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

Solar panels run off a free energy source — the sun — but to take advantage of this you will first need to pay to install your panels.Some significant things that determine the cost and possible savings include:

  • The amount of sunlight your area gets: Thanks to Wilmington’s high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.
  • Energy consumption: Installing a solar system may be an expensive option for homes that don’t use a lot of energy a month.
  • Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 0 of the project cost. Your state may also have incentives and rebates that you can benefit from. In addition, you can save about $13,000 over 20 years on your utility bills, without incentives.
  • Your income and budget: This determines what type of solar panels you can get.

Even though a solar panel system costs a sizable chunk of money upfront, it can save you much more over the lifespan of your panels. The question of how much, though, depends on several factors, like the angle of your roof and incentives.

Environmental Impact of Switching to Solar in Wilmington

If you’re thinking of adding solar panels to your home, one of the principal reasons why may be to lower your carbon dioxide emissions.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Wilmington, though. According to the EPA, electricity generation is the second greatest source of greenhouse gas emissions and about 62% of our electricity is generated by burning fossil fuels. Switching to a clean energy source like solar power can help lower that number in a city like Wilmington that accounts for a sizable amount of carbon dioxide emissions each year.Because solar panels don’t release CO2 emissions into the atmosphere when producing 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. The great things about solar power are plentiful — just like solar power is! That's why so many people have been happy with making the switch to solar.

What is the best solar company in Wilmington?

The top local solar company in Wilmington is SunPower by Sun N Us, with a rating of 3.00 stars.

What are some of the major advantages and disadvantages of adopting solar power?

A few of the biggest pros are that it lets you spend less on your electricity bills, it’s eco-friendly, and it gives you a decent return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, they cost a lot upfront and solar panels can be an eyesore.

Are solar panels worth it?

Solar panels can be a good investment for most homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already reasonably low, solar panels might not be for you.

What is solar panel capacity and how much do I need for my house?

Solar panel capacity is how much energy the panels can generate under ideal conditions (a sunny day around noon). The average household has to get between 20 and 35 panels to cover how much energy they need.
