Solar water pumps are one of the solar technologies that is becoming popular to fulfil the water requirement, particularly in the areas with limited or no access to electricity. However, the voltage of photovoltaic (PV), one of solar technology, drops as the temperature rises. Therefore, efforts are required to lower the temperature in the photovoltaic. This study aimed to observe the effect of cooling PV on direct-coupled water pump, motor and pump connected directly to PV. In this study, the cooling method used is floating method. Two module of PV were used. A photovoltaic module is firmly installed on an artificial pool as a cooling PV and the other without cooling. The results showed that a cooling photovoltaic (PV) produced higher power output transferred to motor and pump and had higher efficiency. In general, the power generated during the period measurement by PV with cooling is greater than that of PV without a cooling method. At 17:00 pm, when the intensity reaches 236 W/m2, the direct-coupled water pump with cooling PV system is able to operate with 9. 9484 W of power input. Meanwhile, under the same intensity, the water pump without cooling PV come into a halt, with 8. 6597 W of the input power.
