The PV system was installed on 21/11/11 to a due South roof with a 31°pitch. On the 2nd anniversary, it reported 8203kWh of generation.
From 19/3/2015 a 5kWh SunampPV 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 >75% of the hot water and savings on fuel bills!
On 17/6/16 we increased the storage from 5kWh to 10kWh and look forward to saving even more generation. (Generation + Import - Export = Use)
Economy 10 off-peak meter has been added and we plan to make further changes to use more Solar PV generation soon.
