2kW Solar System

Not as popular as larger systems, a 2kW solar system is still a great option for a smaller household. This is particularly true if your home’s empty between 9am and 4pm weekdays, and you don’t have access to a particularly generous feed-in tariff. And with solar rebates currently available, now’s the time to buy. Here are the details you need to know.

How much does it cost?

2kW solar systems range in price from $2,690 to $4,100. Cheaper systems are available, but remember price is a good indication of quality. At Infinite Energy we’re driven by quality and results, so rest assured if you buy a solar system from us, it’s one of the world’s best.

Regardless of the type or size of solar system you purchase, you should always ensure it comes with a warranty. That way, you’re protected if things go wrong. That’s why all our 2kW solar systems come with a full warranty and Australian based support.

How many panels does it have?

A 2kW system has 6 solar panels – a great choice for a smaller house. 250W panels are about 1.6m by 1m, so you’ll need at least 13m2 of roof space.

How much power does it generate?

On average, a 2kW solar system generates 9 units per day – around half the electricity usage of a modest Aussie household.

But the amount your 2kW solar system will generate depends on how much sun your location receives, as well as system positioning. You’ll generate less power in winter than in summer, and sunnier locations will obviously produce greater benefits.

That’s why it’s imperative your system is positioned to receive the optimal amount of sunshine, with as little shade as possible. Our fully trained installers will ensure your 2kW system’s perfectly positioned, ready to absorb as much sun as possible, all year round.

As we mentioned earlier, quality is a big deal. Purchasing the best quality solar panels and inverters you can afford means your system will operate more efficiently, giving you the best return on your investment.

How much can I save?

The amount of money you save from your solar system depends on when (and how much) electricity you use in your home. A 2kW system generates about half the electricity used in an average home and can save you as much as $145 per electricity bill cycle. However, savings of $90 per billing cycle are more likely.

Again, how much you save depends on the quality of your system. Higher quality systems generate more power over the long term, producing great results well after your system’s paid for. So it makes sense to invest in the highest quality system you can afford.

What’s the average payback period?

Assuming you buy a good quality system, a 2kW solar system will pay for itself within 4 years. However, you’ll be saving money on your electricity bills from the time of installation, so the payback period’s really secondary isn’t it?

What kind of household does it suit best?

2kW solar systems are great for smaller households using electricity throughout the day, or households that are empty throughout the day. If you’re operating on an electricity budget of $150 per cycle, a solar system of this size will deliver significant savings.

Working out which solar system’s right for your needs can be difficult, and there are lots of options to choose from. That’s why we’re here to help. Give us a call on 1300 074 669 to discuss your options – we’re sure to have a solar system that’s right for your household, lifestyle and budget.
