Methodology: How We Ranked the Best Solar Companies in Summit
EcoWatch's solar experts analyzed each solar company in Summit 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 Summit
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 Summit
Solar panels run off a free energy source — the sun — but to take advantage of this you must first pay to install your panels. The cost of solar and the savings it generates vary depending on a few important factors such as:
- The kind of solar panel system you can purchase: This hinges on what your budget is.
- Incentives: Something that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your power bills, which can generate an average of $13,000 of savings over 20 years.
- Average daily sunlight: Since Summit gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which influences how much you can save on your energy bills.
- How much power your home consumes: Households that need plenty of electricity each month may need more solar panels and, therefore, be more expensive, but will also save more on their energy bills over time.
There are many good benefits of solar even with the initial cost of installation. It can help the environment and your wallet. In addition, it can raise the value of your home, giving you even more benefits if you decide to sell your home later.

State and city solar incentives depend on the location and, sometimes, utility company. Many states offer rebates for solar panels, in addition to the federal solar tax credit. Our article on solar incentives goes over more detailed information on the incentives you can take advantage of in Summit.
Environmental Impact of Switching to Solar in Summit
There are a few main reasons why homeowners are interested in solar energy: to put more money in their bank account and to help the planet. But — how much exactly can you help the planet by going solar? The more power your household uses, the the more the environment will benefit if you switch to solar as you won't need to use as much nonrenewable energy. Because solar panels don't release greenhouse gas emissions into the atmosphere when generating electricity, they're a good swap for traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 90 pounds each year. As you can see, using solar power has so many other rewards beyond saving money. One of the primary ones is that you can help save the planet too.

EcoWatch's Summit, IL Solar Company Rankings FAQs
What is the most reputable solar company in Summit?
The best local solar company in Summit is ilumen Solar, with a rating of 4.01 stars.
Are solar panels actually good for the environment?
Solar panels can be bad for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to dispose of safely once they've reached the end of their lifespan. Making solar panels uses a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take for solar to pay for itself?
Solar panels generally pay for themselves in about 13.5 years, but your solar payback period will depend on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will pay for itself.
What is solar panel capacity and how much do I need for my house?
Solar panel capacity is rated based on the amount of power they produce under standard testing conditions. Since each panel can usually produce about 250 to 400 watts per hour, the average household will need 20 to 35 panels.
