Methodology: How We Ranked the Best Solar Companies in Cornelius

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


Below are some the criteria we examined specifically for North Carolina 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 Cornelius

Even though solar panels can save you money on power bills over time, it’s important to consider the upfront costs.Some significant things that affect the cost and possible savings include:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $17,000 over 20 years with your solar panels, too.
  • The amount of sunlight your roof gets: Because of Cornelius’s very high amount of average daily sunlight, you should be able to save a lot on your power bills.
  • Choice of solar panels: The type of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
  • How much power your home consumes: Households that consume plenty of electricity each month may require more solar panels and, therefore, be more costly, but will also save more on their energy bills over time.

So are solar panels worth it? Whether you want to lower your electric bills, carbon dioxide emissions or both, solar panels are a good investment for many Cornelius homeowners.

Solar Incentives in Cornelius

Switching to solar power has plenty of considerable benefits. Not only can it help preserve the planet, but you can also save a good amount of money on your installation with various government incentives.Local solar incentive programs vary by location and, sometimes, utility company. Many states offer rebates for solar panels, in addition to the federal solar tax credit. For more information about incentives that apply to you, see our article on solar incentives.

Environmental Impact of Switching to Solar in Cornelius

One reason so many are considering switching to solar power is to help reduce their environmental impact.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Cornelius, though. The amount of energy you use is an important factor to think about. The more energy your home uses, the larger your impact when you switch to solar energy.Because solar panels don’t release carbon dioxide emissions into the atmosphere when creating electricity, they’re a good swap for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 60 pounds each year. As you can see, using solar power has so many other rewards beyond saving money. One of the main ones is that you can help save the Earth too.
