The Solar Spline project tackles parameters of adaptability and photovoltaic energy production as well as light and shadow in the form of a three-dimensional lightweight structure. It also investigates the potential of such a conception for an extension of external shading structures into the urban realm.

The prototypical demonstrator that was built with an interdisciplinary team of architecture and design students in close collaboratin with Dr. Markus Schein of the School of Art and Design Kassel. It covers roughly an area of 30 m². This canopy is comprised of 300 organic photovoltaic cells (OPV), provided at no charge by OPVIUS GmbH, that are integrated into the lightweight structure. This ‘solar cloud’ seems to be suspended in midair, held in place by two white supporting ropes roughly 70 m in length (d = 20mm), forming a three-dimensional figure. The supporting ropes are anchored between a group of trees and the ground by an array of thin, almost invisible dark cables (d = 2mm).  The ‘solar cloud’ is composed of a series of rope carriers which consist of thin aluminum tubes (d = 6 mm), acting both as compression members for the structure, and as a mount for an ultra-light, vacuum-formed polyethylene terephthalate, 0,5 mm) carrying the OPV modules on its upper side.
