Methodology: How We Ranked the Best Solar Companies in Westmont

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


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 Westmont

For many people considering switching to solar, the decision of which solar company to go with depends on costs. The overall price and potential savings vary depending on some important factors such as:

  • Electricity consumption: The average household in Westmont uses a decent amount of, and so may save on their energy bills.
  • Your city: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
  • The type and model of solar panels you want to get: Higher-efficiency panels are more expensive, so that will determine your budget for your solar project.
  • Incentives: One thing that can make your solar project cost less 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 utility bills, which can lead to an average of $13,000 of savings over 20 years.

Though a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on several factors, including the kind of solar panels you get and your energy consumption.

Environmental Impact of Switching to Solar in Westmont

If you're thinking of adding solar panels to your home, one of the primary reasons why may be to lower your carbon dioxide emissions. But you may be wondering — how much exactly can you help the planet by using solar power? Something that can severely shape your carbon footprint is how long your commute is and how much you drive altogether. If you install solar panels and have an electric car, you can significantly cut back on your carbon dioxide emissions by charging your car at home. Although solar panel production emits carbon dioxide, the panels make up for it by significantly lowering the amount of CO2 you would have released if you still used traditional energy. In Westmont, you can reduce your carbon footprint by 90 pounds a year with solar panels. If you want to do what you can for the environment, you'll likely get that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is invaluable.

What are a few of the biggest advantages and disadvantages of switching to solar?

The greatest advantages of solar power are that it can lower or, in some cases, 100% eradicate your electricity bills, improve your home's value and reduce your carbon footprint. The greatest disadvantages are that solar panels can be costly to install, you may not save a lot if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Is it worth putting solar panels on my home?

Solar panels require a significant upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a range of factors like local electricity rates and how much direct sunlight your roof gets.

What is the best type of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. 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.
