Own the whole bill.
Hot water alone is 15–30% of a home's energy use, and heating is most of the rest. Victoria has made the ending official: from March 2027, gas hot water systems must be replaced with efficient electric at end-of-life, and new homes lose gas connections. The machines below run on the sunlight your roof already makes, including the one parked in your driveway.
Heat pump hot water: the battery you already own
A heat pump heats water about three times more efficiently, and on a midday timer it stores your solar as hot water. Switching from gas saves a typical household around $400 a year, and the rebates stack: Solar Victoria up to $1,000 (or $1,400 locally made) plus a VEU discount, together up to ~$2,030 off.
Hot water in full →Splits: heat and cool on sunlight
Reverse-cycle splits replacing gas ducted or old electric heaters qualify for VEU discounts, run for cents in solar hours, and take the sting out of the 4–9pm peak. Sized room by room, fixed price in writing.
Splits in full →EV chargers: fill the tank from the roof
A smart solar-divert charger sends excess sunlight to the car first: charging for cents per 100 km against roughly $14 on petrol, with a 6.6 kW system's surplus adding 120–180 km of range a day in the sunny months. Wallbox supplied, installed and set to solar-first, typically $1.5–3k, fixed in writing.
