expresses the flow output of the solar pumping system as a function of the dynamic variation of the photovoltaic array power output, for a given pump and pipe parameters. The PVWPS components namely, the pump; solar photovoltaic array; pipeline system and the water storage are sized in an integrated fashion.

Determining Electrical Load for Stand-Alone PV System Sizing

This means the PV system must be sized large enough to handle whatever the electrical load is. Image used courtesy of Pexels . In certain applications, a PV system designer could use only direct current loads, so an inverter would not be needed. Because inverters are not 100% efficient, this helps minimize a stand-alone PV system''s overall size
