Abstract

The availability of solar energy has great potential for application in the agricultural sector. Electrical power from photovoltaic cells or solar panels mainly depends on sunlight at certain times. The use of this technology can be applied to pump drives in agricultural irrigation systems. In this research, we try to measure a certain time with the efficiency of components from using solar photovoltaic (SPV) with the water discharge produced by the pump on these components. From the experimental results, it was found that the best efficiency was at 14.00 WITA with an efficiency of 57% with the panel facing directly to the sun. From pump testing, it was found that the average water flow was 20.95 liters/minute. From these performance tests, Indonesia itself has sufficient levels of solar radiation to use solar panels as an alternative to sustainable resource.

Abstract

Pelton turbine is an energy conversion medium that utilizes flow performance as a driver and produces electrical energy due to the conversion of turbine rotation. The turbine works when the turbine nozzle injects flow towards the tip of the nozzle which leads directly to the inlet surface of the turbine blade. In this research, we know the effect of nozzle diameter on the performance of turbines that produce different electrical power from various parameters, namely: nozzle diameter used; 1", ¾", 1 ½", and ½" with various nozzle opening variations of 20%, 50%, and 100%. The results obtained with a nozzle diameter of ¾" obtained maximum results with a rotation of 177 (rpm), with a power of 5,168 watts and efficiency increased to 5% at each nozzle valve opening. From these results it can be said that the magnitude or size of the nozzle influences the performance of the turbine where the efficiency of the performance is directly proportional to the rotation and power produced.
