PV Evolution Labs (PVEL), an impartial check lab for the photo voltaic trade, has upgraded the corporate’s suite of prolonged reliability and efficiency assessments, the Product Qualification Program (PQP).
PVEL established the PQP in 2012 to offer empirical knowledge for PV module benchmarking and project-level power yield and monetary fashions, and to assist acknowledge top-performing PV modules. PQP testing additionally helps inform the corporate’s annual PV Module Reliability Scorecard, which offers actionable insights for PV module procurement based mostly on knowledge from PVEL’s testing.
“The module shopping for panorama has modified dramatically lately with developments in module know-how and new gamers coming into the market, and in response, PVEL has targeted our globally-acclaimed check program on addressing these adjustments,” mentioned PVEL’s Tristan Erion-Lorico.
“The enhancements we’ve made on this PQP replace incorporate important suggestions from our downstream companions, analysis institutes, module and part producers, and our personal check outcomes, protecting the PVEL PQP on the forefront of the rising demand for PV module procurement due diligence,” he provides.
Notable updates to the PQP embody the next:
- a brand new check to handle considerations round Ultraviolet Induced Degradation (UVID);
- refocusing the Hail Stress Sequence (HSS) on figuring out the brink of glass breakage;
- modifying the Mechanical Stress Sequence (MSS) to focus on module mechanical sturdiness considerations; and
- streamlining processes for Gentle Induced Degradation (LID), Damp Warmth (DH), Gentle and Elevated Temperature Induced Degradation (LETID), and Backsheet Sturdiness Sequence (BDS) testing.
Participation in PVEL’s PQP is voluntary for producers, and solely top-performing module mannequin sorts are named within the annual PVEL Scorecard. Up to now, PVEL has examined over 600 BOMs from greater than 70 producers for the PV Module PQP.
