Astronergy has formalized a cooperation agreement with TÜV Rheinland to begin module qualification under the IEC TR 63279 technical report. This internationally recognized standard focuses on sequential and combined accelerated stress testing aimed at derisking PV modules in line with real-world reliability expectations.
The IEC TR 63279 testing protocol is among the most comprehensive in the PV industry, incorporating harsh environmental simulations to evaluate module durability under high temperature, high humidity, mechanical load and electrical stress conditions, its goal being to identify failure modes and ensure long-term field performance of modules deployed in extreme climates.
“Astronergy is fully committed to pushing the envelope of quality assurance,” commented Jack Zhou, its head of global product technical management. “The IEC TR 63279 standard is not yet mandatory, but we believe it represents the future of module qualification—one that aligns closely with the demands of utility-scale developers, EPCs and institutional investors.”
