Who is this for?
Most household power gets used after dark, which is why a battery does the heavy lifting at home.

Your Usage Pattern
10%65%
Of all the power your home uses, how much goes before dark. Most homes are 40-50%. This is about your household, not your panels - how much of your solar you actually use is worked out for you below.
This is a typical profile, not your meter. Nobody knows the real day/night split
until we read an actual bill — and it is the number every figure on this page hangs off.
We check it on the free site visit and requote if it moves.
Hot water on a timer, pool pump, EV charging, dishwasher and washing on a delay start.
Typical: hot water 8–10 · pool pump 4–6 · EV 10. This is the cheapest win on
the job, and it takes the midday surplus before the battery does — using a kWh as you
make it beats storing it and losing 10% in the round trip. Shift first, then size the battery
for whatever is genuinely left after dark.
Already on an off-peak rate (about 22c), so moving it to solar saves that, not the full 33c. Worth doing — just honest about the size of it.
Single-phase homes export at max 5 kW — big systems earn less feed-in unless three-phase.

Want this modelled on your actual roof?
Everything above is an estimate. It assumes a typical split between daytime and after-dark use, and a well-oriented roof — because at this point we have never seen your place.
Before you spend anything, we build the real thing: your roof traced off high-resolution aerial imagery, every panel placed where it will actually go, the tilt and orientation of each roof plane taken properly into account, and a 3D shading study that accounts for your trees, your neighbour’s, and your own gables — hour by hour, right through the year.
What comes back is production for your address and your roof, not for a typical Sunshine Coast one — plus the panel layout you would actually get, so you can see it before anybody drills a hole.
We design in Pylon, the platform a lot of
Australian installers use for this. It is part of the free site assessment —
there is no charge for it and no obligation to go ahead.
⚠️ Estimation only. Actual savings, production and costs vary based on roof orientation, shading, usage patterns, retailer tariffs and site-specific factors. Book a free assessment for a fixed-price quote.
