15kW Solar System Price
How much will a 15kW solar system cost?
The cost of a 15kW solar system depends on a few factors, like where you live, your roof design, and your energy needs. Typically, a high-quality system will cost between $10,000 and $18,000 after applying government incentives and rebates.
This price includes professional installation and top-notch solar components.
What's the 15kW System Cost?
A good quality 15kW solar system will usually cost in the range of $10,000 to $18,000.
A 15kW system is a smart long-term investment. Thanks to energy savings and government rebates, you’ll likely see the system pay for itself within 3 to 5 years.
While cheaper options are out there, investing in high-quality solar panels and inverters ensures your system will run more efficiently and last longer, saving you from headaches like frequent repairs or replacements down the track.
Do I Need Battery Backup?
Adding a battery backup to your 15kW solar system comes with plenty of perks. A battery allows you to store the extra energy you generate during the day so you can use it at night or during power outages.
This helps you rely even less on the grid. However, the cost of battery storage depends on your specific energy usage and budget, so it’s worth weighing the pros and cons for your situation.
15kW Solar System with Battery Backup
A standard solar system can only generate power during daylight hours.
A standard solar system can only generate power during daylight hours. Adding battery backup means you can store power for night-time use. This allows you to use your stored electricity instead of paying peak rates. Battery backup also keeps you powered up if you experience frequent power outages.
Battery Backup Products
For the best performance, we suggest Tesla Powerwall or Sungrow batteries. These are known for their safety, fast recharge times, and higher storage capacity compared to older battery types.
Plus, they work great even in extreme temperatures, making them perfect for Australian homes and businesses.
Lithium ion batteries offer many benefits over other battery types including:
- Better safety
- Faster recharge
- Greater storage capacity
- Better performance at temperature extremes
What's the Battery Backup Cost?
While the upfront investment might seem steep, over time it pays for itself by allowing you to store energy and further cut your power bills, all while giving you peace of mind during power outages.

15kW Solar System - Output Per Day
On average, a 15kW solar system will generate between 60 and 65 kWh of electricity per day.
The actual amount depends on factors like how your panels are oriented, how much sunlight your location gets, and any shading that might affect your roof. This is more than enough to meet the energy needs of large homes or small commercial properties.
A range of factors may influence the total power production from a system including:
- Number of peak sunlight hours
- Shade (even small amounts)
- Temperature extremes
- Panel orientation
