Applications and required measurement instruments

Depending on the planned solar power plant, we recommend the following measurements:

Small PV power plant     

Medium PV power plant     

  • Recommended measurements: GHI, DHI and calculated DNI
  • System components:
    • Data logger
    • Steel cabinet with solar power supply and communication system
    • Rotating Shadowband Irradiometer to measure GHI, DHI and DNI (calculated)
      Optional:
    • 2 solar reference cells (horizontal and tilted)
    • Delta-T SPN1 Pyranometer to measure GHI, DHI and DNI (calculated)
    • Pyranometer tilted in the same angle as solar module to measure GTI

Large PV and CPV power plant     

CSP power plant     

In order to perform a complete site assessment, we recommend measuring additional components:

  • Ambient temperature
  • Wind speed and wind direction
  • Air humidity
  • Air pressure
  • Precipitation amount and frequency
  • Soiling
