Applications: 

Vacuum (also "evacuated") tube solar collectors are amongst the most efficient

and most costly types of solar collectors. These collectors are best suited for 

moderate temperature applications where the demand temperature is 50 -95°C 

and/or for very cold climates. Applications of vacuum tube collectors include 

heating of domestic and commercial hot water, buildings, and indoor swimming 

pools. Due to their ability to deliver high temperatures efficiently another 

potential application is for the  cooling of buildings by regenerating 

refrigeration cycles. Vacuum tube solar collectors have a selective absorber 

for collecting sunlight that is in vacuum-sealed tube. Their thermal losses are 

very low even in cold climates.
