Methodology: How We Ranked the Best Solar Companies in Prospect Heights

EcoWatch's solar experts analyzed each solar company in Prospect Heights 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 Prospect Heights


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 Prospect Heights

We get that for most homeowners, the choice to invest in solar rests on installation costs. Some key things that impact the upfront cost and potential savings over time include:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $13,000 over the first 20 years with your solar panels, too.
  • Your income and budget: This affects what kind of solar panels you can afford.
  • Where your home is: This influences how much sunlight your roof receives, which helps determine how many panels you need.
  • Energy consumption: Installing solar panels may be too pricey an option for homes that don't need a lot of energy a month.

Though a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars in the long term. The question of how much, though, depends on several factors, like the amount of daily direct sunlight available and incentives.

Solar Incentives in Prospect Heights

To increase the adoption of solar power, incentives are offered by the government — and even some utility companies — to help make solar more economical and accessible. State and city solar incentive programs depend on the location and, sometimes, utility company. A lot of states offer rebates for home solar power systems, in addition to the federal solar tax credit. For comprehensive information about local incentives, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Prospect Heights

If you're planning on adding solar panels to your home, one of the main reasons why may be to lower your greenhouse gas emissions. You may be curious — how much does going solar do for the environment anyway? If your family uses a lot of energy, you can impact the environment even more by switching to solar power. Even though solar panel production emits carbon dioxide, the panels make up for it by considerably reducing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Prospect Heights, you can reduce your carbon footprint by 90 pounds a year with solar panels. Since solar power is abundant and makes electricity without free from carbon dioxide emissions, installing solar panels is one easy step you can take to help preserve the environment.
