A 2027 U.S.–China conflict with Australia aligned to the U.S. China trade stops immediately, Taiwan exports are slowed/limited, and China launches large-scale cyber disruption in waves. Planning scenario, not a forecast. Planning scenario, not a forecast. No end date is set.

Renewables and Storage — Australia (Investor-Grade, Rooftop and Home Batteries)

Read the United States briefingReport date 2026-11-07

What happens

The small-scale rooftop addition is around 2.8 gigawatts.
cer.gov.au
The rooftop count is around 270,000 systems.
cer.gov.au
Those two prints are the year rooftop book inside 6.8 gigawatts of renewable capacity added over the year. Approved large-scale stations were just under 4 gigawatts. The rooftop book and the large-scale book are both on the page. Rooftop is the count-heavy side.
cer.gov.au
Solar approvals were a record 3 gigawatts.
cer.gov.au
More than 193,000 valid batteries were installed.
cer.gov.au
Home batteries delivered 4.6 gigawatt-hours.
cer.gov.au
The regulator says that home-battery storage was more than the 12 largest in-service large-scale batteries combined. The comparison is the regulator's. This note does not invent a gigawatt-hour total for those 12 stations. The following-year anticipation is 350,000 to 520,000 batteries and 8 to 12 gigawatt-hours. That range is a projection.
cer.gov.au
The program received more than 55,000 applications.
cer.gov.au
Validated applications represented over 700 megawatt-hours.
cer.gov.au
Nearly 41,000 applications had been validated. Applications represented over 1 gigawatt-hour. The concurrent share is 45 percent.
cer.gov.au
The half-year rooftop print is down 12 percent.
cer.gov.au
The half-year rooftop volume is 1.3 gigawatts.
cer.gov.au
The quarter approval print was 1.5 gigawatts of large-scale capacity, and 2.6 gigawatts had been approved so far when that report was written. The later year print is the just-under-4 gigawatt figure. The two reports are different dates and are not averaged.
cer.gov.au cer.gov.au
The fleet count is over 4.40 million installations.
pv-map.apvi.org.au
Combined capacity is over 47.9 gigawatts.
pv-map.apvi.org.au
That fleet is all PV in the regulator database the institute reads, not a rooftop-only cut. Historically, 50 percent of new installations are registered within one month.
pv-map.apvi.org.au
90 percent of new installations are registered within four months.
pv-map.apvi.org.au
Renewable energy accounted for 43.7 percent of National Electricity Market generation in the year. That share is demand context, not an equipment import share. Utility-scale battery discharge reached 0.6 percent of supplied electricity. That discharge share is also demand context.
cer.gov.au cer.gov.au
A partner-country module share is unpublished. The pivot-table note says partner country and state or territory level data could not be included.
dfat.gov.au

What is counted, what is unpublished, and what a cyber wave can stop

What keeps being installed is the small-scale rooftop book. The small-scale rooftop addition is around 2.8 gigawatts. The rooftop count is around 270,000 systems. The fleet count is over 4.40 million installations. A China trade stop threatens modules only to the extent buyers source them from China. That China module share is unpublished. DFAT could not include partner country on the detailed import pivot. No China module dollar is calculated.
cer.gov.au pv-map.apvi.org.au dfat.gov.au
The product name for the missing share is photovoltaic cells assembled in modules or made up into panels. No Australian dollar value is taken from the tariff search.
hts.usitc.gov
Rooftop work can slow for reasons already printed. The half-year rooftop print is down 12 percent. The page ties that slowdown to customers waiting on the battery program. That is an observed half-year, not a war forecast.
cer.gov.au
Home batteries can keep a separate order book even when rooftop megawatts pause. Validated applications represented over 700 megawatt-hours in the opening window.
cer.gov.au cer.gov.au
Large-scale projects are a smaller count story and a real approval story. Solar approvals were a record 3 gigawatts inside approved large-scale stations of just under 4 gigawatts.
cer.gov.au
Week-1 cyber risk is fleet monitoring and large-plant controls. The Sungrow advisory is the product. The ACSC notes state-sponsored pre-positioning against operational technology in crisis or conflict. Installer shops and home-battery crews are the later direct set. Certificate systems sit in the second wave because they are the registry, not the roof.
cisa.gov cyber.gov.au pv-map.apvi.org.au

How hard, how soon

0–3 months

Short-horizon analog: validated applications represented over 700 megawatt-hours, inside a window that also produced more than 55,000 applications. This is shorter than a half year. A year-over-year peak is not the figure in this band.
cer.gov.au
A monthly module price, a counted week of installations, and days of a module shortage were not on the CER, APVI, or DFAT pages opened. The opened short analog remains over 700 megawatt-hours. The quoted vintage certificate price is 10 dollars and sits in the half-year band as a level, not as a monthly module price.
cer.gov.au pv-map.apvi.org.au dfat.gov.au
The quarter large-scale print of 1.5 gigawatts is cited with that shorter window. It is not the only short figure. Nearly 41,000 applications had been validated in the same window.
cer.gov.au

1–6 months

Half-year analog: the half-year rooftop print is down 12 percent. The half-year rooftop volume is 1.3 gigawatts.
cer.gov.au
The quoted vintage certificate price is 10 dollars. That level can be watched through a half year. It is not a module-price index.
cer.gov.au

12+ months

Full-year scale: the small-scale rooftop addition is around 2.8 gigawatts, home batteries delivered 4.6 gigawatt-hours, and approved large-scale stations were just under 4 gigawatts.
cer.gov.au
Installed base: combined capacity is over 47.9 gigawatts. The fleet count is over 4.40 million installations. The following-year battery range of 350,000 to 520,000 is a projection.
pv-map.apvi.org.au cer.gov.au

