Methodology: How We Ranked the Best Solar Companies in South Hadley

EcoWatch's solar experts analyzed each solar company in South Hadley 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 South Hadley


Below are some the criteria we examined specifically for Massachusetts 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 South Hadley

When choosing a solar company, most homeowners or business owners wonder about the costs the most.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:

  • How much energy your home consumes: Households that consume lots of energy each month may require more solar panels and, consequently, be more expensive, but will also enjoy more savings over time.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state and even local utility companies may also have various incentives that you can benefit from. Plus, you can save about $19,000 over 20 years on your utility bills, without incentives.
  • The amount of sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panels won’t be able to produce as much energy, which will give you lower savings on electric bills than a roof that gets a lot of sunlight.
  • Your energy bills: This will impact your savings. In South Hadley, the average homeowner can save about $1,700 a year on their electricity bills.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you much more over time. The question of how much, though, depends on a number of factors, such as the kind of solar panels you get and incentives.

Solar Incentives in South Hadley

To increase solar panel installation and usage, federal, state and local governments – and even some utility companies – offer incentives to help make going solar more financially viable and accessible.You are eligible for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also potentially stack the ITC with other state and city incentives. For detailed information about incentives that apply to you, see our article on solar incentives.

Environmental Impact of Switching to Solar in South Hadley

One of the best reasons to tap into solar power is to reduce your dependence on nonrenewable energy sources like burning fossil fuels, which are damaging for the environment.Something many people might have in mind is how much can they really help preserve the environment by switching to solar power anyway? How much energy you use is a key factor to think about. The more electricity your home uses, the bigger your impact when you switch to solar energy.Once you go solar, your carbon dioxide emissions can be cut by about 40 pounds every year. As you can see, using solar power has so many other rewards outside of saving money. One of the most important ones is that you can help save the planet too.

EcoWatch's South Hadley, MA Solar Company Rankings FAQs

What is the most reputable solar installer in South Hadley?

The best local solar company in South Hadley is Northeast Solar, with a rating of 5.00 stars.

Are solar panels really environmentally friendly?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth putting solar panels on my roof?

Solar panels call for a significant upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a variety of factors like local electricity rates and how much direct sunlight your roof gets.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
