Claim 10:
11. A power generation system comprising:
an inverter coupled between a power grid and a PV array, wherein the PV array comprises a plurality of strings of PV modules coupled in parallel, and a first subset of the strings of PV modules are online and a second subset of the strings of PV modules are offline;
a photovoltaic (PV) array switchably coupled to the inverter;

a set of current sensors that each measure current provided from a corresponding set of strings of PV modules of the plurality of strings of PV modules of the PV array; and
a controller that:
provides a first command to the inverter to apply an initial backfeed voltage on the PV modules;
monitors current data from the set of current sensors; and
provides a second command to the inverter to increase the backfeed voltage such that the current data from at least one current sensor indicates that current flowing from the power grid to the corresponding set of strings of PV modules is below a safety threshold, wherein a current flowing to each corresponding set of PV modules is about equal to a current flowing to each of the first subset of strings of PV modules that are online, such that a surface temperature of each PV module in the first subset of strings of PV modules is increased.
