Methodology: How We Ranked the Best Solar Companies in Erin

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


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 Erin

Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you will need to pay to set up your system. A few important factors that affect the cost of installing solar panels on your home and how much it could save you over time are:

  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 30% of the cost of installing your solar panel system from your taxes. Additionally, not including incentives, you can save about $20,000 over 20 years on your energy bills.
  • Energy consumption: Installing solar panels may be an expensive option for households that don't need too much energy a month.
  • The cost of electricity in your area: If your local energy rates are especially high, there's a better chance you'll have a higher return on your investment in a solar panel system. In Erin, you can save an average of $127 a month on your electricity bills.
  • The kind of solar panel system you have the money for: This is dependent on how much you're willing to spend upfront.

Solar is a profitable investment for most homeowners. You can produce your own energy instead of paying for it from the grid and benefit from solar incentives, all while helping preserve the planet.

Solar Incentives in Erin

One of the good things about installing a solar panel system is receiving federal and potentially state incentives.

In our article on solar incentives, you can see the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Erin

Installing solar panels is a great way to do your part for a more eco-friendly future. You may be trying to figure out — how much does making the switch help the environment anyway? Regardless of your location, you can help save the environment by switching to solar energy, but homes that consume more energy will have an even bigger impact. When you go solar, your carbon footprint can be reduced by about 90 pounds a year. If you want to do your part for the environment, you'll likely get 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 worth more.

EcoWatch's Erin, WI Solar Company Rankings FAQs

What is the best solar installer in Erin?

In Erin, WindSoleil Solar and Wind Energy Services is the best local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're looking to install solar panels on your home.

Are solar panels actually bad for the environment?

Producing solar panels uses chemicals and produces toxic waste that can be bad for the environment, which is the main negative thing about solar panels.

Is it worth installing solar panels on my house?

Solar panels call for a large upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.

How long do solar panels last?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is their energy production will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
