[QUOTE="solarpete, post: 483736, member: 31576"] We have recently installed solar panels and are trying to optimise their efficiency, we currently have no means to store surplus energy. The system is set up so as to power the HWC as and when there is some solar activity e.g. 9:00 to 11:00 and then again 13:00 to 16:00. What we are finding is that when it powers up at 9:00 there is a relatively short spike of imported (30c/kW) grid power as it brings the HW up to temp - we are then basically exporting (7c/kW) back to the grid for the next 4 to 5 hours. Is there anything we can do to restrict the power to the HWC? i.e. smooth out the current 9:00 spike. [/QUOTE]
