Efficient utilization of energy generation techniques is gaining more prominence in the design and engineering of built structures. One of the most established techniques used is through solar energy-harnessing via photovoltaic technology. In this research, integrating photovoltaics is further explored in the textile architecture domain to capitalize on the large areas typically recognized in tensile/doubly curved structures and textile facades; a design proposal is made for a textile-to-organic photovoltaic (OPV) integration, performed during the weaving process, to form a modular structural fabric with solar-energy-harnessing potential to be used in textile architecture applications. Laboratory testing is extensively used to determine both the fabrics' and the solar film’s strengths as well as verify the design procedure.
