10kW on the roof and a Sanden heat pump hot water set to only run 9-5. I get credit from the Energy Australia for all the summer months which I spend on on the AC heat pump in winter. 25 year warranty on the panels and 20 on the micro inverters. The economics stack up.

Sanden do seem to be the recommended option for this. The problem is if you have a functional gas, the economics rarely stack up to change. If I knew for sure the Sanden would last 10 years yes, but unlike very simple gas water heaters, heat pumps have a disturbingly high failure rate.*

*At least that was the way it seemed from my research, similar situation 6.66kw solar on roof, functional gas hotwater. We do have both Gas and Heat pump house heating/cooling. Heat pump is much cheaper, gas is much faster, even running the largest size possible ducted heat pump split system. I have the gas warm the house from 6am to 8am, then heat pump take over for the rest of the day.

My Daikin is near instant, even when near freezing outside. The compressor is yuge though, so maybe that’s why.
