How does Solar work?
Learn how Solar Energy works with our easy-to-understand explanation below.
How a Modern Grid-Connected Solar System Works in Perth
In Perth, Western Australia, a modern grid-connected solar energy system combines advanced technology to maximise energy efficiency, reduce electricity bills, and support sustainable power generation. These systems use high-efficiency solar panels, smart inverters, and intelligent energy management to harness and optimise solar energy.
How Do Solar Panels Work?
Solar panels generate electricity through the photovoltaic (PV) effect. When sunlight hits the silicon-based solar cells, it excites electrons, creating an electric current (DC power). This direct current (DC) energy is then converted into usable alternating current (AC) through an advanced solar inverter, making it compatible with household appliances and the Western Power grid.
Key Components of a Perth Grid-Connected Solar System
-
High-Efficiency Solar Panels
- Utilising advanced photovoltaic technology, modern solar panels achieve higher energy conversion rates, meaning more electricity is generated from Perth’s abundant sunshine.
- Many Perth homeowners opt for tier-1 solar panels for maximum reliability and long-term performance.
-
Smart Solar Inverter
- A high-quality solar inverter is essential for converting DC power into 230V AC power for home or business use.
- Real-time optimisation technology adjusts energy production based on solar intensity and grid requirements, ensuring higher energy efficiency.
-
Integrated Switchboard & Smart Meter
- A solar smart meter precisely tracks solar energy production and household consumption, enabling better energy management.
- Many Western Australian households benefit from feed-in tariff incentives, earning credits for excess solar energy exported back to the grid.
- Some smart meters can dynamically control electric vehicle (EV) chargers, allowing for intelligent load balancing and cost-efficient charging.
-
Battery Storage & Enhanced Grid Connection
- Solar battery systems store excess energy for use during peak times, reducing reliance on Synergy electricity tariffs and maximising solar self-consumption.
- Integrated with the South West Interconnected System (SWIS), solar batteries help stabilise grid supply and provide energy security during peak demand.
Recent Solar Energy Advancements in Perth
- Waroona Renewable Energy Project: A major development increasing battery storage capacity by 12%, extending the availability of solar-generated power.
- SWIS Expansion Plans: The Western Australian Government is investing in renewable energy infrastructure, enabling more homes and businesses to connect to solar energy solutions.
- Smart Grid Integration: With more Perth households switching to solar, innovations in grid management and energy storage are enhancing system stability and efficiency.
Why Choose Solar in Perth?
- Significant electricity bill savings with solar feed-in tariffs.
- Maximise Perth’s high solar exposure (averaging 8-10 sun hours per day).
- Reduce carbon footprint while increasing energy independence.
- Take advantage of government incentives and solar rebates.

Metering and System Performance for your home
Metering Requirements for Your Solar System with Australis Solar
When installing a solar energy system with Australis Solar, ensuring the correct metering setup is crucial for tracking imported and exported electricity.
Net Metering vs Gross Metering
- In Western Australia (WA), a bi-directional meter is required for most solar systems. This is known as “Net Metering”, where the meter records both the energy you consume from the grid and the excess solar energy exported back to the grid.
- Some other states use “Gross Metering”, where two separate meters measure imported and exported electricity independently.
Renewable Energy Buyback Scheme (REBS) & Meter Upgrades
Australis Solar applies on your behalf for the Renewable Energy Buyback Scheme (REBS) through your energy provider (e.g., Synergy or Horizon Power), they will determine whether your meter needs to be:
✔ Reprogrammed to support solar energy exports
✔ Upgraded to a bi-directional “import/export” meter
If an upgrade is required, your energy provider will arrange for a technician to install the new meter. In some cases, this may be done without prior notification.
Confirming Your Meter is Solar-Ready
After installation, check for a small green “Import/Export” sticker on your meter. This confirms that your solar system is fully connected to the grid and can start earning feed-in tariff credits for exported solar energy.

Maximising Your Solar System’s Performance with Australis Solar
The efficiency and output of your solar energy system depend on several key factors:
✅ Panel Orientation & Tilt – North-facing panels typically generate the most energy in Perth’s climate, while east- and west-facing panels optimise morning and afternoon production.
✅ Geographic Location & Climate – Your system’s output varies based on local weather patterns, with Perth’s abundant sunshine providing excellent solar potential.
✅ Shading & Obstructions – Trees, buildings, and other obstructions can reduce energy generation, making proper placement essential.
✅ Panel Cleanliness – Dust, dirt, and bird droppings can lower efficiency. Regular panel cleaning ensures optimal performance.
Seasonal Solar Performance in Perth
☀️ Summer Peak: Longer daylight hours and clear skies result in higher solar energy production.
🌧 Winter Dip: Shorter days and increased cloud cover may reduce output, but Australis Solar designs systems to maximise year-round efficiency.
Accurate Solar Production Estimates Before You Buy
At Australis Solar, we provide a detailed solar performance estimate before installation, including a seasonal energy output graph tailored to your location. This ensures you have realistic expectations of your system’s performance throughout the year.
The table below shows the average kilowatt hours (kWh) of energy that a 1 kW size solar system can generate per day in various parts of Australia. The calculated estimated performance of your system is based on your specific set up – panel direction, tilt, geographic location etc.
