The number of solar panels needed to run a home in Australia depends on several factors, including the energy consumption of the home, the location of the home, and the efficiency of the solar panels.
On average, a home in Australia consumes around 20 kWh of electricity per day. A typical solar panel has a capacity of around 300 watts, and assuming that it receives 5 hours of direct sunlight per day, it can generate around 1.5 kWh of electricity per day.
Therefore, to generate 20 kWh of electricity per day, a home would require approximately 14 solar panels with a total capacity of 4.2 kW. However, this number can vary depending on the factors mentioned above. It’s important to note that the size and installation of solar panels should be done by a qualified installer, who can assess the specific needs of the home and design a system accordingly.
The real question is… How much can you save with solar panels?
Before you start to calculate the number of solar panels you need, there are several considerations to keep in mind:
Your annual electricity usage, the wattage of the solar panels you’re considering, the estimated production ratio of your solar power system.
You can calculate how many solar panels you need by dividing your yearly electricity usage by your area’s production ratio, and then dividing that number by the power output of your solar panels.

There is no formula we used to estimate the number of solar panels you need to power your home, it requires us to visit your home or site to be as accurate as possible.
*Annual electricity usage
Your annual electricity usage is the amount of energy you use in your home over a full year. Measured in kilowatt-hours (kWh), this number is influenced by the appliances in your home that use electricity and how often you use them. Refrigerators, air conditioning units, small kitchen appliances, lights, chargers, and more all use electricity.
*Solar panel wattage
Also known as a solar panel’s power rating, panel wattage is the electricity output of a specific solar panel under ideal conditions. Wattage is measured in watts (W), and most solar panels fall in the range of 300 – 400+ W of power.
*Production ratios
A solar panel system’s production ratio is the ratio of its estimated energy output over time (in kWh) to its actual system size (in W). These numbers are almost never 1:1 – depending on how many hours of sunlight your system will get (which is primarily based on your geographic location), your production ratio will change accordingly.
For example, a 10 kW system that produces 14 kWh of electricity in a year has a production ratio of 1.4 (14/10 = 1.4)
