Methodology: How We Ranked the Best Solar Companies in Allenstown

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


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 Allenstown

We understand that for lots of homeowners, the decision to invest in solar highly depends on installation costs.The overall price and potential savings vary depending on some key factors such as:

  • The kind of solar panels you can purchase: This hinges on how much you’re willing to spend upfront.
  • How much you spend on energy: If your local power rates are quite high, there's a good chance you'll see a higher return on your investment in a solar panel system. In Allenstown, you can save an average of $1,407 a month on your electricity bills.
  • 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 utility bills, which can lead to an average of $19,000 of savings over 20 years.
  • Typical energy usage: The more electricity your household consumes on average and the greater your current energy bills are, the more benefits you’ll see from making the switch to solar.

Though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, like the amount of daily direct sunlight available and your current power bills.

Environmental Impact of Switching to Solar in Allenstown

An important reason so many homeowners are thinking of installing solar panels is to help reduce their environmental impact.But how much can installing solar panels actually affect the environment? One thing to keep in mind is your overall carbon footprint. For example, if you have a long commute time and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good trade for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 40 pounds each year. Since energy from the sun is renewable and produces electricity without CO2 emissions, adding solar panels to your home is one easy step you can take to help preserve the environment.

EcoWatch's Allenstown, NH Solar Company Rankings FAQs

What is the top solar panel company in Allenstown?

In Allenstown, SunPower by BlueSel Home Solar is the best local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're planning to add solar panels to your roof.

What is the negative environmental impact of solar panels?

Producing solar panels needs to use chemicals and produces toxic waste that can be dangerous for the environment, which is the main drawback of solar panels.

Is it worth installing solar panels on my roof?

Solar panels can be a great investment for lots of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already pretty low, solar panels might not be for you.

What are the different kinds of solar panels?

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 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 energy generation you want.
