Sistem Pemanfaatan Energi Surya Untuk Pemanas Air Dengan Menggunakan Kolektor Palungan
A research has been conducted on Solar Energy Utilization System for Water Heater using Trough Collector. This research was carried out using an experimental method by putting in place an opened trough collector that exposed to sunlight. The experimental results showed that the highest temperature of collector produced was 50,03°C in average with an average temperature of water in the tank was 40,07°C at 1 PM, while the lowest temperature of collector was 39,14°C in average with an average temperature of water in the tank was 35,28°C at 10 AM. The highest temperature of collector occured at 1 PM, because the intensity of solar radiation at the time reached the maximum value. The experimental results showed that the higher the intensity of solar radiation, the higher the temperature of the water produced. The temperature of collector was also influenced loss heat by conduction of the collector. The highest loss heat by conduction was 29,05 J/s at 1 PM, while the lowest loss heat by conduction was 16,85 J/s at 10 AM. The volume of water produced an average was 38 liters in a day during 6 hours from 9 AM to 3 PM.
