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.
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 much power does it generate?
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.
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 much can I save?
How much money you get back from your solar system depends on how much electricity your system exports, and how much you’re paid for it. However, operating at full capacity, a 1.5kW solar system will save you $105
per billing cycle, while the 6.6kW will save you over $300
per quarter with significant savings added up over time. And remember, the higher quality solar system you buy, the greater your returns will be and the more upfront STC’s Government rebate you’ll be entitled to save.
What’s the average payback period?
A good quality 1.5kW system will deliver a full return on investment within 5 years
while upgrading to the 6.66kW payback period of only 3-4 years.
Use more of your solar power during the daylight hours (and export less power to the grid), and you’ll pay it off in no time.
And regardless of how long it takes to pay off your system, you’ll start saving on your electricity bills from day one – and isn’t that the whole point?
What kind of household does it suit best?
system’s great for a smaller household. So if you’re a retired couple using power throughout the day with an electricity budget of $120 per bill cycle, this may be the perfect system for you.
However, if you are looking to upgrade your old system installed over 7-10 years ago, then we highly recommend upgrading to at least a 6.66kW system that will negate your bill every billing cycle and add tax free ($) credits to your next bill, all year round.
