The PV system was installed 21/11/11 to a due South roof with a 31°pitch.
n the 2nd anniversary, it reported 8203kWh of generation.
From 19/3/2015 a 5kWh Sunamp Heat Battery was added storing excess generation in Phase Change Material and links with the combi boiler to preheat domestic hot water on demand. In the 1st year, this stored 1600kWh providing >70% of the hot water and savings on fuel bills!
On 24/11/2017 we replaced the existing combi with an Intergas Eco RF30. Excess generation is diverted and stored as heat in 2 x 5kWh PCM batteries which are used to preheat cold water before the Intergas combi boiler.
Note; (Generation + Import - Export = Use)
