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

Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you first need to pay to set up your system. The overall price and potential savings vary depending on a few key factors such as:

  • Typical energy usage: The more electricity your home consumes on average and the higher your current electricity bills are, the more money you could save by switching to solar.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of your solar system installation from your taxes. In addition, not including incentives, you can save about $17,000 over 20 years on your energy bills.
  • The model of solar panel system you can afford: This hinges on what your budget is.
  • Your energy bills: This will affect how much money you might save. In Great Falls, the average resident can save about $1,400 a year on their electricity bills.

Thanks to the cost of solar panels being lower than before as well as local and federal solar incentives, they are a sound investment for most homeowners.

Solar Incentives in Great Falls

Although a solar power system is typically a $15,000 to $25,000 investment, it can save you a substantial amount of money over the lifespan of your solar panels because of lower energy bills and government incentives. There are several federal, state and local rebates and tax credits that may earn you a decent amount of money back after paying for a solar panel system. Check out our article on solar incentives to see what incentives you can benefit from.

Environmental Impact of Switching to Solar in Great Falls

An important reason so many are considering switching to solar power is to help lower their environmental impact. You may be curious — how much does making the switch do for the environment anyway? Everyone can help save the planet by switching to solar energy, but homes that consume lots of energy will have a greater impact. In fact, if you make the switch to solar power, you could be looking at reducing your carbon dioxide emissions by about 60 pounds each year. As you can see, trading traditional energy for solar has so many other perks apart from saving money. One of the main ones is that you can help save the Earth too.
