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
When picking a solar company, most homeowners or business owners wonder about the costs above all.Some main factors that affect the cost of installing solar panels on your home and how much it could save you over time include:
- System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
- How much power your home consumes: Households that consume plenty of electricity each month may require more solar panels and, consequently, more upfront cost, but will also enjoy more savings over time.
- Incentives: One thing that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save a decent amount of money on your power bills, which can give you an average of $16,000 of savings over 20 years.
- Your current power bills: Solar panels can greatly decrease, or completely eliminate, your utility bills. In National Harbor, you can save an average of $1,706 a month.
Solar is a valuable investment for most homeowners. You can generate your own energy instead of paying for it from the grid and take advantage of solar incentives, all while helping preserve the planet.

EcoWatch's National Harbor, MD Solar Company Rankings FAQs
What is the best solar panel company in National Harbor?
The best local solar company in National Harbor is Greenway home improvements, with a rating of 5.00 stars.
What are the best and worst things about solar power?
A few of the biggest pros are that it reduces your power bills, it’s a sustainable source of energy, and it can give you a good return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, the installation cost is pricey and solar panels aren’t always aesthetically pleasing.
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 power bill, the quicker your solar panel system will recoup your installation costs.
What are the different kinds 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, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
