What sets the price of a system with Trina Solar panels?
Installers quote Trina Solar panels as part of a whole system, so there is no stand-alone price we can source. System size, roof type, switchboard work and the federal STC rebate move the price far more than the brand. Our solar price guide covers installed cost by system size, and the STC rebate guide shows what comes off it in your zone.
