Methodology: How We Ranked the Best Solar Companies in New Castle

EcoWatch's solar experts analyzed each solar company in New Castle 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 New Castle


Below are some the criteria we examined specifically for Delaware 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 New Castle

Although solar panels can help save you money on utility bills over time, it's important to know the startup costs. Some important factors that determine how much it will cost to install a solar panel system on your home and how much money you could save over time include:

  • The type and model of solar panels you're planning on getting: Higher-efficiency panels are more highly priced, so that will affect your budget for your solar project.
  • Your city: This affects how much sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 30% of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $16,000 over 20 years on your energy bills.
  • Your household's power bills: Based on the fairly high monthly energy bills in New Castle, you could save about $1,100 a year with solar.

Solar is a fruitful investment for most homeowners. You can produce your own energy instead of paying for it from the grid and make use of solar incentives and rebates, all while helping protect the Earth.

In our article on solar incentives, you can find out about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in New Castle

Installing solar panels can have a meaningful effect on the environment. But how much can switching to solar actually affect the environment?

If you want to do what you can for the environment, you'll most likely recognize that there are many good things about adopting solar energy other than just saving money on bills. You can also help protect the environment, which some would argue is worth more.
