Vacuum tube solar collectors have a selective absorber for collecting sunlight that is in a vacuum-sealed tube, so the thermal losses are very low even in 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.
Our solar collector has been manufactured to the very highest standards, and will provide you with many years of service with minimum maintenance required.

Solar thermal panels with vacuum tubes for water heating
According to Hydro-Quebec average residential water heating costs accounts for 30% of the total electricity cost and heating costs account for 55% of the total electricity costs.
The vacuum tube system that we offer can supply 85% or more of the energy required for the production of domestic water heating. Combined with a heating system the energy costs can be reduced by 50%. It is also possible to connect the system to a pool or a spa, being a modular system it can be increased according to your needs.
A solar water heating system with vacuum tubes can reduce your electricity bill by half or more. The bigger the energy demand the quicker the system pays for itself.
The principles of an evacuated-tube collector
Evacuated-tube collectors can achieve extremely high temperatures (170°F to 350°F), making them more appropriate for cooling applications and commercial and industrial application.

The collectors are usually made of parallel rows of transparent glass tubes.
Each tube contains a glass outer tube and metal absorber tube attached to a fin.
The fin is covered with a coating that absorbs solar energy well, but which inhibits radiative heat loss.
Air is removed, or evacuated, from the space between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss.
