Australian operating systems / 30-day window
Auto briefing
Peak rooftop PV in Western Australia / SWIS is 15.2% above its prior 29-observation median.
1,820 MW on 2026-08-11, against 1,579 MW. Ranked by robust distance from the retained median; this is observed context, not a forecast or causal claim.

Continue investigationFor a century, energy was an engineering question: build the plant, string the wire, meter the load. It is now a data question. The cost of a kilowatt-hour, the yield of a panel, the direction of a subsidy and the drift of the climate that powers it all move faster than any single operator can track by hand.
Solar Analytica holds that evidence in one place and keeps it honest. Every figure names its source. Nothing is modelled where it can be measured. And attribution is only the floor: wherever the source is public, the number is reproducible. Run the same records through the published method and you arrive at the same figure. The result is a reading of the market that holds the same shape whether you are pricing one roof or a national build-out.
The point of keeping the record this way is what it does to the forward view. A projection fed from a reconciled record starts better, and a projection published over one gets marked: our scenario models name the roadmap figures observed data has already overtaken, and the TBx Capture Index scores what every NEM battery earned against a perfect-foresight benchmark. We do not claim to see the future more clearly. We make claims about the future accountable to the record.

The Clean Energy Regulator rated 62.45 per cent of inspected battery systems substandard against 18.6 per cent for rooftop solar, but the unsafe rate did not move with it. What a system-level rating counts, where the flagged items sit, and a state spread running from 37.6 to 77.3 per cent.
