6.6 kW suits most 3–4 bedroom Geelong homes. Larger homes or those with electric vehicles may need 10 kW+ ($5,600–$11,150). Oversizing slightly is usually good value.
Panel quality
Standard panels ($3,725–$7,900 for 6.6 kW in Geelong) use tier-1 brands like Jinko or Trina. Premium panels ($6,050–$9,750) use brands like SunPower, REC, or LG — offering better efficiency and longer warranties.
Battery storage
A 5 kWh battery adds $4,650–$8,350 in Geelong. A 10–13 kWh battery adds $7,450–$13,950. 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 Geelong. 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 Geelong quoted prices. Check for any additional state rebates in your area.
How to Save Money on Solar & Battery in Geelong
1
Get quotes from CEC-accredited Geelong 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 Geelong 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 Geelong electricity bill and usage pattern
