Photovoltaic Technology Integration with Tensile Membrane Structures-a Critical Review

Abstract

Tensile membrane structures and photovoltaic technology have been developing completely independently one from the other until recently. After the realization that PV-membrane integration would benefit both of these systems, research on their common application began. Photovoltaic panels increase the energy efficiency of tensile membrane structures, while at the same time tensile membrane structures provide large areas for harvesting solar power. This symbiosis has been tested and proven both scientifically and in practice. This paper presents the state of the art of scientific research concerning tensile membrane structures fitted with photovoltaic technology. Based on this knowledge, possibilities and problems connected with photovoltaic technology integration in tensile membrane structures were identified. It was observed that they refer to three main types of properties affected by the integration, i.e.: thermal, energy, and structural properties. The main factors influencing these properties are PV-membrane integration methods and PV-membrane geometry. Furthermore, the conducted analysis allowed for identification of insufficiently explored areas in this field and recommendations for further research. The aim of this paper is to help in systematizing the existing knowledge which should have a positive effect to achieving widespread application of photovoltaic integrated membrane structures.
