Excel Toolkit, Net Positive Suction Head, Actual PV Array Size, onomical Module Size, Water Pumping SystemAbstract
Due to the fact that the price of fossil fuel is increasing in developing countries, many researchers are investigating the scientific research to overcome the challenges day to day. This research was focused to Design solar water pumping for supplying water for multipurpose utilization in Shambu town. Normally water pumping needs generator driven pumps, which requires fuel and human labor but the diesel generator is operated through the man power by using fuel diesel and also needs maintenance. The design and Evaluation of the system was done by using Ethiopian Excel Toolkit through fitting Locations, The results found by design for Total daily water requirement, Maximum (Design flow rate), Storage thank size, Net positive suction Head (NPSH) available, NPSHrequired, PV array size needed, most Economical module size and Actual size PV Array, recorded values from the toolkit were 4,750.9m3/day,261.7L/s, 9,501.8m3, 14.28m, 5.00m, 8896wp, 150wp and 9000wp respectively, considering design month of July(5.0kwh/m2/day) of solar irradiance. The Design for solar water pumping system contributes basic knowledge for local community by creating awareness and assists them, to use the design sample as starting point to install solar water pumping system and for cultivations of crops via familiarizing themselves with new technologies.
