Module Accelerated Sequential Testing (MAST)

The Benchmark in Solar Panel Testing

Materials matter when they consistently pass tests made to ensure durability and performance over time in a rigorous solar panel review standard called Module Accelerated Sequential Testing (MAST).
DuPont MAST is the new standard in solar panel testing.

Simulating real-world conditions, solar modules with DuPont materials are put through MAST and experience multiple aging stresses such as UV, heat, cold, moisture, and thermal cycling.
See what happens when materials aren’t tested.

The results are the reason that most solar panels in the world are made with DuPont materials.

Throughout the MAST process, sequential stress and climate tests are repeated, which mimic elements that could lead to substantial material failure. This is the best predictor of long-term field endurance and durability in solar panels.

SETTING THE STANDARDS

Dupont Photovoltaic Solutions has spent the past 40 years developing, refining, and standardizing accelerated testing protocols that correlate to long-term field performance.

 

By using proven materials and adopting MAST standards, failures and loss are minimized, but lasting value is ensured, day after day.
