The use of photovoltaic (PV) array for pumping water is one of the most promising techniques in solar energy applications. In this paper design and performance analyze of solar water pumping system is presented for college of Agricultural engineers UAS campus conditions. The solar pumping system consists of 32 modules of 255.8 watts each and 7.5 hp DC centrifugal mono block pump. The system was tested for its performance in terms of variation is in discharge due to change in solar testing. It was observed during normal climatic conditions the PV array produced power in the range of 7051.40 watts to 7848.22 watts from 10:30 am to 4:30 pm in the month of December 2014.It was observed that reduction in power generation in the range of 10.16 % during noon conditions. PV array produced maximum power of 7848.22 watts (12:30 pm) while, Vmp and Imp of 490.82 volts and 15.99 amps respective. We have observed in the morning conditions that pump delivered discharge of 33.40 m3/h (10.30 am -11:30 am) of the head of 22.8 m. It was observed that, in noon conditions pump delivered discharge of 41.82 m3/h (12:30 pm) at the head of 22.8m and the pumping efficiency was measured of 66.06 %. It was observed that, power output from the solar array increases as solar intensity increases. So increase in the power output was in the range from 7051.40 to 7848.22 watts.
