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

The cost of putting up a solar panel system has gone down greatly over the past several years, but it's still a substantial investment for most homeowners. The cost of solar and the savings it generates vary depending on some key factors such as:

  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can use. Plus, you can save about $15,000 over 20 years on your utility bills, before factoring in incentives.
  • Where your home is: This influences how much sunlight your roof receives, which helps determine how many panels you need.
  • How much you spend on energy: The typical household in Swansea shells out around $940 a year on energy alone, so you could gain that much in savings.
  • How much energy you use: If your home regularly uses a lot of energy, you'll reap more rewards from going solar.

So is installing solar panels worth it? Whether you're trying to reduce your electric bills, carbon dioxide emissions or both, solar panels are a solid investment for many Swansea homeowners.

Solar Incentives in Swansea

If you're considering switching to solar energy, a variety of government incentives and solar rebates can dramatically lower the cost of the project and speed up the return on your investment. On top of the federal solar investment tax credit, there are also some local benefits, which in almost all cases, stack with the federal incentive, so you get to save even more. Check out our article on solar incentives to find out what incentives are available to you.

Environmental Impact of Switching to Solar in Swansea

One of the best reasons to embrace solar power is to reduce your reliance on nonrenewable energy sources like burning fossil fuels, which are destructive for the environment. Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Swansea, though. No matter where you are, you can help save the environment by switching to solar energy, but homes that consume lots of energy will have a bigger impact. While solar panel production emits carbon dioxide, the panels make up for it by considerably lowering the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Swansea, you can reduce your carbon footprint by 100 pounds a year with solar panels. For people who care about the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.

EcoWatch's Swansea, IL Solar Company Rankings FAQs

What is the top solar installer in Swansea?

The highest-rated local solar company in Swansea is PricingUtilities, with a rating of 3.00 stars.

What are a few of the major pros and cons of adopting solar power?

The greatest advantages of solar power are that it can reduce or, for some, 100% erase your electricity bills, improve the value of your home and lower your carbon footprint. The greatest disadvantages are that solar panels can be expensive to install, you may not save a lot if you don't use a lot of electricity and it doesn't work for all roof types and locations.

How long does it take to see a return on your investment after installing solar panels?

Solar panels generally pay for themselves in about 12.3 years, but your solar payback period will vary based on your utility costs. The more your typical power bill, the faster your solar panel system will recoup your installation costs.

When should I put up solar panels?

Although summer is the most common time people install solar panels, the perfect time is actually winter. You can save money since there's decreased 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.
