Flexi panels are made with UniSolar triple-junction cells, which perform especially well under the low light levels typically found in the UK. Each cell is composed of three semiconductor junctions stacked on top of each other. The bottom cell absorbs the red light; the middle cell absorbs the yellow/green light and the top cell absorbs the blue light. This spectrum splitting capability is the key to higher efficiency. Unlike crystalline technologies, Flexi panels do not suffer reduced power output at higher temperatures.
There is a blocking diode within each potted junction box, preventing battery discharge into the panel. 10W and 32W panels have bypass diodes across each cell, so the modules continue to produce power even when partially shaded.
