Solar damage assessment often uses tools like drone infrared (IR) imaging or UV fluorescence (UVF). Each has its place—but EL brings unique advantages:

  • Exceptional sensitivity to microcracks – EL is one of the most effective methods for detecting fine cracks that are invisible to the naked eye or standard IR.
  • Not weather-dependent – Unlike UVF, EL does not require sunny conditions.
  • Field-deployable at scale – Modern EL systems let us test modules in the field, instead of removing panels for lab testing—saving time and cost.
  • Better cause attribution – Characteristic crack and defect patterns help distinguish between manufacturing issues, shipping/installation damage, and storm-related impacts—critical for warranties vs. insurance.

EL is often most powerful when combined with visual inspection, IV curve tracing, and drone IR to create a full, defensible picture of the damage.
