Methodology: How We Ranked the Best Solar Companies in Frankfort

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


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 Frankfort

For the majority of homeowners, whether or not you should invest in a solar energy system comes down to the cost. There are quite a few factors you should take into consideration when trying to figure out costs and your potential savings, including:

  • Energy consumption: Solar may be too pricey an option for households that don't need too much energy a month.
  • Your energy bills: This will dictate how much you can save. In Frankfort, the average resident can save about $900 a year on their electricity bills.
  • The kind of solar panels you want: Higher-efficiency panels cost more, so that will determine your budget for your solar project.
  • Incentives: Those who purchase and install a solar system this year can save 30% of their total solar spend by taking advantage of the federal solar investment tax credit. You can also save about $13,000 on your electricity bills over 20 years without incentives.

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

Solar Incentives in Frankfort

There are several federal, state and local rebates and tax credits that can earn you a decent amount of money in return after buying a solar panel system. You can learn about the incentives you can take advantage of in our article on solar incentives

Environmental Impact of Switching to Solar in Frankfort

There are a few important reasons why homeowners are interested in solar energy: to help their wallet and the environment. But you may be curious — how much exactly can you help the planet by going solar? The amount of energy you use is an important factor to keep in mind. The more electricity your home uses, the larger your impact when you go solar. Although making solar panels releases carbon dioxide emissions, the panels make up for it by greatly reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Frankfort, you can reduce your carbon footprint by 90 pounds a year with solar panels. The benefits of solar power are abundant — just like solar power is! That's why so many Frankfort residents have been happy with using solar energy.
