Since installing six solar panels, 785Kwh of energy have been generated, saving 450Kg of carbon emissions.

The solar panels are linked to a display panel in the school foyer showing how much electricity is generated and how much CO2 is saved. As the school hall also acts as the village hall, the display is seen by a wide range of people, generating wide interest. The school children and local community have become more aware of the potential and value of renewable energy.

Rogiet Primary School,
Monmouthshire County Borough Council

24m2 of high efficiency evacuated vacuum tube collectors have been installed in two banks of six panels 2m2 each.

South facing panels are mounted towards the rear of the flat roof section of the main hall. In this position the panels have an unobstructed view of the sky but are not easily visible from the ground, which minimises the visual impact and also reduces temptation for vandalism. Evacuated tube solar thermal panels are prone to damage as the main collectors are glass and are easily broken. These panels will provide sufficient hot water for the majority of the school's needs. The output from the solar thermal collectors is measured and the data is displayed on a special panel situated in the library.

The wind turbine and the solar thermal panels provide approximately 18% of the energy required by the school.

Rhydyfelin Childrens Centre,
Rhondda Cynon Taff County Borough Council

10m2 of vacuum tube collectors have been installed serving twin coil hot water cylinder.  This system is linked to ground source heat pumps and PV panels which, combined, provide the hot water and most of the heating for the centre.

Energy provided by the evacuated tubes is 3000kWh. This is approximately 6% of the energy supplied by renewable sources at the site.
