SYSTEM CAPACITY AND ENERGY OF WIND AND ELECTRIC PUMP FOR IRRIGATION

KS Diaba, Felix Kutsanedzie

Abstract


Wind energy technology may turn out to be the best alternative to the use of hydroelectric power for pumping water for irrigation in certain parts of Ghana during the dry season. Keta District provides one of the best wind regimes in Ghana. Wind and energy pumps were set up for irrigation on two farm lands in Keta District were observed and data collected for determining the system capacity of average energy of wind and electric pumps used for irrigation of the farms. An average daily wind speed of 5.4m/s is obtained at this coastal part of the country where obstruction is minimal. This can supply a power of 0.195kW to run six (6) wing rotor of 1.6m diameter whose energy demand is 8.947x10-7kWh. Though the initial cost of installing wind pumps is high farmers in these coastal communities could use wind energy for pumping water for irrigation.
