Frequently Asked Questions

Solar system costs vary based on size and quality. As a general guide:

• 6.6kW system: $4,500 - $7,000 (after STCs)
• 10kW system: $7,000 - $11,000 (after STCs)
• 13kW system: $9,000 - $14,000 (after STCs)

We use premium components (Jinko, Trina, Aiko panels) and all prices include installation, grid connection, and warranties. Get a free quote for an exact price tailored to your property.

Most residential solar installations are completed in 1-2 days. The typical timeline is:

• Day 1: Site assessment and quote
• Week 1-2: Permits and grid approval
• Install day: 1-2 days on-site work
• Week 2-3: Final inspections and grid connection

Total time from quote to generating power is typically 3-4 weeks.

Yes! Solar panels still generate power on cloudy days, just at reduced capacity (typically 10-25% of full output). The Sunshine Coast has excellent solar conditions year-round, averaging 6+ peak sun hours per day.

System size depends on your electricity usage and roof space:

• Small household (10-15kWh/day): 5-6.6kW system
• Medium household (20-30kWh/day): 8-10kW system
• Large household (40+kWh/day): 13kW+ system

We'll analyze your bills and roof to recommend the optimal size.

Battery system costs vary based on capacity and brand. As a general guide:

• Small system (7-10kWh): $8,000 - $12,000 (after STCs)
• Medium system (15-17kWh): $14,000 - $20,000 (after STCs)
• Large system (23-25kWh): $20,000 - $29,000 (after STCs)

We offer both GoodWe (excellent value) and Sigenergy (premium) battery systems. All prices include installation, hybrid inverter, monitoring system, and comprehensive warranties. STC rebates (up to $15,000) are already deducted. Get a free quote for an exact price tailored to your energy needs.

Yes! Battery storage delivers excellent value with both immediate and long-term benefits:

• STC rebates reduce upfront cost by $1,500-$3,000
• Save 70-90% on electricity bills
• Backup power during blackouts
• Energy independence from the grid
• Future-proof against rising power prices
• Maximize solar value by storing energy instead of exporting at low rates

Typical payback period is 6-8 years, with batteries lasting 10-15 years.

Both are quality battery systems we trust and install. The choice depends on your budget and requirements:

GoodWe Lynx Home Series (Budget-Friendly):

• 8.3kWh per module, expandable to 50kWh+
• Proven reliability and solid performance
• 10-year warranty
• Great value for money - best for budget-conscious buyers
• AC or DC coupled options
• Ideal for standard residential installs

Sigenergy SigenStor (Premium Option):

• 7.8kWh per module, highly modular (up to 62kWh)
• Advanced AI energy management system
• 15-year warranty (5 years longer than GoodWe)
• Sleek, compact design
• Superior monitoring and smart features
• Better for complex setups or those wanting cutting-edge tech
• Higher upfront cost, but longer warranty period

Our recommendation: If you're on a budget and want reliable performance, GoodWe is excellent value. If you want the latest technology, longer warranty, and don't mind paying a premium, Sigenergy is the better choice. We'll help you decide based on your specific needs during your free consultation.

Yes! Most solar systems can be upgraded to include battery storage. In most cases, we'll remove your existing inverter and install a modern all-in-one hybrid inverter with integrated battery storage.

Why replace the inverter?

• All-in-one systems are more efficient (DC-coupled)
• Better integration between solar and battery
• Cleaner installation with less equipment
• Advanced monitoring and energy management
• Often more cost-effective than AC-coupled retrofit

We'll assess your existing solar panels and design the best battery upgrade solution for your home. Your panels stay in place - we just upgrade the inverter and add batteries.

Current Queensland solar incentives include:

• Small-scale Technology Certificates (STCs): Federal rebate worth $1,500-$3,500 depending on system size (already included in our quotes)
• Feed-in Tariff: Get paid 6-8c/kWh for excess solar exported to the grid

All quotes include available rebates - we handle the paperwork for you.

Yes! Battery storage systems are eligible for Small-scale Technology Certificates (STCs) under the federal renewable energy scheme.

Battery STC rebate details (until May 1, 2026):

• Eligible capacity: Up to 50kWh (batteries installed before May 1, 2026)
• Available for new battery installations (with or without solar)
• Rebate value varies based on battery capacity and location zone
• Rebate value: Up to $15,000 for maximum eligible capacity
• Already deducted from our battery quotes - no separate application needed
• We create and assign the certificates on your behalf

Important: The 50kWh eligibility cap may change after May 1, 2026. Contact us for the latest information and to lock in your rebate before any policy changes.

The maximum inverter capacity depends on your local network's hosting capacity. Energex guidelines are:

• Single-phase connection: Maximum 5kW inverter (can have more solar panels)
• Three-phase connection: Maximum 15kW inverter per phase (up to 30kW total with export limiting)
• Export limiting: Allows larger systems with controlled grid export

Check your property's capacity: Use Energex's Network Capacity Map to see what size system your street can support. We can also check this for you during your free quote.

Note: These limits may change based on your specific location and network conditions. We handle all approvals and ensure your system is compliant.

Most residential properties on the Sunshine Coast have single-phase power and work perfectly with standard solar systems. You only need a 3-phase inverter if:

• Your property has 3-phase power (check your switchboard or meter)
• You're installing a very large system (>15kW)
• You have significant 3-phase loads (large machinery, commercial equipment)

We'll assess your property during the site visit and recommend the right setup.
