What are the main advantages of evacuated tube over flat plates collectors?
- Increased efficiency: due to the tabular 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.
- 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.
- 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
