Methodology: How We Ranked the Best Solar Companies in Henniker

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


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 Henniker

The cost of installing solar panels has gone down greatly in the past few years, but it’s still a large investment for most homeowners.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • System size and type: Some models are more expensive than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • How much power your household needs: If your household uses a lot of energy, you'll benefit more from installing solar panels.
  • Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your utility bills, which can lead to an average of $19,000 of savings over 20 years.
  • Your city: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.

Solar is a worthwhile investment for most homeowners. You can make your own energy instead of paying for it from a utility company and make use of solar incentives and rebates, all while helping the Earth.

Solar Incentives in Henniker

Although a solar power system is typically a large investment, it can save you a substantial amount of money over several years because of reduced energy bills and government incentives.Local solar incentive programs vary by location and, sometimes, utility company.

Environmental Impact of Switching to Solar in Henniker

One of the best reasons to switch to solar power is to decrease your dependence on traditional energy sources like burning fossil fuels, which are destructive for the environment.You may be wondering – how much does going solar help the planet anyway? An important thing to consider is your overall carbon footprint. For example, if you have a long commute, your footprint may be larger, so switching to solar energy for your house can help offset that.After you go solar, your carbon footprint can be reduced by about 40 pounds every year. As you can see, using solar power has so many other benefits beyond saving money. One of the major ones is that you can help save the environment too.

Which solar panel installer is the best near me?

In Henniker, SunPower by BlueSel Home Solar is the top local solar company. Our team of experts rates it 3.00 stars, so it's a great choice if you're planning on installing solar panels on your home.

What are a few of the pros and cons of switching to solar?

A few of the biggest pros are that it decreases your electricity bills, it’s a sustainable source of energy, and it can give you a significant return on your investment (ROI).

Solar panels can be a great investment for many homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already fairly low, solar panels might not be for you.

What is the efficiency of solar panels?
