Rondine PV concentrators: Field results and progresses

摘要

In this work the experimental results of two pilot installations of 3.8 kWp and 4.9 kWp of Rondine PV concentrators installed in Italy are presented. These concentrating modules have a medium concentration level (25×) and employ silicon solar cells. The non-imaging optics of the concentrator allows for larger angular acceptance respect to many CPV modules, giving us the possibility to employ trackers for standard PV modules. The effect of soiling in these first installations is evaluated as well as their working conditions in different weather situations.
