Abstract

Access to water is a basic requirement for human life. However, currently there are still many small and remote communities that are relatively poor and still do not have access to better water sources. The absence of electricity and high fuel costs induce the need for pumping water to the community. The study designed a water supply system by using solar photovoltaic (PV) to generate power for water pump applications in Hatuermera village, Manatuto district, Timor Leste. The study used two methods, namely the pumping and the gravity system to take into account the geographical conditions and the location of the settlements. The solar water pumping system design needs several data such as information on water sources, water requirements, elevation differences, system components and local climate. The results showed that the water need to supply for 245 residents with a distance of 540 m and a height of 163 m between water sources and residential areas is 8.09 m3/day. The design used a helical rotor submersible pump with DC current using a large total static head and small discharge to increase the efficiency, because electricity from solar panels is DC electricity. The total peak power of the PV array required is 2379.7 Wp which is supplied from 6 solar modules with a power rate of 400 Wp which are connected in series.
