The purpose of this work is to improve the efficiency of PV plants and to solve the main limitations: the thermal drift which lowers the efficiency of the system, the availability of spaces for photovoltaic fields, the high cost of tracking systems. The proposed solution consists in building circular floating platforms on small basins and lakes, with a set of photovoltaic panels supported by a structure in polyethylene tubes and cooled with the basin water. The platform diameter ranges from 20 to 40 meters and has power from 25 to 100 kW. This Floating Tracking Cooling Concentrating (FTCC) System overcomes the limits quoted above and allows an annual yield considerably improved compared to a fixed ground plant. A careful use of plane reflectors is analyzed in detail and solutions to improve the system efficiency and to lower its cost are discussed.

Abstract
The purpose of this work is to improve the efficiency of PV plants and to solve the main limitations: the thermal drift which lowers the efficiency of the system, the availability of spaces for photovoltaic fields, the high cost of tracking systems. The proposed solution consists in building circular floating platforms on small basins and lakes, with a set of photovoltaic panels supported by a structure in polyethylene tubes and cooled with the basin water. The platform diameter ranges from 20 to 40 meters and has power from 25 to 100 kW. This Floating Tracking Cooling Concentrating (FTCC) System overcomes the limits quoted above and allows an annual yield considerably improved compared to a fixed ground plant. A careful use of plane reflectors is analyzed in detail and solutions to improve the system efficiency and to lower its cost are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
