- Solar Upgrades for Brisbane Properties
Solar Upgrades Designed Around Your Existing System
Sunpac Solar upgrades existing systems for Brisbane homes and businesses whose usage, equipment or switchboard no longer match the original installation. A solar panel upgrade adds capacity to meet higher electricity use.
We upgrade solar panels by adding to your existing array, or by replacing the full system when the equipment is ageing or faulty.
Each upgrade starts with a check of your current panels, inverter and switchboard, so new equipment suits what is on your roof.
- Why Upgrade Your Solar
Get More from the Solar System You Already Have
An upgrade can match a system to higher usage, replace a failing inverter or add storage. Here are the common reasons Brisbane customers upgrade an existing solar system.
Match Higher Usage
Add panels when an EV, new appliances or more people raise usage.
Replace an Ageing Inverter
Replace a faulty or ageing inverter to restore output and monitoring access.
Add Battery Storage
Add a battery to store surplus solar and use it after sunset.
Update Your Meter Box
Update a meter box to meet current standards and add circuit space.

Which Solar Upgrade Does Your System Need?
Choose the upgrade that matches your system’s age, inverter capacity and usage.
| Upgrade | When It Suits | What It Involves |
|---|---|---|
| Add Panels | Higher usage and an inverter with spare capacity | New panels connected to the existing inverter, with network approval where needed |
| Upgrade Solar Inverter | A failed, ageing or undersized inverter | Replace the inverter, and add panels or a battery if the new unit allows |
| Add a Battery | Surplus solar exported during the day | A hybrid or AC-coupled battery connected to your system and switchboard |
| Meter Box Upgrade | An older, full or non-compliant switchboard | New circuit protection or a new switchboard to suit the added equipment |
| Full System Replacement | Ageing panels and inverter | New panels and inverter installed together as one system |

- Government Solar Incentives & FinancE
Solar Upgrade Incentives and Finance
STC discounts can apply to added panels or a full system replacement. We check your system against current rules and apply any eligible discount to your quote.
Replacing some panels or an inverter alone does not create STCs, so the type of upgrade affects the discount.
Government Solar Incentives
Eligible upgrades may receive federal STCs, applied as a discount on your quote.
Battery Rebates
Eligible batteries may receive a federal discount through the Cheaper Home Batteries Program.
Flexible Finance Options
Finance options may be available through approved lenders, subject to credit approval.
Simple Application Process
We prepare the STC and network approval paperwork, so you have less to arrange.

Frequently Asked Questions
Answers to common questions about commercial solar in Brisbane, from system size and pricing to incentives and installation time.
How much does commercial solar cost?
Cost depends on system size, products, roof type, switchboard condition and STC eligibility. We provide a free quote after a site assessment and a review of your electricity bills.
What is the payback period?
Payback depends on system size, electricity usage, tariff and incentives. Your proposal includes an estimated payback for your site.
What size system does my business need?
Size depends on your usage, roof space and operating hours. We assess your site and recommend a size. Larger systems need a more detailed network application.
Can you install without shutting down my business?
We plan installation around your trading hours. Some work, such as the switchboard connection, may need a short planned outage that we schedule with you.
