The available publications up-to-date showed that only one experimental effort has been put on the SSUPP.
Kalash et al. [18] erected a pilot SSUPP in Damascus University, Syria. The prototype has a triangular shape and is tilted at 35o towards the south with an approximate area of 12.5 m2. The chimney diameter is 0.31 m and it is 9 m tall. Eighteen temperature sensors were installed inside the sloped solar collector to measure glass, air, and absorption layer temperatures in different points along the collector. Experimental data were recorded every 10 min for a total of 40 consecutive days during winter from 27/01/2012 to 06/03/2012 to investigate the temperature
changes in the sloped collector. Fig.4 shows the SSUPP prototype after erection.
