Abstract

The use of electrical energy to supply either clean water or water for agricultural purpose persistently to increase in line with the population growth. The primary objective of this study is to conduct a feasibility study of the utilization of solar energy for driving pumps in Aceh Province, to perform computer simulations for designing solar energy water pump system, and to measure the performance of the small scale solar energy water pump system. The analysis result shows that the potential of solar energy in Aceh Privince can be used to drive the pump for irrigation and clean water for the needs of the community. The performance measurement result shows that the 50 Wp PV panel is capable of driving the pump with 60 Watts of power for 4-5 hours, on a cloudy day, and 8-10 hours on a sunny day.

Abstract

Solar energy is a renewable energy. In Indonesia the potential for renewable energy is very abundant but there is no optimal utilization. The use of solar energy, one of which is to use solar collectors to collect solar thermal energy. Solar water heater is a device that uses solar radiation and converts it into thermal energy. To get the most out of the collector, many ways can be done, one of which is the influence of the distance between the pipe passages, the length of the pipe passage and the diameter of the pipe bends. Then the closer the distance between the passage of the pipe will get the results of greater collector efficiency. In this research, the effect of sharp turns on the pipe with a total length of 4 meters is varied into 4 pipe length variations (70, 30, 20) cm and the shape of the Circle on the heat transfer of the solar water heater. From the research with the sun intensity of 691 W / m2 occurred in collector C (20 cm). The optimal results obtained are an outlet temperature of 64 OC with useful heat energy of 447.69 W / m2 and an efficiency of 89.98%, occurring at 14.00 WIB.
