How much does a 7kW solar system cost?

Good quality 7kW solar systems range in price from $7,300 to $10,900.

Cheaper systems are available, but may not deliver the results you’re after. Sticking within this price bracket ensures you’re purchasing a higher quality system guaranteed to perform well over time. Higher quality systems also come with full manufacturers replacement warranty and local support, providing a safeguard in the unlikely event something goes wrong.

How big is it?

A 7kW solar system has 21 to 28 panels – perfect for an average sized house. As the average solar panel is 1.6m x 1m, you’ll need around 34 to 45 square metres of roof space.

How much power does 7kW solar system generate?

On average, a 7kW solar system generates an average 31kW per day.

However, actual output varies according to your geographic location and climate, orientation and pitch of your solar panels, as well as roof shading. But don’t worry – our technicians know how to position your panels for maximum efficiency, ensuring you generate the most power possible.

Output also depends on the quality of your panels and inverter. Higher quality systems perform better under high temperatures and deliver reliable results over the long term, which is why it’s worth investing in the highest quality system you can afford.

How much can I save?

How much you get back from your 7kW solar system depends on how much solar energy you consume, and how much you export back to the grid. However, operating at full capacity, a 7kW system will save you around $300 to $450 per billing cycle – significant savings that will only increase as the price of electricity continues to soar. And remember, the higher quality system you buy, the higher your savings are likely to be.

What’s the average payback period?

A good quality 7kW solar system will have paid for itself within 2.5 to 4 years. The power it generates is far more valuable when consumed than exported back to the grid. So if you use as much of the power your system generates as possible, you’ll see a return on your investment in no time.

What kind of household does it suit best?

A 7kW solar system is perfect for a large household with reverse cycle air-conditioning, a pool, and an electricity budget of $500 plus per cycle.
