Installing a solar energy system is a fantastic way to reduce your electricity bills, cut your pollution and increase the value of your home. Plus, since most solar power systems pay themselves off within 3 to 5 years, you can be confident that your investment in solar power will bring both short and long term rewards! When deciding on which solar power system is best for you, there are a number of questions that first need to be considered, such as:

  • How much electricity do you want to save?
  • What are your long-term energy needs?
  • How much space have you got?
  • What’s your budget?

How much electricity do you want to save?

Before you work this out, you’ll need to know how much electricity you use.

The average household in Australia consumes around 18 kW/h or ‘units’ per day. Use the back of your latest electricity bill to determine how much energy your household consumes. You’ll also find information about past consumption and usage patterns.

Average Daily Production

Now use the table below to determine how much power (on average) common solar energy systems produce state by state.

Average daily production
Location 2 kW 3 kW 4 kW 5 kW
Adelaide 8.4 kWh 12.6 kWh 16.8 kWh 21 kWh
Alice Springs 10 kWh 15 kWh 20 kWh 25 kWh
Brisbane 6.3 kWh 12.6 kWh 16.8 kWh 21 kWh
Canberra 6.45 kWh 12.9 kWh 17.2 kWh 21.5 kWh
Darwin 8.8 kWh 13.2 kWh 17.6 kWh 22 kWh
Hobart 7.0 kWh 10.5 kWh 14.0 kWh 17.5 kWh
Melbourne 7.2 kWh 10.8 kWh 14.4 kWh 18 kWh
Perth 8.8 kWh 13.2 kWh 17.6 kWh 22 kWh
Sydney 7.8 kWh 11.7 kWh 15.6 kWh 19.5 kWh

What are your long-term energy needs?

This is a really important factor to consider. Before you opt for a smaller solar power system, think about how your situation will change in the future.

Are you planning to expand your family, extend your home or purchase equipment/appliances that will use more electricity?

Though it may be more expensive in the short term, installing a larger solar energy system to cover your future needs is a smart, cost-effective strategy that ensures you power bills stay down.

How much roof space is available?

The physical space on your roof and around your property will help determine what size and style solar energy system you should choose. But don’t fret too much about this one. Solargain can fit solar panels to almost any property, even in the most challenging situations.

Our CEC Accredited Installers and Designers will work with you to install a solar energy system that fits the size and shape of your property, so you can make the most out of the sun every day of the year.

What's your budget?

Solar energy systems come in a range of shapes, sizes and prices. Before you determine how much you’re willing to spend, it’s important to do your research and find out how solar panels work, the difference between each brand and what size system will best suit your lifestyle.

Only after knowing these important factors can you truly determine which panels will provide the best value for you and how much you should spend. For a general idea about the size and type of system you’ll need, see below and then visit solar energy packages and specials.
