Australian solar, battery, electricity and EV explainers designed to sit alongside the calculators. Start with the topic that matches the decision you are making.
10kW Solar System Australia
A 10 kW rooftop solar system can suit larger homes, high daytime loads, EV charging or battery plans. Roof area and connection limits can be decisive.
10kWh Home Battery Australia
A 10 kWh-class battery can cover a meaningful share of evening usage for many homes, depending on usable capacity and load timing.
13.2kW Solar System Australia
A 13.2 kW array can produce substantial annual energy, but self-consumption, inverter design and export constraints strongly affect its economic value.
13.5kWh Home Battery Australia
A 13.5 kWh-class battery is a common comparison point in Australian residential storage because it can cover substantial overnight energy for many househol
15kW Solar System Australia
A 15 kW residential-scale array may suit very high-load homes or properties electrifying transport and heating, subject to roof and network constraints.
20kWh Home Battery Australia
A 20 kWh-class battery can suit larger homes, high evening usage, long backup targets or properties with substantial solar generation.
6.6kW Solar System Australia
A 6.6 kW array is a common residential size because it can pair with inverter configurations used on many homes, but its suitability depends on load, roof
7kW vs 11kW vs 22kW EV Chargers
Home charging speed is limited by both the EV charger and the vehicle onboard AC charger. Higher wallbox power is useful only when the electrical supply an
Air Conditioner Running Cost Australia
Air-conditioner running cost depends on electrical input, operating hours, compressor load and your tariff—not simply the advertised cooling capacity.
Average Electricity Usage Australia
Household energy use varies with household size, climate, gas versus electric appliances, pools, EVs and heating/cooling.
Cheaper Home Batteries Program 2026
The Australian Government program supports eligible small-scale battery installations through the SRES and is described as providing around a 30% discount
Electricity Cost per kWh Australia 2026
Electricity rates vary by state, distribution area, retailer and tariff structure, so there is no single Australian cents-per-kWh figure that fits every ho
EV Charging Cost at Home Australia
Home EV charging cost is primarily battery energy required divided by charging efficiency, multiplied by the electricity rate that applies when you charge.
EV vs Petrol Running Cost Australia
Energy cost per kilometre can be compared using kWh/100 km for an EV and L/100 km for a petrol vehicle.
How Many Solar Panels Do I Need? Australia
Panel count is determined by target array size and individual panel wattage, but roof layout decides what can actually be installed.
Is a Solar Battery Worth It in Australia?
A battery can improve self-consumption and backup capability, but financial value varies heavily with tariffs, load timing, installed cost and incentive el
Solar Battery Cost Australia 2026
Battery quotes vary widely with usable capacity, inverter architecture, backup capability, switchboard work and incentive treatment.
Solar Export Limits Australia
Distribution networks can limit how much rooftop solar is exported to the grid. Limits can be fixed, zero-export or dynamic depending on network and connec
Solar Feed-in Tariffs Australia
Feed-in tariffs are credits for exported solar electricity and vary by retailer, state, plan and time. They are generally lower than retail import rates.
Solar Panel Cost Australia 2026
Solar pricing varies with system size, hardware, roof complexity, switchboard work and installer scope. Use quote inclusions—not price alone—to compare off
Solar Panels Adelaide: Output & Sizing Guide
The Australian Government lists typical Adelaide solar generation at about 4.2 kWh per installed kW per day averaged over a year.
Solar Panels Brisbane: Output & Sizing Guide
The Australian Government lists typical Brisbane solar generation at about 4.2 kWh per installed kW per day averaged over a year.
Solar Panels Melbourne: Output & Sizing Guide
The Australian Government lists typical Melbourne solar generation at about 3.6 kWh per installed kW per day averaged over a year.
Solar Panels Perth: Output & Sizing Guide
The Australian Government lists typical Perth solar generation at about 4.4 kWh per installed kW per day averaged over a year.
Solar Panels Sydney: Output & Sizing Guide
The Australian Government lists typical Sydney solar generation at about 4.0 kWh per installed kW per day averaged over a year.
Solar Payback Period Australia
Solar payback is driven by installed cost, annual generation, self-consumption, retail tariffs and export value. It should be treated as a range, not a gua
Solar Self-Consumption Explained
Solar self-consumption is the share of solar generation used on-site instead of exported. It is one of the strongest drivers of rooftop-solar bill savings.
What Size Solar Battery Do I Need?
Battery size should follow evening and overnight consumption, backup goals and the amount of excess solar available to recharge it.
