Early degradation is observed in m-C-Si modules of a photovoltaic system installed in a Himalayan location.
- class="label">•
Snail trails, single cell browning and junction box failure are observed in all the PV modules.
- class="label">•
Degradation analysis is carried out by visual inspection, thermal imaging and I–V characteristic measurements.
