The choice of using PV to power a pumping station installation of a public and wider public sector entity in the Greece-Albania Cross-Border Area is based on the following reasons:

• Energy produced using photovoltaics and water consumption could be balanced more easily than using other RES.
• PV systems use fewer technological processes to transform solar energy into electricity.
• PV systems can be located next to or within the premises of the public body and the wider public sector.
• PV power can be hybridized with other non-renewable energy sources by connecting the installation to the grid or to a diesel generator to ensure energy sufficiency under all conditions.

The aim of the design is to determine the required power of the PV, Pel, PV (W) energy production system. Critical data required for this design are the volume of the reservoirs of the water management facility Vop (m3) and total power PPS (W) of the main pumping station (MPS). Each body of the public and wider public sector (with GOEB-TOEB) will be able to use the PV system that works together with the reservoirs in order to provide a continuous supply of water.
