The activity carried out during the first year and a half of the three-year research period 2022\u00f72024 consists of the management, maintenance, validation and also interpretation of the meteorological measurements acquired at the RSE station in Milan, Italy, operated by the Climate and Meteorology group. In particular, weather data are acquired, such as temperature, relative humidity, ground pressure, wind intensity and direction, and a number of specific measurements related to the integrated irradiance on the solar spectrum (global, direct normal and diffuse irradiance), the direct normal irradiance spectra provided by a spectroradiometer, and now also measurements provided by a celiometer, with which it is possible to obtain precise information in space and time of aerosol and cloud characteristics.<\/p>\n
<\/p>\n
The validation activity has become operational downstream of the acquisition of the measurement files, which are produced once a minute, allowing rapid action to be taken for any instrument malfunctions. In particular, as far as concerns irradiance measurements, the validation process is the one developed by RSE and other international experts in the framework of the task-16 \u201cSolar Resource for High Penetration and Large Scale Applications\u201d of the International Energy Agency – Photovoltaic Power Systems Program (IEA-PVPS).<\/p>\n
<\/p>\n
Finally, the collection of measurements from the spectroradiometer installed at the RSE offices in Milan and Piacenza, at the laboratories of Sardegna Ricerche in Cagliari and at the Enel Green Power innovation hub in Catania continued. This activity, in addition to allowing the populating of a continuous dataset of spectral irradiance measurements, also allows the updating of the machine learning system used in the ARTEMIS (Automatic Radiative TransfEr Model for Irradiance with Satellite data [1]) methodology aimed at estimating the spectral components of direct and diffuse irradiance, implemented within the RdS 2.5 project. Indeed, this methodology requires accurate estimates of aerosols, which can be deduced from the analysis of data collected by spectroradiometer. A key contribution to the development of the methodology will also come from data collected by the celiometer, which can provide additional information for particle characterization and vertical cloud profiling. The effort to continuously feed and validate environmental measurements, especially for characterising radiation, is intended to make up for the lack of observational data, useful both for characterising the Italian territory and for validating methods for indirectly estimating solar radiation.<\/p>\n
<\/p>\n
The results obtained in this LA and the use of the methodology developed in project 2.5 provide a necessary basis for planning the siting of new photovoltaic plant technologies (Si cells type IBC and HJT, tandem cells, bifacial modules, single-axis tracking systems, …) and their management during operation.<\/p>\n
