• Analysis of polyamide and fluoropolymer backsheets: Degradation and insulation failure in field-aged photovoltaic modules 

      Pascual Miqueleiz, Julio María Upna Orcid; García Solano, Miguel Upna Orcid; Marcos Álvarez, Javier Upna Orcid; Marroyo Palomo, Luis Upna Orcid (John Wiley & Sons, 2022)   Artículo / Artikulua  OpenAccess
      Durability of photovoltaic (PV) modules is of great concern not only from the point of view of cost-effectiveness but also from the point of view of safety and sustainability. The backsheet of a PV module is one of the ...
    • Control strategies to smooth short-term power fluctuations in large photovoltaic plants using battery storage systems 

      Marcos Álvarez, Javier Upna Orcid; Parra Laita, Íñigo de la Upna Orcid; García Solano, Miguel Upna Orcid; Marroyo Palomo, Luis Upna Orcid (MDPI, 2014)   Artículo / Artikulua  OpenAccess
      The variations in irradiance produced by changes in cloud cover can cause rapid fluctuations in the power generated by large photovoltaic (PV) plants. As the PV power share in the grid increases, such fluctuations may ...
    • Early development of the root-knot nematode Meloidogyne incognita 

      Calderón Urrea, Alejandro; Vanholme, Bartel; Vangestel, Sandra; Kane, Saben M.; Bahaji, Abdellatif Upna Orcid; Pha, Khavong; García Solano, Miguel Upna Orcid; Snider, Alyssa; Gheysen, Godelieve (BioMed Central, 2016)   Artículo / Artikulua  OpenAccess
      Background: Detailed descriptions of the early development of parasitic nematodes are seldom available. The embryonic development of the plant-parasitic nematode Meloidogyne incognita was studied, focusing on the early ...
    • In-field energy performance of solar PV module made of UMG silicon 

      Guerra, Moisés R.; Parra Laita, Íñigo de la Upna Orcid; García Solano, Miguel Upna Orcid; Pascual Miqueleiz, Julio María Upna Orcid (IEEE, 2022)   Artículo / Artikulua  OpenAccess
      Upgraded metallurgical grade silicon (UMG-Si) PV modules have failed to make their space in the PV market, which was partly to the uncertainty on their in-field performance that brings the wide disparity of results published ...
    • Long-term degradation rate of crystalline silicon PV modules at commercial PV plants: an 82-MWp assessment over 10 years 

      Pascual Miqueleiz, Julio María Upna Orcid; Martínez Moreno, Francisco; García Solano, Miguel Upna Orcid; Marcos Álvarez, Javier Upna Orcid; Marroyo Palomo, Luis Upna Orcid; Lorenzo Pigueiras, Eduardo (Wiley, 2021)   Artículo / Artikulua  OpenAccess
      Due to high competitiveness in the PV sector, despite the low degradation rate of crystalline silicon PV modules (below 0.5%/year), it is still important for utilities to know its actual value due to its impact on energy ...
    • The potential of forecasting in reducing the LCOE in PV plants under ramp-rate restrictions 

      Cirés Buey, Eulalia; Marcos Álvarez, Javier Upna Orcid; Parra Laita, Íñigo de la Upna Orcid; García Solano, Miguel Upna Orcid; Marroyo Palomo, Luis Upna Orcid (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      An increasing number of grid codes are requiring the limitation of the PV output power fluctuation over a given time scale. Batteries represent the most obvious solution to smooth power fluctuations, with the corresponding ...
