How Much Does a 10kW Solar Panel System Canberra Give Power Output?

A 10 kilowatt solar system in Canberra is a powerful and efficient investment to illuminate homes and reduce reliance on the grid.

On average, a 10kW solar system manufactured and installed by a credible installer can generate 35-45kWh per day, converting to around 1200-1500kWh produced monthly and around 15,000-18.5000kWh generated in a year. This translates to powering your household's daily needs, from lighting and appliances to running air conditioners and pool pumps.

This generous supply of energy not only caters to your household needs but also offers the potential to export surplus power back to the grid, earning credits on your energy bills.

However, the power output of your solar system isn't a fixed number; it's influenced by several factors like the amount of sunlight your roof receives, the efficiency of your solar panels, the orientation and the tilt angle of the solar panel, operating temperature of the 10kW solar panel system, among others.

To ensure you maximise your solar energy gains, consider installing your panels in a sunny spot, opting for high-efficiency panels, and orienting them correctly to capture the most sunlight throughout the day.

So, if you want to go green, installing a 10 kilowatt solar system is a smart choice for reducing both your carbon footprint and your monthly utility bills.

How Many Panels Are In a 10kW Solar System? 

As you embark on this journey to become energy independent, one question might linger in your mind: how many solar panels do I need for a 10kW solar panel system? Well, the answer depends on the power output of each panel.

Typically, a 10kW solar system in Canberra, ACT, comprises around 24 to 35 solar panels. Each panel typically generates between 300 to 500 watts of power. So, to reach the desired 10kW capacity, you'll need a combination of panels that add up to that threshold.

The number of panels required for a 10kW solar system depends on the wattage of each panel. Assuming you choose 415W solar panels, which are a common choice, you'll need approximately 24 panels to generate the desired 10kW of power. 

Here's a table describing how many approx. solar panels a 10 kilowatt solar system would need in Canberra, ACT:

Panel Efficiency (Watts)

Number of Panels

Annual Output



13,140 kWh



12,459 kWh



11,780 kWh



11,208 kWh



10,638 kWh


Note - It's important to note that these are just estimates. The actual output may vary depending on some specific factors. 

It's pretty evident from the table that the more efficient the solar panel is, the lesser the number of solar panels you will require, as the best panels are more effective and efficient.

To get an accurate estimate of the number of panels, you'll need for your specific needs, it's best to consult with a qualified solar installer like Kratos Energy. They can assess your property and provide a personalised recommendation based on your energy consumption, roof conditions, specific needs, and local regulations.
