Fact Checked
Switching to solar energy in Australia demands careful thought. With the growing interest in solar panels across the country, it’s essential to understand the solar power requirements for your home.
How do you effectively determine the average number of solar panels needed in Australia? Let’s explore.
Factors to Consider:
When thinking about installing solar panels in Australia, it’s important to understand the specific solar power requirements of the country.
Every Australian household has different needs, and grasping these details ensures you get the right number of solar panels for your home. Let’s look at the main factors to consider.
How Much Power Do You Consume?
Understanding your energy consumption is really important. The typical Australian household’s solar kWh consumption can differ based on various factors such as the number of occupants, appliances used, and lifestyle habits.
To gauge this, evaluate your electricity bills from the past year. For instance, if your bills show a monthly consumption of 540 kWh, you are consuming an average of 18 kWh per day.
How Much Roof Space Do You Have?
The potential solar panel system size for your Australian home largely depends on available roof space. While larger solar panels might yield higher efficiency in Australia, they occupy more space.
For instance, a 300W panel might need about 1.6 square meters. If you have 32 square meters of space, you can potentially fit 20 panels.
How Much Money Do You Want To Spend?
Investing in solar panels in Australia is a long-term commitment. While the initial solar panel cost and sizing in Australia can be substantial, the return on investment, especially with rising electricity prices, is promising.
If you’re aiming to spend around $5,000, you might be able to get a system size of around 5kW, which is suitable for a medium-sized household.
What is Your Primary Goal in Installing Solar Panels?
Are you aiming to drastically reduce electricity bills or primarily focused on adopting green energy solutions Australia promotes?
For instance, if your goal is to be entirely off-grid, you might need more panels and battery storage compared to someone who just wants to reduce their energy bill.
How to Calculate your solar panel needs
Determine Daily Consumption
If your home consumes 18 kWh per day (as seen in your bills), note down this number.
Solar Panel Output
On average, one solar panel, let’s say of 300W, in optimal sunlight conditions, might produce about 1.2 kWh per day in Australia (considering 4 hours of optimal sunlight).
Calculate Number of Panels
Divide your daily consumption by the output of one panel. For our example:
18 kwh 1.2 kWh/panel =15 panels
However, always factor in some inefficiencies – weather conditions, angle of panels, and potential shading. Hence, increasing this number by 20-25% for safety, you might need around 18-20 panels.
It’s always best to get expert advice, as solar yield can vary based on your specific location in Australia, the quality of panels, and hours of sunlight received.
