AE Connect: Solar Power

Size your residential solar power system

For reference, here's what a typical system in each size range usually contains. Then add your own appliances below to get your real result. The guide table doesn't pre-fill anything.

System SizeTypical Household Profile (indicative)
1 kVA – 2 kVALighting, phone/laptop charging, TV, small essential loads
3 kVA – 4 kVAAbove, plus refrigerator and general small appliances
5 kVA – 6.5 kVAAbove, plus one inverter aircon and/or booster pump
7 kVA – 9 kVALarger household, multiple aircons and/or a small borehole pump
10 kVA – 12 kVALarge households with heavy combined cooling, pumping and appliance load

These are indicative sizes for common, standard residential setups, a guide only. Variations in topography, cable run lengths, appliance runtime and site conditions may change the correct size, in which case a dialogue with our team is recommended. Any residential system sized above 12 kVA automatically requires a site assessment.

Your Appliances

For each appliance you use, enter how many you have and how many hours a day you run them. We've suggested a typical power rating for each. Adjust it if you know your actual value.

ApplianceQuantityPower Rating (W)Runtime (hrs/day)
Inside LightsResistiveEnter actual runtime hours
Outside LightsResistiveEnter actual runtime hours (usually night-only)
TVResistiveEnter actual runtime hours
Phone ChargingResistiveEnter runtime hours
LaptopsResistiveEnter runtime hours
MicrowaveResistiveEnter runtime hours (typically short)
RefrigeratorInductiveIt's fine to enter 24 hours. Duty cycle is applied automatically
Aircon (Inverter type)InductiveIt's fine to enter 24 hours. Duty cycle is applied automatically
AC Borehole PumpInductiveEnter actual runtime hours
Booster PumpInductiveEnter actual runtime hours

There's no limit on quantities. Add as many of each appliance as your home needs. If your calculated system exceeds 12kVA, we'll route you straight to a paid engineering consultation instead of a standard result.
