Solar energy
The Solar Energy Measurement System SEMS is the most advanced technical solution for the measurement of all the components of Solar Radiation: Direct Normal Irradiance (DNI), Global Horizontal Irradiance (GHI), Diffuse Horizontal Irradiance (DHI), Global Normal Irradiance (GNI) and Solar Spectral Irradiance (SSI), plus AOD, Ozone and Water vapour columns.

SEMS-PV is the specific solution for PV plants and SEMS-2000/3000 for CSP plants and when DNI or diffuse measurement (DHI) is required.
For solar energy resource assessment purposes and solar power plant monitoring, generally it is required to measure all the three components of the Solar Irradiance: DNI, GHI, DHI plus optionally GNI. This is made by the Remote Solar-Meteo Stations of the SEMS System, consisting of one METEODATA Data Logger, a Sun Tracker with Shadow Arm/Disc, plus one or two Pyrheliometers and one or two Pyranometers.

For the measurement of the Solar Spectral Irradiance (SSI) it is required to use a Solar Spectral Sensor as the Solar Spectral Meter Model GEO-SSIM, which is the most advanced, unique, efficient and affordable technical solution to measure solar spectral irradiance and DNI in near real-time, when mounted on our SunTracker-2000 or 3000 Series, as part of SEMS System.

Additional meteorological sensors for the measurement of ambient temperature, relative humidity, wind speed and direction, atmospheric pressure, precipitation, etc., can be also connected to the same data logger of the SEMS System. The values of all these meteorological parameters are stored at the data logger and transmitted to a Central Receiving Station or SCADA via 3G/GPRS, Radio-Link, Fiber Optic or through Satellite networks.
The GEONICA SUITE Software Package manages all the communications, data transmission, and remote programming, creating a database with all the information for subsequent data analysis. The information can be also WEB Posted by our WEBTRANS Ubiquitas Internet Platform.

For all the solar technologies GEONICA offers advanced remote Automatic Meteorological Stations for the measurement of the solar irradiance as well as the rest of meteorological parameters of interest.
Solar Irradiance monitoring at PV solar power plants is also carried out by means of solar radiation sensors plus additional meteorological sensors connected to our data logger Model METEODATA Series. Data is stored and transmitted to a local SCADA or to a distant Data Receiving Center (GEO-DRC), in which our GEONICA SUITE software package is installed for system management, remote programming and database generation.
