1. A system comprising:
a first photovoltaic string configured to produce a first string power, wherein the first photovoltaic string comprises a first plurality of photovoltaic panels;
a circuit configured to measure the first string power;
a load connected to the first photovoltaic string and configured to receive the first string power from the first photovoltaic string;
a controller connected to the load and configured to:
transmit a first signal to the first photovoltaic string, wherein the first signal comprises an instruction to continue power production by the first photovoltaic string;
measure a total power delivered to the load;
receive the measured first string power;
compare the total power delivered to the load and the measured first string power to produce a power difference; and
cease, based on the power difference being greater than a threshold value, transmission of the first signal to the first photovoltaic string to stop the power production of the first string power.
