Understanding the critical importance of testing to ensure durability and performance over time, DuPont has introduced a rigorous new solar panel testing standard called Module Accelerated Sequential Testing (MAST). MAST simulates real-world conditions, combining multiple aging stresses such as UV, heat, cold, moisture, and thermal cycling and applying them to the same module.
With MAST, sequential tests are repeated, mimicking field degradation not detected by single stress tests and current industry standards. It is proven to be the best predictor of long-term reliability, due to the thoroughness and prolonged aging stresses materials are subjected to in real world environments, including:
- 1000 Hours in a Humidity Chamber (amounts to >25+ years worth of stress)
- 600 Thermal Stress Cycles (mimics thermal stresses seen in the field)
- 1676 Hours in a UVX Chamber (Amounts to ~20 years desert dose of UV)
Tedlar® Backsheets Subjected to MAST to Ensure Long Term Performance
Materials Matter™ – DuPont™ Tedlar® PVF film-based backsheets have passed DuPont Module Accelerated Sequential Tests, offering the optimal balance of properties for weatherability, adhesion, and mechanical strength.
