The solar cells had a size of 7x7 mm operating with an efficiency of 35\% at 820{$\times$}. For these particular solar cells the warranty time for three locations, Golden (CO-USA), Madrid (Spain), and Tucson AZUSA), exhibits a 4 to 1 ratio, which affects the LCOE (Levelized Cost of Electricity) in an important way. In this work, we go a step further evaluating the influence of concentration and solar cell size on the warranty for a specific thermal design.} }
