What are solar thermal panels?
The purpose of solar thermal panels is to provide cheap hot water for your household. The other type of solar panels, solar PV (photovoltaic), is designed to generate cheap electricity for use in your home or business, or to sell to the national electricity grid for cash. Both rely on the sun’s rays to produce the power necessary for their function.
This means that the failure or drop in performance of solar thermal panels may have a greater and more immediate effect on your quality of life than if a solar PV panel developers a fault or gets broken. Solar thermal is between 70%-80% effective at converting solar energy to hear; solar PV on the other hand is only around 15%-22% efficient. It is cheaper to install than solar PV, and takes up less roof space.

What can go wrong with solar thermal panels?
The risks of damage to solar thermal panels are the same as those for solar PV panels, but because a solar thermal system requires plumbing as well as electricity supplies there are more ancillary and moving parts components that are always prone to fault or failure.
On the plus side, you are more likely quickly to notice the warning signs of a malfunction of solar thermal than solar PV panels, and take action to remedy them.
Typical problems include:
- Malfunctioning or noisy pumps
- Re-gassing
- Pressure fluctuations
- Water leaks
- Control centre malfunction
- Anti-freeze not topped-up
- Air locks
- Atmospheric corrosion
- Coil problems




Prevention is better than cure
Better safe than sorry
Since the panels have no moving parts and also appear to be out of harm’s way, you may have left their performance to chance, rather than detailed inspection and review. Our advice to customers is that a solar thermal system needs to be surveyed every year, at which time its power-generation performance is calibrated, and every electrical and plumbing appliance inspected and tested, down to the smallest fuse.
