Methodology: How We Ranked the Best Solar Companies in Lake Geneva

EcoWatch's solar experts analyzed each solar company in Lake Geneva 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 Lake Geneva


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 Lake Geneva

The cost of putting up a solar panel system has decreased greatly over the past few years, but it's still a significant investment for most homeowners. There are a few factors you should consider when determining how much it will cost and how much you can save, including:

  • Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your power bills, which can result in an average of $20,000 of savings over 20 years.
  • How much you spend on energy: If your local electricity rates are especially high, there's a good chance you'll get a higher return on your investment in a solar system. In Lake Geneva, you can save an average of $129 a month on your electricity bills.
  • Your income and budget: This affects what model of solar panels you can get.
  • Your energy consumption: If your household needs to use a lot of energy, you'll see more savings from installing solar panels.

There are lots of good benefits of solar even with the upfront cost of installation. It can help the Earth and your wallet. Plus, it can boost the value of your home, giving you even more benefits if you decide to sell your home later.

EcoWatch's Lake Geneva, WI Solar Company Rankings FAQs

Which solar installation company is the best in Lake Geneva?

The highest-rated local solar company in Lake Geneva is ilumen Solar, with a rating of 4.01 stars.

Are solar panels actually bad for the environment?

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

How long does it take for solar to pay for itself?

Solar panels generally pay for themselves in about 8.5 years, but your solar payback period will vary based on your utility costs. The higher your typical energy bill, the faster your solar panel system will recoup your installation costs.

How often do solar panels have to be replaced?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can decide to replace them once you've had them for that long or you can keep using 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.
