Thornova Solar’s high-efficiency Tangra M Pro 580Wp N-Type bifacial module has successfully passed all major Kiwa PVEL reliability tests — demonstrating less than 2% power degradation in each sequence. The results confirm the module’s outstanding mechanical and environmental durability in demanding environments.

Fremont, CA, USA – July 31, 2025 – Thornova Solar is pleased to announce that its Tangra M Pro 580Wp N-Type bifacial dual-glass modules have successfully completed the full suite of reliability tests conducted by Kiwa PVEL, one of the industry’s most respected third-party PV testing laboratories.

The modules, produced at Thornova's Indonesia facility for the U.S. market, demonstrated exceptional stability with less than 2% degradation in all test categories — a strong indicator of long-term performance and reliability. The same Bill of Materials used for this batch is available for production at Thornova’s other facilities serving the EMEA and APAC regions.

Passed Kiwa PVEL Test Sequences:

· TC600 – Thermal Cycling (600 cycles between -40°C and +85°C)

· DH2000 – Damp Heat (2000 hours in high humidity and temperature)

· MSS – Mechanical Stress Sequence

· PID192 (-) and PID192 (+) – Potential Induced Degradation (negative & positive bias)

· LETID324 – Light and Elevated Temperature-Induced Degradation

· UVID120 – Ultraviolet-Induced Degradation (120 kWh/m² UV dose)

“These outstanding results validate the engineering strength behind our Tangra M Pro platform,” said Andrea Bodenhagen, Global Branding Director at Thornova Solar. “Our customers can feel confident that these modules are built not only for high efficiency but for long-term resilience in the field.”

Engineered for High-Demand Environments

The Tangra M Pro 580 N-Type module combines bifacial N-type cell technology with a robust dual-glass construction, delivering superior performance in both harsh weather and high-temperature conditions. Backed by a 30-year linear performance warranty, the module offers excellent low-irradiance response, a low thermal coefficient, and strong resistance to PID, LETID, and UV exposure — as validated by Kiwa PVEL's testing.
