Experimental tests have been performed on the laboratory stand that contains solar simulator, vacuum collector, fluid circulator, heat exchanger and measuring system. The efficiency of the vacuum solar collector was determined at heat-transfer flow rates of 0,033, 0,041 and 0,044 kg/s. Appropriate mathematical equations were defined corresponding to the proper flow rate. The highest efficiency was 0,83 at a fluid flow rate of 0,044 kg/s.
