Methodology: How We Ranked the Best Solar Companies in Exeter
EcoWatch's solar experts analyzed each solar company in Exeter based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Exeter
Below are some the criteria we examined specifically for New Hampshire solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Exeter
When deciding on a solar company, most homeowners or business owners wonder about the costs above all. Some key things that affect the upfront cost and potential savings over time include:
- Your home's power bills: Based on the high monthly energy bills in Exeter, you could save about $950 a year with solar.
- The type of solar panels you can afford: This depends on your income and budget.
- Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that's equal to a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can give you an average of $19,000 of savings over 20 years.
- Energy consumption: Installing a solar system may be a high-cost option for homes that don't use a good amount of energy each month.
Solar is a valuable investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and benefit from solar incentives, all while helping the planet.

Solar Incentives in Exeter
Adopting solar power has lots of considerable benefits. Not only can it help preserve the planet, but you can also save a good amount of money on your installation with various government incentives. Regardless of what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of how much your solar project cost on your tax return, reducing the amount of taxes you owe that year. In addition, there may be some local incentives you can benefit from too. In our article on solar incentives, you can find out about the incentives you qualify for near you.
Environmental Impact of Switching to Solar in Exeter
Installing solar panels can have a positive effect on the environment. Something many homeowners might have in mind is how much can they really help preserve the environment by switching to solar power anyway? The amount of energy you use is a significant factor to consider. The more power you use, the greater your impact when you go solar. Because solar panels don't release greenhouse gas emissions into the atmosphere when generating electricity, they're a good trade for traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 40 pounds each year. The advantages of solar power are plentiful — just like solar power is! That's why so many Exeter residents have been happy with making the switch to solar.
