What type of Solar Thermal Panels do we install?
These devices look very much like solar PV panels.
They are composed of a dark absorbing surface, a transparent cover, a heat insulating backing and, most importantly, a fluid that transports heat from the absorber to a water tank. The absorber can be made of different materials, namely polymers, copper, aluminium or steel. Copper is the most expensive, but it’s also a better, more durable conductor.
Just like solar PV, solar thermal panels work best if your roof is south-facing, but will still be effective on south-west and south-east facing roofs.
Depending on your home, you can choose to install them on the ground instead of the roof if it isn’t suitable, as long as they get direct, unshaded sunlight.
Solar thermal panels absorb free energy from the sun and transports this energy by way of a thermal pump station directly to the solar coil of your hot water cylinder. Property owners can reduce their utility bills by utilising the heat generated during daylight hours which will result in purchasing less from utility providers year on year.
