This paper presents development of solar water pumping system in a karsts rural area Tepus District, Gunungkidul. Two important aspects in designing solar water pumping system are analyzing piping system to determine the type of pump used and the power system planning to ensure the system operates properly. Based on the analysis of the piping system, the horizontal distance is about 1,400 เมตร with total head is 218.34 เมตร and the suitable pump used is submersible pump PS1800 HR-05HL with maximum total dynamic head 250 เมตร. Power system is constructed utilizing total of 32 solar panels consists of four branches with 8 solar panels in series configuration for each branch. This power system produces about 3200 Wp to power the two submersible pumps with water flow rate resulted is about 0.4 – 0.9 litres /วินาที
