Abstract
Research on “Technology of Solar Energy for Water Heater Using Double Layers Lid of Trapezoidal Collector” have been done. Trapezoidal collector was lied in the rech on of east-west with respect to sun path, so that sunlight directly come into collector. Observations were carried out for 6 hours and date were recorded every 15 minutes for 14 days. The highest intensity for 14 days research was 503.19 W/m2 which was obtained at 13:00 pm and the lowest intensity accurate at 09:00 Am was 312.13 W/m2. The highest temperature of collector was 66.29 ⁰C accurate at 12:00 pm and the lowest temperature was 33.39 ⁰C accurate at 09:00 Am. The highest container temperature that starting to flow the water out was 84,00 ⁰C which accurate at 10:00 Am and water temperature in container was 37,13 ⁰C which occured at 15:00 pm. The amount of hot water produced using trapezoidal collector was 36,87L/day, while heat lost due to conduction process through the bottom was 2,348 J/s which occurred at 12:00 Am anf through other side was 489.08 J/s accurate at 12:00 Am.
