6.6 kW suits most 3–4 bedroom Byron Bay homes. Larger homes or those with electric vehicles may need 10 kW+ ($6,300–$12,600). Oversizing slightly is usually good value.
Panel quality
Standard panels ($4,200–$8,900 for 6.6 kW in Byron Bay) use tier-1 brands like Jinko or Trina. Premium panels ($6,800–$11,000) use brands like SunPower, REC, or LG — offering better efficiency and longer warranties.
Battery storage
A 5 kWh battery adds $5,250–$9,450 in Byron Bay. A 10–13 kWh battery adds $8,400–$15,750. 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 Byron Bay. 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 Byron Bay quoted prices. Check for any additional state rebates in your area.
