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

Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you will first need to pay to set up your panels. The installation cost is just one important factor you should keep in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • The make and model of solar panels you want: Some are more highly priced, so that will affect your budget for your solar project.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 30% of the cost of installing your solar panel system from your taxes. Additionally, not including incentives, you can save about $14,000 over 20 years on your energy bills.
  • Your current electric bills: Solar panels can dramatically lower, or totally eradicate, your utility bills. In Warren, you can save an average of $75 a month.
  • Your city: This influences how much sunlight your roof receives, which helps determine how many panels you need.

Although a solar panel system costs a good chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on a number of factors, such as the kind of solar panels you get and incentives.

EcoWatch's Warren, IL Solar Company Rankings FAQs

Which solar power company is the best in Warren?

In Warren, ilumen Solar is the top local solar company. Our team of experts rates it 4.01 stars, so it's a great choice if you're planning on installing solar panels on your home.

What are the pros and cons of solar power?

A few of the biggest pros are that it decreases your electricity bills, it's a sustainable source of energy, and it gives you a decent return on your investment (ROI). The most notable cons are that solar panels don't produce electricity at night, they cost a lot upfront and solar panels can look clunky on your roof.

Are solar panels worth it?

Solar panels can be a great investment for most homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already fairly low, solar panels might not be for you.

What are the different types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also cost more. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much efficiency you're looking for.
