Solar powered homes are a step closer to becoming a reality...

Two four bedroom townhouse properties are being fitted with solar thermal panels and solar photovoltaic tiles that use the sun’s heat to provide hot water and electricity to the home.
The homes will be sold with the solar technology at no additional cost to the homeowner and Countryside Properties will assess the energy bill costs for the property over a 12 month period. The results will be used to fully understand the impact the technology has on a home’s energy efficiency with a view to rolling it out across other Countryside Properties developments.
Reducing the environmental impact
Peter Redgwell, Countryside Properties’ Technical Director explained: Government legislation now demands that house builders reduce the environmental impact of new developments by building homes that generate clean renewable energy at the point of use.

On one property, two solar thermal panels covering a surface area of 5 square metres will be integrated into the rear roof slope facing South East, in order to maximise exposure to the sun. These panels contain a liquid which absorbs the sun’s heat. Connected to the property’s hot water cylinder, this is used to warm up the water inside. A controller then measures the temperature of the water and if it isn’t hot enough the boiler will fire as necessary.
Saving energy costs
The second property will be fitted with 12 solar photovoltaic tiles covering 8 square metres across the rear roof slope again facing South East. Semi-conductor materials within the tiles generate an electric current when exposed to light and this is converted to electricity for use in the home via a converter in the property’s roof space. This electricity supplements power supplied from the national grid but because it is pulsed differently, will always be consumed first, saving the homeowner energy costs.
