Methodology: How We Ranked the Best Solar Companies in Grayslake

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


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 Grayslake

We get that for many homeowners, the choice to invest in solar highly depends on installation costs.The installation cost is just one important factor you should consider when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • The type and model of solar panels you’re thinking of getting: More efficient models have higher prices, so that will determine your budget for your solar project.
  • Your household's power bills: With high monthly electricity bills in Grayslake, you could save about $1,200 a year with solar.
  • average energy usage: The more electricity your home uses on average and the greater your current power bills are, the more benefits you’ll see from going solar.
  • Average daily sunlight: Since Grayslake gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which impacts how much you can save on your energy bills.

Though a solar panel system costs a good chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on a number of factors, including the size of your solar panel system and your current power bills.

What are the best and worst things about solar power?

A few of the biggest pros are that it lets you spend less on your electricity bills, it’s a sustainable source of energy, and it provides a good return on your investment (ROI).

When should I install solar panels?

Despite summer being the most common time people install solar panels, the optimal 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 higher power bills you may get during the summer.
