Methodology: How We Ranked the Best Solar Companies in Great Falls

EcoWatch's solar experts analyzed each solar company in Great Falls 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 Great Falls


Below are some the criteria we examined specifically for Virginia 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 Great Falls

Although solar panels can save you a good amount of money on utility bills over time, it’s important to take into consideration the upfront costs.There are several factors you should consider when trying to figure out the overall cost and how much you can save, including:

  • 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 on your energy bills, which can result in an average of $17,000 of savings over 20 years.
  • average energy usage: The more power your household uses on average and the steeper your current electricity bills are, the more likely you'll benefit from making the switch to solar.
  • The model of solar panels you can buy: This is dependent on how much you’re willing to spend upfront.
  • How much sunlight your roof gets: If your roof doesn’t see much direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on energy bills than someone with a roof that gets plenty of sunlight.

There are many wonderful benefits of solar even with the initial cost of installation. It can help the environment and your bank account. Additionally, it can raise the value of your home, leading to even more benefits if you want to sell your home later.
