I was quoted around $15,500-$16,000 for a 12.8 to 13.5 kWh battery plus install for comparison.
My understanding is the grid will only pull from solar if required. Is that so? That’s how my solar setup works on my caravan, so not sure if it’s the same.
I work from home. So my solar (house and caravan) are all utilised heavily during the day.
I’m sure many do now also. That, and timing hot water heating, diahwasher, washing machine. Etc. All should help
@makingStuffForFun @PetulantBandicoot “the grid will only pull from solar if required” You export what you aren’t using or storing at the moment of generation. The only question is how much that earns you - or costs you. The electricity has to go somewhere and it’s not like you can just let it run out on the ground :)
You see, that’s the opposite of my caravan’s solar. It can sit up there in the full sun and potentially generate a lot of power, but it won’t send a single thing to the caravan or the batteries unless they request it. So the batteries and the usage of the caravan pull power from the panels, but the panels do not push power, so to speak.
So that makes me wonder if the solar panels on the roof are the same. The reason I say that is that the electricity companies want to charge us for solar generation because they say that we are feeding so much power into their grid that it’s stressing the grid out. But if it’s the same as my caravan solar then it is not. And I guess that’s why I was hoping that somebody who knows about these kind of things could put some input in.
that’s a good question. I think it’s due to the scale. Household also always runs through an inverter to supply mains to a house, and interacts with the mains board whereas a caravan usually runs the standard regulator (which manages load requests)
The grid is effectively an (nearly) unlimited sink. So nearly all your power you generate gets pushed into it.
The catch is that as we all collectively push more and more power in, it increases the frequency (50hz -> 50.1hz), and most inverters have a cuttoff if the frequency gets too high. But as far as I know, that almost never happens, but if it did, that could cause a large set of power generation to drop offline simultaneously, which would then cause a frequency drop and a subsequent brownout.
This is the best summary I could come up with:
“When I’m talking to my neighbours and friends, they are also increasingly frustrated, angry even, about what they see as a lack of action to help them manage electricity prices to their betterment,” he said.
Mr Coffey wants to install a battery system so he can store the solar power output when he’s “not at home in the middle of the day”.
Last year, AEMO CEO Daniel Westermen said the 3.5 million rooftop solar systems across Australia — surging when the sun shines and dropping off when it sets — could pose risks to grid stability.
Queensland Energy Minister Mick de Brenni said the home battery subsidy program would be evaluated to “inform further government consideration of additional support for households to adopt technology to lower bills and reduce emissions”.
The Queensland opposition did not directly respond to questions about whether it had plans to subsidise the cost of home batteries for people to capture solar power during the day.
Dr Asma Aziz, an expert in renewable energy at Edith Cowan University, said while the cost of batteries is coming down, it is still prohibiting many from investing in the technology.
