Kiwa PI Berlin launched its newest report reviewing the standard of photo voltaic panel producers, noting that new manufacturing areas (particularly the US) report increased manufacturing errors.
“The 2026 PV Module Manufacturing Quality Report” summarizes Kiwa PI Berlin’s high quality assurance findings from manufacturing unit audits, manufacturing oversight and pre-shipment inspections. The group discovered new defect patterns rising in high-impact processes, together with layup precision, lamination integrity and junction field meeting. These failures present weak spot within the panel producer’s means to handle bills-of-materials and course of controls.
Kiwa PI Berlin famous that U.S. factories present the best crucial and main high quality points; the Center East and Africa present increased quantities of defects; whereas Vietnam and Indonesia carry out strongest.
Lamination points — bubbles and edge delamination — are main defects seen at module manufacturing amenities. Improper encapsulant storage and insufficient lamination course of management had been recognized as the first root causes.
“The adoption of superior cell architectures, regional manufacturing incentives and evolving compliance frameworks will reshape manufacturing landscapes. It’s a authentic problem to fabricate many hundreds of thousands of PV modules in dozens of latest and rising factories utilizing lots of of BOM mixtures,” Kiwa PI Berlin contributors stated within the report. “By integrating data-driven QA practices into procurement and undertaking execution, stakeholders can’t solely navigate these complexities but in addition strengthen PV’s position as a cornerstone of world vitality transition. With collaboration, transparency and dedication to high quality, the business is well-equipped to ship protected, dependable, and sustainable solar energy for many years to return.”
