Investigating Long‐Term Degradation and Defects of Solar Photovoltaic Modules in Tropical Climates: A Case Study of Malaysia

open access: yesIET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This study investigates the degradation of four monocrystalline silicon photovoltaic (PV) modules after nine years of outdoor exposure in Kuala Lumpur, Malaysia's tropical climate. Using visual inspection, electroluminescence, and electrical performance analyses, the modules exhibited an average power loss of 40.35%, primarily due to encapsulant ...

Power Losses From Series Resistances—Analysed Using Daylight Photoluminescence Imaging

open access: yesProgress in Photovoltaics: Research and Applications, Volume 33, Issue 11, Page 1247-1259, November 2025.
A novel method is proposed that uses daylight photoluminescence imaging, acquired with varied current extraction, to calculate the impact of series resistance defects on the maximum power that can be produced by a photovoltaic module. This contactless and automated technique supports quantitative in‐field degradation analysis, for large‐scale ...
