Return is calculated using combined bill savings and subsidy earnings. Bill savings are calculated using estimated energy usage and either the electricity price at the time of installation (30 September, 2014) or, for our heating products, the existing fuel type available to the property.
As part of a major self-build refurbishment project, our customer was aiming to achieve as high as possible an energy rating for the property, and to generate as much electrical energy as possible for self-consumption. A follow-on project will look into a suitable solar PV battery storage solution, and the feasibility of utilising a micro-wind turbine.
EnergyMyWay advised on the different renewable energy technologies available, and due to physical constraints and planning issues it was decided that the most cost effective solution was to provide a solar PV system utilising high efficiency SunPower modules, with the view to provide solar battery storage at a later date, after compiling an energy usage profile under occupation. In the meantime, £800 a year tax-free will be paid by the Feed-in Tariff, along with our customer enjoying a long-term lower cost electricity bill.
