Methodology: How We Ranked the Best Solar Companies in Milton

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


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 Milton

For most homeowners, whether or not you should invest in solar energy comes down to the cost. Some key things that determine the cost and possible savings include:

  • Incentives: Tax-paying citizens who install a solar system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $20,000 on your energy bills over 20 years not including incentives.
  • How much energy costs for you: If your local electricity rates are especially high, there's a good chance you'll end up with a higher return on your investment in a solar panel system. In Milton, you can save an average of $124 a month on your electricity bills.
  • Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
  • Energy consumption: Installing a solar system may be too pricey an option for households that don't need a good amount of energy per month.

Solar is a worthwhile investment for most homeowners. You can make your own electricity instead of paying for it from the grid and take advantage of solar incentives and rebates, all while helping preserve the Earth.

Solar Incentives in Milton

If you're planning on making the switch to solar power, various government incentives and tax credits can immensely bring down your project costs and expedite the return on your investment. Regardless of what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 30% of how much your solar project cost when you file taxes, reducing the amount of taxes you owe that year. Plus, there may be some local incentives you can benefit from too. In our article on solar incentives, you can read about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Milton

A lot of people want to do their part to help protect the planet, which for many is the chief motivation to install solar panels. But — how much exactly can you help by using solar power? The more power your house uses, the the more the environment will benefit if you switch to solar as you won't need to use as much nonrenewable energy. In fact, if you install solar panels, you could lower your carbon dioxide emissions by about 100 pounds each year. For homeowners who care about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

What are some of the pros and cons of going solar?

The biggest advantages of solar power are that it can lower or, for some, 100% cut your electricity bills, improve the value of your home and lower your carbon footprint. The biggest disadvantages are that solar panels can be pricey to install, you may not see as many savings if you don't use a lot of electricity and it doesn't work for all roof types and locations.

Is it worth installing solar panels on my home?

Solar panels call for a significant upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a variety of factors like the cost of electricity near you and how much direct sunlight your roof gets.

When is the best time of year to install solar panels?

Although summer is the most common time people install solar panels, the best time is actually winter. You can save money since there's not as much demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.
