Our Solar Batteries
Solar batteries are revolutionising home solar power systems. Battery storage enables more families to use renewable energy to power their day-to-day lives. The result is greater self-consumption of solar generation and reduced energy costs. From 2.5kWh to 15kWh, any home situation can be covered.
With 13.5 kWh of stored energy, the Tesla Powerwall 3 is ready to support your everyday needs.
The Tesla Powerwall 2 reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining.
The IQ Battery 5P boasts remarkable potency, delivering a peak power of 7.68 kW and a continuous power output of 3.84 kW.
A sonnenBatterie will allow you to cover around 80% of your yearly energy requirement with self-produced and clean energy.

Michael Ryan6 August 2024Trustindex verifies that the original source of the review is Google. Like many, I did a fair bit of research before selecting HCB Solar (having had either no confidence or no satisfactory response from four previous companies). From my first phone call to the installation (yesterday) and to our first full day with the system, I have nothing but praise. From order to installatioin was only 2 weeks, the pre-installation inspection was excellent in providing both information and advice, the installers arrived on time, were courteous and efficient, gave a great run through of the system and how to monitor production and consumption and left the place clean and tidy. I would happily recommend them and would certainly use them again for future expansion of the system. ***** Now some years down the track I would still recommend them. We had one small part fail a few years ago. One phone call, no problem, fixed in a matter of days. I'm only sorry we didn't install a battery at the same time as the panels! Shane L5 August 2024Trustindex verifies that the original source of the review is Google. Very professional solar business. Did a lot of online research & reading reviews before deciding on HCB.

Is a Solar Battery worth the investment?
One common concern we hear from people is whether investing in a battery is worth it. Some homeowners hesitate because they’re unsure about the upfront costs or whether the benefits justify the investment. When customers express these concerns, we often encourage them to consider their energy consumption patterns and the potential long-term savings.
Frequently asked questions
Unfortunately, this is not a simple question to answer, it requires a little math and so we need to know the size of your solar system and the amount of electricity you consume.
The usable storage capacity of a solar battery is the amount of energy that can be stored or discharged by the battery. This storage capacity can vary depending on the kW size of the battery you get to go with your solar system, i.e. a 10kW battery vs a 15kW battery.
A solar battery can usually hold it’s charge for up to 20 years, but this can vary widely depending on a number of factors, including frequency of use and maintenance for example.
Once your solar batteries are fully charged, any additional solar power that is generated will be redirected and sold to the grid.
Solar batteries typically use one of three chemical compositions: lead acid, lithium ion, and saltwater. However, lithium ion batteries are the most common and best option for a solar panel system, though other battery types can be more affordable.
How much a solar battery will cost will depend on how big a battery you want and whether you are buying the battery on its own or with an inverter/charger. But could cost between $8,000-$15,000.
Some of the bigger batteries we have available include the Tesla Powerwall 2 with a 13.5kWh capacity and the sonnenBatterie with up to a 15kWh capacity. Contact us for more information on battery capacity.
With solar monitoring technology it is unlikely you will overcharge your solar battery. These intelligent solar system technologies monitor the systems generation, your consumption and redirects additional energy that’s generated to the grid.
