Effectiveness of Solar Pump for Irrigated Rice-2014

Dr M A Rashid
CSO and Head
Irrigation and Water Management Division, BRRI, Gazipur-1701, Bangladesh.

Abstract/ Executive Summary:

An experiment was carried out to evaluate solar pump for energy output, pump discharge and irrigated area, and to investigate multiple use and economic performance of solar pump. A solar panel was installed. The panel size was 1.5 m² x 8 = 12 m² and the capacity was 1600 watts. Submersible pump was used and the capacity was 1 kw. Pumping water has been started since September 2014. Surface water is being pumped from a pond at 3 m head. The maximum volume of pumped water during September was 8.2 m³/hr which is equivalent to 137 litre/min. The highest discharge was observed from 12 noon to 2 pm. The average rate of pumping during September was 45.5 m³/day which can irrigate 3.5 bigha (0.5 ha) of land. The highest discharge during this month was observed 64 m³/day.
