Methodology: How We Ranked the Best Solar Companies in Watertown

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


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 Watertown

For many homeowners, whether or not you should invest in solar energy comes down to the cost. The overall price and potential savings vary depending on a few important factors such as:

  • Your energy bills: This will determine how much you can save. In Watertown, the average resident can save about $1,600 a year on their electricity bills.
  • Your income and budget: This shapes what type of solar panels you can purchase.
  • How much power your household consumes: Homes that use plenty of power each month may call for more solar panels and, consequently, be more costly, but will also enjoy more savings over time.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $20,000 over the first 20 years with your solar system, too.

Because of the cost of solar panels being lower than before as well as several solar incentives, they are a cost-effective investment for many homeowners.

Solar Incentives in Watertown

Although installing solar panels is typically a $15,000 to $25,000 investment, it can save you a lot of money in the long term due to smaller utility bills and government incentives. You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also potentially pair the ITC with other state and city rebates and benefits. Our article on solar incentives has more information on the incentives you can take advantage of in Watertown.

Environmental Impact of Switching to Solar in Watertown

Swapping traditional energy for solar is a compelling way to do your part for a more eco-friendly future. A question many homeowners might be thinking about is how much can they really help save the environment by going solar anyway? Using renewable energy for electricity rather than using nonrenewable energy is an effective way to reduce carbon dioxide emissions if you're worried about Watertown's sizable level of greenhouse gas emissions. Even though making solar panels emits carbon dioxide, the panels make up for it by considerably lowering the amount of CO2 you would have released if you still used traditional energy. In Watertown, you can reduce your carbon footprint by 80 pounds a year with solar panels. If you want to do what you can for the environment, you'll likely find that there are many benefits of adopting solar power other than just saving money on electricity. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's Watertown, WI Solar Company Rankings FAQs

Which solar power company is the best near me?

The top local solar company in Watertown is Sun Prairie Utilities, with a rating of 3.00 stars.

Are solar panels actually environmentally friendly?

Producing solar panels requires chemicals and produces toxic waste that can be bad for the environment, which is the main drawback of solar panels.

Is it worth putting solar panels on my home?

Solar panels can be a good investment for lots of homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already pretty low, solar panels might not be for you.

How often do solar panels need to be replaced?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of. What this means is the amount of energy they produce will have decreased by about 0.8% each year since installing them. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
