High concentration photovoltaic system with parallel kinematic solar tracker

The paper introduces a high concentration photovoltaic system developed at Politecnico di Torino. The system includes a new kind of solar tracker, based on a parallel kinematic mechanism, some high concentration photovoltaic modules and a heat recovery circuit intended for recovering heat from the chilling plant. The paper in its first part describes in deep the design of the tracker and the control strategy used to drive it. In the second part the construction of a 2,8 kWp prototype is described and some results about experimental tests are shown
