This means that the remaining cells have to compensate for the power loss of the shaded cells. So, the remaining cells will have to produce the same amount of power that was being produced by all 60 cells before the shadow. The output power of a single cell is calculated as follows: Output Power = Voltage x Current

Assessment of Photovoltaic Module Failures in the Field

Independent of climatic zones some PV module failures stand out with a high power loss if a PV system is affected by the failure. In the rank order of impact, these failures are potential induced degradation, failure of bypass diodes, cell cracks, and discolouration of the encapsulant (or pottant) material.
