Home energy, explained

How power moves.
Through your day.

Follow the sunshine through one modelled Perth home. See what your roof supplies, what a battery keeps, and when the street steps in.

Explore a typical home, not a live reading of yours. No bill or contact details needed.

Loading the model of one clear Perth day. A typical home with 6.6kW of solar and no battery uses about 22kWh: the roof covers the middle of the day, and the evening comes from the street.

Next on this page: fourteen days in a row from one PSW-installed home's Tesla monitoring, published with the owners' permission. Each day will sit over this model's clear-sky ceiling, so you can see how a real home's cloudy days, habits and evenings compare.

The dates are chosen before anyone looks at them, so they can't be picked to flatter the system.

Coming soon. No household data is shown yet.

Behind the model

Where the
numbers come from.

Modelled: PSW's day model for a typical Perth home using about 22kWh a day, on a cloudless day, with clear-sky solar for Perth's latitude scaled to the system size. Orientation, shading and Western Power's export limits aren't modelled, so on big systems the export figures are an upper bound. The 13.5kWh, 5kW battery is illustrative, not a recommendation.
Published rates: Synergy Home Plan A1 at 33.26c a kWh, inc GST, from 1 July 2026. DEBS export credit at 10c from 3pm to 9pm and 2c otherwise, ex GST, for the first 50kWh a day. Checked 11 August 2026.
Observed: Where a view shows WA grid batteries, the figures are AEMO's Wholesale Electricity Market averages for April to June 2026, for grid-scale batteries only, not homes.
Placeholders: Appliance power draws are typical figures awaiting sourced rating-plate values.
Not shown: Savings in dollars, how long a battery would last in a blackout, and anything about your particular home. A written quote covers those.
