Resumen
[ES] En los próximos años elsistema eléctrico español va a tener una elevada contribución de la energía
solar PV. Estudiarsu variabilidad esfundamental de cara a que elsistema sea fiable. En este trabajo
se analiza la variabilidad de la generación PV en España, incluyendo sus causas, a lo largo del
periodo 2007‐2021. El análisis se lleva a cabo en escalas mensual, estacional e interanual, usando
datos horarios reales de factor de ocupación. Para ello, en la primera parte del trabajo se llevó a
cabo un proceso de corrección del efecto de deterioro de lasinstalaciones PV a lo largo del tiempo.
Los resultados muestran una acusada variabilidad mensual y estacional, causada por el ciclo solar
y asociada a la viabilidad de la radiación solar. Adicionalmente, se encontró una muy acusada
variabilidad interanual de la generación, con cambios de más de un 10%, asociada al ciclo de la
NAO.
[EN] In the coming years, the Spanish electrical system will have a high contribution of PV solar energy. Studying its variability is essential in order for the system to be reliable. This work analyzes the variability of PV generation in Spain, including its causes, throughout the period 2007‐2021. The analysis is carried out on monthly, seasonal and inter‐annual scales, using actual hourly capacity factor data. To this end, in the first part of the work, the so called “aging” effect of the PV plants was corrected. The results show a marked monthly and seasonal variability, caused by the solar cycle and associated with the viability of solar radiation. Additionally, a marked interannual variability of generation wasfound, with changes of more than 10% associated with the NAO cycle.
