The best solar panels depend on your roof space, budget, local climate, electricity use and the installer’s workmanship, rather than one universally superior brand. Compare efficiency, product and performance warranties, degradation rates, temperature performance and whether the model is listed by the Clean Energy Council for Australian installations. A reputable installer should design the system around your home and explain expected generation, inverter compatibility and after-sales support. Obtain several itemised quotes and check current guidance from the Clean Energy Council or energy.gov.au before making a decision.
