Solar energy is certainly one of the most important renewable energies available, and we use it under two forms: thermal and photovoltaic. The Solar Energy Measurement System (SEMS) developed by GEONICA is the most advanced technical solution for the measurement of all the components of Solar Radiation:
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.
Additionally, Solar Spectral Irradiance (SSI), plus AOD, Ozone and Water vapour columns can be obtained.
GEONICA introduces the SEMS-PV/2000/3000 Solar Energy Measurement System, a turnkey integral solution for measuring the sun power, that is, the solar energy resource, as well as for the remote monitoring and efficiency analysis of solar power plants, thermal or photovoltaic, in real-time, via Internet.
Our SEMS-PV/2000/3000 Solar Energy Measurement System is the most advanced technical and cost efficient solution for solar energy resource assessment available in the world market today. SEMS-PV/2000/3000 is also the necessary tool for the measurement of Direct Normal Irradiance (DNI), Global Horizontal Irradiance (GHI) and Diffuse Horizontal Irradiance (DHI) to be used as a precise incoming energy reference during the operation of Concentrating Solar Power Plants (CSP), Concentrated Photovoltaic Solar Power Plants (CPV) and Photovoltaic Solar Power Plants (PV).
Solar resource assessment is the first objective to be covered, in order to determine, during a certain time, the site conditions regarding the available solar energy. So the SEMS-PV/2000/3000 System has been designed for allowing the measurement of all solar radiation parameters, such as: Direct Normal Irradiance (DNI), Global Horizontal Irradiance (GHI) and Diffuse Horizontal Irradiance (DHI), by means of highly sensitive Pyranometers and Pyrheliometers supported by very precise solar trackers.
The SEMS-PV/2000/3000 System has been designed around the Remote Data Acquisition and Transmission Unit, Series METEODATA, working as a data logger and, at the same time, as a very precise Solar Tracker Controller. The marriage of the METEODATA Data Logger and the SunTracker-2000/3000 working together, is a unique and exclusive symbiosis solution, which allows profiting all the functionalities of the optional Automatic Diagnosis and Alarm Software (ADAS-3000 option).
The ADAS-3000 software installed at the data logger, is monitoring in real-time the measured values of the main three solar irradiance parameters (DNI, GHI and DHI), supervising also the results of the local running algorithms that are in charge of the Sun Tracker operation
This automatic diagnosis detects in real time any reason of inconsistence of the solar parameters, due to:
Besides the measurement of the solar radiation, the METEODATA unit allows the connection of other additional meteorological sensors. For instance, a wind sensor and a hail detector will offer valuable information for repositioning solar panels, in order to protect them in case of gusts of wind or severe thunderstorms with hail precipitation.
SEMS-PV/2000/3000 System offers direct connection with SCADAs or remote monitoring for retrieving data or reporting site conditions via GPRS/3G cellular network, radio link, satellite, Ethernet, etc., as well as via INTERNET by means of the WEBTRANS Ubiquitas Internet Platform (Web Posting).
Once the solar plant is in operation, other three fundamental issues are covered by the SEMS-PV/2000/3000 System:
GEONICA offers several solutions for the solar market
High accuracy and reliability for solar direct and diffuse irradiance for solar plants
The perfect marriage between a solar spectral irradiance meter and a solar tracker
Automatic Soiling Monitoring System that determines the soiling index for solar PV plants
Solar Panel Power Monitor with 4-20 mA Output of Reference Solar PV Panels
