Performance test of manual wind based water pump in coordination with solar panel based pump

The water requirement for watering the garden is an essential factor, therefore maintaining the continued supply is necessary. Pumping water for gardens using Solar panels has been introduced in many applications. However, there is a drawback of using solar panels alone which the optimum time for radiation for Indonesia is around 5 to 6 hours only. Moreover, cloudy conditions could reduce the number of radiation hitting the solar panel. In this paper, the use of Savonius Turbine to pump water mechanically is employed to maximize the supply of water to the garden. The water supply is fed from the Savonius Turbine while when the wind speed is low enough (less than 3 m/s), water supply will be fed from the water reservoir by opening the tap from 50% when the wind speed between 3 to 6 m/s, or 100% when wind speed less than 3 m/s. The tap will be closed when wind speed achieves 6 m/s. This paper aims to investigate the performance of the coordination between the manual pump that is mechanically operated by Savonius Turbine and the level of the opened tap of the water reservoir. The solar panel is operated based on the level of the water reservoir. If the level of water in the reservoir is below 10cm, the DC water pump will operate to fill the reservoir and stop when it’s full. The coordination and data acquisition are done and collected by a microcontroller. From the performance test, it could be concluded that the whole system could work properly based on the implemented design and manufacture.
