Modeling of the quantity of water pumped by a photovoltaic solar system

This paper deals article is interested in modeling of the quantity of water pumped by a photovoltaic solar system (in direct link with the sun) in transient state. Our calculation program has allowed us to determine the instantaneous flow, on one hand, and on the other hand, to optimize the panel slope which is fixed, according to the latitude over the different regions of Tunisia. For each latitude (varying between 30deg to 48deg), we varied the slope from 25deg to 65deg while maintaining all the other parameters fixed. Thus, we ended to a simple equation which allows us to calculate an optimal slope for each site. Once we have determined the optimal slope, we could determine the hourly, daily, monthly and seasonal variation of the quantity of pumped water by such a system.
