Hail Durability Test

HDT

The Hail Durability Test program assesses the characteristics of the PV Modules and their BOM and constructions when subjected to installations in hail-prone regions. PV modules undergo a simulation of conservative wind speeds and are checked for their performance near the threshold of damage, just over the threshold (repairable damage), and at material failure. The HDT program maximizes test result confidence by using repeatable speeds & consistency in ice ball quality. The results are categorized by hail size, velocity, and the resulting kinetic energy (Ke).
