The corresponding experiment compares the performance of two identical solar panels, which are subjected to different scenarios. The objective of this research is, to categorize or establish on site solar-radiation ranges in order to estimate the actual solar-panel efficiency compared to 1000 W/m2. The maximum power point is calculated using an I vs V transfer function approximation. The soiling related maximum-power-point impact analysis is carried out with a complete Multivariate Analysis of Variance (ANOVA) considering three fundamental factors: dirt/particles, solar radiation and day. According to experimental results, the soiling effect in the solar-panel efficiency reduction has been estimated as up to 6% during times of the day with the maximum solar radiation; while for lower radiations, the effect decreases exponentially becoming negligible on the available electric power. Thus, empirically it is shown that the effect of dirt/particles is significant from a clean solar-panel to one with light accumulation, but such a negative effect rapidly diminishes as accumulation changes from light to heavy. Therefore, it is suggested that once some dirt accumulates on a panel, a cleaning procedure can wait until the particle accumulation becomes heavy. Thus, this study can become a tool that solar-power-plant operators can employ to estimate the trade-off between photovoltaic-system power efficiency and its financial viability. 2020 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43064359003 https://www.redalyc.org/journal/430/43064359003/ https://www.redalyc.org/journal/430/43064359003/html/ https://www.redalyc.org/journal/430/43064359003/43064359003.epub https://www.redalyc.org/journal/430/43064359003/movil 10.17533/udea.redin.20191156 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.97 |
