Can a PV system power a water pump?

Integrating PV systems with water pumping systems offers a dependable and eco-friendly solution for powering irrigation systems. PV systems capture solar energy and convert it into electricity using the photovoltaic effect, and this electricity is subsequently used by water pumps to supply water for irrigation .

How does pumped-hydro storage work?

By integrating with solar systems pumped-hydro storage converts renewable electrical energy (solar) into mechanical energy and vice versa. The solar energy received by pumped hydro system is used to pump water from the lower reservoir to the upper one to be release during peak load hours (Canales et al., 2015).
