Solar panels are great for daytime power in Wollongong, but what about nights or blackouts? A solar battery transforms your system into a 24/7 energy solution, crucial as NSW targets 82% renewables by 2030.

Why Add a Battery?

Batteries store your excess solar energy, offering significant advantages:

• Use Your Own Solar, Day & Night: Store daytime solar to power your home in the evening, drastically cutting reliance on expensive grid electricity. This is known as maximising “self-consumption.”
• Blackout Protection: With the right setup, a battery can keep essential appliances (lights, fridge, modem) running during grid outages – a huge benefit.
• Greater Independence: Reduce your exposure to rising electricity prices and gain more control over your energy supply.
• Support the Grid: Some programs (Virtual Power Plants) allow you to earn by letting the grid use your stored energy during peak demand.

Key Battery Considerations:

• Capacity (kWh): How much energy it stores. Your installer will help size this based on your usage and goals.
• Power Rating (kW): How much power it can deliver at once, determining how many appliances can run simultaneously.
• Depth of Discharge (DoD) & Lifespan: Look for high DoD (how much capacity you can safely use) and a long lifespan (often 10+ years warranty, measured in cycles). Lithium Iron Phosphate (LFP) chemistry is popular for safety and longevity.
• Compatibility: Ensure it works with your solar inverter (hybrid inverters are ideal for new systems; AC-coupling can work for existing ones).
• Safety & Installation: Always use reputable brands meeting Australian standards, installed by a CEC-accredited professional in a suitable, cool, and dry location.

Smart Energy Storage

Modern batteries often come with smart controls to optimise charging and discharging for maximum savings.

Is a Battery Your Next Step?

While an investment, a battery significantly enhances your solar benefits. The STC scheme helps reduce overall solar system costs, making batteries an increasingly attractive option for Wollongong households seeking energy security.
