Methodology: How We Ranked the Best Solar Companies in Koshkonong

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


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 Koshkonong

While solar panels can save you a good amount of money on electricity bills over time, it’s necessary to consider the upfront costs.Some key things that influence the upfront cost and potential savings over time include:

  • Your income and budget: This determines what kind of solar panels you can afford.
  • Energy consumption: Installing a solar system may be too steep of an option for households that don’t use a good amount of energy per month.
  • Where your home is: This influences how much sunlight your roof receives, which helps determine how many panels you need.
  • How much energy costs for you: The average household in Koshkonong spends around $1,300 a year on energy use alone, so you could be looking at that much in savings.

Solar is a fruitful investment for most homeowners. You can generate your own energy instead of paying for it from a utility company and make use of solar incentives and rebates, all while helping protect the planet.

What are the pros and cons of solar power?

A few of the biggest pros are that it decreases your electricity bills, it’s environmentally friendly, and it gives you a significant return on your investment (ROI).

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

Solar panels generally pay for themselves in about 13.3 years, but your solar payback period will depend on your utility costs. The higher your typical power bill, the quicker your solar panel system will recoup your installation costs.

How often do solar panels have to be replaced?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
