In the first edition of PV Tech Power ten years ago, our cover article looked at the issue of PV module quality, which had come to the fore after a period of heavy cost-cutting in the industry. Following a decade of technological innovation, the overwhelming dominance of Chinese manufacturers and a global explosion in solar capacity that has seen costs fall dramatically, we are revisiting the issue. Will Norman asks if the seeds for a looming quality problem have already been sown.
Digitalisation offers PV plant operators the opportunity to shift from preventive to predictive maintenance practices. Eduardo Sarquis reports on research aimed at shedding further light on the system performance benefits of moving to a predictive O&M strategy.
