    Instruments and analyzers for solar radiation measurements in PV applications

    Solar radiation is not only the driving force behind the Earth’s weather phenomena, it also drives photovoltaic energy production. One day of solar energy received by the Earth exceeds the amount of worldwide energy consumption per year. Exploring this merely inexhaustible source of energy - either by direct transformation of radiant energy into electricity or by indirect energy production via wind, waves, etc. - seems to be the obvious way to go. In this context solar radiation measurements are of primary interest for applications like site-specific solar resource assessments, PV performance evaluation, solar resource forecasting, and so on.

    Instruments and analyzers for accurate solar radiation measurements

    Conducting reliable and accurate solar radiation measurements requires some knowledge and attention: think of environmental influences (wind, rain/snow, soling), re-calibration (bi-annually), not to mention data processing, spectral effects, etc. Essentially, accurate broadband solar radiation measurements are obtained using two components: a suitable set of pyranometers, including an optional pyrheliometer (DNI sensor) with sun tracker, and an adequate data logger.

    Instruments and analyzers for solar radiation energy budgets studies

    The Meteorological research community is very ambitious to understand climate changes and global impact on life. With modern advanced measurement equipment, e.g. satellites, remote sensing technologies and sophisticated computer models, multiple meteorological parameters can be analyzed at a large scale at the same time. As the climate system is very complex it is difficult to give accurate predictions of our future climate. We work with climate models, which are based on the consequences of impacts thus far observed. Apart from these impacts additional forcings occur, which make it even harder to give reliable climate predictions. Nevertheless, our present sophisticated climate models enable us to give a characterization of our future climate. For instance, we expect that before the end of this century, the average surface temperature will have increased by 1.4º to 5.8ºC.

    Instruments and analyzers for DHI measurements

    Diffuse irradiance measurements: Diffuse Horizontal Irradiance measurements are performed with a thermopile sensor called Pyranometer mounted on a Sun tracker or shading ring.  When the pyranometer is installed on an automatic sun tracker, the diffuse radiation can be measured in two different ways. Measuring Diffuse irradiance requires an accurate pyranometer with low offset properties. Duirng clear sky conditions the DHI irradiance (W/m2) is less than 20% of the total irradiance. Zero offsets lead to underestimation of the measured irradiance.

    Instruments and analyzers for spectral irradiance portable solutions

    Reflection and transmission measurements on materials, vegetation, water or atmosphere give valuable information about biological, physical and chemical processes. Processes driven by solar radiation, in particular bands of the spectrum through the so called action spectra, can be analysed or quantified with a sensor senitive in the particular spectral band. The MS-720 portable spectroradiometer gives total freedom to be used in different applications and range of the spectrum between 350 - 1050 nm.
