This paper presents an experimental investigation on the thermal performance of a 500-liter integrated collector storage system in the shape of a prism with a right angle. A grid of 45 thermocouples was assembled inside the storage tank to monitor the temperature distribution, which was utilized to estimate the mass-weighted average temperature inside the tank and the heat gain. The total stored energy for a day in August was found to be 105.92 MJ/m3 with a temperature increase of 25.2˚C. In November, the total stored energy was 65.86 MJ/m3 with a temperature increase of 15.5˚C while it was 56.92 MJ/m3 for January with a temperature increase of 13.6˚C. A comparison between the present experimental results and published theoretical results for a similar shape showed good agreement.