Wave 1

Wave 1 direct is inverter suppliers, large-scale solar projects, and large-scale battery projects. Wave 1 indirect is module buyers, because a China stop can delay equipment while the China share stays unpublished and the buyer's own system is not the first target. The Sungrow advisory header prints a CVSS v4 score of 9.5. That score is the product rating for iSolarCloud and WiNet, not a count of Australian plants offline. The electricity, gas, water and waste division was 17 percent of critical-infrastructure incidents. That 17 percent is the ACSC division share, which includes electricity, not a solar-installer outage count. Ordering is a planning inference.

cisa.gov cyber.gov.au dfat.gov.au

Wave 2

Wave 2 direct is project lenders and installer certificate systems. Historically, 50 percent of new installations are registered within one month, so a registry outage is a cash event. Ordering is a planning inference.

pv-map.apvi.org.au cer.gov.au

Wave 3

Wave 3 direct is rooftop installers and home battery installers. The rooftop count is around 270,000 systems. More than 193,000 valid batteries were installed. These are distributed firms. Ordering is a planning inference.

What to do

Day 7

Ask module suppliers for the partner country the official pivot does not publish. Do not fill the gap with an aggregate preview.
dfat.gov.au comtradeapi.un.org
Check rooftop and utility fleets for iSolarCloud version 2.1.6 and prior and for WiNet firmware.
cisa.gov

Day 30

Watch the home-battery window against the opening print. Validated applications represented over 700 megawatt-hours. The program received more than 55,000 applications.
cer.gov.au
Watch registration. Historically, 50 percent of new installations are registered within one month.
pv-map.apvi.org.au

Day 90

Compare the rooftop run-rate with the half-year print. The half-year rooftop print is down 12 percent. The half-year rooftop volume is 1.3 gigawatts.
cer.gov.au
Keep large-scale approvals on their own line. Approved large-scale stations were just under 4 gigawatts. Solar approvals were a record 3 gigawatts.
cer.gov.au

What to watch

Annual rooftop systems, count. Act when an annual rooftop registration count prints below 135,000 systems. Half of the around-270,000 print is 135,000, and that half is calculated. The 135,000 line is a planning line. The regulator does not publish that covenant.
cer.gov.au
Validated home-battery capacity in an opening window, megawatt-hours. Act when validated home-battery capacity in an opening window prints below 700 megawatt-hours. The 700 megawatt-hour line is the printed floor of the opening window and is a planning line. The regulator does not publish that covenant.
cer.gov.au
Annual valid home batteries, count. Act when annual valid home batteries print below 96,500. Half of 193,000 is 96,500, and that half is calculated. The 96,500 line is a planning line. The source count is more than 193,000, so the line is under that floor.
cer.gov.au
Quarterly large-scale approvals, gigawatts. Act when quarterly large-scale approvals print below 1.5 gigawatts. The 1.5 gigawatt line is the opened quarter print and is a planning line, not a covenant.
cer.gov.au

By role

Rooftop installers

Track registrations against the 50 percent within-one-month history.
Keep a manual certificate path if the registry is down.
Do not assume a China module percentage.

pv-map.apvi.org.au dfat.gov.au

Home battery installers

Watch the opening-window floor of 700 megawatt-hours.
Keep the battery count separate from the rooftop megawatt count.

cer.gov.au cer.gov.au

Inverter suppliers and fleet operators

Apply the iSolarCloud and WiNet advisory to Australian fleets.
Treat plant monitoring as week 1 and shop software as later.

cisa.gov cyber.gov.au

Project lenders

Underwrite large-scale credit off the just-under-4 gigawatt approval and the record 3 gigawatt solar slice.
Do not use an average cybercrime cost as the loss figure.

Weekly checks

Rooftop systems registered, count The rooftop count is around 270,000 systems for the year. The planning line is half of that printed figure.

Validated home-battery capacity, megawatt-hours Validated applications represented over 700 megawatt-hours. That opening window is the short analog.
cer.gov.au
Valid home batteries, count More than 193,000 valid batteries were installed. The book is separate from rooftop megawatts.
cer.gov.au
Share of new installations registered within one month Historically, 50 percent of new installations are registered within one month. A drop is a cash-clock signal.
pv-map.apvi.org.au
Large-scale approvals, gigawatts The quarter print was 1.5 gigawatts. The year print was just under 4 gigawatts.
cer.gov.au cer.gov.au

What is not known

The unpublished primary is the Australian partner-country module share. DFAT states that partner country and state or territory level data could not be included on the detailed merchandise pivots.
dfat.gov.au
Australia HS 854143 previews were opened and rejected as shares. The world and China rows are aggregate and not reported. The Taiwan row is empty. Dollars from those three previews are not printed in this note. Other Asia, nes is not used as Taiwan.
comtradeapi.un.org comtradeapi.un.org comtradeapi.un.org comtradeapi.un.org
Calculated planning lines use two figures and are labeled. Half of the around-270,000 rooftop print is 135,000. Half of 193,000 batteries is 96,500. The 700 megawatt-hour line and the 1.5 gigawatt line are the printed floors, marked as planning lines because no covenant was published.
cer.gov.au cer.gov.au
The 43.7 percent, 37 percent, 18 percent, 17 terawatt-hours, 20 terawatt-hours, 40 percent, 35 percent, and 0.6 percent generation figures are demand context. They are not equipment shares. The 12 largest batteries comparison is left in the regulator's words. No missing gigawatt-hour total is invented. Installer employment, days of module inventory, a vendor fleet share, and a household battery price were not on the pages opened. Wave order is a planning inference. The certificate price of 10 dollars is a level, not a shock percent.
