Thornova Solar joins the industry’s most elite performers in independent reliability benchmarking.
Fremont, CA — June 3, 2026 — Thornova Solar today announced that its Tangra M PRO 585–605W module has been awarded “Overall Highest Achiever” status in the Renewable Energy Test Center (RETC) PV Module Index (PVMI) report, highlighting exceptional performance across reliability, quality, and power output testing.
The recognition places Thornova Solar among a select group of manufacturers demonstrating top-tier consistency across RETC’s rigorous, 12-month beyond-certification testing regime. The PVMI is widely regarded as one of the industry’s most stringent independent benchmarking programs, evaluating modules across multiple accelerated stress sequences designed to simulate long-term field exposure, with only a small fraction of tested products meeting the criteria for the report’s highest designation. According to RETC, The “Overall Highest Achiever” designation represents “the best of the best” among globally tested PV module products.
The Tangra M PRO series, rated between 585W and 605W, achieved high marks across key PVMI disciplines, including mechanical durability, thermal cycling stability, and power degradation resistance. The result reflects Thornova Solar’s continued investment in advanced cell architecture and high-reliability module design, reinforcing its suitability for bankable solar projects in global markets.
RETC statement
A spokesperson for RETC congratulated Thornova Solar on the achievement:
“We congratulate Thornova Solar on earning the ‘Overall Highest Achiever’ designation in the PV Module Index. This recognition reflects the Tangra M PRO 585–605W’s strong and consistent performance across RETC’s rigorous reliability, performance, and quality testing protocols. Modules that reach this level demonstrate exceptional engineering integrity and long-term operational confidence for project stakeholders.”
