Influence of The Temporal Resolution of The Water Consumption Profile on Photovoltaic Water Pumping Systems Modelling and Sizing

Photovoltaic water pumping could significantly improve water access, particularly in off-grid rural villages of Sub-Saharan Africa. Earlier, we have developed and validated a numerical model of a photovoltaic water pumping system (PVWPS). Such model allows to include the water consumption profile as an input. The current study assesses the influence of the temporal resolution of the water consumption profile on the model accuracy and on PVWPS optimal sizing. This helps to select the adapted temporal resolution for data acquisition, modelling and optimization in order to keep data storage and computational time low without significantly changing the accuracy of the model and the sizing obtained from the optimization. Our study shows that the temporal resolution has a strong impact on modelling and optimal system sizing.
