1. A method for arc detection in a system including a photovoltaic panel and a load connectible to the photovoltaic panel with a DC power line, the method for arc detection comprising:

  • measuring power delivered to said load thereby producing a first measurement result of said power delivered to said load;

    measuring power produced by said photovoltaic panel thereby producing a second measurement result of power produced by said photovoltaic panel;

    comparing said first measurement result with said second measurement result thereby producing a differential power measurement result;

    upon said differential power measurement result being more than a threshold value then setting an alarm condition.
