Methodology: How We Ranked the Best Solar Companies in Round Rock

EcoWatch's solar experts analyzed each solar company in Round Rock 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 Round Rock


Below are some the criteria we examined specifically for Texas 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 Round Rock

Even though solar panels can help save you a good amount of money on electricity bills over time, it’s necessary to consider the startup costs.There are quite a few factors you should take into consideration when trying to figure out the overall cost and how much you can save, including:

  • The kind of solar panels you can afford: This is dependent on what your budget is.
  • Typical energy usage: The more energy your home uses on average and the greater your current electricity bills are, the more money you could save by going solar.
  • Your home's power bills: Based on the very high monthly electricity bills in Round Rock, you could save about $1,400 a year with solar.
  • Incentives: Something that can make your solar project cost less 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 on your energy bills, which can give you an average of $18,000 of savings over 20 years.

So is a solar system worth it? Whether you hope to lower your electric bills, carbon emissions or both, solar panels are a good investment for many Round Rock homeowners.

Environmental Impact of Switching to Solar in Round Rock

Lots of people want to do what they can to help save the planet, which in many cases is the primary reason they’re interested in installing solar panels.A question many might be thinking about is how much can they really help preserve the environment by switching to solar power anyway? A key thing to consider is your overall carbon footprint. For example, if you spend a lot of time driving to work, your footprint may be larger, so adopting solar power for your home can help offset that.Although making solar panels emits carbon dioxide, the panels make up for it by significantly decreasing the amount of CO2 you would have been responsible for if you still used nonrenewable energy. In Round Rock, you can reduce your carbon footprint by 80 pounds a year with solar panels. For people who care about the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
