Solar PV Performance Monitoring Agent

Solar sites can lose output quietly through soiling, inverter faults or failed strings. Each day this agent pulls production and irradiance data and calculates the performance ratio for each inverter and string. It compares units with each other and with the expected model. When one underperforms, it first checks whether the cause is a data problem or seasonal shading at that time of year. If the loss is real, it classifies the likely cause, estimates lost energy and revenue, and drafts a maintenance ticket. The engineer approves every ticket before a crew is sent. Problems the agent could not confirm are rechecked the next day. Edge case: snow cover across all inverters on the same day is noted as weather, not a fault, so no ticket is raised.
