Shoot an EL Baseline Before Winter — Snow Load, Freeze-Thaw Cycling and Cold Push Hidden Cracks Into Their High-Risk Season

For plants in snow-prone regions, winter is not a quiet season for the modules: static snow load, repeated freeze-thaw cycling and low-temperature embrittlement together make micro-cracks far more likely to form and to grow. This article explains the three mechanical stresses winter adds, why cold makes cracks more dangerous, and why a pre-winter EL baseline — made affordable by daytime UAV EL — draws a clean responsibility line and lets a spring re-shoot quantify exactly how much damage the winter added.
