Most solar homes export 40–60% of their power for a few cents, then pay peak rates to heat water and charge the car. The problem isn't your panels — it's timing.
Start from your power bill and get an honest system size — in kilowatts and panels — then the part most calculators skip: how much of it you'd actually use. Backed by Australian energy research.
ARENA, UNSW and CSIRO all point to the same fix: move your hot water, car and AC onto surplus solar the moment it's there — automatically. No single-brand product does it across your devices. Powermind is that missing piece — and tells you every decision in plain English.
I'm an environmental scientist in Canberra, and I built Powermind because I kept watching good solar leave for cents while homes bought it back at peak — and nothing on the market fixed the timing across your devices. It's now heading toward release, and I'm inviting a small group of foundation users — solar homes with at least one flexible device (a heat pump hot water system, an EV, or smart aircon) — to help shape it before it goes to market. Foundation users get early access, direct support from me, and a genuine say in which brands and devices we build for first.
