Case Sharing 16 - Adelaide Community Household Energy Storage Project Plan
Created on 08.01
💡
Help South Australian families break free from electricity bill anxiety and achieve "energy freedom" with clean energy.
1. Project Background: The Energy Dilemma of South Australian Families
Electricity prices soar: In 2024, electricity prices in Adelaide reach AU$0.42/kWh (the highest in Australia)
Power grid vulnerability: The storm in 2023 caused power outages for over 70,000 households for more than 48 hours.
Policy benefits:
Home Battery Scheme subsidy up to AU$3000 per household
Solar Feed-in Tariff surplus electricity buyback price AU$0.10/kWh
2. Solution: The Golden Combination of Photovoltaics + Energy Storage
Typical household configuration (4-person family, annual electricity consumption 6000kWh)
Device | Specification | Function |
Photovoltaic system | 6.6kW (18 panels) | Annual power generation 9000 kWh (self-sufficiency rate 120%) |
Energy Storage Battery | 10kWh lithium battery | Nighttime power supply + emergency backup |
Smart Gateway | Tesla Powerwall+ | Automatic switch to optimal power consumption mode |
Power self-sufficiency logic:
3. Economic Analysis: Investment with a 6-Year Payback Period
Cost and Revenue (Taking a Typical Family as an Example)
Project | Amount |
Total Cost | AU$15,800 |
Government Subsidy | -AU$3,000 |
Annual electricity savings | AU$2,520 |
Electricity sales revenue | AU$300 |
Payback Period | 5.9 years |
System Lifetime Benefits | AU$45,000 (25 years) |
4. Technical Highlights: Adapted to South Australia’s Needs
Photovoltaic Optimization
Hail-resistant design: 3.2mm tempered glass panel (meets Australian AS/NZS 1170 standards)
High temperature performance: Power attenuation <5% at 50℃ environment
Energy Storage Innovation
Storm mode: Automatically switch to off-grid power supply in 0.02 seconds during a power outage
VPP Access: Join the AGL Virtual Power Plant program, annual revenue increase AU$200
5. Community Synergy
Power Sharing Model
During the day, surplus electricity is prioritized for supply to community senior apartments.
During the storm, energy storage users form a microgrid.
Trade green electricity through the Power Ledger blockchain platform
Scale benefits
Number of participants | Average electricity bill reduction | Community Carbon Reduction |
50 households | 65% | 120 tons/year |
200 households | 78% | 500 tons/year |
7. Policy Arbitrage Guide
Subsidy Combination拳
Federal STC: Photovoltaic system rebate AU$650/kW
Provincial HBS: Energy storage subsidies + low-interest loans
Local Council: Exemption from equipment approval fees
8. Implement a three-step approach
Assessment: Satellite Scanning Roof Compatibility (Free)
Design: 3D simulation of power generation (error < 3%)
Installation: Completed in 1 day (CBA certified engineer)
Summary
"When the South Australian power grid was still apologizing for the outages, these households had already taken control of their energy destiny with 'rooftop power stations + home charging treasures'—there is still light after the sun goes down."
