Mr & Mrs Fulton, Tavistock
The Fulton's and there family of 4 children live in a 19th century, 6 bedroom, detached house in Tavistock; a small rural town on the outskirts of Plymouth. The front elevation of the house is ESE facing with a roof space of 52 meters squared at an inclination of 40° degrees, while the right side elevation is SSW facing and has a 60 square metered roof space also at an inclination of 40° degrees.
When Mr & Mrs Fulton first approached us here at Enlighten Systems, our PV engineer attended their site to give them a quotation for a Solar Photovoltaic installation. However upon arrival and conversation with Mr & Mrs Fulton it became apparent that Solar Thermal may also be a viable renewable technology due to their annual oil consumptions and the roof space available on the property. That prompted us to also undertake Solar Thermal survey, which was fittingly accepted and the subsequent installations took place.
Enlighten Systems install a 3kWp Solar Photovoltaic system with 14 Schuco panels and a SMA inverter, along with a 3 Glow-Worm Flat Plate panel Solar Thermal system. As with all of our products used on any installation, these will allow for maximum efficiency and generate the best possible outcomes. At Enlighten Systems we estimate that the Solar Photovoltaic system will generate 2,191.2kWh of electricity and reduce 1,244.60kg of CO² emissions annually. These figures are based on National Government SAP calculations, however due to higher irradiation factors in the South West this system should in reality exceed National Averages.
This Solar Photovoltaic system should generate £993.00 through tax free Feed-in-Tariff payments, at a rate of 43.3p per kWh generated, with a further £179.00 being saved through electricity payments. Additionally we estimate that £99.30 will also be earned through exporting excess energy back to the grid. As a result, Mr & Mrs Fulton total income/savings per year are £993.55 which is index linked for 25 years, resulting in a 10 year payback period, and a profit of £23,189.25 in 25 years.
In terms of the Solar Thermal system, we estimate that the system will be exposed to 1,004kWh of Solar Radiation per metre squared each year. This will save the Fulton household 2,310kWh of Solar Water Heating and 612kg of CO² emissions annually. However, as with the Solar Photovoltaic SAP calculations, these figures are based on National Averages, that due to the geographical location could be surpassed.
This Solar Thermal system should generate a saving on Oil consumption of around £81.00 per year, however as we are MCS registered installers Mr & Mrs Fulton will also receive payments from the Renewable Heat Incentive (R.H.I) when the scheme is finalised by the Department of Energy and Climate Change.
