Frequently Asked Questions
Frequently Asked Questions – Residential Solar
📘 What is the typical cost of a home solar system?
6.6kW solar system usually ranges between $5,000 and $9,000 after applicable government rebates. The final price varies based on panel quality and installer fees.
⚡ Will my solar panels generate power during a blackout?
Standard grid-connected systems automatically shut off during blackouts for safety. Solar panels only provide power during outages if paired with a battery backup system.
🔁 How do feed-in tariffs work for solar energy?
Feed-in tariffs reward homeowners for exporting surplus solar electricity back to the grid. Rates differ across states and energy retailers, typically between 5 and 15 cents per kilowatt-hour.
💡 Is investing in solar panels worthwhile in Australia?
Absolutely. Thanks to Australia’s plentiful sunshine, rising electricity prices, and attractive government incentives, most homeowners recover their investment within 3 to 6 years and enjoy substantial savings for decades thereafter.
🌳 Can I install solar if my roof has shading issues?
Shading can reduce system efficiency, but technologies like optimisers and micro-inverters can help mitigate this. For significant shading, ground-mounted systems or community solar options might be a better fit.
📐 How do I determine the right solar system size for my home?
System size should align with your household’s energy consumption. A 6.6kW system suits most families, while larger households or high energy users might consider systems above 10kW.
🔋 Are solar batteries a good investment for homes?
Solar batteries store excess energy for use after sunset, reducing reliance on the grid. While prices are decreasing, payback periods typically range from 7 to 12 years.
🧼 Is regular cleaning necessary for solar panels?
Periodic cleaning every 6 to 12 months helps maintain peak performance, especially in dusty areas. Rain can help, but professional cleaning maximises energy output.
🏛️ What government rebates are available for residential solar?
Homeowners can benefit from Small-scale Technology Certificates (STCs) providing upfront discounts. Some states, like Victoria, offer additional rebates and interest-free loans.
⏳ What is the expected lifespan of solar panels?
Most solar panels last 25 years or more, with warranties usually covering at least 20 years of guaranteed performance.
Frequently Asked Questions – Commercial & Industrial Solar
🏭 Is it possible for solar panels to power an entire business or industrial facility?
Yes, many facilities can run primarily on solar, depending on their energy needs and roof space. For operations with high demand, solar is often used alongside the grid, and adding battery storage can further increase energy independence.
📊 What kind of return can my business expect from a commercial solar system?
Most businesses see a return on investment within 3 to 5 years. With reduced energy bills and low maintenance costs, solar systems continue delivering savings for 25 years or more.
💰 What financing options are available for commercial solar?
There are several ways to fund a system, including solar leases, green loans, and Power Purchase Agreements (PPAs). These options allow businesses to install solar with little to no upfront cost and spread payments over time.
⚖️ How does a Power Purchase Agreement (PPA) work for businesses?
A PPA lets your business install solar panels at no upfront cost. Instead of owning the system, you purchase the energy it produces at a lower, fixed rate — often cheaper than your current electricity rate — saving you money from day one.
🧾 What are the government incentives for commercial solar?
Eligible businesses can take advantage of Small-scale Technology Certificates (STCs) for systems under 100kW, or Large-scale Generation Certificates (LGCs) for larger systems. Many also benefit from tax deductions, such as the Instant Asset Write-Off, and some states offer additional grants or rebates.
🛠️ Do commercial solar panels require much upkeep?
Not at all. Quality commercial panels are built to last 25 to 30 years. Apart from occasional cleaning and annual inspections, maintenance is minimal, and performance remains high over the system’s lifespan.
🔌 Can I sell excess solar energy back to the grid?
Yes. Businesses that generate more electricity than they use can feed that energy back into the grid. In return, your energy retailer may offer a feed-in tariff that helps reduce your overall electricity bill.
🚀 What are the main benefits of solar for my business?
Solar helps lower energy bills, reduce carbon footprint, and increase energy independence. Plus, you’ll be future-proofing your business against rising power costs — all while taking advantage of generous government support and possible tax savings.
Let’s build that future together.
