The ESS Price Forecasting Report provides an in-depth five-year forecast for the price of a DC battery container, including battery cells, modules, racking, and additional balance of system needed for a containerized battery system.

The quarterly published Energy Storage STPR covers global and regional supply chain analysis, technology trends, and regional policy analysis. This quarter the focus is on new efforts for stackable BESS technology, the potential for non-lithium-ion technology as a tariff solution, and insights from a battery fire safety expert on myths vs. reality and best practices.

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.

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.

Christian Roselund, Intertek CEA’s Senior Policy Analyst, joins the SunCast Podcast to discuss the new House budget bill threats to solar.

In kWh Analytics’ latest Solar Risk Assessment report, Intertek CEA highlights that fire suppression system issues were identified in 28% of energy storage systems during factory inspections.

George Touloupas, Vice President of ESG and New Services at Intertek CEA, and Huatian Xu, Intertek CEA’s Director of Technology and Quality, analyze the April 2025 results from the pv magazine test outdoor installation in Yinchuan, China.

Solar modules are growing larger, thinner, and more powerful—but a recurring issue is emerging worldwide: broken glass. According to Intertek CEA’s Joerg Althaus, these cracks often start near the frame or clamps and can spread from a few panels to thousands, without any obvious cause like hail or mishandling.

Sonnedix, an international renewable energy producer, engaged Clean Energy Associates (CEA) to conduct commissioning inspections for its recently-installed solar projects. The goal of the work was to ensure that their contractor (EPC) followed the agreed scope of work. CEA provided independent verification that all work met stringent quality and safety standards.

As solar deployments continue to grow, so do the risks of module failures, underperformance, and safety hazards—many of which are preventable with the right knowledge. In this Solar Power World webinar, Intertek CEA Senior Engineering Managers Claire Kearns-McCoy and Ankil Sanghvi explain how understanding common pitfalls—from thermal events to electrical failures—can help developers avoid millions in losses.

This Interim Update of the Energy Storage System (ESS) Q1 2025 Price Forecasting Report highlights how newly imposed U.S. tariffs are reshaping the cost landscape for imported battery systems and components from China.

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.

The latest Energy Storage System (ESS) Supplier Market Intelligence Report finds that the market landscape for lithium-ion batteries continues to evolve, and supplier strategy is shifting rapidly in response to the tariffs announced by the United States under the Trump administration, particularly on China, and persistently low prices.

In this PV Tech article, Martin Meyers explores how the Inflation Reduction Act is reshaping U.S. solar manufacturing incentives and project economics. He highlights the evolving challenges developers face in navigating domestic content requirements and qualifying for bonus tax credits.

In this Energy Storage News article, CEA’s Senior Energy Storage Engineer Ahn Vu explores how alternative technologies to lithium-ion are unlikely to oust the incumbent anytime soon.

SEG Solar and Astronergy supplied new tunnel oxide passivated contact (TOPCon) modules, alongside an n-type back-contact sample from Aiko, for installation in the first week of March 2025. To add these new products to the comparison table in these results, we removed the production data from before March 7. Due to downtime for system upgrades, we also did not capture data for three days in March and therefore had to remove those days from the total energy yield calculation. Finally, three products using 210 mm square cells were removed from the data, as we identified anomalies in the production figures caused by the maximum power point tracking algorithm. The data from those products will be reported again as soon as the issues are resolved.

You can build an entire energy infrastructure project and still wait years to flip the switch. In today’s market, it’s not the modules or permitting that cause the longest delays. Clean Energy Associates’ Eddy Ji explains how high demand for transformers and other essential grid infrastructure equipment is slowing things down.

CEA conducted factory, pre-installation, and post-installation inspections for 1 GW solar PV portfolio in Chile. The goal was to assess module quality and identify defects from manufacturing to installation. The inspections focused on electroluminescence (EL) imaging and visual inspection to detect potential soldering issues, microcracks, and other module degradation mechanisms. A total of 8,520 images were taken.

A solar project developer engaged CEA to investigate widespread glass breakage across multiple PV sites. CEA conducted comprehensive on-site inspections and structural assessments, which pointed to possible issues related to module durability and mounting system compatibility.
