Methodology: How We Ranked the Best Solar Companies in De Pere

EcoWatch's solar experts analyzed each solar company in De Pere 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 De Pere


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 De Pere

When picking a solar company, most homeowners or business owners worry about the costs the most. There are a few factors you should consider when determining how much it will cost and how much you can save, such as:

  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 30% of the cost of your solar system installation from your taxes. Plus, not including incentives, you can save about $20,000 over 20 years on your energy bills.
  • Typical energy usage: The more power your household uses on average and the greater your current power bills are, the more likely you'll benefit from going solar.
  • The amount of sunlight your roof gets: This, and the configuration of your roof, affects affect how much energy your solar panels can generate.
  • System size and type: Some models are more expensive than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.

There are lots of great benefits of solar in spite of the initial cost of installation. It can help the environment and your finances. In addition, it can increase the value of your home, resulting in even more benefits if you decide to sell your home later.

One of the benefits of installing a solar panel system is earning incentives from the government. Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which allows you to claim 30% of your project costs when you file taxes, lowering the amount of taxes you owe that year. In addition, there may be some local incentives that stack with the ITC too. In our article on solar incentives, you can read about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in De Pere

One reason so many homeowners are thinking of adopting solar energy is to help reduce their environmental impact. A question many homeowners might have in mind is how much can they really help preserve the environment by switching to solar power anyway? In De Pere, where the energy generation can be rather dirty, going solar can have a significant impact on the environment since solar power is a renewable source of energy. While solar panel production emits carbon dioxide, the panels make up for it by significantly decreasing the amount of CO2 you would have released if you still used traditional energy. In De Pere, you can reduce your carbon footprint by 90 pounds a year with solar panels. The great things about solar power are abundant — just like solar power is! That's why so many people have been happy with making the switch to solar.
