Can I add a battery to my existing solar system?

Potentially, The answer depends on your existing solar system, electrical infrastructure, equipment and energy requirements. An assessment is needed to determine whether battery storage can be appropriately integrated with your existing setup.

Do I need to replace my existing solar system?

Not necessarily. An existing system may still be suitable for continued use or upgrading. The right approach depends on its configuration, condition, capacity and how your electricity requirements have changed. We assess the existing system before recommending an approach.

My solar works during the day but I still have high bills at night. Can you help?

Yes. This is one of the situations where a solar and battery upgrade assessment can be useful. If your solar generates electricity during the day but your property consumes significant electricity after sunset, battery storage may be one option worth investigating.

Can I upgrade an older solar system?

Potentially. Older systems can vary significantly, so the system needs to be assessed before determining whether an upgrade is appropriate. Depending on the circumstances, the right approach could involve additional equipment, battery storage, electrical work or replacement of some components.

Can you assess my existing solar system?

Yes. Oz Home Energy can assess suitable existing solar systems as part of a solar and battery upgrade enquiry.

How do I know if a battery is suitable for my existing solar?

Your electricity consumption and solar generation are important factors. If you export significant solar during the day and consume electricity later in the evening, battery storage may be worth investigating. A recent electricity bill can provide useful information for an assessment.

Will a battery eliminate my electricity bill?

No specific result should be assumed. The outcome depends on your solar generation, electricity consumption, battery capacity, usage patterns and grid electricity requirements. Oz Home Energy does not publish unsupported savings guarantees.

What size battery do I need?

Battery capacity should be considered in relation to your energy use and existing solar system. A larger battery is not automatically the right solution. The appropriate capacity needs to be assessed based on your circumstances.

Can I add an EV charger to my existing solar and battery system?

Potentially. An EV adds another electricity load to the property, so the existing solar, battery and electrical infrastructure should be considered together. Oz Home Energy can assess EV charger requirements as part of a broader energy upgrade.

How much does a solar and battery upgrade cost?

There is no single price because every existing solar system and property is different. Costs can depend on the existing equipment, battery requirements, electrical work, installation complexity and proposed upgrade. Oz Home Energy provides project-specific quotes following assessment.

Do you provide free upgrade quotes?

Yes. Free quotes are available for suitable projects.

Can I upload my electricity bill?

Yes. Uploading a recent electricity bill is one of the easiest ways to provide useful information for an initial solar or battery savings assessment.

What if I am not sure whether I need an upgrade?

That is exactly why an assessment can be useful. You do not need to decide whether you need a battery, new solar panels or another upgrade before contacting us. Tell us what is happening with your electricity use and what you want to achieve.

What Are Commercial Electrical Services?

Commercial electrical services cover electrical installation, upgrades and related work required by businesses and commercial properties.

The requirements can vary significantly depending on the property, business operations, equipment, existing electrical infrastructure and scope of the project.

A small business premises may require relatively straightforward electrical work, while a larger commercial property may require broader electrical infrastructure, energy upgrades or project coordination.

Oz Home Energy takes a practical approach to assessing suitable commercial projects.

We first seek to understand:

What the property is used for
What electrical work is required
Existing electrical infrastructure
Current and future energy requirements
Whether solar, battery or EV charging is involved
Project location and scope

This allows us to determine the appropriate next step before work is undertaken.

When Does a Business Need Commercial Electrical Work?

Your Business Is Expanding

Business growth can mean additional equipment, work areas or electrical loads. If your electrical requirements have changed, your existing infrastructure may need to be assessed.

You Are Installing New Equipment

New commercial equipment can introduce additional electrical requirements. The appropriate electrical connection and infrastructure depend on the equipment and property.

Reduce Reliance on Grid

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.

Make Better Use of Your

Roof

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.

You Are Upgrading Your Energy System

Solar, battery storage and EV charging can all change how a commercial property generates or consumes electricity. These systems should be considered alongside the existing electrical infrastructure.

You Are Planning an EV Fleet

Businesses introducing electric vehicles may require charging infrastructure. Multiple chargers can create significant electrical requirements, making early project assessment important.

Take Greater Control of Energy Costs

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.

Build Towards a Broader Energy System

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.

Your Switchboard Is No Longer Suitable

A switchboard may need to be assessed when a property adds significant new electrical loads. This does not automatically mean an upgrade is required, but the existing infrastructure should be considered.

Generate Electricity During Daylight Hours

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.
