How much does it cost?

Good quality 5kW solar systems range in price from $3,990 to $8,000. Although cheaper systems are available, you always get what you pay for. Sticking within this price range ensures you’re purchasing a good quality solar PV system.

Along with price, you should also consider warranty protection. Things can, and sometimes do go wrong – so ensure your solar system is protected with a comprehensive warranty and Australian based support. Every 5kW solar system we sell comes with both – just another way we ensure you get the most out of your investment.

How many panels does it have?

Based on the industry standard 275W panels, a 5kW solar system consist of 18 solar PV panels. If you choose our 390W Hyundai All Black Shingled panels however, this will reduce to just 14 panels. This means you’ll need at minimum 30m2 of roof space, as each panel is around 1.6m by 1m in size.

How much power does it generate?

On average, a good quality 5kW solar system generates an average 22kW per day – enough to easily offset a typical Australian household’s entire energy usage.

The amount of power your 5kW solar system generates depends on three things: location, positioning and quality. Locations receiving large amounts of sunlight with less cloud cover are the best places for solar. However, if you’re in a less sunny location, you’ll still benefit – particularly if you purchase the highest quality system, invest in technologies such as power optimisers, and position it correctly.

That’s why we recommend you purchase the highest quality panels and inverters you can afford. They produce the best results and will put more money back in your pocket over a longer period.

We also suggest you take advantage of our installers’ expertise – they know where, and how to position your system so it absorbs the most direct sunlight possible. With their help, you’ll generate the maximum amount of energy possible, 365 days a year.

How much can I save?

One of the best performing systems available, a 5kW solar system can save you as much as $350 per electricity bill cycle. However, your actual savings are more likely to be between $180 and $300 per cycle – more than enough to cover your household’s entire energy usage.

As with any solar system, the amount you get back depends on how much electricity you use, and when. Use most (or all) of your solar power during the daylight hours, and you’ll get the most money back. That’s because the amount you receive from your feed-in tariff (for power exported to the grid) is significantly less than the amount you pay to buy electricity from the grid. So the more solar power you use, the more you’ll save.

What’s the average payback period?

A good quality 5kW solar system will have fully paid for itself within 2.5 to 4 years. It’s worth remembering the less power you export back to the grid, the less time it will take to pay off your system.

What kind of household does it suit best?

5kW solar systems are perfect for medium to large households using larger amounts of electricity. So if you have teenage kids, or a pool and reverse cycle air conditioning, this is the system for you. It suits an electricity budget of $350 or more per bill cycle.
