Hingham Municipal Lighting Plant Solar Rebate Program

HMLP customers who install residential solar systems up to 10 kW can receive a rebate check of $0.60 per watt of rated capacity, capped at $6,000 per account lifetime. For example, a 5 kW system would qualify for a $3,000 rebate, while a 10 kW system would receive the full $6,000 cap. You can get free solar quotes and incentive calculators through HMLP's partnership with EnergySage, and the federal 25D tax credit (covering 30% of costs) is also available until December 31, 2025.

Your customers can claim a per-watt rebate ($0.60/W) capped at $6,000 per residential account for systems up to 10 kW AC capacity. HMLP requires specific meter labeling on all installations: two red placards reading "HMLP SOLAR METER" and "HMLP BI-DIRECTIONAL METER" must be present on the main house meter and solar meter respectively. Rebates are issued as checks after system installation and are based on the system's rated AC output.

The rebate operates on a $0.60/W basis capped at $6,000 lifetime per account for residential PV systems up to 10 kW AC. HMLP administers rebates as check payments post-installation and uses EnergySage as a customer resource platform for quote generation and incentive transparency. The program targets Hingham residential customers and includes optional integration with HMLP's Connected Homes battery program for demand-response participation to reduce system load and costs.
