Future of solar systems on lakes?

Floating solar systems: efficient and inexpensive

System from Scienza Industria Tecnologica creates up to 200 kilowatt peak

The Italian scientist Marco Rosa-Clot from the University of Florence http://unifi.it has developed a floating solar system. The owner of the company Scienza Industria Tecnologica http://scintec.it can avoid the disadvantages of conventional solar parks with the help of the so-called "Floating Tracking Cooling Concentrator". The photovoltaic panels are housed on round or rectangular floating bodies made of plastic tubes.

Innovative cooling

Due to the modular design, nominal outputs of 20 to 200 kilowatt peak are possible. The only one meter high and therefore barely visible systems can also be found on smaller, natural or artificial lakes. "With the help of a small electric motor, tracking and thus the optimal alignment of the system is guaranteed", Marco Rosa-Clot explains to pressetext.

"Another advantage is the permanent cooling via water nozzles, which prevents the system from overheating and allows an additional energy yield of more than ten percent." We are currently experimenting with two types of construction: One with panels and reflectors at an angle of 40 degrees each and the other with panels lying flat and reflectors attached to the sides at a 60-degree angle. "

With the latter solution, the energy yield increases by 60 to 70 percent, depending on the latitude. In addition, certain wind loads are simulated. With around 800 euros per kilowatt of peak output including the expenses for tracking and cooling, the system also allows comparatively low generation costs.

1.200 kilowatt hours a year

"While conventional systems have an annual output of 1.200 kilowatt hours, the FTCC achieves up to 2.000 kilowatt hours," says the Italian scientist. Scintec, founded by Marco Rosa-Clot and based in the technology park of Navacchio near Pisa, specializes in the manufacture of laser, environmental and sanitary technology. Scientific collaborations exist with the Italian research institutes Infn, Enea and Cnr as well as with Geneva’s CERN and the German Fraunhofer Institute.
