In this article, originally published in MESIA's Mid-year Solar Report 2025, Jeff Zwijack, Associate Director of Energy Storage at Intertek CEA, explains that most defects in battery energy storage systems arise during system-level integration rather than cell or module production.

This article highlights how Intertek CEA’s audit prevented defective battery cabinets from reaching a project site and exposed the supplier’s resale of unsafe equipment. The case underscores the importance of independent quality oversight.

Intertek CEA conducted quality audits at 70+ battery energy storage factories worldwide. Our data shows that in 2024 the vast majority of identified quality issues were at the system level.

This pv magazine webinar addresses the quality risks U.S. solar module buyers face due to increased warehousing and the emergence of new manufacturing facilities. Experts from Clean Energy Associates (CEA) will discuss the rise in warehoused modules, common storage-related risks, quality concerns in new manufacturing environments, and strategies to mitigate these issues

In this pv magazine article, George Touloupas, CEA’s Senior Director for Technology and Quality, reviews the quality assurance (QA) activity and methodologies used to ensure PV performance and emphasizes the importance of data-driven approaches and continuous monitoring.

In this Energy Storage webinar, Senior Policy Analyst Christian Roselund and Director of Energy Storage Market Intelligence Dan Finn-Foley analyze the potential impacts of U.S. policy changes on solar and battery storage.

In this pv magazine article, Jeff Zwijack, CEA’s Senior Manager for Energy Storage, explores the essential factors in selecting battery energy storage system (BESS) suppliers. With insights on supplier technology, quality assurance, and risk mitigation, Zwijack guides developers in building resilient, high-performance energy storage projects.

In this PV Tech article, Paul Wormser, Vice President of Technology, and Jake Edie, Vice President of Marketing, discuss the prevalence of soldering defects in solar panels, their impact on performance, and how robust quality assurance measures can help mitigate these risks.

In this webinar, CEA experts present findings on the most common issues seen in PV manufacturing factories, based on their latest inspection data.

Over the past 8 years, Intertek CEA has conducted more than 70,000 quality inspections in over 300 PV module factories. This report highlights concerning quality trends from the past few years in PV module manufacturing, which could lead to performance and safety risks in the field.

In this Solar Power World article, Jake Edie, Vice President of Marketing CEA, discusses the changing dynamics in the solar and energy storage markets and emphasizes the importance of maintaining high standards for quality in suppliers, products, project design, and installation to avoid costly issues.

In this pv magazine Webinar, Nicholas Hudson, Principal Engineer Engineering Services, and Jörg Althaus, Director Engineering and Quality Assurance Services, discuss common issues during production, what the downstream impact of those issues are, and action that can be taken to prevent these risks.

Large-scale, stationary battery energy storage systems (BESS) have rapidly become crucial components of modern power grids. With the increasing adoption of BESS, however, the risk of battery fires has increased, as Jeff Zwijack of Clean Energy Associates reports.

CEA’s Vice President of Marketing, Jake Edie, recently wrote an article in Renewable Energy World about the most surprising findings in clean energy and what developers and buyers will be watching most closely as 2024 unfolds.

Following extensive factory quality audits on over 30 GWh of energy storage projects over the past six years, Intertek CEA’s BESS Quality Risks Report highlights identified key defects and issues, including their causes and associated risks.

In this Energy-Storage.news webinar, CEA’s Battery Energy Storage System (BESS) experts will share essential lessons learned after performing factory quality audits on over 30GWh of BESS projects.

CEA's Director of Engineering Services, Jörg Althaus, joins pv magazine's Roundtables Europe 2023 to discuss how the industry is addressing the longevity, testing methods, and problem prevention of new solar panel technologies like TOPCon to safeguard investments.
