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
For many people considering switching to solar, the decision of which solar company to go with comes down to total costs.The cost and possible savings vary depending on some important factors such as:
- How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won’t be able to generate as much energy, which will give you lower savings on electricity bills than a roof that gets a lot of sunlight.
- Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 0 of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $19,000 over 20 years on your energy bills.
- Your income and budget: This affects what type of solar panels you can buy.
- How much energy your home consumes: Households that use a lot of energy each month may need more solar panels and, therefore, be more costly, but will also save more on their energy bills over time.
There are several wonderful benefits of solar even with the initial cost of installation. It can help the Earth and your bank account. In addition, it can increase the value of your home, giving you even more benefits if you decide to sell your home later.

Solar Incentives in Exeter
There are many reasons why going solar is a great investment. One of them involves some government incentives you can take advantage of.Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 0 of how much you paid for your solar installation on your tax return, lowering the amount of taxes you owe that year. In addition, there may be some state and city incentives that can save you some extra money too. For detailed information about local incentives, see our article on solar incentives.

EcoWatch's Exeter, NH Solar Company Rankings FAQs
Which solar power company is the best in Exeter?
The top local solar company in Exeter is ReVision Energy, with a rating of 5.00 stars.
What are the advantages and disadvantages of solar power?
The greatest advantages of solar power are that it can decrease or, in some cases, 100% eradicate your electricity bills, improve your home’s value and bring down your carbon footprint. The disadvantages are that solar panels can be expensive to install, you may not save a lot if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.
How long does it take for solar to pay for itself?
The average payback period for solar panel installation is about 15.0 years, but the exact period varies by local electricity costs, incentives and net metering programs.
How long do solar panels last?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is the amount of energy they produce will have decreased significantly after that point. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
