Monitoring Time-Series

Solar Energy - main image

Solar power plants perform quite reliably. However during the lifetime of a power plant, especially during the first year of operation, deficiencies in modules and components may result in degradation of performance of a power plant. The true performance of a solar power plant can only be understood by implementation of an active monitoring system. High frequency (hourly) time series of solar irradiance data is a must at this stage. For best results, data from the most recent period, with minimum bias, and low RMSD should be used.

We can deliver hourly averages, daily sums, or monthly sums of solar irradiation and meteorological parameters. For monitoring of PV power plants, we can also deliver simulated PV output data, calculated using real-time solar and meteorological data.

Monitoring Time Series can be purchased for a period of last 12 months or for future 12 months. In case of purchase of time series data for future 12 months, data can be delivered on a regular basis via ftp, web services, or email with a delay of 1 day e.g. data for today can be delivered tomorrow morning.

Advantages of SolarGIS monitoring time series

  • Low RMSD – A key accuracy parameter for solar radiation in monitoring and audits is the Root Mean Square Deviation (RMSD). Compared to traditional satellite-based databases and moderate quality ground sensors, the RMSD of SolarGIS data is lower.
  • High reliability – SolarGIS data has high accuracy and calibration stability. Data availability is guaranteed for 99.5% of the ordered time-series.
  • SolarGIS data eliminates the need of ground sensors for monitoring of small and medium sized PV power plants. In case of large solar energy installations, which use high quality, well maintained, and regularly calibrated pyranometers, SolarGIS data is a vital complementary element to the ground-based monitoring infrastructure.
