Evaluation of Facade Integrated Solar Collector in Oslo

The evaluated solar thermal collector provides half of the energy needed for a household’s domestic hot water. It is a simple low cost energy solution that many regular households can use. The solar thermal system is for sale and government backing is provided in Norway. The experiments were conducted at the Solar Laboratory, University of Oslo in July to October 2012. The system included a 4.2 m2 vertical solar collector and a 0,3 m3 hot water tank and monitoring equipment. The system was designed to meet half of the annual total tap water demand (4800 kWh). The storage tank was emptied each day to simulate domestic hot water consumption. All days in August and September 2012 were included in the analyses. Good correlation was found with the solar radiation, though it was a summer with lower solar radiation than a normal year. In order to evaluate the system for a typical year values from MET Norway were used. The solar collector yield was 366 kWh/m2, year if the solar collector was used March to October. These results mean that a collector area of 6.6 m2 is required to produce 2400 kWh per year. By improving the collector and by using “Solar Glass” and also harvest heat during the winter the collector area could be reduce to 5.4 m2.Validerat; 20140915 (global_studentproject_submitter
