Monitoring of distributed power harvesting systems using DC power sources

An apparatus comprising:

• a computer comprising software that, when executed, causes the computer to:
• receive, from a control circuit of at least one solar panel, data that was collected from the at least one solar panel, wherein the data comprises at least one of a location, a temperature, a spatial orientation, or a lighting condition associated with the at least one solar panel;
• determine, based on the data, an expected power of the at least one solar panel;
• receive, from the control circuit, a measured power of the at least one solar panel;
• detect, based on a comparison between the measured power and the expected power, a fault in the at least one solar panel, and
• output, to a display and based on the detected fault, a status of the at least one solar panel.
