Methodology: How We Ranked the Best Solar Companies in National Harbor

EcoWatch's solar experts analyzed each solar company in National Harbor 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 National Harbor


Below are some the criteria we examined specifically for Maryland 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 National Harbor

Solar panels run off a free energy source — the sun — but to take advantage of this you will need to pay to set up your system.A few main 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 are:

  • Choice of solar panels: The kind of solar panels you are interested in getting will affect your total cost. High-efficiency monocrystalline panels are more expensive 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 go with a higher number of more affordable panels.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 0 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.
  • How much you spend on energy: The typical household in National Harbor spends around $1,700 a year on home energy use alone, so you could be looking at that much in savings.
  • Average daily sunlight: Since National Harbor gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.

There are several good benefits of solar in spite of the upfront cost of installation. It can help the environment and your wallet. In addition, it can raise the value of your home, leading to even more benefits if you want to sell your home later.

EcoWatch's National Harbor, MD Solar Company Rankings FAQs

What is the top solar company in National Harbor?

The top local solar company in National Harbor is Advanced Solar, with a rating of 4.90 stars.

What are the best and worst things about solar power?

The biggest advantages of solar power are that it can decrease or, for some, entirely eradicate your electricity bills, improve your home’s value and reduce your carbon footprint. The biggest disadvantages are that solar panels can be pricey to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 14.8 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will recoup your installation costs.

What are the different types of solar panels?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
