What are solar panels and why do they matter in Australia?

Solar panels capture sunlight and turn it into DC electricity. The inverter then inverts this into usable AC power — that’s the electricity your home runs on.

With well designed solar systems, you can lower your bills and reduce reliance on the grid.

If you’re in Perth, Western Australia, installing solar panels is one of the smartest ways to take control of rising electricity prices.

With generous solar rebates, low maintenance, and long warranties, it’s never been a better time to go solar and become energy secure.

Solar panels use photovoltaic (PV) cells to absorb sunlight as direct current (DC) electricity. An inverter then changes this into alternating current (AC), which powers your appliances such as dishwasher, lights, air conditioner etc.

Any excess energy can be either be stored in a battery or exported to the grid, sometimes for a feed-in tariff if you’re eligible.

There’s no one-size-fits-all, but here’s what to look for:

• High efficiency (above 20%)
• 25 to 30-year performance warranties
• Strong local support in Australia
• Reliability and Durability
• Proven performance in hot Aussie climates

There’s no single “best” panel — but some brands stand out.

Choosing the best solar panel in WA depends on your budget, roof space, and energy goals. Some brands are known for premium performance and long warranties, while others offer solid value and fast payback. Here are some of the top solar panel brands trusted in Western Australia:
