About this data
The model code, rated power and approval dates come from the CEC Approved Products Register. Other specifications appear only where we hold the manufacturer’s datasheet for this model; a specification we cannot source is left off the page. The price and the Perth performance figures are our own estimates, not datasheet figures. Panel availability and pricing vary by location and installer. Not all listed models may be currently available in Western Australia.
