Table 5: _Cont._* Relative Humidity (%)--Kalamata: In addition to temperature, humidity in Kalamata is also a significant factor, further emphasizing the role of meteorological conditions in this region. * Temperature (\({}^{\circ}\)C)--Argos: Temperature in Argos is another vital feature, indicating that this region's climate heavily influences energy production. * Temperature (\({}^{\circ}\)C)--Florina: The temperature in Florina is crucial, although to a slightly lesser extent than in the previously mentioned areas. It is still a significant predictor in the model. * Temperature (\({}^{\circ}\)C)--Ioannina: Ioannina's temperature also contributes notably to the energy production forecast, reinforcing the importance of temperature as a feature across multiple regions. * Temperature (\({}^{\circ}\)C)--Kavala: Temperature variations in Kavala are another important factor, although with a somewhat lower impact compared with the top-ranking features. * Relative Humidity (%)--Florina: Similar to Kozani, humidity in Florina is a critical element in the model, affecting the energy output predictions. These SHAP values collectively indicate that temperature and humidity are the dominant factors influencing energy production, with wind speed and direction also playing significant roles, particularly in regions like Kozani and Kalamata. Understanding these variables' contributions helps in optimizing renewable energy resource deployment and maximizing efficiency based on the local climate conditions of each region.
