The average cost of solar in New Hampshire is $3 per watt before incentives. For a typical 8kW system, that's approximately $24,000 before the 30% federal tax credit. Get multiple quotes to ensure you're getting a fair price.

All New Hampshire homeowners can claim the 30% federal solar Investment Tax Credit (ITC). Additional incentives include: Rebate $0.20/W up to $1,000. Solar installations are exempt from property tax increases.

The physical installation typically takes 1-3 days. However, the full process from contract signing to system activation usually takes 4-12 weeks, with most of that time spent on permitting and utility approval. Timelines vary by installer and local jurisdiction in New Hampshire.

Buying (with cash or a solar loan) typically provides the best long-term value since you own the system and receive all incentives. However, leases and PPAs require no upfront cost and still save on electricity. In New Hampshire, with a 7-year average payback period, buying usually makes financial sense if you can afford the upfront investment.
