Solar & Battery Savings in Tasmania, Australia Costs, Savings & Quotes
Design solar and battery systems for Tasmania using Photonik's professional design platform. While Tasmania is Australia's most southerly state, it still receives excellent solar generation throughout the year. With some of Australia's highest electricity prices, Tasmanian homeowners can achieve strong financial returns from rooftop solar, particularly when paired with battery storage.
Solar Design Tasmania
Energy Usage
Residential energy usage in Tasmania typically ranges from 15-30 kWh daily, with 25 kWh being common for a standard household. If your usage is above 25 kWh per day, switching to efficient appliances, smart hot water, or a pool pump timer can bring you closer to efficient-home levels.
It's worth reducing your energy usage before going solar, as this can decrease the system size you need and improve payback. Focus on better insulation and energy efficient appliances.
Typical energy usage per person per day in Tasmania:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Based on 25 kWh daily usage, a 6.6kW system is a good starting point for Tasmania — though many homeowners choose to install slightly more. A system in the 9.9kW to 13.2kW range also gives you headroom if your energy needs grow — from a new EV, heat pump, or home office.
Expect around 40.2 kWh daily from a 9.9 kW system in Tasmania, with production varying from 2.89 kWh/kW/day in June to 4.75 kWh/kW/day in February.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Tasmania
Solar Battery Sizing
A solar-only system in Tasmania covers about 50% of your energy needs during daylight hours, but without a battery the 50% you use at night still comes from the grid. The jump from 50% to 86% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.
The gap between June and February production affects how much work your battery does season to season — the full Photonik tool models this for your specific situation.

Solar & Battery System Cost Tasmania
Understanding Solar & Battery System Costs
Solar systems in Tasmania are priced around $11,137 for a 9.9 kW installation, rising to approximately $17,278 when including a 10 kWh battery. After the 6.0-year payback period, your solar system continues producing — at current rates, that's potentially 15+ years of savings with minimal maintenance costs.
The pricing breakdown includes equipment, installation labour, and applicable taxes. Use the sliders to adjust system size and battery capacity to see how pricing and payback change.
STC Rebates Tasmania
STC rebates in Tasmania are calculated based on your system size, location zone factor, and deeming period until 2031.
