Methodology: How We Ranked the Best Solar Companies in Wilmington

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


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 Wilmington

  • Your energy consumption: If your home uses a lot of energy, you'll benefit more from going solar.
  • Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 0 of the project cost. Your state and city may also have incentives and rebates that you can use. In addition, you can save about $13,000 over 20 years on your utility bills, not including incentives.
  • System size and type: Some models are more costly than others, so the one you get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.

Environmental Impact of Switching to Solar in Wilmington

There are many reasons to trade traditional energy for solar power, like saving money on utility bills and helping to reduce your carbon footprint.You may be trying to figure out – how much do solar panels do for the planet anyway? As stated by the EPA, electricity production is the second greatest source of greenhouse gas emissions and about 62% of our electricity comes from burning fossil fuels. Installing solar panels and switching to renewable energy can help bring down that statistic in a city like Wilmington that accounts for a sizable amount of carbon dioxide emissions each year.Since solar panels don’t release greenhouse gas emissions into the atmosphere when producing electricity, they’re a good swap for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 90 pounds each year. Since energy from the sun is plentiful and produces electricity without a carbon footprint, adding solar panels to your home is one easy step you can take to help protect the planet.
