POLINGA<br/>A micro-hydropower system was evaluated for battery charging at the Villa Colmenar<br/>Resort in Tambo Kulit, Indang, Cavite. The charging power, charging time, charging voltage, and<br/>charging current were determined and analyzed. The efficiency of the system was also<br/>determined. Performance test of the system was conducted at a head of and at different<br/>discharge conditions of the 10.45 ABSTRACT battery. The system was tested at constant head<br/>and four (4) discharge conditions of the battery. The batteries were discharged using or (4) units<br/>12-V, 21 CP, bulbs to reach the different discharged condition of 50%, 75% and 100%. The<br/>batteries were charged individually. Results showed that the system reached an average<br/>charging Power of 46.61 watts, average charging current of 3.21 amperes, average charging<br/>voltage of 14.71 volts, and charging time of 7.63 hours. The system's efficiency with respect to<br/>the theoretical waterpower was on the average of 6.59%. The system was very small to fit the<br/>theoretical waterpower of the head being used. The system amounted to P5, 102.50. vii<br/>automotive 25%.
