Methodology: How We Ranked the Best Solar Companies in Largo

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


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 Largo

Although solar panels can help save you a good amount of money on energy over time, it's necessary to know the startup costs. There are quite a few factors you should consider when trying to determine the overall cost and how much you can save, including:

  • Average daily sunlight: Since Largo gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which impacts how much you can save on your energy bills.
  • Choice of solar panels: The kind of solar panels you get will affect your total cost. High-efficiency monocrystalline panels will cost more 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 opt for a higher number of more affordable panels.
  • How much you spend on energy: If your local electricity rates are high, there's a better chance you'll have a higher return on your investment in solar panels. In Largo, you can save an average of $73 a month on your electricity bills.
  • Incentives: The federal solar investment tax credit currently lets you lower your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can benefit from. Plus, you can save about $15,000 over 20 years on your utility bills, without incentives.

Solar is a valuable investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and take advantage of solar tax credits and rebates, all while helping protect the environment.

Solar Incentives in Largo

In an effort to increase the number of homes and businesses that use solar power, federal, state and local governments — and even some utility companies — offer incentives to help make solar more economical and accessible. There are a lot of federal, state and local rebates and tax credits that let you earn anywhere from 30% to 50% of your money in return after paying for solar panels. Check out our article on solar incentives to see what incentives you can take advantage of.

Environmental Impact of Switching to Solar in Largo

One of the best reasons to switch to solar energy is to decrease your dependence on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment. But how much can switching to solar actually help the environment? One thing you should consider is your overall carbon footprint. For example, if you spend a lot of time on the road and have an electric vehicle, you can install solar panels on your home to power your EV and therefore help offset your carbon emissions. Since solar panels don't release CO2 emissions into the atmosphere when producing electricity, they're a good substitute for nonrenewable energy sources. In fact, you could lower your carbon dioxide emissions by about 60 pounds each year. Since solar energy is abundant and generates electricity without free from carbon dioxide emissions, installing solar panels is one easy step you can take to help preserve the planet.
