In October 2018, Spirit installed a PV solar system for Ridge Farm in Buckinghamshire. The system array consisted of 30 x JA Solar 275W panels mounted on a 15 degree pitched roof, orientated just 10 degrees off south. As there is no likely shading and a preferable orientation the system is expected to achieve an output in the region of 7,500kWh per year. The estimated annual savings and tariff income amounts to £1,206 per year, giving an appealing payback period of only seven years. As well as the attractive economic benefits the PV system also has its environmental benefits with the system expected to save 3,880kg of CO2 per annum.
