Methodology: How We Ranked the Best Solar Companies in Adelphi

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


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 Adelphi

Solar panels run off a free energy source — the sun — but to take advantage of this you must first pay to install your system. There are quite a few factors you should take into consideration when determining costs and your potential savings, such as:

  • How much sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won't be able to generate as much energy, which will leave you with lower savings on electric bills than someone with a roof that gets a lot of sunlight.
  • Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your power bills, which can generate an average of $16,000 of savings over 20 years.
  • The type of solar panels you have the money for: This hinges on how much you're willing to spend upfront.
  • Your current energy bills: Solar panels can noticeably decrease, or totally get rid of, your utility bills. In Adelphi, you can save an average of $76 a month.

Although a solar panel system costs a decent chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on a number of factors, including the kind of solar panels you get and your local electricity rates.

Solar Incentives in Adelphi

Although a solar power system is typically a $15,000 to $25,000 investment, it can save you a substantial amount of money in the long term because of smaller energy bills and government incentives. These incentives normally include cash rebates, tax breaks and/or performance-based incentives. They can lower how much you pay for going solar by 30%, upwards of 50% in some cases. Our article on solar incentives has more in-depth information on the incentives you can benefit from in Adelphi.

Environmental Impact of Switching to Solar in Adelphi

Making the switch to solar power is a good way to do what you can for a more sustainable future. But how much can installing solar panels actually help the environment? The average person has a substantial carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions every year, and electricity for their home, it can be overwhelming to think about what to do. Installing solar panels is a simple thing you can do to help. In Adelphi, the average household can reduce their carbon footprint by 60 pounds a year after going solar. If you want to do your part for the environment, you'll likely recognize that there are many benefits of adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is priceless.
