Solar Spline

A modern solar-sail combines sun protection with power generation

Universität and Kunsthochschule Kassel, Germany

Urban solar cloud

As climate change arrives, cities are getting hotter and hotter. Architects of the University of Kassel, Germany, offer a sustainable solution to this dilemma: the "Solar Spline" project. The ingenious design for sun protection in urban areas not only provides shade, it also produces clean energy for the city. Based on the typology of a traditional sun sail, the "Solar Spline" is composed of 300 printed photovoltaic modules. These are integrated into a resource-conserving, ultra-light construction. The result is a three-dimensional, seemingly free-floating solar cloud, whose photovoltaic cells may follow the sun's course. Shadow-provider, energy generator, architectural highlight: the Solar Spline will make our cities more appealing for the future.
