Methodology: How We Ranked the Best Solar Companies in Beloit

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


Below are some the criteria we examined specifically for Wisconsin 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 Beloit

Even though solar panels can save you a decent chunk of change on electricity bills over time, it's important to consider the upfront costs. Some main factors that affect how much it will cost to install a solar panel system on your home and how much money you could save over time include:

  • Where your home is: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • System size and type: Some models are more costly than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • How much electricity your home consumes: Homes that need a lot of power each month may require more solar panels and, consequently, be more costly, but will also enjoy more savings over time.
  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 30% of the project cost. Your state and city may also have incentives and rebates that you can benefit from. In addition, you can save about $19,000 over 20 years on your utility bills, before factoring in incentives.

Even though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, like the angle of your roof and your current power bills.

Solar Incentives in Beloit

In an effort to increase the number of homes and businesses that use solar power, federal and local governments — and even some utility companies — offer incentives to help make switching to solar power more financially viable and accessible. There are several federal, state and local rebates and tax credits that can earn you some money in return after paying for a solar panel system. In our article on solar incentives, you can read about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Beloit

One of the most compelling reasons to adopt solar energy is to decrease your reliance on traditional energy sources like burning fossil fuels, which are destructive for the environment. You may be curious — how much do solar panels help the environment anyway? Switching to green energy for electricity instead of using nonrenewable energy is an effective way to lower carbon dioxide emissions if you're worried about Beloit's large level of greenhouse gas emissions. Once you go solar, your carbon emissions can be reduced by about 100 pounds each year. Since energy from the sun is plentiful and makes electricity without a carbon footprint, installing solar panels is one easy step you can take to help the planet.
