How we choose brands

We show a brand only when it's on the government-approved product list (EV chargers have none, so they need a published Australian datasheet), has an Australian office or warranty agent, and is widely used by Australian installers. Its standard warranty in Australia, with no registration needed, must be at least 12 years for panels, 10 for batteries and 5 for inverters. We check the official lists weekly and read each maker's documents ourselves. Brands are listed A to Z and never ranked. No brand pays to appear.
