Methodology: How We Ranked the Best Solar Companies in Sparta

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


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 Sparta

Although solar panels can save you money on utility bills over time, it's important to know the startup costs. Some important things that affect the cost and possible savings include:

  • Incentives: Tax-paying citizens who buy and install a solar energy system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $19,000 on your electricity bills over 20 years not including incentives.
  • How much energy costs for you: The average family in Sparta spends around $1,500 a year on electricity alone, so you could end up with that much in savings.
  • How much energy your household consumes: Households that use a lot of power each month may need more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.
  • The type of solar panel system you can afford: This depends on how much you're willing to spend upfront.

So is a solar panel system worth it? Whether you want to decrease your electric bills, carbon emissions or both, solar panels are a worthwhile investment for many Sparta homeowners.

They can cut the cost you pay for going solar by 30%, upwards of 50% depending on your location.

Environmental Impact of Switching to Solar in Sparta

Going solar can have a beneficial effect on the environment. But how much can installing solar panels actually help the environment? For those who are environmentally-conscious, switching to solar power is an easy choice, especially since Sparta produces a very high amount of carbon dioxide emissions from its energy generation. Once you go solar, your carbon footprint can be lowered by about 90 pounds each year. As you can see, investing in solar has so many other perks apart from saving money. One of the major ones is that you can help save the Earth too.
