The vacuum solar collector increases the efficiency of the water heating system. The set of borosilicate glass tubes, inside which there is a vacuum, is highly resistant and has excellent heat absorption capacity, which makes the water heating process much faster. The vacuum in the vacuum tube solar collector prevents the system from being interfered with by the external environment, such as wind, rain, hail, cloudy days, and causes heat losses to be greatly reduced.
The vacuum solar collectors can be used both in industries and larger projects, such as hotels, hospitals and inns, as well as in homes. The vacuum tube system can be combined to obtain a volume capacity of up to 10,000 liters of hot water. It can be installed both on the sloping roof and on flat slab.
