Methodology: How We Ranked the Best Solar Companies in Littleton
EcoWatch's solar experts analyzed each solar company in Littleton 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 Littleton
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 Littleton
We know that for most homeowners, the choice to invest in solar hinges on installation costs. There are a few factors you should consider when trying to figure out the overall cost and how much you can save, including:
- Incentives: Tax-paying citizens who buy and install a solar energy system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $20,000 on your utility bills over 20 years excluding incentives.
- How much energy costs for you: The typical household in Littleton shells out around $1,100 a year on energy use alone, so you could end up with that much in savings.
- Your energy consumption: If your household uses a lot of energy, you'll benefit more from installing solar panels.
- Choice of solar panels: The type of solar panels you want will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
Thanks to solar panels now being cheaper than ever as well as several solar incentives, they are a solid investment for many homeowners.

Environmental Impact of Switching to Solar in Littleton
If you're thinking of adding solar panels to your home, one of the primary reasons why may be to reduce your reliance on nonrenewable energy. You may be curious — how much does making the switch help the planet anyway? In Littleton, where the energy generation could be cleaner, going solar can have a big impact on the environment since solar power is a renewable source of energy. While making solar panels releases carbon dioxide emissions, the panels make up for it by significantly decreasing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Littleton, you can reduce your carbon footprint by 40 pounds a year with solar panels. The advantages of solar power are abundant — just like solar power is! That's why so many people have been happy with using solar energy.

EcoWatch's Littleton, NH Solar Company Rankings FAQs
Which solar installation company is the best in Littleton?
The best local solar company in Littleton is SunCommon, with a rating of 4.05 stars.
Are solar panels actually eco-friendly?
Manufacturing solar panels requires chemicals and produces toxic waste that can be harmful for the environment, which is the main downside of solar panels.
How long does it take for solar to pay for itself?
Solar panels typically pay for themselves in about 9.8 years, but your solar payback period will vary depending on your utility costs. The more your typical electricity bill, the faster your solar panel system will pay for itself.
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 expensive. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much efficiency you're looking for.
