All activities proceed in close collaboration with CENER staff throughout. Infrastructure access follows a hybrid model: an initial 5-day on-site phase to define objectives, prepare samples, and launch testing, followed by 10 days of remote access during which CENER personnel conduct characterization, ageing tests, and results analysis, culminating in a final report for the user. Total duration can be adjusted according to the experiment’s specific scope. Backed by a longstanding track record as an IEC-accredited laboratory, the user support team brings deep expertise in indoor characterization and testing, covering commercial certification, performance evaluation, durability testing, and degradation analysis for both individual PV modules and full power plants.
