Teknologi Pemanas Air Menggunakan Kolektor Tipe Trapezoidal Berpenutup Dua Lapis

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 resea…
