Solar PVMonitoring

Solar PV, watched down to the string.

Utility-scale fields, C&I rooftops and hybrid sites in one view. Alpha AI learns how every string and inverter should perform, and tells you the moment one doesn't — with the reason why.

String-level

Every string compared with its neighbours.

A failed fuse, a shaded block or a broken connector hides inside inverter totals. Alpha compares each string with its siblings at equal irradiance, so small losses surface in hours instead of at the annual inspection.

Alpha AI on PV

Soiling, clipping, curtailment or a real fault — it knows the difference.

Lost energy is split by cause, so you clean when it pays, argue curtailment with evidence, and send crews only for faults.

Blown string fuse on S-12, not shading.

Replace the fuse at the next visit. Current loss is about 0.4 MWh per day.

What Alpha watches on every PV site

Strings

Current and voltage per string, compared with siblings at equal irradiance.

Inverters

Efficiency, temperature, fault codes and trips, correlated with grid data.

Trackers

Angle against the expected sun position, and stow events.

Soiling

Loss estimated per block, with the day cleaning pays back.

Clipping & curtailment

Energy lost to inverter limits and grid orders, kept apart from faults.

Degradation

Year-on-year performance per block, against the module warranty.

Weather

Satellite and on-site irradiance, temperature and snow cover.

Grid

Voltage, frequency and export limits at the point of connection.
