Solar panels in Dedham cost $3.05-3.40 per watt installed in 2026. A typical 11.5 kW system costs $35,075-$39,100 before MA state incentives. The federal Section 25D residential tax credit expired December 31, 2025 -- homeowners receive $0 in federal credit. Massachusetts state incentives (SMART 3.0, net metering, state tax credit, and tax exemptions) still make solar highly profitable in Dedham.
SMART 3.0 (Solar Massachusetts Renewable Target) pays solar system owners $0.03/kWh for all electricity produced, locked in for 20 years. An 11.5 kW system in Dedham generates approximately $414/year in SMART income, totaling roughly $7,850 over the program duration. Low-income households qualify for $0.06/kWh (double rate). Battery storage adds $0.04/kWh on top.
Yes. Dedham has a 7-8.5 year payback period thanks to high Eversource electricity rates ($0.2836/kWh), SMART 3.0 income, and MA state incentives. The 20-year property tax exemption saves approximately $446/year given Dedham's tax rate. Over 25 years, a typical system saves around $128,000.
Dedham does not have a separate municipal solar incentive, but residents benefit from all statewide Massachusetts programs: SMART 3.0 ($0.03/kWh for 20 years), Eversource net metering (1:1 retail credit), ConnectedSolutions (battery demand response), the $1,000 MA state tax credit, sales tax exemption (6.25%), and the 20-year property tax exemption. These state incentives are among the strongest in the country.
ConnectedSolutions is Eversource's demand response program for battery owners. During peak grid events (primarily summer), you discharge your battery to the grid and earn $275/kW in summer and $50/kW in winter. A typical 10 kW home battery can earn $2,750 in summer plus $500 in winter, totaling $3,250/year. Dedham is in Eversource territory, which offers the highest ConnectedSolutions rates in MA.
