-A company from the US offers panel-embedded smart electronic chips, which lock the panel digitally in the moment the panel is being stolen. The technique starts working automatically, if the power optimisers receive no activation signal from the inverter. This immobilisation of the panels ensures that no power is produced anymore, which makes a reuse of the panels impossible.
