Sun-Tracking Photovoltaic System
The 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.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
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.
OPERATION / FLOW / INTERACTION:
The photovoltaic aps panel is able to deform smoothly and quickly through a polymer capable of changing its structure at the passage of electricity, while the structure just like a skeleton supports electropolimer, which makes him like a lightweight muscle and allows him to move towards the light.
PROJECT DURATION AND LOCATION:
Started in September 2013 and finisched in JANUARY 2014 in NAPLES
PRODUCTION / REALIZATION TECHNOLOGY:
Panels are hexagonal and divided into 6 segments of electroactive polymer (eap) that deform at very low electric charges, creating the follower movement and rising up to 5 centimeters.
The photovoltaic part is a deposition of cgis nanoparticles, a thin film similar to an ink that adapts to the flexible substrate.
The eap layer with cigs one are protected by an addictional ultrathin and clear layer, a flexible glass of the latest generation, the willow glass.
SPECIFICATIONS / TECHNICAL PROPERTIES:
Width 159 x Depth 1 x Height 139

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
