We have 8.8kW of solar panels and an 11.45 kWh battery, we're home all day so can utilise the solar system quite nicely. With Amber, we're still paying $70 to $100 each month during the summer, and over the last 12 mths, we've paid Amber $1635 for electricity, despite the above system. We're regional NSW, so I think our supply rate ($2.05 p/d) is a bit higher than those closer to the cities.
On a good day, we might import 1 or 2 kWh, but with Winter coming, we know the aircon is going to be used in the evening, so this will push up the usage somewhat.
We've tried the VoltCompare.au app, which seems to indicate that Glo's ZH would be much better for us. I'm concerned that our battery isn't that big, and not sure if we'd still get the benefit of ZH with this size? The one advantage is we know that the free 11-2pm period would charge the battery and heat the water whatever the sun is doing, this would help ride out the expensive evening time slot when the aircon is on after work.
Flow, from what I read, seems to be better for bigger batteries?
Thanks in advance for your feedback :)
