solar pixel

detail of ‘piksols’

swiss-based drzach & suchy (drzach is an architect in basel, suchy is a cryptographer, software engineer working in zurich) have designed ‘piksol’, a solar cell pixel which enables one to create arbitrary patterns and images on sun facing building facades. it represents a single pixel of an image, so when multiple ‘piksols’ are combined in a desired arrangement, they provide a visual design, while at the same time exercising the capabilities of collecting solar energy. this combination allows for both an aesthetically interesting and environmentally-friendly facade design.

drzach & suchy have built a small prototype of a shadow casting panel which gives you an idea of how the ‘piksols’ could be realized on a facade.

solar pixel a single ‘piksol’when ‘piksols’ are attached to the facade of a building, they cast a shadow represented in the form of a black pixel of the image / pattern which will be visible. an observer standing in front of a building decorated by ‘piksols’ would not see the solar cells at all. on a cloudy day when there is no direct sunlight the pattern would hardly be visible.

  • Isn’t it a huge waste of money to place solar collectors at random angles based on the desire to create a pretty picture.

  • Pretty, a nice way of collecting solar energy albeit not the most efficient. Looks similar to Solar Ivy http://www.s-m-i-t.com/.
