Methodology: How We Ranked the Best Solar Companies in Onalaska

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


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 Onalaska

When choosing a solar company, most homeowners or business owners wonder about the costs above all.There are quite a few factors you should consider when determining costs and your potential savings, including:

  • System size and type: Some models are more costly than others, so the one you get can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Incentives: One thing that can save you money on your solar project 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 $19,000 of savings over 20 years.
  • Average daily sunlight: Since Onalaska doesn’t get a lot of average daily sunlight, your solar system may not be able to generate enough energy to power your whole home, which impacts how much your solar panels can save you on your electricity bills.
  • How much power your household needs: If your home regularly uses a lot of energy, you'll see more savings from installing solar panels.

Solar is a worthwhile investment for most homeowners. You can generate your own power instead of paying for it from a utility company and take advantage of solar tax credits and rebates, all while helping the planet.
