Methodology: How We Ranked the Best Solar Companies in Merrimack

EcoWatch's solar experts analyzed each solar company in Merrimack 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 Merrimack


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 Merrimack

We get that for most homeowners, the choice to invest in solar hinges on installation costs.There are quite a few factors you should take into consideration when trying to figure out costs and your potential savings, such as:

  • Choice of solar panels: The kind of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money 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.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $19,000 over the first 20 years with your solar system, too.
  • How much energy costs for you: The typical family in Merrimack pays around $1,400 a year on energy use alone, so you could end up with that much in savings.
  • How much sunlight your roof gets: If your rooftop doesn’t get a lot of direct sunlight, your solar panel system won’t be able to make as much energy, which will leave you with lower savings on power bills than a house with a roof that gets a lot of sunlight.

There are several great benefits of solar despite the initial cost of installation. It can help the Earth and your wallet. Additionally, it can boost the value of your home, resulting in even more benefits if you decide to sell your home later.

EcoWatch's Merrimack, NH Solar Company Rankings FAQs

What is the best solar company in Merrimack?

The top local solar company in Merrimack is SunPower by BlueSel Home Solar, with a rating of 3.00 stars.

Are solar panels actually eco-friendly?

Solar panels can be bad 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. Solar panel manufacturing needs a lot of energy as well. The energy payback period is about 1 to 4 years.

Are solar panels worth it?

Solar panels can be a beneficial investment for most homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already pretty low, solar panels might not be for you.

When is the best time of year to install solar panels?

Although summer is the most common time people install solar panels, the optimal time is actually winter. You can save money since there's not as much demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
