We are back with our series Enemies of Photovoltaics, this time to tell you about LeTID, a fairly new phenomenon and therefore less investigated compared to other defects such as PID or LID. LeTID (Light and Elevated Temperature Induced Degradation) describes the loss of performance of photovoltaic modules under certain circumstances.
In this installment we will go deeper into a serious defect that can be found in photovoltaic modules due to poor quality materials and/or handling: delamination.
The present and future hold great challenges for photovoltaic technology in terms of material quality, installation, operation and, finally, decommissioning. Photovoltaic technology is mature, but only if the industry responds adequately to the demands for secure and reliable supply can it establish itself as a major source of large-scale electricity.
Photovoltaic modules have a service life of at least 25 years; they can even perform up to 50 years and more. In order for them to provide their services in conditions of maximum performance and operational safety, they must be manufactured with top quality materials, following a meticulous process.
