Methodology: How We Ranked the Best Solar Companies in Nashua
EcoWatch's solar experts analyzed each solar company in Nashua 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 Nashua
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 Nashua
For many people, the decision of which solar company to hire depends on total costs.There are quite a few factors you should take into consideration when trying to figure out the overall cost and how much you can save, such as:
- Your income and budget: This guides what model of solar panels you can buy.
- Typical energy usage: The more electricity your household consumes on average and the larger your current power bills are, the more benefits you’ll see from making the switch to solar.
- Average daily sunlight: Since Nashua doesn’t get a lot of average daily sunlight, your solar system may not be able to generate enough energy to power your whole home, which influences how much your electricity bills will be.
- Incentives: Something that can reduce the cost of 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 on your utility bills, which can lead to an average of $19,000 of savings over 20 years.
Although a solar panel system costs a good chunk of money upfront, it can save you much more over time. The question of how much, though, depends on several factors, including the size of your house and your local electricity rates.

EcoWatch's Nashua, NH Solar Company Rankings FAQs
What is the top solar company in Nashua?
The highest-rated local solar company in Nashua is Sunrun Fusion New England, with a rating of 3.00 stars.
Are solar panels actually environmentally friendly?
Solar panels can be harmful 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 needs 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 14.6 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will recoup your installation costs.
What is solar panel capacity and how much do I need for my house?
Solar panel capacity is rated depending on how much power they generate under standard testing conditions. Since each panel can generally produce about 250 to 400 watts per hour, the average house will need 20 to 35 panels.
