We founded Big Sun Solar in 2015 to drive the mass adoption of solar by making it affordable, accessible and understandable to all. We’re fulfilling our mission by building a team that shares that same passion for building a renewable future and has deep experience in solar energy, technology and engineering. With roots in Texas, we’re proud to fulfill this passion right here in San Antonio. 

Trusted by leading brands such as Cavender, Baywood Hotels and Rush Enterprises, Big Sun Solar is #1 in customer service for Texas businesses. While every project is designed for maximum financial returns for our clients, it’s our Net Promoter Score of 88 that sets us apart as an industry leader. We have over 45 years of combined experience in solar energy, engineering rooftops, carports and ground mount systems coupled with experience from partnering directly with CPS Energy to build 5 megawatts (MW) of community-owned solar power.
