Chris has also noticed a greater power output with the MiaSolé panels. Even though the MiaSolé panels are rated at a lower wattage than the glass panels (210 watts vs. 250 watts) they generate more power (20 amps vs. 16 amps). His theory is that the MiaSolé panels are able to perform better with the inevitable partial shading from masts, sails or the radar dome than the previous solution.
Chris' theory is not wrong. The MiaSolé panels do perform better in partial shade because they have a bypass diode for every two solar cells while the glass panels he had before had one diode per entire row of solar cells. When a solar cell is shaded, much like a Christmas light that's out on a string, it will disrupt power to the other cells it's connected to. Because of the increased number of diodes, partial shading has less effect on the output of the MiaSolé panels than traditional silicon panels.
