How do I know if my home is suitable for solar?

If you have a roof with good sun exposure (ideally north-facing), minimal shading and use a fair amount of electricity during the day, solar is likely a great fit. We’ll assess your property to confirm suitability.

A solar battery stores the excess energy your panels generate during the day so you can use it at night or during power outages. It’s ideal if you want energy independence, more savings, or backup power.

Prices vary based on system size and brands chosen. As a guide, a 6.6kW system without battery starts around $4,000–$6,000 (after rebates), while adding a battery like Tesla Powerwall may bring the total to $12,000–$15,000. We’ll tailor a quote to your needs.

Yes! Most systems are battery-ready and we can retrofit a compatible battery to your current setup after assessing your inverter and panel configuration.

Yes, grid regulations can affect how your solar system exports energy. In Geelong, Melbourne, & surrounding regions, systems may include features like the Emergency Backstop, which can limit exports during rare grid instability events. This does not stop your system from powering your home, it only controls excess energy sent to the grid. Current policies do not charge for solar exports, but regulations may evolve over time.

Yes. Modern solar batteries are designed with advanced safety features, meeting strict Australian standards. Quality systems use stable battery chemistries like lithium iron phosphate (LiFePO4), reducing safety risks. When installed by accredited professionals, solar battery storage systems are safe and reliable for everyday use.

Solar battery rebates are available through Federal programs like STCs and additional Victorian incentives. The rebate amount depends on your system size and usable battery capacity. While larger systems may attract higher rebates, it’s more important to size your system based on your actual energy needs.

Current rebate programs are expected to gradually reduce over time, especially beyond 2026. In many cases, combining solar with a battery still improves savings through self-consumption. Speaking with a professional ensures you get the right solar battery storage solution and maximise available incentives.

Most solar batteries last 10–15 years, with warranties typically covering around 10 years. Leading brands like Tesla, Sungrow, and Sigenergy are built for long-term performance and reliability. The actual lifespan depends on usage, system design, and how well the battery is maintained. Over time, capacity may gradually reduce, which is normal for all battery storage systems.
