Does the tape need to be UL listed? Anything else that pertains? - Peter Peter T.

The SolarWorld SW230 is comprised of one series string of cells. It acts somewhat like there are three strings because of the bypass diodes. If you shade one cell of one group, the bypass diodes kick in and allow the module to continue to produce power but at a reduced level. Our test showed that if the short edge is shaded for more than half of a cell width on the narrow edge, the total output caved. The same shading on the long edge reduced output minimally.
