Methodology: How We Ranked the Best Solar Companies in Castle Hills

EcoWatch's solar experts analyzed each solar company in Castle Hills 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 Castle Hills


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.

  • Whether or not your roof gets a lot of direct sunlight: This, and your roof configuration, affects affect how much energy your solar panels can produce.

Solar Incentives in Castle Hills

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 power more financially viable and accessible.You can qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also potentially use the ITC with other state and city incentives. You can find out about the incentives you can use in our article on solar incentives

Environmental Impact of Switching to Solar in Castle Hills

One of the best reasons to tap into solar energy is to cut your dependence on traditional energy sources like burning fossil fuels, which are harmful for the environment.You may be curious – how much does going solar do for the environment anyway? The EPA reports that electricity production is the second greatest source of greenhouse gas emissions and about 62% of our electricity is generated by burning fossil fuels. Using solar power can help bring down that number in a city like Castle Hills that is responsible for a sizable amount of carbon dioxide emissions each year.Since solar panels don’t release carbon dioxide emissions into the atmosphere when generating electricity, they’re a good trade for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 80 pounds each year. As you can see, trading traditional energy for solar has so many other perks besides saving money. One of the primary ones is that you can help save the planet too.

What is the best solar panel installer in Castle Hills?

The highest-rated local solar company in Castle Hills is Smartworld Energy, with a rating of 5.00 stars.

What are the pros and cons of solar power?

The biggest advantages of solar power are that it can lower or, in some cases, entirely cut your electricity bills, raise the value of your home and cut back on your carbon footprint. The disadvantages are that solar panels can be costly to install, you may not save as much if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

Is it worth putting solar panels on my roof?

Solar panels call for a considerable upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a variety of factors like local electricity rates and how much direct sunlight your roof gets.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much energy generation you want.
