EvoEnergy examined the average annual system outputs for solar panel installations for every city in the UK to calculate the annual energy savings.
|System Cost||£6142||Based on 2.88kWp system; Suntellite 240 wP Panel & Delta Inverter; August 2012|
|Price per kWh||£0.1439||Source: http://www.energysavingtrust.org.uk/Using-this-site/Our-calculations|
|Export tariff rate||£0.045||Source: http://www.decc.gov.uk/en/content/cms/news/pn12_066/pn12_066.aspx|
|Generation tariff rate||£0.16||Source: http://www.decc.gov.uk/en/content/cms/news/pn12_066/pn12_066.aspx|
Total Annual benfit refers to: bill savings plus generation and export tariff payments, per annum
EvoEnergy assume that an average household will use 50% of the energy generated, and export 50% back to the grid
EvoEnergy assume that a typical system would be situated in a due south position, with an elevation of 35 degrees
