Australia is a world leader in solar adoption with more than 3 million rooftop solar systems and almost one-third of Australian homes equipped with solar panels.
Regen Power managing director and renewable expert Nikhil Jayaraj said by 2025 rooftop solar capacity would surpass coal and this expansion must be accompanied by battery storage.
“In 2021, households in WA added 316MW of generation capacity to their rooftops, bringing the total residential solar capacity in the state’s main grid to over 1.35GW, according to newly released government data,” he said.
“The dramatic increase in solar output poses challenges for WA’s power system.
“When solar energy is favoured by weather conditions, it leads to a rise in periods of excessive oversupply.
“In order to resolve this issue the WA government has introduced a rule change that allows the network operators to control the output of residential rooftop solar systems.
