The Best Residential Solar Installers in Houston, Texas

In recent years, solar energy has become the most widespread and reliable renewable energy source. Sun power—to put it simply—is booming. And solar energy’s popularity has birthed an entire industry of contracting that handles the planning, installations, maintenance, and even permit-processing.

This list showcases the best residential contractors in Houston. In order to come up with this list, our editorial team gathered dozens of solar contractors in the area and assessed each with a set of criteria that measures the contractors’ overall work quality. The criteria included categories for awards, additional accolades, work history, the quality of previous projects, and the capacity of these firms’ in-house teams to deliver the best results when it came to solar facilities. Not surprisingly, the firms on this list continue to receive kind words from their previous clients. 

Adaptive Solar

4101 Greenbriar Dr. Suite #205B, Houston, TX 77098

Hundreds of Houston households and enterprises have come to Adaptive Solar for its solar services. Since its inception in 2010, company principals Richard Sherwood and Nick Paloski have steered Adaptive Solar into being more of a retail company than a construction firm. As a result, the firm is in a position to provide a hands-on approach to installation that previous customers continue to praise. 

On average, Adaptive Solar installations cost at $16,000. But the expenses are well worth the price considering that the firm takes care of the entire process. The firm is not a stranger to expansive solar installations like the one pictured below. Adaptive Solar properly and inconspicuously installed solar panels on this massive home, demonstrating their attention to detail and fluency in the solar industry. 

Freedom Solar Power

2000 Edwards St., Suite #B100 Houston, TX 77007

Since 2007, Freedom Solar Power has been providing full-service solar technology to the homes and businesses of Houston. With over 4,000 homes in its portfolio, Freedom Solar operates as one of Houston’s busiest residential solar providers. 

The firm is the only SunPower master dealer in all of Texas and one of the very few master dealers in the country. Master dealers are the highest, most exclusive level of accreditation SunPower awards to its dealers. That prestigious distinction is matched by industry awards, including the Association for Corporate Growth (ACG) Central Texas Growth Awards winner in 2016. 

Freedom Solar’s capacity to blend solar installation in with unconventional residential layouts really stands out. This Lakemoore Drive estate, for example, is a non-linear home with slanted roofing. Freedom successfully installed 350W panels that contribute 91% of household energy use, and it installed those panels with style and grace. Another one of their commercial solar projects, Strictly Pediatrics Surgery Center, was also a finalist or Solar Builder Magazine's 2016 Projects of the Year.

KnS Solar

3550 Lang Rd., Houston, TX 77077

KnS Solar is the brainchild of Guy Koloko—an immigrant from Africa, an alumnus of Kennesaw State University, and someone who has life-long expertise in the solar field. Armed with that extensive experience, Koloko takes charge of the day-to-day company operations in the U.S., Africa, and Colombia and oversees additional projects in Ghana, Togo, Cameroon, Nicaragua, and Iraq. Aside from managing a business, Koloko also does solar projects for charity. His international solar project, “Light in the Darkness”, aims to install solar system kits to remote orphanages and clinics in Africa, with Cameroon as the first beneficiary in 2020. Koloko is also set to open a solar store in Africa to distribute solar products. 

Despite the immensity of the firm’s business scale, the customers previously served by KnS point out how hands-on and attentive the KnS team is. The team packs two decades of combined industry experience spent providing the highest-rated solar panel equipment and energy solutions in a wide range of project sizes, from three kilowatts to three Megawatts. KnS was also involved in up to 120MW worth of combined solar farms.
