    • A Hybrid Intelligent System to Forecast Solar Energy Production 

      Basurto, Nuño; Arroyo, Ángel; Vega-Vega, Rafael A.; Héctor, Quintián; Calvo-Rolle, José Luis (Elsevier, 2019-08-07)
      [Abstarct]: There is wide acknowledgement that solar energy is a promising and renewable source of electricity. However, complementary sources are sometimes required, due to its limited capacity, in order to satisfy user ...
    • How political decisions affect the economy of a sector: The example of photovoltaic energy in Spain 

      Fernández-González, Raquel; Arce Fariña, Elena; Garza-Gil, Dolores (Elsevier, 2021-05-27)
      [Abstract]: The economic crisis in Spain (2008–2012) led to a massive decrease in the feed-in tariff on photovoltaic solar energy production, which caused stagnation in the growth of this market. The objective of this paper ...
