A "meteorological data base" specifically designed for photovoltaic power plants. It integrates multi-element data collection, allowing direct data integration with the power plant's SCADA/power prediction system, providing reliable input for ultra-short-term and short-term power generation forecasts, module cleaning decisions, and severe weather warnings. Its modular design allows for the selection of elements as needed, replacing multiple separate data collectors with a single device, saving on cabling, communication, and maintenance.
