Queensland's subtropical and tropical climate produces outstanding solar generation year-round. Most homes are all-electric, removing the need for gas switching but making solar self-consumption and battery storage the primary levers. High air conditioning loads during summer create ideal conditions for large solar systems and battery pairing.
