Section 25D (the 30% residential solar tax credit) expired December 31, 2025 under the OBBBA. Milton homeowners buying cash or loan receive $0 in federal credit. However, third-party system owners (PPA/lease) can still claim the commercial Section 48/48E ITC -- which translates to lower PPA rates for you.

Solar panels in Milton cost $3.10-3.45 per watt installed in 2026. A typical 12 kW system costs $37,200-$41,400 before MA state incentives. The federal Section 25D residential tax credit expired December 31, 2025 -- homeowners receive $0 in federal credit. Massachusetts incentives (SMART 3.0, net metering, state tax credit, and tax exemptions) still make solar highly profitable in Milton.
Homes directly bordering the Blue Hills Reservation may have tree canopy shading from the reservation edge, particularly on the western and southern borders. However, most Milton homes have sufficient southern exposure for effective solar production. Modern shade analysis using satellite imagery and LIDAR can identify any issues before installation. Homes further from the reservation boundary (Milton Centre, East Milton) typically have excellent solar access.
SMART 3.0 (Solar Massachusetts Renewable Target) pays solar system owners $0.03/kWh for all electricity produced, locked in for 20 years. A 12 kW system in Milton generates approximately $432/year in SMART income, totaling roughly $8,200 over the program duration. Low-income households qualify for $0.06/kWh (double rate). Battery storage adds $0.04/kWh on top.
Yes. Milton has a fast payback period of 7-8.5 years thanks to high Eversource electricity rates ($0.2836/kWh), SMART 3.0 income, and MA state incentives. With Milton median home values around $850K and a $1.38 property tax rate, the 20-year property tax exemption saves approximately $543/year. Over 25 years, a typical system saves around $135,000.
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. Milton is in Eversource territory, which offers the highest ConnectedSolutions rates in MA.
