Different Degradation Modes of PV Modules: An Overview
(b) Light-Induced Degradation (LID): LID is the loss of power incurred during the infant stage of a PV module due to the initial exposure to sunlight.LID occurs in amorphous as well as crystalline silicon solar cells. It is more severe in a-Si solar cells and degrades its efficiency by up to 30% [] and better described as "Staebler-Wronski" effect.

Hotspot Effect on Solar Panels: Causes and Solutions
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.

Why and how do solar panels degrade? — RatedPower
Interaction between the crystalline silicon cells on the panel with the outside environment. LID can last days or over a week. Direct light-induced degradation (DLID). Direct exposure to sunlight during the initial setup period can cause the electronics within the photovoltaic cells to warp or buckle from the heat. DLID can last a few hours.
Solar array mismatch losses: What are they, How to prevent them?
The solar array mismatch loss is expressed in the percentage of the total array output. For example, if an array has a mismatch loss of 0.5% and the total array output is 1000 W, then the mismatch loss would be 0.005 kW (0.5% x 1000W). The solar array ...
