Solar Thermal uses heat from the sun to heat water for use within the property. A solar collector panel is installed either onto or set into your roof, or evacuated tubes are placed above the roof.
Sunlight passes through the glazing of the panels and strikes the absorber plate which heats up, changing solar energy into heat energy. The heat is transferred to a glycol fluid (a mixture of anti freeze and water) passing through pipes attached to the absorber plate.
This liquid then travels via a pumping station, which circulates the fluid and checks the pressure and temperature, down to your hot water cylinder and passes through a coil in the cylinder, transferring the heat from the liquid to the water in the cylinder which is then stored until you use it.Solar Thermal Panels are eligible for the Renewable Heat Incentive, this allows you to earn money from the government for using renewable technology.
Where can I place my solar thermal panels?
To maximise the performance from your system it should be placed on a south facing surface with a 45 degree tilt towards the sun in an unshaded location. A south-east or south-west facing roof will still deliver a good yield of energy.
What maintenance does a solar thermal system require?
Minimal maintenance is required to keep the solar thermal system in good operation. However, we would recommend getting the pressure checked at least every 1-2 years just to make sure your system is able to perform at its best. The water/anti-freeze liquid that circulates within the system will need adding to or replacing at five year intervals. Our installers will be able to recommend a suitable maintenance schedule.
Do I have to clean the panels once they are installed?
The panels do not usually require any cleaning as this is done naturally by rain and aided by the 45 degree angle.
Yes, we always recommend an annual service to be carried out on all Solar Thermal systems. If your system is registered for the RHI ( renewable heat incentive) and you are receiving payments, it is a requirement to have the system serviced by a qualified service engineer every year.
