Thornova Solar has announced that its Tangra M PRO 575-595W N-Type bifacial dual-glass module has achieved ‘Top Performer’ status in all seven reliability test categories evaluated by Kiwa PVEL as part of its internationally recognized PV Module Reliability Scorecard program. In addition, the same module successfully passed Kiwa PVEL’s enhanced 40 mm Hail Stress Sequence (HSS) test, further validating its resilience under increasingly extreme weather conditions.
The Tangra module demonstrated exceptional performance throughout the Product Qualification Program (PQP), including Thermal Cycling, Damp Heat, Mechanical Stress Sequence, Humidity Freeze, PID, LID + LETID and UV-induced degradation testing.
The HSS test, designed to evaluate module durability against severe hail impacts exceeding standard IEC requirements, subjects modules to high-energy impacts from 40 mm laboratory-manufactured ice balls travelling at terminal velocity to assess resistance against glass breakage, cell cracking and long-term power degradation.
Global Branding Director Andrea Bodenhagen commented: “We are delighted to see our Tangra M PRO 575-595W module recognized as a Top Performer across all seven Kiwa PVEL reliability categories, while also successfully completing the enhanced 40 mm hail test. These independent test results are particularly important for customers in regions exposed to severe weather events. They validate the strength of our engineering, manufacturing quality and material selection and demonstrate our commitment to delivering modules that perform reliably for 30 years.”
Tristan Erion-Lorico, VP of Sales and Marketing at Kiwa PVEL, added: “Congratulations to Thornova Solar on achieving Top Performer status across all seven evaluated reliability categories. The additional successful completion of the enhanced hail stress testing further highlights the company’s commitment to delivering durable, high-quality PV modules capable of performing under challenging environmental conditions.”
