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 quarterly published PV STPR covers global and regional supply chain analysis, technology trends, and regional policy analysis through early July 2025. 

In this PV Magazine article, Intertek CEA's engineering experts highlight how overlooked site-specific challenges such as poor soil conditions, flash floods, complex terrain, and extreme wind loading in Southeast Asia can derail solar projects if not addressed early through rigorous engineering and civil due diligence.

In this pv magazine Webinar, Intertek CEA’s supply chain experts—George Touloupas, Vice President of ESG & New Services, and Senior Project Managers Zhuo Chen and Nicola Licata—outline key ESG risks and share best practices for documenting and mitigating them.

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.

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

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.

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.

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.

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.

At the end of February 2025, three new samples - two tunnel oxide passivated contact (TOPCon) samples from SEG Solar and Astronergy and our first n-type back contact sample from Aiko – arrived in Yinchuan and were installed at the beginning of March. The outdoor data for these will be published next month.

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
