Where calculated results appear
The same measure can appear on several screens, each answering a different question. When two numbers seem to disagree, they usually differ in plant scope, period, display grain, unit, or how far processing has got. Use this page to find which view owns a number and how to compare it fairly.
Monitor plants
Section titled “Monitor plants”Live status and day-to-day operations.
| View | Grain | Main measures | Guide |
|---|---|---|---|
| Operation Overview | Live status. Day charts show 30-minute points; Month shows one result per day. | PR and PR Corrected (%), Actual Yield/Budget (%), Availability (%), Specific Yield (kWh/kWp), generation (kWh, MWh) | Portfolio and Operation Overview |
| Plant Monitoring | Live and historical. Day power at the chosen resolution; Month and Year as daily or monthly totals. | Active power (kW), daily energy (kWh), irradiance (W/m²), daily irradiation (Wh/m²), grid power (kW) | Plant Monitoring |
Month and Year charts may draw grid export below the axis to show direction; the export amount itself is positive. Interpret load and grid flow explains how to read it.
Explain performance and losses
Section titled “Explain performance and losses”Processed results, used to explain shortfalls.
| View | Grain | Main measures | Guide |
|---|---|---|---|
| Insights → Overview | Month or Year, broken down by month or quarter | Irradiation, Overspill (curtailment), Unavailability, and Soiling losses (kWh, %); actual and budget yield (kWh) | Availability and loss analysis |
| Alarm Analytics | One row per alarm or group; loss estimated from five-minute intervals | Energy loss (kWh), duration, frequency, remarks | Alarm Analytics |
| String Analytics | The current position or a stored past day | Performance score, string current, capacity (kWp), azimuth, tilt | String Analytics |
| Cleaning Analytics | Weekly soiling loss, with weekly, seven-week, and month-to-date cards | Soiling loss and rate, cleaning status, suggested cleaning date | Cleaning Analytics |
A few readings that trip people up:
- Insights: loss percentages depend on the denominator you choose, Budget Yield or Potential Generation. Variance and Meter to Inverter are reconciliation steps, not physical losses.
- Alarm Analytics: an energy loss of
0can mean “not estimated”. Always read it with Remarks. - String Analytics: the score ranks strings within one plant, analysis type, and day. A blank or very low value is something to investigate, not proof of a fault.
Report and export
Section titled “Report and export”| View | Grain | What you get | Guide |
|---|---|---|---|
| Reports | Daily or monthly standard reports; customized views by minute, day, month, or year | Excel reports and saved table views | Reports |
| DataHub | Daily aggregates or five-minute intervals, up to 31 days | Excel workbook of plant, weather station, inverter, meter, string, and subplant data | Export Data with DataHub |
| API | Set by each request | JSON for integrations and dashboards | API overview |
A report reflects the data available when it was prepared. If data for that period is corrected afterwards, open or generate the report again once processing has caught up.
Live and processed results
Section titled “Live and processed results”- Live views, Operation Overview and Plant Monitoring, show current telemetry, device status, and intraday estimates.
- Processed views, Insights, Alarm Analytics, String Analytics, and Cleaning Analytics, show results calculated after data has been processed. Operation Overview’s Month and Performance views also show processed daily results.
The display grain isn’t always the calculation grain. For example, the Day performance chart shows 30-minute points, while losses are calculated from five-minute intervals.
How SolarSENS processes plant data describes the processing stages, and Data freshness and corrections explains how to tell when a value was measured, calculated, and displayed.
Compare numbers across views
Section titled “Compare numbers across views”- Same plants. Both views cover the same plants, inverters, or meters.
- Same days. Use plant-local calendar days, midnight to midnight in the plant’s time zone, not UTC or your browser’s time. Exports can differ: DataHub uses Malaysia time (UTC+8), so check the time zone of any export.
- Same grain. Don’t compare 30-minute points with hourly, daily, or monthly values.
- Same measuring point. Check whether the energy is inverter yield or metered yield.
- Processing finished. Check whether the day’s processing has completed, or whether you’re looking at an intraday estimate.
- Measured, not loaded. The time a page loaded is not the time the reading was taken.
