Common Questions Answered

💰 How much does it actually cost?

After government rebates (typically $5,900-$23,500 depending on state), a typical residential system costs $5,000-$15,000. Most homeowners see this paid back through energy savings in 3-5 years, then enjoy 20+ years of free electricity.

⏱️ How long does installation take?

Typical installation: 1-3 days once approved. Approval process (council, grid connection): 2-6 weeks. Total timeline from consultation to switch-on: 4-8 weeks on average.

🏠 Will it damage my roof?

No. Professional installers use specialized mounting systems that preserve waterproofing. Tile roofs: tile hooks slide under tiles. Metal roofs: clamps attach without penetration. All installations include weatherproofing and come with workmanship warranty.

🌧️ What happens when it's cloudy or raining?

Panels still generate 10-25% output on cloudy days. You remain connected to the grid, so when solar isn't producing enough, you draw from the grid. With battery storage, you can store sunny-day excess for use during rain/night.

⚡ What if I use more power than the system generates?

Grid-tied systems automatically draw from the grid when solar isn't enough. You only pay for the difference. Most households use 50-80% solar, 20-50% grid, resulting in 60-80% bill reduction.

🔧 What maintenance is required?

Minimal. Clean panels 2-4 times per year (more if coastal/dusty area). Annual electrical inspection recommended. Inverter may need replacement after 10-15 years ($1,500-$3,000). Panels last 25-30 years with proper care.

💡 Can I go completely off-grid?

Yes, but requires battery storage (adds $10,000-$30,000 to system cost). Most homeowners stay grid-connected for reliability and feed-in tariff benefits. Off-grid makes sense for remote properties or those seeking complete energy independence.

📄 What about warranties?

Standard warranties: Panels 25-year performance (80%+ output guaranteed), Inverter 5-10 years, Installation workmanship 5-10 years. All included. Extended warranties available.

🏦 Can I finance the system?

Yes. Options include: Solar loans (green loans with low rates), home equity, government schemes, and some installers offer payment plans. Many homeowners finance and still save money from day one because loan payment < electricity bill savings.

🏘️ What if I'm renting?

You'll need landlord permission. Some landlords approve because it increases property value. Portable solar options exist for renters (balcony panels, plug-and-play systems).
