In this article, Joerg Althaus of Intertek CEA explains why lost bypass diodes in PV modules are a hidden fire risk: they can pass standard factory and field inspections, yet create severe overheating when shading occurs.

Energy Storage News: To avoid pitfalls that can begin on the factory floor and extend well into operational lifetime, developers must sign well-structured guarantees and contracts to protect their BESS investments, writes Intertek CEA Senior Energy Storage Engineer Yilin Huang.

Energy Storage News: BESS performance guarantees are essential and ubiquitous, yet can be challenging to navigate, writes Intertek CEA Senior Energy Storage Engineer Yilin Huang.

The quarterly published PV STPR covers global and regional supply chain analysis, technology trends, and regional policy analysis.

The PV Price Forecasting Report provides independent market intelligence on changes in global supply chains and accurate forecasts for supply price scenarios based on technologies, materials, manufacturing regions and target markets, as well as supply and demand forecasts and analysis.

The latest Energy Storage System (ESS) Supplier Market Intelligence Report includes concise and standardized analyses of major LIB cell suppliers and BESS integrators, focusing on global production capacities, product portfolios, and notable projects.

The PV SMIP provides a comprehensive and unbiased analysis of the top PV module manufacturers in the world. It offers detailed insights into capacities, technology, and efficiency roadmaps, along with Manufacturing, Capacity, and Technology (MCT) ratings for each supplier.

Intertek CEA conducted quality audits at more than 90 Energy Storage System (ESS) factories worldwide. Our data shows that in 2025, more than 1 in 8 inspected ESS units had safety-critical issues relating to the battery management system, thermal management, or water ingress.

pv magazine: Over a 30-year asset life, corrosion can escalate into a structural, electrical, and fire safety risk that raises O&M costs, weakens resilience to extreme events, and can ultimately lead to premature decommissioning or full structural replacement, as advised by Intertek CEA’s Nicholas Hudson and Ankil Sanghvi.

In this Canary Media webinar, Intertek CEA Senior Policy Analyst Christian Roselund joins a panel of industry experts to break down how FEOC restrictions are being applied in practice, and what developers, investors, and manufacturers should be doing now.

The PV & ESS Inverter Report is an independent market intelligence report covering global inverter supply, pricing, technology, and policy dynamics across the solar and energy storage sectors.

PV Tech: Paul Wormser, Senior Vice President of Technology at Intertek CEA, outlines how ITC eligibility now hinges on traceability, documentation and verification. As rules tighten under H.R. 1, procurement must address counterparty risk, not just module performance, to secure tax equity confidence.

Energy Storage News: BESS safety issues become all too visible when it’s already too late, but a considered approach through the full lifecycle can mitigate these and many other risks, writes Sunny Rai from Intertek.

Over the past nine years, Intertek CEA has conducted more than 80,000 quality inspections in over 340 PV module factories. This report summarizes our 2025 data, which reveals rising soldering defect rates and emerging reliability risks as the industry shifts toward n-type products.

George Touloupas and Huatian Xu of Intertek CEA analyze the January 2026 results from the pv magazine test outdoor installations in Yinchuan, China, and Dammam, Saudi Arabia.
