Frequently Asked Questions

-
The cost of a solar battery in South Australia typically ranges from $10,000 to $16,000 depending on the capacity and brand, such as the Tesla Powerwall 3 or Sungrow. While the upfront investment is significant, we focus on calculating your actual ROI based on your specific energy usage and the current SA export limits to ensure it’s a viable financial move for your home.
-
It depends on the age and brand. If you have a premium unit like a Fronius or Sungrow that is just out of warranty, a repair is often a cost-effective way to get another 5–10 years of life. However, for "generic" budget inverters that have failed, we usually recommend a replacement with a high-quality unit to avoid throwing good money after bad.
-
Yes. We specialise in "battery retrofitting." Even if your system was installed by another company years ago, we can integrate modern AC-coupled batteries like the Tesla Powerwall 3. This allows you to store your excess daytime generation rather than exporting it to the grid for a minimal credit.
-
While the state-based battery subsidy has ended, the Federal "Small-scale Technology Certificates" (STCs) still provide a significant discount on the total cost of a new system or upgrade. We handle all the paperwork for you, ensuring the rebate is applied as a point-of-sale discount.
-
Most premium batteries we install, including the Tesla Powerwall 3, are rated for outdoor installation. However, South Australia's extreme UV can degrade hardware over time. We always aim to install units in a shaded area or use protective shrouding to maximise the lifespan of the internal cells.
-
Adelaide’s climate is brutal on electronics and silicon. We’ve seen hundreds of "budget" systems fail after just 4 or 5 years. We recommend trusted brands because they are engineered to handle high-ambient temperatures and provide a significantly higher return on investment over 25 years.
-
Absolutely. A large portion of our work involves "orphan" systems. As local solar electricians, we can perform a full diagnostic audit, identify why your system isn't performing, and provide a certified repair or component replacement to get your investment back on track.
-
In South Australia’s dusty environment, we recommend a professional service and clean every 18 to 24 months. This isn't just about rinsing off dust; it involves an electrical safety check and an inverter health diagnostic to ensure you aren't losing 15–20% of your production to grime or faulty wiring.
-
Standard solar systems will shut down during a blackout for safety reasons (to protect workers on the lines). If you want power during an outage, you need a battery with "backup" or "off-grid" functionality. We can design a system that keeps your "essential loads"—like your fridge, lights, and Wi-Fi—running when the grid goes down.
-
This is usually due to "self-consumption" timing. If you are generating power during the day while no one is home, that energy is exported for a low credit while you pay full price for power at night. We provide system audits to help you shift your appliance usage or discuss battery storage to capture that lost value.
