At 3P Solar, our 6.6kW solar system remains one of the most popular choices for residential households across Australia. It offers the perfect balance between affordability, efficiency, and energy output—making it ideal for families looking to cut electricity bills and reduce their carbon footprint without overinvesting.
Whether you’re a new solar user or upgrading from a smaller system, a 6.6kW setup can provide excellent returns with long-term performance and reliability.
A 6.6kW solar panel system refers to a photovoltaic (PV) setup with a combined capacity of 6.6 kilowatts. It typically includes around 16 to 18 high-efficiency solar panels (depending on panel wattage) and a 5kW inverter, which converts the generated DC electricity into usable AC power for your home.
This system size is perfectly suited to medium-sized households with moderate-to-high electricity usage, especially those consuming more power during daylight hours.

The 6.6kW solar system daily output varies slightly depending on factors such as roof orientation, shading, panel quality, and geographical location. On average, you can expect:
The system typically includes:
Daily Output: 24–28 kWh per day
Annual output: Approximately 8,500–10,000 kWh per year
This level of output is usually sufficient to power typical household appliances, air conditioning units, lighting, and more—while still generating surplus energy that can be fed back into the grid for credits under a feed-in tariff scheme.
Pairing your 6.6kW solar system with battery storage gives you even greater control over your energy usage. Instead of sending excess solar energy back to the grid, you can store it for use at night or during power outages
Benefits of adding a battery include:
Reduced grid reliance
Protection from rising energy prices
Backup power during blackouts
Increased energy self-consumption and savings
While the upfront cost is higher, long-term savings and independence can make it a worthwhile investment—especially for families using more energy in the evening.
