A panel that under-produces costs money in silence. PV Watcher keeps a continuous eye on every plant — measuring what each one should make against what it actually makes, and flagging the gap the moment it opens.
Monitoring is not a dashboard — it is the discipline of comparing every plant to its own expected behaviour, every hour.
Each plant carries a physical expectation — derived from its capacity, orientation and the irradiance it actually received. PV Watcher compares measured output to that model in real time, so a shortfall shows up as a number, not a hunch.
Dust, shading, a tripped string, a failed inverter — each leaves a distinct signature in the data. Gradual drift points to soiling; a sudden step points to hardware. PV Watcher separates the two so the right crew is sent.
The performance ratio (PR) is the honest score: how much of the available sunlight a plant converts after all losses. Tracking PR over time turns a vague feeling of underperformance into a trend you can act on.
An alert is only useful if it means something. Thresholds are set against each plant's own baseline, so you hear about the meaningful losses — not every passing cloud — and a quiet inbox actually means a healthy fleet.
One plant is a chart; a hundred plants is a portfolio. The fleet view ranks every site by current health, surfaces the worst offenders first, and lets one operator hold an entire estate in a single glance.
Honestly: monitoring is also the foundation for dispatch. The same yield and availability signals that flag a fault also tell the BESS Optimizer how much generation it can actually count on — so storage decisions rest on what the plants are really doing, not on a nameplate.
PV Watcher tells you what each plant is producing and whether it is healthy. PV Radar checks the live status of a site for yourself, and the BESS Optimizer turns those generation signals into charge and discharge set-points on real hardware — vendor-agnostic, within grid and SLA limits.
