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
The cost of putting up a solar panel system has gone down immensely in the past few years, but it's still a large investment for most homeowners. There are quite a few factors you should take into consideration when trying to determine costs and your potential savings, including:
- Your income and budget: This affects what kind of solar panels you can get.
- Energy consumption: Installing solar panels may be a high-cost investment for households that don't use a lot of energy a month.
- 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 money on your energy bills, which can give you an average of $19,000 of savings over 20 years.
- How much energy costs for you: The average family in Nashua pays around $1,000 a year on home energy use alone, so you could gain that much in savings.
There are many wonderful benefits of solar despite the upfront cost of installation. It can help the environment and your wallet. In addition, it can raise the value of your home, resulting in even more benefits if you choose to sell your home later.

EcoWatch's Nashua, NH Solar Company Rankings FAQs
What is the best solar panel company in Nashua?
The best local solar company in Nashua is ReVision Energy, with a rating of 4.12 stars.
What are the pros and cons of solar power?
The biggest advantages of solar power are that it can decrease or, in some cases, 100% erase your electricity bills, improve the value of your home and cut back on your carbon footprint. The biggest 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 it doesn't work for all roof types and locations.
How long does it take to see a return on your investment after buying solar panels?
The average payback period for solar panel installation is about 10.1 years, but the exact period is influenced by the cost of electricity where you are, incentives and net metering programs.
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 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, like 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 efficiency you're looking for.
