Starting with the PVC modules, SANYO produces the most powerful solar panel in the world, with the highest available solar energy conversion efficiency of 22.3%. This is over 5% higher than the industry average. The technology that produces this increase output is called HIT, Heterojunction with Intrinsic Thin layer for those who like to unravel acronyms. The panels are made up of layers of crystalline silicone wafers and thin amorphous silicon. The HIT PVC modules have a much smaller footprint and lighter weight for the equivalent power output than ordinary panels.
