1. A method comprising:
receiving, by a central analysis station from a plurality of solar panels via a communication link common to the plurality of solar panels, a plurality of data transmissions at varying time increments, wherein each of the plurality of data transmissions comprises:
a unique identifier of a corresponding solar panel of the plurality of solar panels, and
performance data of the corresponding solar panel of the plurality of solar panels;
detecting, by the central analysis station and based on the performance data, an anomalous performance in one of the plurality of solar panels; and
displaying, on a display and based on the detected anomalous performance, a status of the one of the plurality of solar panels,
wherein the detecting the anomalous performance comprises:
generating, by the central analysis station and based on the performance data, curves of power production;
extrapolating the curves of power production for each solar panel of the plurality of solar panels; and
detecting a power anomaly based on the extrapolated curves.
