Resumen

This research designed and built an automatic and portable cleaning mechanism for photovoltaic panels (PVs). The climate variation defined the amount of accumulated dust; this modified the load efficiency (η) by 11.05% on average, reaching a maximum of 39.6% in the hour of greatest solar spectrum. The highest value obtained of fill factor (FF) was 0.29 with a clean PV compared to 0.25 of a dirty PV, in all measurements the dust decreases the FF. In this study the power (W) loss should not be greater than 2.17 W, which can be because of dirty panels with dust; and the FF greater than 71%. The amount of accumulated dust decreases the FF, for this reason the cleaning mechanism must be programmable, must be portable and adjustable to different PV sizes. Copyright © The Author(s) 2023.
