1. 1. Study of defects in PV modules : UV fluorescence and Thermographic photography for Photovoltaics (PV) Field Application

   Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Författare :Sophie Nylund; Zahra Barbari; [2019]
   Nyckelord :UV fluorescence; IR thermography; defects in PV modules; delamination; discoloration; hotspots; snail trails; cracks; fault in bypass diode; non-functioning cell in PV;

   Sammanfattning : For a PV plant it is of fundamental importance that the operation of the PV modules is free from faults or at least that the faults can be detected early, to ensure efficient electricity production. Some defects such as cracks can be seen in visible light while microcracks and damage to the silicon material can only be seen through special lighting. LÄS MER

3. 2. Aerial Thermography Inspections in Large-Scale PV Plants

   Master-uppsats, Högskolan Dalarna/Energiteknik

   Sammanfattning : In order to successfully compete against the use of fossil fuels to generate electricity, one of the challenges in the photovoltaic (PV) business currently in focus is on the asset management of large PV plants, in which developing control techniques to prognosticate and evaluate the future energy performance will be essential. Infrared thermography inspections can give meaningful support to assess the quality and performance of PV modules. LÄS MER
