Solar potential in Cockatoo
Here's what panels on a Cockatoo roof make, month by month, and what that could mean for your bill.
Updated November 2026 · Litmec Electrical, REC-10383
A 6.6 kW north-facing solar system in Cockatoo makes about 9,200 kWh a year, about 3% less than Melbourne: around 35 kWh a day in midsummer and 14 kWh a day in June. East or west-facing roofs make about 84% of that.
On a $450 quarterly bill, that could save roughly $550–800 a year. Cockatoo ranks 361st of the 429 places across Victoria we've modelled for solar output.

These figures use satellite and weather data for Cockatoo from 2005 to 2023 and already allow for heat, wiring and inverter losses. They don't know your roof: shade, pitch and the faces available decide the real number. Try the roof calculator for your own direction and pitch.
Solar in Melbourne's outer south-east and the Yarra Valley
The growth corridor from Berwick to Pakenham and Clyde North is mostly newer homes with simple roofs and young families with high power use, while the Yarra Valley and Dandenong foothills are leafier, cooler and more often shaded by tall trees.
This area is split between the AusNet Services and United Energy networks; your bill shows which one you are on. Your distributor sets how much you can export and approves the connection; we apply for you before anything is ordered.
Cold winters and heating
Winters in Cockatoo are cold, so heating is a big share of most bills. Clear winter days still produce well, and replacing gas or wood heating with reverse-cycle air conditioning run partly on solar is one of the largest savings available. We size for winter heating if you're going electric. Size it from your bill.
Backup when the power goes out
Properties around Cockatoo can be on long rural lines that are exposed to storms and bushfire. Standard solar switches off in a blackout; a battery with backup wiring keeps the fridge, lights, internet and water pump running. How battery backup works.
Shading from trees
Tall trees are common in and around Cockatoo, and shade costs more output than roof direction does. We check shade across the year, including the low winter sun, and use optimisers or microinverters where a few panels can't avoid it.
What solar could save in Cockatoo
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $550–800 a year, or $1,000–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.
