Genr8 Energy — Solar & Energy in Devonport

A 6.6kW system (the most popular size) costs $5,000–$9,000 after the STC government rebate. Prices vary by state, brand, and installer. A 10kW system costs $8,000–$14,000. Always compare quotes from at least 3 Clean Energy Council (CEC) accredited installers and check what the rebate amount is for your postcode.

Most Australian homes use 15–25kWh per day. A 6.6kW system produces 24–30kWh/day on average. For households with high daytime usage (retirees, home offices, EVs), a 10kW system maximises self-consumption. Add a battery to capture surplus energy for evening use. An energy audit helps determine the right size.

Yes, for most Australian homeowners. Payback periods are typically 3–6 years, with systems lasting 25–30 years. Feed-in tariffs (what your retailer pays for surplus energy exported) have dropped to 5–12 cents/kWh in most states, so maximising self-consumption is key. A north-facing roof with minimal shading gives the best returns.

The federal Small-scale Technology Certificate (STC) scheme provides an upfront rebate reducing system costs by $2,500–$4,500 for typical residential systems. The rebate amount depends on your location (zone), system size, and current STC market price. The rebate reduces slightly each year until 2031. State-specific rebates (VIC Solar Homes Program, etc.) provide additional savings in some states.

Batteries (typically $10,000–$16,000 installed for 10–13kWh) extend your energy independence and are most valuable if your retailer offers low feed-in tariffs, you have high evening usage, or you experience frequent power outages. Payback on batteries alone is currently 8–12 years. Virtual Power Plants (VPPs) can improve returns.
