What a quality quote includes
Residential Solar: questions
What size system do I need for an Adelaide home?
A 4-person home using 18-22 kWh per day typically needs a 6.6kW system. Heavier consumers (pool, ducted aircon, EV) often want 10kW or larger. Single-phase properties in SA are capped at a 10kVA inverter; three-phase can go to 30kVA.
How much does residential solar cost in Adelaide in 2026?
After the federal STC rebate, a 6.6kW system in Adelaide costs $5,500 to $8,500 for a quality install, and a 10kW system costs $9,000 to $13,500. Premium Tier 1 panels with microinverters can add 10-15% to those ranges.
How long does the install take?
Once SA Power Networks approves your connection (typically 5-10 business days), the install itself takes 1 day. Some systems with batteries or three-phase complications take 2 days.
Do I need to be home for the install?
Not for the full day, but the installer needs access to your meter box, attic / roof space, and a parking spot for the day. They will schedule a final commissioning where you'll need to be present for about 20 minutes.
