Methodology: How We Ranked the Best Solar Companies in Deerfield

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


Below are some the criteria we examined specifically for Illinois 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 Deerfield

For the majority of homeowners, the decision to invest in a solar energy system comes down to the cost.Some key factors that influence how much it will cost to install solar panels on your home and how much money you could save over time are:

  • System size and type: Some models are more costly than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
  • Your location: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: Something that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your power bills, which can result in an average of $14,000 of savings over 20 years.
  • How much energy your home consumes: Homes that need lots of power each month may require more solar panels and, consequently, be more costly, but will also enjoy more savings over time.

So is a solar panel system worth it? Whether you’re trying to decrease your electricity costs, carbon emissions or both, solar panels are a good investment for many Deerfield homeowners.
