Calibration & monitoring Beta

Forecasts calibrated
to your real system.

Upload measured production. pvnode detects each array's true tilt and orientation, its performance and its shading, and uses the result in every forecast and historical series.

HOW IT WORKS

One upload,
three findings.

1

Upload measured production

A CSV with timestamps and power, one per array. A full year gives the sharpest result, a few clear weeks already work.

Performance

Measured yield against the physical expectation. 100 percent is spot on. Less points to soiling, degradation or a faulty string.

Shading

A full-year shading map per array, built from the sun's path. Trees and buildings show up where they cost yield.

WHY IT WORKS

You cannot spot a fault
without a clean reference.

Models trained on system data learn the faults in. Shading, soiling and degradation end up in one blurred correction.

A physical model knows what a fault-free system delivers under the given weather. The difference to your measurement becomes a signal, and the causes stay separate: geometry, performance, shading.
