See your plant the way it actually behaves.

The problem

Most O&M teams run on 15-minute SCADA averages and a per-OEM portal that hides the granularity that matters. By the time you can compare a string that's drifting against its neighbours, the soiling event, the diode failure, or the connector burn-out has been bleeding kWh for days. Performance engineers reconstruct what "probably" happened from coarse data.

How SolarTwin solves it

• Live dashboards for DC voltage and current per string, AC power per inverter, module back-of-cell temperature, ambient temperature, POA irradiance, GHI, and inverter efficiency — out of the box.
• Sub-second updates via SignalR. When an inverter publishes, the screen reflects it within a heartbeat. No 15-minute lag, no page refresh.
• OEM-normalised tags so a Huawei tag, a Sungrow tag, and an SMA tag show up on the same dashboard panel with consistent units and ranges.
• String-level comparison — adjacent-string deviation calculated continuously, so the under-producing string in row 14 stands out from a kilometre away.
• Time-series history retained at full resolution — no down-sampling that silently drops the transient you cared about.
• Compare windows — overlay yesterday against the same irradiance conditions last week, or any custom interval.

How it works

1. Your inverter or plant controller publishes telemetry over SunSpec Modbus, IEC 61850-7-420, OPC UA, or MQTT (we bridge any of them).
2. SolarTwin parses, normalises against the inverter model schema, and writes to the time-series store.
3. Every connected client — operator dashboard, mobile, integrated control system — sees the change in under a second.

What you can do with it

• Catch a clipping event as it happens, not in next month's PR report.
• Validate a string-current deviation against the live POA irradiance instead of guessing from 15-minute means.
• Hand new operators a single source of truth on day one — across every plant in the portfolio.
