ADVANCED PHOTOVOLTAIC SYSTEM2014 - NaplesThe panel is deformed according to the position of the sun, inspired by the movement of sunflower and its phototropism. As the cells of sunflower spread out and create movement toward the sun, so the panel material deforms in the chosen direction. Its movement is fluid and organic such as that of a muscle. The hexagonal shape is inspired by the observation of bees and their cells that starts since ancient times and the characteristic of the hexagon tessellate the surface using fewer edges.A new concept of photovoltaic system wich follow the sun in every moment of a day and of the year: Just like an evergreen sunflower without heavy machinery to generate movement. Ultra thin and ultra light, panel takes advantage of innovative an sustainable materials to create an organic and fluid movement, that reminds a muscle wich can follow the sun.The research begins with the observation of existing in nature heliotropic system and the need to have for the future PV systems not bulky, recyclable, light and modular that integrate harmoniously within urban contexts. Hence the APS project inspired by the enzymes present in the stem of the sunflower and hexagonal structures that are found in nature.Research materials and their symbiosis was a challenge that we have been able to deal well thanks to the numerous experiments and knowledge gained in the field of smart materials.
