Solar Energy
The sun radiates an immense amount of energy to the Earth. If it could all be tapped, the amount of solar radiation that reaches the globe every half hour would be enough to meet worldwide energy consumption requirements for an entire year.

Where can they be used?
Although typically used domestically, there are solar thermal systems on the market to cater for any size of building. Ideally they will need to be mounted on a south facing surface, which receives direct sunlight for most of the day.

What are the benefits?
• Reduces CO² emissions on an average domestic system by up to 400kg per year (depending on the fuel being replaced).

• Easy to install and maintain.

• They can be easily integrated with other heating systems to meet the additional hot water requirements during the winter.

• £400 installation grants are available with year on year returns from the renewable heat incentive of up to £200.

Installing Solarthermal systems
• There are a number of installation options available including surface-mounted options for pitch or flat roofs. A-frames, in-roof and complete roof installation, canopy or facade construction. We can advise you on the best solution for your project.

• Solar thermal systems need to be connected to a twin coil cylinder - which is often bigger than a standard hot water cylinder. One coil receives heat from the solar collector on the roof, while the second receives heat from the other main heat source when there is insufficient sunlight.

• CLK offer a full range of hot water cylinders and can advise you on the correct size of cylinder for your project. Space should be allowed for these cylinders when planning your project.

• You will need 2.4m² of South-East to South-West facing roof space.

• DIY jobs are not eligible for grant funding and the best practice is to use a professional installer.

1. Flat Plate Collectors
Turn heat radiated by the sun into hot water. The liquid that circulates through these thermal solar panels is heated by sunlight; this then passes through a coil in the water tank which in turn heats the water stored in the tank.

2. Evacuated Tube Collectors
Use the sun's warmth to heat water. Unlike flat plane collectors, evacuated tube collectors are made up of several cylindrical collectors, which sit in parallel. These panels can collect more solar energy as the cylinders capture the sun from many angles.

Photovoltaic Panels

Save electric energy by converting the sunlight into electricity. By using photovoltaic panels with a battery, inverter and controller you can start using your own generated electricity for domestic units. Learn more about solar photovoltaic panels.
