Yes — Maine has moderate solar potential and commercial solar economics are strong in 2026. The federal ITC 48E provides a 30% tax credit, MACRS allows accelerated 5-year depreciation (plus 40% bonus depreciation), and the 179D deduction may stack if the system is part of a broader energy efficiency package. C-PACE financing is available in Maine, enabling 100% financing with cash-flow-positive projects from Day 1. Typical commercial solar payback in Maine ranges from 4–9 years depending on project size, financing, and utility rate class.
