How much does it cost?

An averagely priced 6kW solar system can cost anywhere from $3,990 to $9000. Cheaper options are available but price is generally a good indicator of quality. Here at Cooper and Co. Electrical, we only sell the world’s most trusted and reliable brands, ensuring you get maximum return for your investment.

We also ensure all our 6kW solar systems come with a warranty, as well as Australian based support. That way, you’re protected if anything goes wrong, and don’t have the headache of dealing with an overseas based supplier.

How many panels does it have?

A 6kW solar system has 20 solar PV panels. As each panel is around 1.6m by 1m in size, you’ll need at least 40m2 of roof space.

How much power does it generate?

A good quality 6kW solar system generates an average 26.5kW per day – enough to offset an average household’s energy usage.

However, the output of your 6kW solar PV system will vary depending on your location, system positioning and quality. Systems in sunnier locations generate more power (especially in the summer months), as do those positioned to absorb as much direct sunlight as possible. Quality is also an important factor – the higher quality your solar panels and inverter, the better results you’ll get.

That’s why it pays to rely on experts like us. We can advise you on which system’s best for your needs, directing you to the best brands on the market. And our professional installers will position your system so it absorbs as much sunlight as possible, all year round.

How much can I save?

Assuming your system is of a high quality, a 6kW solar PV system can save you as much as $400 per electricity bill cycle. However, actual returns are more likely to range from $200 to $350 per bill cycle.

And remember – the more solar power you use during daylight hours, the greater your electricity savings will be. So if you use a large amount of electricity while the sun’s shining, a 6.6kW system’s a great choice.

What’s the average payback period?

High quality 6.6kW solar PV systems pay for themselves in around 2.5 to 4 years. But with solar, your savings begin on day one. As soon as your 6.6kW solar PV system starts generating power, you’re saving on your electricity bills; savings that will make a significant difference over the life of your solar system.

What kind of household does it suit best?

6.6kW solar systems are perfect for medium to large families. They’re a great choice for a large family with significant energy needs. So if you’ve got a pool, ducted reverse cycle air conditioning and a spa, this is the perfect system for you.
