When comparing solar panels in Perth, look at the system’s expected annual output, panel and inverter warranties, installer accreditation, and how the design suits your roof and household usage. Perth’s sunny climate can support strong solar generation, but shading, roof orientation, export limits and your electricity plan will affect the value you receive. Eligible small-scale systems may attract STCs, with the incentive amount determined under the government scheme and applied through the installer or agent. Get several itemised quotes and check the installer’s credentials, product warranties and proposed savings before deciding.
