pv magazine Webinar - Learning from PV Modules Manufacturing Nonconformities
In this pv magazine Webinar we examine nonconformities reported during the PV module manufacturing process. We define manufacturing nonconformities, analyze which ones are frequently found in production, and investigate on their distribution along the manufacturing line.


PV Magazine Webinar | Alleviating Battery Storage Growing Pains Through Quality Assurance
STS outlines the key takeaways observed across more than 2 GW of inspected hardware, to provide an illustration of common areas of issue. The discussion also includes an overview of STS’ hierarchy of priorities when it comes to assessing one’s own manufacturing processes for consistent quality. Fluence also joined this webinar for the topic discussion.


PV Magazine Webinar | Purchasing modules in 2022 – What should be in your purchase contract?
This webinar discusses what elements should be placed into a purchase agreement, from adequate quality requirements to emerging supply chain requirements, and what support you can get from an accredited inspection body to ensure high quality PV module manufacturing and delivery.


PV-Tech Webinar: Supply Chain Traceability
Frédéric Dross, STS, as an invited guest, explained how supply chain audits help module buyers evaluate the ability of manufacturers to demonstrate traceability and transparency of their supply chains.

PV ModuleTech 2021-Best Practices QAQC for Superior Bankability
The best practices for superior bankability presented by Frédéric Dross,STS at PV ModuleTech 2021.
The best practices for superior bankability are:
- Assessment of Suppliers/Products
- Qualification of Suppliers/Products
- Control and Issuance of a Certificate of Conformity
For the “Control” phase during manufacturing, the recommendations are:
- Use only accredited inspection bodies
- Use a widely-accepted QA/QC “Standard” for criteria and requirements
- Be present in factory 24/7


PV ModuleTech2019 - STS Interview
STS President, Alexandre talks about where bifacial PV modules make most sense, what makes module manufacturers bankable and the technologies he expects to dominate utility-scale solar in 2020. Also discussed is which module manufacturing markets (outside China) will be key in 2020 and why.
