Solar crunch

I’ve been crunching the numbers on our electricity usage and the likely configuration and cost for solar power and solar hot water for our new place wherever it is. Currently we have electric-everything – hot water, heating/cooling, hotplates and oven. Our average daily usage over the past two years has been 31kWh/day of which 17 has been standard tariff and 14 has been off-peak hot water. If we opt for a solar HWS, our electricity usage drops to an average 17kWh/day (excluding any electric boost to the hot water).
