The owner of this villa in North Scotland was seeking advice about their options for attractive solar panels. Whilst wanting to reduce their energy bills, it was important to maintain the aesthetics of the property. There was also a requirement to review the water bills which were high due to the upkeep of a marine fish tank at the property.
EnergyMyWay recommended and installed a GS in-roof system, removing the roof tiles completely and integrating the solar PV panels on a framework that sits flush with the tiled roof. These systems are increasingly popular and work with many types of solar panels and roof finishes. The solar panels will generate free electricity, reducing the bill significantly, as well as earning a tax-free income from the government’s Feed-in Tariff.
To reduce the hot water bills, EnergyMyWay installed an Immersun system, which works with the solar PV panels to divert any excess solar electricity straight to the hot water tank.
Solar Hot Water plates from Viridian were also installed. These have a discrete ‘skylight’ design and are an aesthetically pleasing, efficient way to generate hot water from solar energy. Solar Hot Water systems, also known as Solar Thermal systems, qualify for the government’s Renewable Heat Incentive – see separate case study for more info.
