Hi all. I am doing a project where I have to design a photovoltaic water pumping system that can be used for applications like water irrigation and borehole water extraction.Right now I am doing my research and the issues that are the most pertinent are the following:1)hybrid systems,2) making the system completely autonomous i.e providing power for the auxilliaries as well and 3)solar tracking. I have searched for books available on the topic on Google but I have not obtained books that can be viewed fully. Also, I am having difficulties in obtaining materials that pertain to Photovoltaic Pumping exclusively or where the focus is more on PV pumping. Can anybody help me please?
