Unveiling the True: Exploring Solar Battery Price with one of Brisbane's Leading Solar Installers

As one of the leading solar installers in Brisbane, I'm thrilled to share my insights on the evolving landscape of solar battery prices. In this comprehensive article, we'll delve into the current trends, explore the various battery options, and uncover the true value and return on investment in solar energy storage.

Introduction to Solar Battery Price

The adoption of solar energy has been steadily on the rise, driven by the increasing affordability of solar panels and the growing awareness of renewable energy's benefits. However, the integration of solar batteries has been a crucial next step in maximizing the efficiency and self-sufficiency of solar power systems. In this article, we'll examine the current state of solar battery prices and help you navigate the decision-making process.

Are Solar Batteries Dropping in Price?

Declining Solar Battery Prices Due to Industry Growth

In recent years, the solar battery industry has experienced a substantial decrease in prices. This decline can be primarily attributed to the rise of new mines, the establishment of automated factories, and an increase in production volumes. From 2023 to 2024, there was a notable 30% reduction in prices, and this downward trend is anticipated to persist through 2025. As a result, solar batteries are becoming increasingly affordable for both residential and commercial use, thanks to the ongoing developments in the market.

How Much Do Solar Batteries Cost?

Solar Battery and Installation Costs

  • The cost of solar batteries varies based on multiple factors, including battery capacity, brand, and installation complexity.
  • Typically, prices range from $8000 to $10,000 per kWh of storage, with variations among brands and installation difficulty.
  • Compliance with the Australian Standard AS5139 is essential, as it provides clear instructions for battery installation, ensuring adherence to safety and quality standards.

How Much is a 5kW or 6kW Solar Battery?

We strongly discourage opting for a 5kWh or 6kWh solar battery system. The size is generally inadequate for the majority of households, and the installation costs are on par with those of a 10kWh battery. Economically, it represents a less favourable choice.

How Much is a 10kW Solar Battery?

A 10kWh solar battery system is an ideal starting point for most homes, covering essential energy needs such as TV, lighting, modems, and daily living. This capacity is well-suited for initial battery storage requirements. The price range for a standard upgrade to a hybrid inverter typically falls between $8000 to $11,000, making it a cost-effective choice for residential energy storage solutions.

How Much is a 20kW Solar Battery?

A 20kWh battery system is an ideal size for meeting the energy requirements of most households, including powering TVs, lighting, modems, and daily living essentials. It can also support limited air conditioning and heating usage in certain cases. The cost of a standard upgrade to a hybrid inverter for this system typically ranges from $16,000 to $21,000, making it a cost-effective solution for residential energy storage and backup power.

Is Getting a Solar Battery Worth It?

Investing in a solar battery is gaining momentum due to the rising power prices and decreasing feed-in tariffs. With new "time of use" tariffs charging more for power during peak times, such as 4 pm to 9 pm in the evening, the business case for a battery becomes more compelling as the potential savings increase. Moreover, battery prices are dropping as efficiency gains and volumes increase, making the return on investment increasingly attractive for homeowners and businesses.

Which is the Best Battery for Solar?

When it comes to choosing the best solar battery, there are several factors to consider, including battery chemistry, capacity, efficiency, and warranty. Some of the most popular and reliable solar battery options include lithium-ion (Li-ion), lead-acid, and flow batteries. Each type has its own advantages, and the best choice will depend on your specific energy needs, budget, and preferences.

How Long Will a Solar Battery Run My House?

The runtime of a solar battery system for your house depends on several factors, including:

  • Battery Capacity: The average battery sale is 13kWh, which covers most homes with basic usage.
  • Energy Consumption Patterns: If you are a heavier user, a larger battery is advised.
  • Size of Your Solar Panel System: Larger systems can provide even longer backup power, potentially running your home for several days.

As batteries are modular, additional modules can be added in the future if your current battery is not meeting your needs.


In conclusion, the solar battery market is evolving rapidly, with prices steadily declining and making these energy storage solutions more accessible to homeowners and businesses. As one of the leading solar installer in Brisbane, I've witnessed firsthand the transformative impact that solar batteries can have on energy independence, cost savings, and environmental sustainability.
