Methodology: How We Ranked the Best Solar Companies in Delaware
EcoWatch's solar experts analyzed each solar company in Delaware 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 Delaware
Below are some the criteria we examined specifically for Pennsylvania 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 Delaware
We get that for many homeowners, the decision to invest in solar hinges on installation costs.The cost of solar and the savings it generates vary depending on a few important factors such as:
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Excluding incentives, you can save an average of $15,000 over the first 20 years with your solar panels, too.
- The kind of solar panel system you can buy: This depends on how much you’re willing to invest upfront.
- The cost of energy for you: If your local power rates are quite high, there's a good chance you'll see a higher return on your investment in solar panels. In Delaware, you can save an average of $1,243 a month on your electricity bills.
- The amount of sunlight your roof gets: Due to Delaware’s relatively low amount of average daily sunlight, you might not see as many savings on your energy bills.
Although a solar panel system costs a good chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on a number of factors, such as the angle of your roof and your current power bills.

One of the best reasons to switch to solar energy is to minimize your reliance on nonrenewable energy sources like burning fossil fuels, which are hazardous for the environment.But you may be curious – how much exactly can you help the planet by going solar? Regardless of your location, you can help save the environment by switching to solar energy, but homes that use a lot of energy will have an even greater impact.Though solar panel production emits carbon dioxide, the panels make up for it by greatly decreasing the amount of CO2 you would have been responsible for if you still used traditional energy. In Delaware, you can reduce your carbon footprint by 50 pounds a year with solar panels. Since energy from the sun is plentiful and generates electricity without releasing carbon emissions, making the switch to solar power is one easy step you can take to help preserve the environment.
