Detailed Solution
Download Solution PDF- The use of bypass diodes allows a series (called a string) of connected cells or panels to continue supplying power at a reduced voltage rather than no power at all.
- Bypass diodes are connected in reverse bias between solar cells (or panel) positive and negative output terminals and have no effect on its output.
- The bypass diodes’ function is to eliminate the hot-spot phenomena which can damage the PV cells and even cause a fire if the light hitting the surface of the PV cells in a module is not uniform.
