13kW Solar System Price, Output, and Savings in Sydney

A 13kW solar system offers substantial benefits for large Sydney households. By considering factors like system quality, power usage patterns, and microinverter technology, you can maximise your investment and experience significant savings on your electricity bills.

Thanks to dropping prices and government incentives, 10kW-15kW systems are becoming increasingly popular. A high-quality 13kW system, including a top-tier inverter and premium solar panels, can start around $10,500 fully installed. That pricing is after the rebate.

In Australia, the Small-Scale Renewable Energy Scheme (SRES) offers rebates that can significantly reduce the upfront cost of your system. This incentive helps households to slowly transition to solar energy.

There are more cheaper options available in the market. However, lower-priced systems may use less reliable panels with shorter lifespans and lower overall output.

Here at 1KOMMA5°, we focus on quality and performance. That's why we recommend using premium brands that offer high efficiency with excellent warranties. This ensures your system produces maximum power for years to come.

For a large system like 13kW, we install solar panels from Trina's Vertex Series and Enphase Microinverter. Trina and Enphase are known for their best-value products and reliability. These recommended brands were based on our successful installations over the years.

13kW Solar System Output

Estimates suggest a 13kW system facing north in Sydney will produce an average of 51kWh daily. However, our systems often outperform expectations, thanks to high-quality components.

As we can expect, your daily average energy output is higher during the summer season than in winter. On a sunny summer day, you could even generate over 70kWh! That's enough power to offset your daytime energy use.

Because a 13kW system can produce so much power, you might want to consider ways to use it all.

We recommend installing your panels across multiple roof sections to spread power generation throughout the day. Battery storage can also be a great option. It allows you to use extra solar power in the evenings when the grid produces less electricity and rates are often higher.

A 13kW Solar System - The Key Numbers

How Much Will a 13kW Solar System Save Me?

A 13kW system can significantly reduce your power bills, saving you up to $1,000 to $1,300 per quarter. However, these savings depend on your energy usage during the day.

To maximise your return, you'll ideally use a lot of power when your system is generating the most. For instance, large families or households with pools and air conditioning are good candidates for large solar systems.

How Many Panels in a 13kW Solar System?

The number of panels depends on their efficiency. High-efficiency panels allow us to use fewer panels while still achieving the desired output.

A 13kW system can use 34 high-efficiency 390W panels instead of 47 standard 275W panels. It not only saves your roof space but can also potentially improve the aesthetics of your solar installation.

13kW Microinverter System

For larger systems like 13kW, we highly suggest using microinverters. Microinverters make each solar panel independent, allowing for more flexible panel placement and maximising power output in all conditions.

This technology is especially useful if you want some panels facing west to capture the afternoon sun for time-of-use billing. Microinverters also bypass a potential weak link in traditional systems - the central inverter.

If the central inverter fails, your entire system goes down. With microinverters, even if one panel experiences an issue, the rest of your system continues to generate power.

Microinverters offer several advantages, especially for large systems. To learn more about the benefits of microinverters, check out our guide on 10 key benefits of microinverter systems.
