Project details
Located in a popular coastal resort, the client’s cottage was undergoing a complete refurbishment.
To satisfy planning requirements and ensure the support of local residents, Solarsense developed a bespoke, integrated 7.7 kWp solar roof for the client. To ensure the efficiency of the system Solarsense designed and installed bespoke flashing with ventilation holes to the ridge and eaves, coloured to match.
Incorporating solar PV, solar thermal, energy efficient lighting and a bespoke flashing/cooling system, the roof provides enough energy to power and heat the cottage as well as charge the owners’ electric vehicle. Heating for the cottage is electric and is fed from the solar PV system with excess electricity diverted to an immersion tank.
The 4m solar thermal system supplies a space- saving side-mounted, unvented cylinder with any excess sent to a dual energy towel rail. A second cylinder supplies hot water for the outside hot tub.
All lighting in the cottage is LED and a personal EV charge-point was installed to charge the client’s electric car from the free solar energy.
As a result of the complete solar roof, the cottage is now an annual net exporter of energy. The system generates 6,050 kWh per year – 2,050 more than the average UK household.
Generation to date has been 10% above initial predictions and the owners running costs have been reduced by 90%.
This pioneering project has won two national awards including “Domestic Rooftop” at the Solar Power Portal Awards and “Best Project” at the British Renewable Energy Awards.
