6.6 kW suits most 3–4 bedroom Adelaide homes. Larger homes or those with electric vehicles may need 10 kW+ ($5,500–$11,050). Oversizing slightly is usually good value.
Panel quality
Standard panels ($3,675–$7,800 for 6.6 kW in Adelaide) use tier-1 brands like Jinko or Trina. Premium panels ($6,000–$9,650) use brands like SunPower, REC, or LG — offering better efficiency and longer warranties.
Battery storage
A 5 kWh battery adds $4,600–$8,300 in Adelaide. A 10–13 kWh battery adds $7,350–$13,800. Batteries make most financial sense if you have high evening electricity usage or time-of-use tariffs.
Roof type & orientation
North-facing roofs generate the most energy in Adelaide. Tile roofs are standard cost; tin/metal is slightly easier. Flat or complex roofs may need tilt frames, adding $500–$1,500.
Inverter type
String inverters are standard and cheaper. Micro-inverters or optimisers add $1,000–$2,500 but perform better with shading or complex roof layouts.
Government rebates
Federal STCs (Small-scale Technology Certificates) reduce the upfront cost — already factored into most Adelaide quoted prices. Check for any additional state rebates in your area.
How to Save Money on Solar & Battery in Adelaide
1
Get quotes from CEC-accredited Adelaide installers — prices and system quality vary significantly
2
Compare the total cost per watt, not just the headline price — cheaper systems may use inferior components
3
Ask about the warranty on panels (25 years is standard), inverter (5–12 years), and workmanship (5–10 years)
4
Check your Adelaide roof condition before installing — it's much cheaper to fix a roof before panels go on
5
Consider adding a battery-ready hybrid inverter now even if you don't add a battery immediately
6
Ask for a detailed savings estimate based on your actual Adelaide electricity bill and usage pattern
