Designing and performance evaluation of a solar water pumping system

Abstract

This study includes the detailed designing of solar water pumping system and its performance evaluation. Water pumping system is an ancient procedure and many methods have been established. Human energy, animal power, hydro power, wind, solar and fossil fuels for small generators are all used as power source, above all PV system is chosen because it is durable ecofriendly and long lasting. As Bangladesh is at semitropical region so sunlight is available for that PV system is perfect for generating power for pumping. A good sizing is important for having more efficient system. A flowrate equation related with input power of the PV system has been established based on 1st affinity law, 2nd affinity law, and efficiency law and power equation. With the help of equation, the input power and the Flowrate has been analyzed, based on that analyzation the sizing can be assumed more accurately and increased the efficiency. Thus the performance of the systems has evaluated.
