EU PVSEC 2026 reflections: designing the scale-up journey
September 2026 · EU PVSEC, Rotterdam
Closing EU PVSEC 2026, Verónica Bermúdez Benito reflected on scale-up as a journey that must be designed from the outset. Technology performance can advance while process robustness, qualification, supply chains, customer commitment or financing remain insufficiently developed.
Define what the next scale must demonstrate
A pilot line, a repeatable product and a deployment accepted by a customer represent different demonstrations. Before increasing scale, the practical question is which assumptions must become evidence, under what conditions, and who needs that evidence to make a decision.
For manufacturing, that may mean measuring variability across preparations, lots or operating shifts, alongside throughput, yield and rejected units. For deployment, it means understanding integration, operating conditions, qualification and the ability to deliver and maintain the product. These are examples of evidence questions, not a universal checklist for every technology.
Coordinate the dependencies
Technical, industrial and commercial readiness develop through connected decisions. Product specifications affect manufacturing requirements. The intended application shapes qualification. Customer economics and delivery capability influence which route to market is credible.
BERBETIN’s Scale Readiness Level approach is used alongside technology readiness to make these dependencies and evidence gaps explicit. The assessment is scoped to the product, application and decision being considered.
