The Invisible Killer of PV Modules: Sand & Dust — How Do We Test It?
In desert, gobi, or coastal regions, photovoltaic modules are constantly exposed to harsh wind and dust.
Over time, fine particles abrade the module surface, reducing power output and shortening service life.
So how can we verify reliability in advance?
Zealwe Tech’s Sand & Dust Chamber is designed to simulate real-world sandstorm conditions —
with wind speeds up to 30 m/s, dust concentrations of 0–20 g/m³, temperature range 0–200 °C, and humidity 0–100 % RH.
It enables PV testing laboratories and module manufacturers to conduct IEC 60068 standard tests, ensuring accurate environmental simulation and long-term performance validation.
Through scientific testing, we make sure every solar module stands the test of time and environment.
