Frequently Asked Questions
How do I choose the best solar installer in Maine?▼
Get at least 3 quotes from different Maine solar installers. Verify licensing and insurance, check reviews on Google and BBB, ask about NABCEP certification, and compare warranty offerings. Look for installers with at least 5 years of experience and knowledge of Maine's specific permits and incentives.
How much does solar cost in Maine?▼
The average cost of solar in Maine is $2.88 per watt before incentives. For a typical 8kW system, that's approximately $23,040 before the 30% federal tax credit. Get multiple quotes to ensure you're getting a fair price.
What solar incentives are available in Maine?▼
All Maine homeowners can claim the 30% federal solar Investment Tax Credit (ITC). Solar installations are exempt from property tax increases.
How long does solar installation take in Maine?▼
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 Maine.
Should I get a solar lease or buy in Maine?▼
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 Maine, with a 8-year average payback period, buying usually makes financial sense if you can afford the upfront investment.
