Performace evaluation of solar photovoltaic pump for operating of landscape system

Abstract EN

Most landscapes requires the water essentially, water pumping consumes a significant amount energy.

The study carried out to evaluate the per-formance of a solar water pumping system for the purpose of operating landscape system.

The sys-tem consists of a centrifugal water pump connect-ed directly to DC electric motor that which con-nected directly to a solar photovoltaic generator.

Field test had been carried out at Menofia Gover-norate, Egypt.

Measurements were taken every hour starting from 8:00 AM to 4:00 PM through randomly selected days during the period between August 2016 and February 2017.

Results show the relation between the solar radiation and the output electrical power, hydraulic power, pumping rates and the efficiency of the system.

System evalua-tion was carried out by estimating the intensity of solar radiation, Photovoltaic output power and the hydraulic power generated.

The PV output power was 712 W at solar radiation intensity of 841 W/m².

Also, photovoltaic generator and pumping system efficiencies were 14.98% and 14.21% respectively.
