Luminous "Solar Flags" at Castello Doria in Porto Venere (Italy)
In the inner courtyard of the listed monument Castello Doria in Porto Venere, three "solar flags" have been mounted hanging on steel wires, in each of six wall arches. Intervention in the historical walls was minimised by using existing holes to fix the wires.
The modules are transparent, slightly curved acrylic glass components with imbedded semitransparent grey solar cells. They are luminous because of integrated light emitting diodes (LEDs).
The power generated by the 18 "solar flags" is stored in a battery and used to light up the modules at night.
Both the modules themselves and the integrated lighting may also be produced in different colours. The possible applications of the "solar flags" are extremely varied. Since any number of them can be added and mounted in various ways and on various sub-structures, they are just as suited for the - also temporary - design of public squares as for the use in "solar trees" or "luminous canopies".
The installation, erected in 2004, is equipped with an automatic data logging system that measures power generation and consumption and can be used to call up and check the data at any time.
