Cooling of PV module is important because with the increase in cell temperature, efficiency drops. In crystalline silicon cell, the power temperature coefficient is -0.05% for 1°C rise in temperature. The life span of PV also reduces due to same reason. Hence, various PV cooling techniques are employed viz. water spray, use of heat pipes, PCM and thermoelectric coating. All such systems have inherent limitations and hence, in the present study an innovative water duct cooling is introduced. Due to it, the PV module temperature is reduced from 47.6°C to 34°C at 300 W/m2 and 66.4°C to 38°C at 900 W/m2 for water flow rate of 1 lpm, which gave 4-7.2% rise in electrical efficiency. The highest thermal efficiency and overall system efficiency observed were 76.64% and 79.1% respectively
