What to watch for in a Massachusetts solar quote

Federal ITC must be exactly 30%

The 2025 residential clean energy credit (Form 5695) is 30% of eligible system cost with no cap for solar. If a quote shows a different percentage, ask why.

SMART incentives are not guaranteed

Massachusetts SMART program capacity fills up per utility. Your incentive rate depends on your utility, system size, and when you apply. Never treat SMART as guaranteed in a payback calculation.

Net billing ≠ net metering

Most MA utilities have moved from net metering (1:1 credit) to net billing (lower credit rate). Ask your installer what credit rate they assumed in the savings estimate.

Price-per-watt is your sanity check

Massachusetts solar typically runs $2.80–$4.50/W installed (2024 data). Above $5/W without a premium justification (slate roof, complex system) warrants a second quote.

Loan APR is not the full cost of financing

Many solar loans include a 10–25% dealer fee rolled into the principal. A '0.99% APR' loan on a $30,000 system can have $5,000+ in hidden fees. Ask for total repayment amount.

Production guarantees matter

A reputable installer will guarantee a minimum kWh output and have a remedy process if the system underperforms. Ask for it in writing before signing.
