Solar Panels: An Overview

Solar panels capture sunlight and convert it into electricity, providing clean energy for your home. A 6.6 kW solar system is a common choice for households in Perth, offering optimal energy production for small to medium families.

Cost Breakdown

  • 6.6 kW Solar System: Typically costs between $5,500 and $8,000 including government rebates like Small Technology Certificates (STCs), which lower costs by approximately $2,000 in 2025​
  • The system includes:
    • Solar panels.
    • A solar inverter (converts DC electricity to AC for home use).
    • Installation services.

Potential Savings

A well-placed 6.6 kW system can generate around 30 kWh per day, potentially saving up to $2,290 annually on electricity bills​.

Solar Batteries: Storing the Sun

Adding a battery to your solar system allows you to store excess energy for use during the night or power outages. This reduces grid dependency and maximizes the return on your solar investment.

Cost Breakdown

  • Prices for solar batteries in Perth range from $5,000 to $15,000, based on capacity and brand:
    • Small batteries (3–5 kWh): $5,000–$8,000.
    • Medium batteries (6–10 kWh): $8,000–$12,000.
    • Large batteries (10+ kWh): $12,000–$15,000​
