The performance of the box-type solar collector was investigated experimentally, the cover of which is a high-vacuum plane glass plate with a middle narrow slot. The acquired experimental results were compared with those for box-type solar collectors using conventional double glazing. From the investigations in this work, it was concluded that the performance of the box-type solar collector can be improved significantly using plane vacuum glazing as the collector cover.
