These figures use satellite and weather data for Trentham 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 Ballarat and the Central Highlands
Ballarat sits around 400 m above sea level, so winters are cold and frosty and heating is a big part of most power bills. Clear cold days still produce well, and replacing gas or wood heating with reverse-cycle air conditioning powered partly by solar is one of the biggest savings available here. Older goldfields-era homes and big new estates such as Lucas and Alfredton sit side by side.
Ballarat and the Central Highlands are on the Powercor network. 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 Trentham 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 Trentham 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 Trentham, 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 Trentham
For a home paying $450 a quarter with someone in some days, the calculator suggests a 6.6 kW system saving about $600–800 a year, or $1,000–1,400 with a 10 kWh battery. Your own bill gives a better answer: use the calculator below.

Can solar keep my power on during outages in Trentham?
Only with a battery designed for backup. Standard solar shuts down in a blackout. A backup-capable battery keeps chosen circuits, such as the fridge, lights, internet and water pump, running, and the panels recharge it in daylight.
