Ideation: City Walk

In a short presentation, we examined two different types of photovoltaic panels. The first panel is a foldable photovoltaic system that is often used for camping.

Our creative assistant Andi Wagner introduced us to this panel as a means of generating mobile energy at trade fairs or events. In combination with a battery, a small exhibition stand including lighting can be independently powered. Without an additional battery, however, this would hardly be possible. The foldable panel can be folded up, stored in a bag and easily transported. The other panel is a classic “balcony power plant” that is available in hardware stores and is usually installed on building roofs in the form of larger systems. This is a photovoltaic module in a standardised size, which is sold together with an inverter and a connection plug. The inverter enables the solar energy generated (direct current) to be fed directly into the household‘s electrical circuit. By comparing the two modules, their respective areas of application were illustrated and a clear difference in their performance was demonstrated. The presentation of solar modules was followed by a walk around the city. During this tour, we were asked to explore the surrounding area for potential ‘solar gaps’ areas where a photovoltaic module could be installed. The task was to document these potential locations with cameras and later compile them in a presentation. The students split into small groups to search for suitable areas for photovoltaic modules. They were free to choose the area they wanted to explore, with most groups exploring the area within walking distance of our university. This resulted in some exciting photographs and observations, which led to new ideas for the project.
