Methodology: How We Ranked the Best Solar Companies in Swansea

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


Below are some the criteria we examined specifically for Illinois 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 Swansea

For many people considering switching to solar, the decision of which solar installer to choose comes down to pricing.The cost of solar and the savings it generates vary depending on a few key factors such as:

  • System size and type: Some models are more expensive than others, so the one you want can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Average daily sunlight: Since Swansea gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which impacts how much your electricity bills will be.
  • Your household's power bills: With high monthly power bills in Swansea, you could save about $850 a year with solar.
  • Incentives: Something that can reduce the cost of 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 on your power bills, which can generate an average of $15,000 of savings over 20 years.

There are many good benefits of solar despite the initial cost of installation. It can help the Earth and your bank account. In addition, it can increase the value of your home, leading to even more benefits if you want to sell your home later.

Environmental Impact of Switching to Solar in Swansea

An important reason so many are thinking of adopting solar energy is to help reduce their environmental impact.A question many homeowners might be asking themselves is how much can they really help preserve the environment by switching to solar power anyway? For people who want to help preserve the planet, going solar is a straightforward choice, especially since Swansea produces a very high amount of carbon dioxide emissions from its energy generation.Even though solar panel production releases carbon dioxide emissions, the panels make up for it by greatly lowering the amount of CO2 you would have produced if you still used nonrenewable energy.

That's why so many homeowners have been happy with using solar energy.
