Many faults in photovoltaic systems occur slowly and are difficult to detect, such as soiling or shading due to vegetation growth. EKZ and the Swiss Data Science Center have developed algorithms to detect them early and prevent loss of energy production.

What is a digital twin, what can it do, and what requirements does it have to meet to be of practical use in the machine industry? ETH researchers and three companies investigated these questions and came up with some surprising results.
