The experimental and simulation research on system efficiency of photovoltaic pumping system

For evaluating the influence degree of insolation and pumping head-flow rate characteristic to photovoltaic (PV) pumping system, this paper carried out experiments, established mathematical models of system components, and simulated the system efficiency of PV pumping system with MATLAB/Simulink tools, some conclusions about system configuration optimizing were deduced at the end of this paper.
