Vista Electrical performs a thorough site assessment to provide an accurate free quote reflecting your specific roof conditions.
System Size Requirements
The solar PV system size (kW) needed depends on your electricity consumption, budget, and available roof space. We analyse your energy bills and lifestyle to recommend an appropriately sized system, ensuring you generate the maximum amount of power needed without overinvesting. See average costs by system size.
Government Incentives and Solar Rebates in Perth
Generous government incentives and solar rebates significantly reduce the upfront cost of going solar with Vista Electrical Controls in Western Australia.
Federal STC Program (Solar Rebate)
The Small scale Technology Certificate (STC) program provides a substantial point-of-sale discount on your solar system. The value depends on system size and location (Perth is in Zone 3). These small technology certificates are a major factor in reducing solar panels cost.
- For a typical 6.6kW system installed in Perth in 2025, the STC rebate usually reduces the total cost by $2,500 $3,000.
- Vista Electrical handles all the paperwork and applies this discount directly to your invoice, making the process seamless for you.
Western Australia State Incentives
While WA doesn’t offer a direct state rebate like some others, homeowners benefit from:
- WA Distributed Energy Buyback Scheme(DEBS): This scheme, managed by Western Power and Synergy, pays you for excess electricity your solar power system exports back to the electricity grid. Rates vary depending on the time of day electricity is exported (higher rates during peak evening hours). This provides ongoing bill credits and improves savings.
- Battery Storage Grants/Subsidies: Occasionally, the WA government offers incentives or solar battery rebates for adding home batteries. Vista Electrical stays current on these programs and can advise if you qualify.
We ensure you leverage all available incentives to maximise your solar investment’s value.
