Comprehensive Meteorological System for photovoltaic solar power plants.

Sistema SEMS-PV

GEONICA presents the SEMS-PV System, a comprehensive, turnkey solution, with high connectivity with SCADA units, for measuring solar Irradiance, the meteorology and other parameters of interest.

The METEODATA datalogger included with the system supports the connection of all the sensors necessary to carry out the following measurements in the plant:

Solar Irradiance

  • Global Horizontal Irradiamce GHI
  • Direct Normal Irradiance DNI
  • Diffuse Horizontal Irradiance DHI
  • Albedo (depending on the type of plant)
  • Spectral Solar Irradiance (Direct or Global)
  • Aerosol Optical Depth AOD
  • Ozone
  • Water Vapour
  • Spectral Correction Factors (SCF)
SEMS-PV System


  • Temperature
  • Relative Humidity
  • Wind Speed and Direction
  • Precipitation
  • Atmospheric Pressure, etc.

For Panels

  • Soiling (Soiling index of solar panels)
  • IsC (Short circuit current)
  • VoC (Open circuit voltage) of any PV module in the plant


  • Color camera for capturing still images of some point or area of interest of the plant
