Designing solar collectors and optical fibers for daylighting

A system for solar energy exploitation, using optical collectors and fibres, has been applied for illumination of internal spaces. A demonstrator of the system has been experimented in a prestigious museum in Florence. The project has been called ýThe Sunflowersý for the property of solar collectors to track solar position during the day. Every Sunflower contains 8 solar collectors, each of which is coupled to an optical fibre and it is provided with a system for solar tracking.
