A solar system can generate plenty of electricity during the day, but your home or business may continue using electricity after the sun goes down.
That is where battery storage can become worth investigating.
Oz Home Energy provides battery storage installation in Sydney for suitable homes and businesses. As a licensed NSW electrical contractor, we take an installer-led approach to battery projects, focusing on your electricity use, existing energy system, property and practical requirements.
A battery is not automatically the right solution for every property. The appropriate system depends on how you generate and use electricity, the solar system you have or plan to install, and what you want your energy system to achieve.
If you are exporting solar during the day but buying electricity at night, an energy assessment is a practical place to start.

Battery storage allows electrical energy to be stored and used at a later time.
For a property with solar, this can provide a way to store some of the electricity generated during daylight hours for potential use when solar generation decreases.
For example, your solar system may generate more electricity than your household needs in the middle of the day. Later that evening, your household may still require electricity even though the solar panels are no longer generating at the same level.
A battery can sit between these two periods by storing energy for later use.
However, battery storage is not simply about installing the largest battery possible.
The appropriate solution depends on your electricity consumption, solar generation, existing electrical infrastructure and intended use.
Oz Home Energy assesses these factors before recommending a practical battery installation.
If your solar system generates more electricity than you are using during the day, battery storage can provide a way to store some of that energy for later use.
This may be particularly relevant for properties with significant evening electricity consumption.
Your electricity requirements do not stop when the sun goes down.
A battery can provide stored energy for use during periods when your solar system is generating less electricity.
Generating electricity at your property can reduce the amount of electricity you need to purchase from the grid when your solar system is producing energy. The actual impact depends on your energy consumption, solar generation and when electricity is being used.
Your roof may provide an opportunity to generate electricity directly at your home or business. We assess the property and relevant installation requirements rather than assuming every roof is suitable for the same system.
Solar and battery storage can work together as components of a wider household or business energy system.
If you are also considering EV charging, your overall electricity requirements can be assessed together.
Household energy use can change over time. An EV, new appliances, increased air conditioning use or changes in working patterns can all affect your electricity requirements.
Battery storage may be one option worth considering as those requirements change.
Electricity costs are an important consideration for many households and businesses.
Solar can form part of a broader strategy to manage how your property generates and uses electricity.
Solar does not necessarily need to be viewed as a standalone project.
Depending on your circumstances, your future energy requirements may include battery storage or EV charging. Considering those requirements early can help you make more informed decisions about your electrical and energy setup.
For suitable properties, stored energy may reduce the amount of electricity purchased from the grid during periods when battery energy is available. Actual outcomes depend on the system and how the property uses electricity.
Solar generation occurs when sunlight is available. This can be particularly relevant for homes and businesses that use electricity during the day. Understanding when your property consumes electricity helps determine how useful solar may be for your circumstances.

This service is primarily for customers who already have solar. It may suit you if your electricity bills remain higher than expected, your household electricity consumption has increased or you are exporting more solar than you can use during the day.
It may also be appropriate if you have recently purchased an EV and want to understand how vehicle charging will interact with your solar system. Homeowners considering battery storage can also use this service to assess whether their existing solar system is suitable for an upgrade.
Businesses with existing solar may also enquire about suitable commercial solar and battery upgrades. If you do not currently have solar, our Solar Installation service is the more appropriate starting point.

We start by understanding why you are considering battery storage.
You may want to use more of your existing solar, reduce grid reliance or prepare for changing electricity requirements.

A recent electricity bill can provide useful information about your electricity consumption. You can upload your bill as part of an energy-savings assessment.

If you already have solar, we consider the existing system and its relevant electrical requirements.
This helps establish what battery options may be appropriate.

Battery capacity and configuration should relate to the property's electricity consumption, solar generation and intended use.
We consider these requirements before recommending a solution.

We explain the proposed battery installation in straightforward terms, including relevant electrical and installation considerations.

Once the requirements are understood, we provide a quote based on the actual project rather than a generic battery price.

Once approved, the battery system is installed as part of the agreed electrical scope. Safety and reliable workmanship remain central to the installation.

The completed system is checked and relevant information about its operation is explained.

Sydney households can have very different electricity requirements.
Some homes use most of their electricity during the day. Others consume much more electricity in the evening.
Some households have existing solar. Others are planning a new system.
Some have EVs or other significant electrical loads.
Battery storage should therefore be assessed against your actual circumstances rather than treated as a standard product purchase.
If your situation is:
“I export solar during the day but buy power back at night.”
an energy assessment can help determine whether battery storage is worth considering.

Businesses may have different energy patterns from residential properties.
Operating hours, equipment, solar generation and electricity demand can influence whether battery storage is suitable.
Oz Home Energy can assess suitable commercial battery projects in Sydney and may also consider appropriate solar, battery and commercial electrical projects across wider NSW.
For larger or more complex projects:
If you have solar, battery storage and an EV charger, these systems should be considered as part of your broader energy requirements.
For example, your household may generate solar during the day, store some energy in the battery and charge the EV at another time.
The practical outcome depends on the property's electricity use and equipment.

Battery installation pricing varies according to the individual project.
Factors can include:
Battery capacity
Battery equipment
Existing solar system
New solar system requirements
Electrical infrastructure
Installation location
Property access
Additional electrical work
System configuration
Because of these variables, a generic battery price may not accurately represent your project.

About Battery Storage
A battery stores electrical energy so it can be used later.
For a solar property, this can mean storing some electricity generated during daylight hours and using that stored energy when solar generation decreases.
The actual operation depends on the system configuration and how the property uses electricity.
Not necessarily, but battery storage is commonly considered as part of a solar energy system.
If you already have solar, we can assess the existing system.
If you are planning new solar, battery storage can be considered during the solar planning process.
Potentially.
Existing solar systems vary in age, configuration and equipment.
Your current system and electrical infrastructure need to be assessed before determining the appropriate battery installation.
Potentially.
If your solar system generates more electricity than your property consumes during the day, a battery can provide a way to store some of that energy for later use.
Whether this makes sense for your property depends on your electricity consumption and solar generation.
No specific savings result should be guaranteed.
Your electricity consumption, solar generation, battery capacity, usage patterns and grid electricity requirements all influence your electricity costs.
Oz Home Energy does not publish unsupported savings guarantees.
The appropriate size depends on your electricity use, solar generation and intended purpose.
A larger battery is not automatically the best option.
An energy assessment can help establish what capacity may be appropriate for your circumstances.
