PROBEC designs and installs solar battery systems for homes and businesses in Wollongong, helping you store excess solar energy and make greater use of your own power throughout the day and night.
If you live in Wollongong, you’ve watched energy bills climb year after year, and you’ve probably lost power more than once when a coastal storm or an escarpment weather event knocked out the grid. That combination is why more Illawarra households are adding a solar battery, storing the power their panels make by day to use through the evening and during outages.
A solar battery in Wollongong lets you keep your own daytime energy instead of exporting it cheaply, then draw on it when evening peak rates hit or the grid goes down. With the federal battery rebate now taking around 30% off the upfront cost, the move has never made more financial sense.
At PROBEC Solar, we design and install reliable battery systems Illawarra homeowners can depend on, matched to your solar panels in Wollongong and your everyday energy use.
We install battery storage across Wollongong and the surrounding area, including Fairy Meadow, Corrimal, Figtree, Dapto, Shellharbour and Port Kembla.
● Energy independence – Instead of exporting your surplus solar cheaply, you store it and use it when you actually need it.
● Backup during blackouts – Wollongong’s position between the coast and the escarpment makes it prone to storm-related outages, so backup power is more than a nice-to-have here. A battery keeps your essentials running when the Endeavour Energy network is down.
● Cost savings – Evening peak electricity rates are among the highest in NSW. Using stored solar means you sidestep those expensive tariffs.
● A sustainable choice – Every kWh you store and use is one less drawn from fossil fuels, shrinking your carbon footprint.
In short, a home battery in Wollongong gives you control, comfort and confidence in your energy future.
Whether you’re after a premium system or a cost-effective entry point, we’ll guide you to the right fit. See our full battery options.
The most common question we hear is: “How much does a solar battery cost?” There isn’t a single answer; it depends on the details.
Price varies with the storage size you choose (a smaller 5 kWh unit, a mid-range 10 kWh system, or a larger 13.5 kWh battery for higher demand), the brand, your installation requirements, and whether you’re adding to existing solar or building a new hybrid system.
Crucially, the upfront figure you see is after the federal discount. As of 2026, the Cheaper Home Batteries Program cuts roughly 30% off the cost of eligible batteries (5–100 kWh), applied straight off your quote at the point of sale – no forms, no waiting. From 1 May 2026, the discount will taper over time and be tiered for larger batteries, so installing sooner locks in a better rate. NSW households may also add a Virtual Power Plant sign-up incentive and access interest-free Home Energy Saver loans.
Over time, using your stored energy instead of buying at peak rates reduces your bills – which, alongside the rebate, is what shortens the payback period.
A home battery setup in Wollongong can be hybrid (grid-connected with backup capacity) or off-grid (for properties without reliable grid access). Both integrate with your existing solar panels. Here’s the flow:
The result: more of your solar stays in your home, and less is exported at low feed-in rates.
