Methodology: How We Ranked the Best Solar Companies in Warren

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


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 Warren

The cost of installing a solar panel system has decreased immensely over the past few years, but it’s still a substantial investment for most homeowners.Some important things that influence the upfront cost and potential savings over time include:

  • System size and type: Some models are more pricy than others, so the one you want can raise or lower your initial investment. Plus, the more solar panels you need to get, the more it'll cost.
  • Average daily sunlight: Since Warren gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.
  • The cost of energy for you: If your local electricity rates are high, there's a good chance you'll end up with a higher return on your investment in a solar panel system. In Warren, you can save an average of $1,156 a month on your electricity bills.
  • Energy consumption: Installing a solar system may be too steep of an investment for homes that don’t need too much energy each month.

Because of the cost of solar panels being lower than before as well as local and federal solar incentives, they are a sound investment for the majority of homeowners.

Environmental Impact of Switching to Solar in Warren

If you’re planning on adding solar panels to your home, one of the primary reasons why may be to lower your carbon footprint.But how much can installing solar panels actually affect the environment? One thing to consider is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions.Though solar panel production releases carbon dioxide emissions, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used traditional energy. In Warren, you can reduce your carbon footprint by 90 pounds a year with solar panels. If you want to do what you can for the environment, you’ll likely recognize that there are many good things about adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is priceless.
