Methodology: How We Ranked the Best Solar Companies in Peterborough
EcoWatch's solar experts analyzed each solar company in Peterborough 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 Peterborough
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 Peterborough
The cost of installing solar panels has dropped significantly over the past several years, but it's still a substantial investment for most homeowners. A few important factors that dictate how much it will cost to install a solar panel system on your home and how much money you could save over time are:
- The amount of sunlight your home gets: Because of Peterborough's relatively low amount of average daily sunlight, you might not see as many savings on your energy bills.
- How much energy costs for you: The typical household in Peterborough spends around $1,000 a year on energy use alone, so you could be looking at that much in savings.
- Incentives: Those who buy and install a solar system this year can save 30% of their overall solar costs by using the federal solar investment tax credit. You can also save about $19,000 on your electricity bills over 20 years without incentives.
- Your income and budget: This affects what type of solar panels you can afford.
Solar is a profitable investment for most homeowners. You can generate your own electricity instead of paying for it from a utility company and make use of solar tax credits and rebates, all while helping preserve the Earth.

Take a look at our article on solar incentives to learn what incentives you can benefit from.
Environmental Impact of Switching to Solar in Peterborough
There are a few big reasons why people are interested in solar energy: to help their wallet and the environment. But you may be wondering — how much exactly can you help the environment by going solar? In a city like Peterborough where commute times can be pretty long, going solar can help offset some of your carbon dioxide emissions from driving. Once you go solar, your carbon emissions can be cut by about 40 pounds a year. Since solar energy is plentiful and produces electricity without a carbon footprint, installing solar panels is one easy step you can take to help preserve the environment.

EcoWatch's Peterborough, NH Solar Company Rankings FAQs
What is the top solar installer in Peterborough?
In Peterborough, ReVision Energy is the most reputable local solar company. Our team of experts rates it 4.12 stars, so it's a solid choice if you're planning to add solar panels to your roof.
What are the pros and cons of solar power?
The main advantages of solar power are that it can lower or, in some cases, entirely eradicate your electricity bills, improve your home's value and reduce your carbon footprint. The main disadvantages are that solar panels can be costly to install, you may not save as much if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
Is it worth putting solar panels on my home?
Solar panels can be a fruitful investment for many homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already reasonably low, solar panels might not be for you.
What are the different types of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
Our goal is to reach as many people as we can with sensible solutions like solar energy.
