Frequently Asked Questions
​
Got questions about solar or battery installation?
Here are some of the most common queries we receive at Battery Solar World — all answered in one place.
1. How much does a solar system cost?
​
The cost depends on the size of your system, roof type, and energy usage. On average, a 6.6 kW system for a standard home can range between $4,000–$8,000 after government rebates (STCs). For larger homes or battery packages, we’ll provide a customised quote based on your needs.
​
Tip: Request a free consultation so we can design the right system for your property.
2. What rebates or incentives are available?
​
The main national incentive is the Small-scale Technology Certificates (STCs), which reduce the upfront cost of your solar system. In some states, additional battery rebates or finance options may be available. We handle the entire rebate process for you — no paperwork hassle!
3. Should I add a battery to my solar system?
​​​
A solar battery stores excess solar energy for use at night or during blackouts. It helps reduce your grid dependency and electricity bills. While it’s not essential, batteries are becoming more affordable and can significantly increase your energy independence.
​
​4. How long does installation take?
​
Most standard residential installations take 1 to 2 days, depending on roof size, access, and weather. Larger or commercial systems may take a bit longer. Our team always schedules the work to minimise disruption to your routine.
​
5. Do solar panels need regular maintenance?
​
Solar systems are mostly low-maintenance, but cleaning and inspection every 12–18 months helps maintain efficiency and safety. Our technicians provide professional cleaning, system checks, and performance testing to ensure your system runs at peak output.
6. How long do solar panels and inverters last?
​​​​​
Quality solar panels typically last 25 years or more, and most inverters last 10–15 years. At Battery Solar World, we only install CEC-approved components from trusted brands, all backed by solid manufacturer and installation warranties.
​
7. What happens if my solar system stops working?
​
If your system underperforms or shuts down, contact us right away. We offer fast service calls, diagnostics, and repairs. Our CEC-accredited technicians can detect faults, replace parts, and get your system running smoothly again.
