In the GOLD package, the PV plant production and meteo data are acquired automatically in real time by mean of the sensors provided, to be installed at the plan site. Furthermore, the user is provided with additional facilities described below:

  • PR standardization: PR net of temperature losses

PR measure is objective but it is hard to compare, as it changes considerably with temperature variation of the solar panel.

In other words, if the PR is based on data gathered over a 12 month period it can be considered a valid index, but for short periods it is less useful. SunXman also calculates and provides the PR net of temperature losses.

The Net PR has more stable and comparable values, so it becomes the real index of PV plant performance.

The system estimates the module temperature with a high level of accuracy, according to the sunlight, type of mounting of the modules (roof or ground mount), ambient temperature and wind speed.

  • Automatic gathering of production losses and malfunction status, based on the constant comparison between PR net of temperature losses and the established threshold.
  • Automatic alarms and warnings in real time in case of output net of temperature losses below the established threshold.
  • Automatic calculation on the daily and peak PV plant Rating

A stable situation and the most precise solar energy measurements are needed to correctly evaluate the performance and establish an PV plant rating. The system automatically identifies clear-sky conditions (stable clear sky) and calculates the PR net of temperature losses and elaborates the PV plant rating on the basis of this value.

  • Real time Report: data and indexes updated every 15 minutes
  • Whole Report for every day: daily data and indexes
  • Intra-day charts for every day: charts at 15 minute steps
  • Monthly charts: charts of data and indexes on measured every each day
