Water from broundcaptering that will be consumed by the public must meet bacteriological requirements, especially E. coli bacteria and for that, disinfection is needed to eliminate them. The purpose of this research is to develop the potential of solar cells as a source of chlorinator energy for disinfection of clean water so that it is suitable for public consumption according to Permenkes RI No. 492, 2010. This experimental research method was to make a chlorinator from a solar cell energy source for disinfection using chlorine in clean water with performance testing, with variations in distance of 0 km, 0.5 km, 1 km, 1.5 km and 2 km resulted in residual chlorine <0.7 ppm and mpn coli. Components of the chlorinator consist of Solar cell panels; DC Converter stabilizer and Digital current voltmeter; Control solar cell system and battery changer; Battery; adjustable velocity; double membrane pump (chlorine pump) Control switch internet system or an Internet Controller Semiconductor (ICS) that uses a modem; Submersible pumps. The performance of chlorinators in an effort to provide clean water that is suitable for public consumption are: double membrane pump discharge: 50 lt/hr of chlorine at 1-1.5 lt/s source water flow, the results are: residual chlorine at a distance of 0 km, 0.5 km, 1 km, 1.5 km and 2 km respectively: 0.68 ppm 0.53 ppm, 0.45 ppm; 0.41 ppm and 0.29 ppm and free of mpn coli.
