What Size System!
The 1.5kW solar system makes up about half of all the solar systems ever sold in Australia. That’s because up until 2013, the maximum solar rebate you could receive was for a 1.5kW system. However, thanks to rebate changes, current rebates for solar systems don’t differ according to size. As a result, 1.5kW systems are less commonly installed now than five years ago. That said, a 1.5kW solar system is still a sound investment. Perfect for a smaller household, it delivers great returns for energy efficient homes. Here’s everything you need to know.

How much does it cost?
Prices for a quality 1.5kW solar system range from $2,490 to $3,200. Prices for a quality 6.66kW system range from $4,490 to $6,990 But it’s important to note that price is directly related to size and quality. Although you may find cheaper systems elsewhere, keeping within this price bracket ensures you’re buying a better quality product. And whichever system you purchase, you should also ensure it comes with a manufacturers warranty. If it doesn’t, it’s a sign the system’s of low quality and may not last the distance.
On average, a 1.5kW solar system generates 7 units per day. For the average household, this is enough for a third of your energy use. But if your home is highly energy efficient, a 1.5kW system can offset all your energy usage, while on average the 6.66kW system generates 27 units per day so depending on the average amount your household consumes per day will also determine the size system to install on your roof. As with every solar system, the amount of power generated depends on the amount of sun your location receives, as well as the positioning of your solar system. You’ll also generate more power in the summer months than in winter. But don’t worry, our installers will ensure your system’s positioned to receive as much sun as possible, all year round. Output also depends on the quality of your system. Higher quality systems operate better at higher temperatures and produce better results. So make sure you purchase the best quality panels and inverters you can afford – it’ll pay off in the long run.
How big is it?A 1.5kW solar system has 5 panels – perfect for smaller houses. Each panel measures around 1.6m x 1m, so you’ll need at least 10m2 of roof space. A 6.66kW solar system has 18 panels – perfect for 2-4 adults at home who want the peace of mind knowing that they can produce their own green energy during the day without having to pay for it.

How many kWh is 1 unit?
1 kWh is the amount of energy consumption by 1 kW load in one hour. Therefore, 1 Unit = 1 kWh.
