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

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


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 Wisconsin

When deciding on a solar company, most homeowners or business owners care about the costs above all.The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • Your income and budget: This shapes what kind of solar panels you can get.
  • Energy consumption: Installing solar panels may be a high-cost investment for households that don’t need too much energy per month.
  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panels won’t be able to produce as much energy, which will give you lower savings on electric bills than a house with a roof that gets plenty of sunlight.
  • 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 incentives and rebates that you can use. In addition, you can save about $20,000 over 20 years on your utility bills, without incentives.

Solar is a rewarding investment for most homeowners. You can make your own energy instead of paying for it from the grid and benefit from solar tax credits and rebates, all while helping preserve the Earth.

Solar Incentives in Lake Wisconsin

Although installing solar panels is typically a large investment, it can save you a substantial amount of money in the long term because of reduced energy bills and government incentives.Local solar incentive programs depend on the location and, sometimes, utility company. A lot of states offer rebates for solar panels, in addition to the federal solar tax credit. For detailed information about incentives for homeowners in Lake Wisconsin, see our article on solar incentives.

Environmental Impact of Switching to Solar in Lake Wisconsin

One of the best reasons to switch to solar energy is to decrease your dependence on traditional energy sources like burning fossil fuels, which are harmful for the environment.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Lake Wisconsin, though. The average person has a substantial carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions every year, and powering their home, it can be overwhelming to figure out what to do. Going solar is a simple thing you can do to help.While solar panel production releases carbon dioxide emissions, the panels make up for it by greatly reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Lake Wisconsin, you can reduce your carbon footprint by 100 pounds a year with solar panels. If you want to do what you can for the environment, you’ll likely recognize that there are many benefits of adopting solar power other than just saving money on bills. You can also help preserve the environment, which some would argue is more valuable.
