What are the main advantages of evacuated tubes vs. flat plate collectors?

  1. Increased Efficiency: due to the tubular shape of the evacuated tubes, the sun is always perpendicular to the surface of the glass for most of the day, unlike the flat plate which reaches maximum efficiency only at noon time.
  2. Minimum Heat Loss: since air is evacuated from the glass tubes to form a vacuum, it reduces the heat loss from the tube. This means that wind and cold temperatures have less effect on the collector’s efficiency.
  3. Freeze Protection: evacuated tube collectors can be used in freezing conditions without the system being damaged, unlike the flat plates which require more sophisticated antifreeze systems which increase maintenance costs and lower efficiency.

 

Application

Residential Solar Water Heating

Most of the produced and sold solar collectors are used for supplying residential hot water using compact thermo siphon systems.

 

Commercial Solar Systems

Commercial solar systems are installed for heating or preheating water in hospitals, hotels and businesses using compact thermo siphon systems.

 

Swimming Pool Heating

The solar system is linked to the hydraulic circuit used for filtration, and this makes the installation very easy.

 

Heating

Solar heating systems can be used to support various kinds of heating systems.

 

Industrial Solar Heating 

Due to high temperature provided only by evacuated tubes, a split system can be used for many industrial applications.
