Correctly Sizing Your Solar System Sunshine Coast
The average three-bedroomed household uses about 6,500kWh of energy per year, but what does that mean in terms of the size you need? When choosing a solar system to suit the unique needs of your home or commercial property, size matters, and Logic Solar can help. We suggest talking to your energy supplier or checking your last three bills to get an accurate estimate of your energy consumption. We can then advise on the best solar energy solution for you.

The “size” of a solar photovoltaic (PV) system refers to its maximum output of electricity. What matters is the overall capacity and not the number of panels used.
Most households operate a system of 5 kilowatts. This will generate about 20 kilowatts of energy per day and meet the average Australian household’s needs of between 16 and 20 kilowatts per day.
The above can vary, however. For example, if you’re living by yourself in a residential property, you may only use 8-12kWh per day. In contrast, those living in a household with five people may use 30-40kWh per day. Other factors that will impact energy requirements include using gas for cooking, high energy consumption items such as Pool heating, Air Conditioning systems, EV chargers and many other variables. When it comes to commercial properties, the variables become further complicated.
Planning for Change
Seasonal usage will vary, with air conditioners being used in summer or heaters during winter. So too will usage at certain times of the day. For example, a family that goes to work and school for the day won’t be around to consume much power but will use more at night, when energy companies often charge higher rates (known as Peak periods). These factors will help to determine your maximum requirements. It’s also best that, rather than exported to the grid, your system stores power generated during the day to use at night.
Future change is also a consideration. Whether you’re planning on adding to the family, adding to the house, or even getting an electric car and installing an EV charger, there are many reasons why your energy needs could increase. Therefore, it’s a good idea to think ahead and invest in a larger system now, as this will make it easier to expand later.
In all cases, Logic Solar recommends having one of our professional installers or experienced staff advise you on the best solution for your needs.
