Methodology: How We Ranked the Best Solar Companies in Keene
EcoWatch's solar experts analyzed each solar company in Keene 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 Keene
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 Keene
The cost of putting up solar panels has dropped greatly in the past several years, but it's still a substantial investment for most homeowners. The installation cost is just one important factor you should take into account when looking into installing solar panels. How much it'll cost and how much you can save depend on things including:
- How much you spend on energy: If your local utility rates are quite high, there's a better chance you'll get a higher return on your investment in a solar panel system. In Keene, you can save an average of $83 a month on your electricity bills.
- How much electricity your household consumes: Homes that need lots of power each month may call for more solar panels and, as a result, be more costly, but will also save more on their energy bills over time.
- The model of solar panels you want: More efficient models are more costly, so that will shape your budget for your solar project.
- Incentives: Those who purchase and install a solar system this year can save 30% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $19,000 on your energy bills over 20 years excluding incentives.
There are lots of good benefits of solar despite the upfront cost of installation. It can help the environment and your bank account. In addition, it can raise the value of your home, leading to even more benefits if you want to sell your home later.

Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of how much you paid for your solar installation on your tax return, reducing the amount of taxes you owe that year. Additionally, there may be some local incentives you can benefit from too. For more information about incentives for homeowners in Keene, see our article on solar incentives.
Environmental Impact of Switching to Solar in Keene
There are tons of reasons to trade traditional energy for solar power, like saving money on utility bills and helping to lower your carbon footprint. But you may be curious — how much exactly can you help by using solar power? An important thing to think about is your overall carbon footprint. For example, if you have a long commute, your footprint may be bigger, so adopting solar power for your home can help offset that. In Keene, the average household can lower their carbon footprint by 40 pounds a year once they go solar. Since solar power is abundant and generates electricity without free from carbon dioxide emissions, adding solar panels to your home is one easy step you can take to help preserve the environment.

EcoWatch's Keene, NH Solar Company Rankings FAQs
Which solar installation company is the best near me?
The top local solar company in Keene is Valley Solar, with a rating of 4.06 stars.
Are solar panels really bad for the environment?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 10.2 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the quicker your solar panel system will pay for itself.
When is the best time of year to install solar panels?
Despite summer being the most popular time people install solar panels, the ideal time is actually winter. You can save money since there's decreased demand during the winter months, and it lets you be up and running with solar for the higher power bills you may get during the summer.
