Methodology: How We Ranked the Best Solar Companies in Oak Creek

EcoWatch's solar experts analyzed each solar company in Oak Creek 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 Oak Creek


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 Oak Creek

For many people, the decision of which solar company to go with depends on how much it’ll cost.The cost and possible savings vary depending on a few key factors such as:

  • Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 0 of the project cost. Your state and city may also have incentives and rebates that you can use. Additionally, you can save about $23,000 over 20 years on your utility bills, not including incentives.
  • Choice of solar panels: The type of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • How much electricity your household consumes: Households that use plenty of power each month may need more solar panels and, consequently, be more expensive, but will also enjoy more savings over time.
  • Whether or not your roof gets a lot of direct sunlight: This, plus your roof configuration, affects affect how much energy your solar panels can make.

As a result of solar panels now being cheaper than ever as well as several solar incentives, they are a solid investment for the majority of homeowners.
