With the recent closure of a brown coal powerplant, power customers have been warned they might suffer power outages if the draw on the system is excessive on hot days due to air conditioner usage.
The solar array fitted to my roof this morning would be at its most efficient under such weather conditions. Household power use comes initially from the solar array, only drawing on the national grid when usage exceeds generation capacity.
So when I’m using my A/C in cooling mode most if not all of its electricity usage will be from the array. Much less likely to suffer a power outage.
