the proposed project from the RMLD prior to starting the installation.
• The installer/contractor must obtain a Utility Authorization Number (UAN) by contacting the RMLD Customer Service at 781-942-6598 before submitting the application.
• The installation must be completed within 12 months of the project approval by the RMLD.
• Upon completion of system installation, obtain necessary approvals from local building and wire inspectors to operate the system and fulfill RMLD's Interconnection requirements.
• The RMLD will perform a routine follow-up inspection of the facility to see that all construction went as planned.
• Submit material and installation invoices to the RMLD.

Submit application and supporting documentation via RMLD's Online Customer Rebate Portal.

Required Supporting Documentation:

• RMLD Certificate of Completion (PDF)
• RMLD Customer-Owned Generation / Interconnection Application (PDF)
• RMLD Customer-Owned Generation Rate Acknowledgement Form (PDF)
• Shade Report
• One-Line Diagram
• Layout Sketch/Site Plan
• Manufacturer's Specification Sheets
• Engineering Analysis (if any available)
• Proof of Ownership (the customer must own the system)
• Solar Contract
• Loan Documents (if applicable)
• Proof of Payment
• Proof of Installation (example: a photo)

Application Deadline: Application and supporting documentation must be received within 180 days of final RMLD inspection.

Payment Method: Rebate will be issued as a check to the electrical account owner.

RMLD offers a solar buyback program for customers with on-site solar generation. When you generate more electricity than you use in a given hour, the excess is sent back to the grid and tracked by a bi-directional meter installed by RMLD. We only purchase this excess energy - specifically the fuel charge portion of the electricity rate - not the full retail rate.

The fuel charge is a variable rate that reflects the cost of power supply and is updated monthly. Customers can find the current rate here. Energy that is generated and used within the same hour does not qualify for buyback.
