Kiwa PVEL and Kiwa PI Berlin Release White Paper Defining PV Module Quality Requirements

Kiwa, a world leader in Testing, Inspection, and Certification (TIC) services, is proud to announce the release of a new white paper developed as a collaboration between solar business groups Kiwa PVEL and Kiwa PI Berlin. This white paper introduces a comprehensive set of new photovoltaic (PV) module quality requirements aimed at enhancing the reliability and performance of solar sites worldwide.

The white paper, titled “Raising the Bar: Defining acceptable levels of quality for PV modules” addresses critical industry challenges by assigning benchmarks for evaluating the quality of solar modules through extended reliability Product Qualification Program (PQP) testing, Pre-Shipment Inspection (PSI), Batch Testing and Ongoing Reliability Monitoring (ORM).

“This white paper highlights key aspects for module procurement and displays our commitment in pushing the industry to higher levels of quality,” said Terry Jester, Managing Director for North America at Kiwa PI Berlin. “We believe our updated guidance will be instrumental in advancing the solar industry and safeguarding renewable energy investments worldwide.”

Maintaining high quality PV modules is essential for the sustainable growth of the industry. Kiwa PVEL and Kiwa PI Berlin, recognized for their expertise in solar testing, in-factory inspections and technical advisory, have collaborated to provide a comprehensive guide that outlines heightened approaches to increase module durability and long-term performance via testing and inspections.

Key Highlights of the White Paper include:

• Official guidance on PQP result acceptance including defined pass/fail thresholds.
• Pre-Shipment Inspection test scope, sample size and Acceptable Quality Level (AQL) requirements.
• Recommendations for Batch Testing and Ongoing Reliability Monitoring, including test protocols, test frequency and result expectations.

“We have used the past years of PQP data to create clear direction for the industry on what test results should be considered acceptable” commented Tristan Erion-Lorico, VP of Sales and Marketing at Kiwa PVEL. “This is the first time Kiwa PVEL has publicly provided this guidance, which will surely lead to more reliable PV module designs and material selection.”
