The Ultimate Guide to 6.6kW Solar Systems
The 6.6kW solar system has become the most popular choice for homeowners seeking a solar system. This comprehensive guide will provide you with essential information about 6.6kW
A good quality 6.6kW solar system typically costs between $5,500 – $8,000. The average price for a 6.6 kW system in Australia comes in at $6,407. Many variables affect the price. The solar rebate differs for a 6.6kW system depending on where you live; some markets, like Sydney, are more competitive than others, which can also impact prices.
Installations of 6kW (and 6.6kW) solar power systems are a very common sight on rooftops around Australia in 2026, largely due to the ongoing plummeting cost of solar energy components, the still-generous subsidy, and feed-in tariffs. These systems may have 6kW/6.6kW of solar panels, but only a 5kW inverter – see notes on “oversizing” below.
The 6.6kW solar system price in Sydney typically ranges from $4,000 to $6,000 after government rebates. Why Sydney? High energy rates make solar savings more attractive. Abundant sunlight ensures good system performance. The 6.6kW solar system price in Melbourne averages between $4,200 and $6,200.
By oversizing the panels, you can maximise energy output and overcome the efficiency losses associated with rooftop solar panels. The price of a 6.6kW system with a 5kW inverter is the same as for a 6.6kW system, expect to pay between $5,500 - $8,000. The cost of installing a 6.6kW system vs a 5kW system is negligible.
