Methodology: How We Ranked the Best Solar Companies in Hillsborough
EcoWatch's solar experts analyzed each solar company in Hillsborough 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 Hillsborough
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 Hillsborough
For the majority of homeowners, the decision to invest in solar energy boils down to the cost.There are quite a few factors you should consider when trying to figure out how much it will cost and how much you can save, including:
- The kind of solar panel system you can afford: This is dependent on how much you’re willing to invest upfront.
- Incentives: Something that can save you money on your solar project 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 utility bills, which can give you an average of $19,000 of savings over 20 years.
- Your current electricity bills: Solar panels can greatly lower, or totally get rid of, your utility bills. In Hillsborough, you can save an average of $1,407 a month.
- How much sunlight your roof gets: If your roof doesn’t get a lot of direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on power bills than a roof that gets plenty of sunlight.
So are solar panels worth it? Whether you hope to reduce your electric bills, carbon dioxide emissions or both, solar panels are a solid investment for many Hillsborough homeowners.

Environmental Impact of Switching to Solar in Hillsborough
If you’re thinking of adding solar panels to your home, one of the main reasons why may be to lower your carbon footprint.A question many homeowners might have in mind is how much can they really help save the environment by switching to solar power anyway? One thing that can severely shape your carbon footprint is how long your commute is and how much you drive altogether. If you install solar panels and drive an electric car, you can vastly decrease your carbon dioxide emissions by charging your car at home.In fact, if you adopt solar power, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. Since solar energy is abundant and generates electricity without a carbon footprint, installing solar panels is one easy step you can take to help preserve the environment.
EcoWatch's Hillsborough, NH Solar Company Rankings FAQs
Which solar panel installer is the best in Hillsborough?
In Hillsborough, Sunup Solar is the best local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your house.
Are solar panels actually environmentally friendly?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle safely once they’ve reached the end of their lifespan. Solar panel manufacturing requires 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?
The average payback period for solar panel installation is about 14.6 years, but the exact period varies depending on local electricity costs, incentives and net metering programs.
What is the best type of solar panel?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much energy generation you want.
