Big Sun Solar

Big Sun Solar helps companies, nonprofits, and municipalities across Texas reduce energy costs and achieve sustainability goals through commercial solar. We design and deliver tailored systems with a hands-on, customer-first approach, focusing on performance and long-term value. While we operate exclusively in Texas, our work spans complex, high-impact projects that rival much larger firms. In addition to project delivery, we collaborate with utilities and local organizations to expand solar adoption through innovative programs. Headquartered in San Antonio, Big Sun Solar brings disciplined execution and local expertise to every project.
