"At the time the 2014 standard was written, solar panels were at most 250W per panel, but technology is quickly changing, and it''s not unusual for panels to be greater than 400W," said EL-042 Co-Chair Sandy Atkins. "Therefore, AS/NZS 5033:2014 was limiting for installation professionals," Mr Atkins finished.
