How much does a solar & battery cost in Melbourne?
The 6.6 kW system Melbourne searches for most is $4,200–$8,900 installed in our table, $6,300 typically, or $6,800–$11,000 with premium panels. Step up to 10 kW and the band moves to $6,300–$12,600; a 13 kW array for a large house is $10,500–$16,800. A 5 kWh battery adds $5,250–$9,450 and a 10 to 13 kWh unit $8,400–$15,750. These prices already have the federal STC discount taken off, GST included. Melbourne's winter is the catch: the city station's average July maximum is only 13.5 °C (BOM averages), and the short, grey days are when output falls away, so sizing here is a conversation about covering June and July, not January.

How Solar Costs Vary Across Melbourne
Melbourne solar prices here are city-wide. A standard 6.6 kW system is $4,200–$8,900 and a Tesla Powerwall 3 $12,600–$17,850. Melbourne postcodes are in zone 4 of the Clean Energy Regulator’s solar zone table, against zone 3 for Sydney and Brisbane — each zone represents the level of solar radiation, and it is one of the factors in how many certificates a system earns.
Solar panels price in Melbourne (2026): 6.6 kW and 10 kW systems, premium panels and batteries
Solar panels in Melbourne cost $4,200–$8,900 for a 6.6 kW system installed with standard panels, with $6,300 typical, and $6,800–$11,000 with premium panels. A 10 kW system is $6,300–$12,600 installed. Those prices are after the federal certificates are taken off; the Victorian solar rebate and interest-free loan, where you are eligible, come off on top.
| Job | Low | Typical | High |

| 6.6 kW system (premium panels) | $6,800 | $8,400 | $11,000 |
| 10 kW system (standard panels) | $6,300 | $9,450 | $12,600 |

| Battery 10–13 kWh (mid-range) | $8,400 | $11,550 | $15,750 |
| Hybrid inverter upgrade (battery-ready swap on a typical home system, no battery) | $2,100 | $3,150 | $4,200 |
Adding a battery in Melbourne: a 5 kWh battery is $5,250–$9,450 installed and a 10–13 kWh battery $8,400–$15,750; an existing system needs a hybrid inverter ($2,100–$4,200) or a battery with its own. Melbourne's winter sun means a battery is sized for the evening peak rather than for going off grid; ask the installer to model it on your actual usage before buying.
What moves a solar quote in Melbourne:
- System size: 6.6 kW is the common household size; 10 kW suits larger homes, pools, air conditioning or a battery.
- Panels and inverter: standard tier-one panels are the base; premium panels and a hybrid inverter ready for a battery cost more.
- Roof: tile roofs, steep pitches, two storeys and multiple orientations add installation time; a flat roof needs tilt frames.
- Switchboard and metering: an old switchboard may need an upgrade before the system can be connected.
- Rebates and certificates: the federal certificates and any Victorian incentive change over time and are taken off the quote; ask for the price after them.
For solar quotes in Melbourne that compare, ask for the panel and inverter models, the system size, the price after rebates and whether the switchboard is included.
What Affects Solar & Battery Costs in Melbourne
Zone 4 and the STC discount
How many small-scale technology certificates a system earns depends partly on where it is. Central Melbourne, postcode 3000, is in solar zone 4 of 4 on the Clean Energy Regulator table with a rating of 1.185, the lowest of the four (zone 1 is rated 1.622). Fewer certificates per kilowatt means the STC discount on a Melbourne quote is smaller than the same system would get in a sunnier zone, which is part of why the installed price lands where it does.
The Solar Homes rebate
Eligible Victorian households can get a Solar Homes rebate of up to $1,400 towards solar panels, worked out as up to half the purchase cost after the STC discount has come off, with the option of a matching interest-free loan repaid monthly over four years (Solar Victoria). You need to be the owner-occupier, the owners' combined taxable income must be under $150,000 a year, and the address must not have had solar installed in the last ten years.
Batteries: the state loan has closed
Solar Victoria is no longer taking applications for its interest-free solar battery loans and points households to the Commonwealth's Cheaper Home Batteries Program instead (Solar Victoria). Under that program the accredited installer takes the discount off the price up front or pays it as a rebate afterwards, and the battery has to be connected to a solar system (DCCEEW). The battery bands on this page are $5,250–$9,450 for 5 kWh and $8,400–$15,750 for the mid-range size.
Terrace roofs and shared roofs
Terraces and townhouses make up 16.2% of Melbourne's dwellings and flats another 15.6% (ABS 2021 Census). A terrace roof is often split between a north and a south pitch, which pushes the installer towards optimisers or micro-inverters so a shaded string does not drag the rest down. On a unit the roof belongs to the owners corporation as common property, and it decides who may use it before any quote is worth signing.
Inverters, new and replacement
People in Melbourne ask about inverter prices on their own, and the answer is $1,050–$3,150 to swap a failed string inverter like for like. Going to a hybrid inverter that is ready for a battery later, without buying the battery now, is $2,100–$4,200. A string inverter is the cheap default; optimisers or micro-inverters cost more and earn it on shaded or multi-pitch roofs.
Keeping the panels working
Melbourne's 648.3 mm of rain a year falls in every month, with October the wettest at 66.0 mm (BOM averages), and regular rain rinses most dust off the glass, so cleaning at $160–$420 a visit is an occasional job rather than a routine. A system health check is $160–$370, worth booking if the monitoring app shows a drop you cannot explain.
Standard or premium panels
The premium band is $6,800–$11,000 at 6.6 kW and $10,500–$15,750 at 10 kW, against $4,200–$8,900 and $6,300–$12,600 for standard panels. What the extra buys is usually a higher efficiency per square metre of roof, which matters on a small Melbourne roof, and a longer product warranty, which matters on any roof.
