Why 13kW is the new family-home standard
Household electricity use keeps climbing — heat pumps, induction cooking, EV charging and a battery all reward extra capacity. A 13kW system generates roughly double what a 6.6kW system does, which means more of your usage covered, more export credit, and a battery that actually fills in winter. If your roof and switchboard support it, cost-per-kilowatt is lower than on smaller systems.
Rebates on a 13kW system
Eligible Victorian owner-occupiers can claim the Solar Victoria rebate of up to $1,400 plus an optional $1,400 interest-free loan, and the system earns a large STC incentive that comes straight off the installed price. Adding a battery? The federal Cheaper Home Batteries program discounts the installed battery cost by around 25% (tiered since May 2026). We include every incentive in one fixed quote.

13kW solar system questions
How much does a 13kW solar system cost in Melbourne?
A 13kW system is priced per roof and switchboard, and the STC incentive takes a significant amount off up front. We quote a fixed after-incentive price after a roof assessment — call 0447 347 241 for a free quote.
Is a 13kW solar system too big for a home?
Not any more. 13kW suits larger family homes, all-electric households, EV owners and anyone planning a battery. Bigger systems also make battery charging viable year-round, which is why 13kW has become one of the most popular residential sizes in Australia.
Do I need three-phase power for 13kW?
Usually yes — most 13kW installations pair with three-phase supply, or a compliant export-limited single-phase design. We confirm what your switchboard supports as part of the free assessment.
