Kiwa PVEL and Kiwa PI Berlin printed a white paper that makes use of current module testing and in-factory information to information the most effective use of check and inspection metrics. The position goals to make sure that photo voltaic modules meet acceptable high quality requirements.
PV testing labs Kiwa PVEL and Kiwa PI Berlin have collaborated on a white paper outlining methods to use testing and inspection to enhance the sturdiness and long-term efficiency of photo voltaic modules.
The white paper, “Raising the Bar: Defining acceptable high quality ranges for PV modules,” assigns benchmarks for evaluating photo voltaic module high quality via the long-term reliability Product Qualification Program (PQP ) testing, Pre-Shipment Inspection (PSI), batch testing, and Ongoing. Reliability Monitoring (ORM). It says these metrics “present a complete framework for making certain that PV modules meet the very best requirements of high quality and reliability.”
The paper consists of steering on PQP acceptance thresholds from Kiwa PVEL primarily based on the assorted check outcomes seen via this system over the previous few years. The steering is separate from the PQP check, which gives steering on what qualifies as a “clear move,” “conditional move,” and “clear fail.”
“We used earlier years of PQP information to create clear route for the business on what check outcomes must be thought-about acceptable,” stated Tristan Erion-Lorico, VP of gross sales and advertising at Kiwa PVEL . “This is the primary time Kiwa PVEL has publicly offered this steering, which is able to absolutely result in extra dependable PV module designs and materials choice.”
The white paper additionally coated PSI and revealed that solely 76 out of 774 analyzed batches of photo voltaic modules handed inspection with out defects.
Analysis by Kiwa PI Berlin recognized electroluminescence defects as the most typical subject, primarily resulting from microcracks, weak soldering, cell contamination, finger breakage, and short-circuited cells. Frame defects are the second most continuously noticed drawback.
It additionally affords suggestions for evaluating PV modules at totally different manufacturing phases and batch sizes utilizing batch testing and ORM. It outlines check protocols, frequencies, and acceptance thresholds for each metrics.
“This white paper highlights key features for module procurement and demonstrates our dedication to push the business to increased ranges of high quality,” stated Terry Jester, managing director for North America at Kiwa PI Berlin. . “We consider our up to date steering shall be instrumental in advancing the photo voltaic business and defending renewable vitality investments world wide.”
Kiwa PVEL and Kiwa PI Berlin united underneath the Kiwa model earlier this yr. The information follows the discharge of Kiwa PVEL’s tenth PV Module Reliability Scorecard.
