Going solar is one of the smartest investments New Hampshire homeowners and businesses can make. But choosing the right solar energy contractor is just as important as selecting the panels themselves. The contractor you choose will impact your system’s performance, long-term savings, and overall satisfaction.

If you’re thinking about making the switch to solar in New Hampshire, here’s how to choose the best solar energy contractor for your project.

What Does a Solar Energy Contractor Do?

A solar energy contractor is responsible for designing, permitting, installing, and maintaining your solar power system. From evaluating your roof to helping you navigate state and federal incentives, a qualified contractor is your guide through the entire solar journey.

Key Factors to Consider When Hiring a Solar Energy Contractor in NH

Finding the right contractor can feel overwhelming—but it doesn’t have to be. Use these essential criteria to evaluate your options.

1. Verify Licensing and Insurance

In New Hampshire, solar contractors must hold appropriate electrical licenses to perform installations safely and legally. Always ask:

  • Are you licensed in NH to install solar PV systems?
  • Do you carry general liability and workers’ compensation insurance?

Avoid companies that can’t produce documentation or are hesitant to answer questions about their qualifications.

2. Look for Local Experience

Choosing a solar energy contractor in New Hampshire means hiring someone familiar with the region’s permitting processes, utility interconnection policies, and weather conditions (especially snow load and winter performance).

*Bonus tip: Local contractors are also more likely to be responsive after the installation, especially if you ever need service or support.

3. Evaluate Customer Reviews and References

Read reviews on Google, EnergySage, SolarReviews, and the Better Business Bureau. Look for patterns—especially when it comes to customer service, installation quality, and responsiveness.

Reputable contractors will gladly connect you with recent customers who can speak about their experience.

4. Review Their Equipment and Warranties

Make sure your solar contractor offers reputable brands with solid performance warranties. High-efficiency panels, quality inverters, and durable racking systems can make a big difference in long-term performance. When talking to a solar company, look for:

  • Product warranty (usually 25 years)
  • Workmanship warranty (typically 5–10 years)
  • Production guarantees, if available

5. Analyze the Proposal Thoroughly

A professional solar proposal should include:

  • System size and estimated output
  • Cost breakdown (equipment, labor, permitting, etc.)
  • Expected savings and ROI
  • Available tax credits and incentives
  • Project timeline

*Pro Tip: Be cautious of quotes that seem too good to be true. Quality materials and experienced installers are worth the investment.

Questions to Ask a Solar Energy Contractor

Before you sign a contract, ask these important questions:

  • How many installations have you completed in New Hampshire?
  • Do you handle permitting and inspections?
  • Who will be performing the installation—your crew or subcontractors?
  • What kind of post-installation support do you provide?

Asking the right questions helps ensure you’re working with a contractor you can trust.

The Benefits of Choosing a Trusted Local Solar Energy Contractor

Hiring a New Hampshire-based solar energy contractor provides added peace of mind. You’ll get:

  • Local support before, during, and after installation
  • Personalized service from professionals who understand NH’s climate and utility landscape
  • Greater accountability and faster response times
