Abstract
Research on utilization of solar energy for heating water using parabolic collectors
equiped with mirror that used as reflectors have been done. Parabolic collectors were
placed on direct sunlight with 500 grams, 750 grams and 1000 grams mass of water
in the container during 15 days of observation. The observations were carried out at
time interval of 30 minutes from 10.00 am until 15.00 pm. The results of research
showed that for mass of 500 grams, 750 grams and 1000 grams produced the highest
temperature with the values respectively of 91.2 °C, 90.6 °C and 95.4 °C with
radiation intensity 572.8 W/m2, 589.7 W/m2, and 612,3 W/m2. The magnitude of
solar radiation intensity affects the amount of heat received by water, heat received
by container and combined heat of water and container.
