Advanced PV systems for Mediterranean climate

The Mediterranean region exhibits significant potential for the application of photovoltaic (PV) systems. The advanced system, based on a one-axis passive tracker with soft concentration developed in the project, appears to be a very attractive technology as its energy gain is significantly higher than for a fixed system.

Scientific investigations are consistently undertaken by the PV industry in their quest to develop the most efficient PV systems. The concept of one-axis passive tracking together with a soft concentration, obtained by means of reflective surfaces, seems to be very attractive because of the increase in energy output. It was also expected that this system could also result in a reduction in the cost of PV per kWh. That would constitute a contribution to the diffusion of PV for stand-alone or grid-connected systems especially for sites well favoured by direct solar radiation. One of the aims of the project was the use of commercial, flat plated PV module, with soft concentrators, and a Passive Thermohydraulic Drive (PTD), developed by ZSW to perform the passive tracking in this new, advanced system. Comparative performance with a tilting fixed system was also investigated.
