6.6 kW suits most 3–4 bedroom Wollongong homes. Larger homes or those with electric vehicles may need 10 kW+ ($8,100–$12,950). Oversizing slightly is usually good value.
Panel quality
Standard panels ($5,400–$9,200 for 6.6 kW in Wollongong) use tier-1 brands like Jinko or Trina. Premium panels ($7,000–$11,350) use brands like SunPower, REC, or LG — offering better efficiency and longer warranties.
Battery storage
A 5 kWh battery adds $5,400–$9,700 in Wollongong. A 10–13 kWh battery adds $8,650–$16,200. 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 Wollongong. 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 Wollongong quoted prices. Check for any additional state rebates in your area.

Ask about the warranty on panels (25 years is standard), inverter (5–12 years), and workmanship (5–10 years)
4
Check your Wollongong roof condition before installing — it's much cheaper to fix a roof before panels go on

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 Wollongong electricity bill and usage pattern
