Brisbane has seen a surge in solar panel installations over the past few years—and for good reason.
With rising electricity bills, frequent weather-related power outages, and increasing environmental awareness, more households are choosing to take control of their energy use.
While going solar is already a smart step, pairing your solar panels with battery storage is now becoming the new standard.
Among the most popular setups for Australian homes are the 6.6kW and 13kW solar systems.
When combined with reliable battery options like Sigenergy, these systems offer homeowners a chance to reduce their electricity bills, gain energy independence, and increase their return on investment.
In this blog, we’ll explore why Brisbane homeowners are choosing 6.6kW and 13kW solar systems with Sigenergy batteries—and whether this setup is the right fit for your household.
Why 6.6kW and 13kW Solar Systems Are Popular in Brisbane
6.6kW: The Go-To System for Average Homes
The 6.6kW solar system is one of the most commonly installed setups across Australia. It’s ideal for small to medium-sized homes, and it’s often the maximum system size eligible for STC (Small-scale Technology Certificates) rebates without additional grid approval.
A 6.6kW system generally produces around 25–30kWh per day, depending on the season and roof orientation. This output is usually enough to cover daytime energy usage for most families, especially when household members are home during the day.
13kW: Designed for High Usage Households
A 13kW solar system is suitable for larger families, homes with electric vehicles, or properties with higher electricity consumption due to air conditioning, pool pumps, or home offices.
With potential daily output exceeding 50kWh, a 13kW system offers excellent long-term value—especially when combined with a high-capacity battery.
Given Brisbane’s sunny climate and generous roof space in suburban areas, many homeowners are upgrading or installing larger systems to future-proof their energy needs.

Battery Options with 6.6kW Solar Systems
For most standard Brisbane homes, a 6.6kW system combined with the right-sized Sigenergy battery offers a practical and efficient energy solution.
Recommended Pairings:
- 6.6kW + 10kWh Battery: Ideal for households with basic night-time use—covers essentials like lighting, refrigeration, and device charging.
- 6.6kW + 15kWh Battery: Supports more appliances and activities like laundry, entertainment systems, and moderate pool or garden pump usage.
- 6.6kW + 16kWh Battery: A great option for growing families or homeowners planning for future energy upgrades.
Battery Options with 13kW Solar Systems
Larger solar systems offer more power during the day—but without enough storage, much of that energy could be wasted. Pairing your 13kW solar system with a scalable Sigenergy battery ensures you make the most of your investment.
Recommended Pairings:
- 13kW + 10kWh Battery: Entry-level storage, useful for those focused on partial offset or backup support.
- 13kW + 15kWh Battery: Balanced solution for moderate night-time consumption.
- 13kW + 16kWh Battery: Ideal for families using appliances throughout the evening.
- 13kW + 20kWh Battery: Perfect for EV charging and high consumption patterns.
- 13kW + 24–25kWh Battery: Maximum flexibility for full-day and night usage, or full off-grid aspirations.
What Does a 6.6kW Solar System with Battery Cost in Brisbane?
The cost of a solar + battery setup depends on several factors: the inverter brand, the size of the battery, the site complexity, and available rebates.
- A 6.6kW solar system with a battery generally starts from $9,000 to $15,000+ (depending on battery size and features).
- A 13kW solar system with a battery can range from $16,000 to $25,000+.
Queensland residents may qualify for federal and state incentives that reduce upfront costs. The STC rebate for solar systems and battery grants or loans (where available) make installation more affordable.
