Methodology: How We Ranked the Best Solar Companies in Green Oaks

EcoWatch's solar experts analyzed each solar company in Green Oaks 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 Green Oaks


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 Green Oaks

We know that for most homeowners, the choice to invest in solar highly depends on installation costs. There are several factors you should consider when trying to figure out the overall cost and how much you can save, such as:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 30% of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $14,000 over the first 20 years with your system, too.
  • Your income and budget: This shapes what model of solar panels you can buy.
  • How much electricity your household consumes: Homes that consume plenty of electricity each month may call for more solar panels and, as a result, be more expensive, but will also save more on their energy bills over time.
  • The amount of sunlight your city gets: Thanks to Green Oaks' high amount of average daily sunlight, you should be able to save a decent amount on your electric bills.

Even though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on several factors, such as the amount of daily direct sunlight available and incentives.

Solar Incentives in Green Oaks

If you're thinking about making the switch to solar energy, a number of government incentives and subsidies can drastically bring down your project costs and expedite the return on your investment. Everyone can take advantage of the federal Solar Investment Tax Credit (ITC), which will allow you to claim 30% of how much you paid for your solar installation when you file taxes, reducing the amount of taxes you owe that year. Plus, there may be some state and city incentives that can save you some extra money too. In our article on solar incentives, you can find out about the incentives you qualify for in Green Oaks.

Environmental Impact of Switching to Solar in Green Oaks

Lots of people want to do their part for the planet, which for many is the main motivation to install a solar system. But how much can using solar energy instead of traditional energy actually affect the environment? The amount of energy you use is a key factor to keep in mind. The more electricity your household consumes, the greater your impact when you go solar. Even though solar panel manufacturing emits carbon dioxide, the panels make up for it by greatly decreasing the amount of CO2 you would have released if you still used traditional energy. In Green Oaks, you can reduce your carbon footprint by 90 pounds a year with solar panels. For people who want to help the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

What is the best solar panel installation company in Green Oaks?

In Green Oaks, SunRise Solar Attic Fans is the best local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your home.

Are solar panels really good for the environment?

Making solar panels needs to use chemicals and produces toxic waste that can be harmful for the environment, which is the main drawback of solar panels.

How long does it take for solar to pay for itself?

Solar panels usually pay for themselves in about 13.4 years, but your solar payback period will vary based on your utility costs. The more your typical electricity bill, the quicker your solar panel system will pay for itself.

What are the different kinds of solar panels?

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