Here we present results highlighting the differences that soiling and cleaning have on concentrated photovoltaic arrays (CPV) specifically focusing on ultra high concentration, >1000 Suns, photovoltaic (UHCPV) arrays in a desert environment. Soiling

We describe a process for increasing power efficiency of concentrator photovoltaic systems by optimizing the lens-to-cell spacing. We find that there is an optimum defocus position with improved power output and reduced sensitivity to pointing errors
