Experimental research were performed on vacuum solar collector and heat exchange reservoir stand accordance to IS09806 standard. Efficiencywere determined by changing mas flow rate ofheat transfer fluid. It is estimated that average efficiency is highest 0,75 when flow rate of heat transfer fluid were lowest 0,005 kg/s. As well as average efficiency is lowest 0,42 when flow rate ofheat transfer fluid were highest 0,12 kg/sVytauto Didžiojo universitetasŽemės ūkio akademij
