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

Solar panels are powered by a free energy source — the sun — but to take advantage of this you will first need to pay to set up your system.A few important factors that affect the cost of installing a solar panel system on your home and how much money you could save over time include:

  • How much power your home consumes: Homes that consume plenty of energy each month may need more solar panels and, as a result, be more costly, but will also enjoy more savings over time.
  • The type and model of solar panels you want: Some cost more, so that will influence your budget for your solar project.
  • Your city: This affects how much sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state may also have various incentives that you can take advantage of. Plus, you can save about $19,000 over 20 years on your utility bills, before factoring in incentives.

Due to solar panels now being cheaper than ever as well as several solar incentives, they are a sound investment for the majority of homeowners.

EcoWatch's Beloit, WI Solar Company Rankings FAQs

What is the most reputable solar panel installer in Beloit?

The best local solar company in Beloit is Agsun Corporation, with a rating of 3.00 stars.

What are the pros and cons of solar power?

A few of the biggest pros are that it lets you spend less on your power bills, it’s environmentally friendly, and it can give you a good return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, the startup costs are high and solar panels can look clunky on your roof.

Are solar panels worth it?

Solar panels can be a beneficial investment for lots of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already pretty low, solar panels might not be for you.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and how much energy generation you want.
