It's slowly improving and will only get better with the popularity of EV's. Even LiFePO4 batteries are considered much more environmentally friendly than previous tech. I got a quote a few months ago for solar + battery and that already included LiFePO4 battery storage.

The tech won't improve unless there's uptake and demand, which is starting to increase now. Australia has had subsidies for solar installation for a while now and costs for rooftop PV there are some of the lowest.

It's up to you if you want to trust the power companies, but in the 5 or so years of living in this house our power prices have only ever increased.

Still far from ideal from an environmental perspective, when the alternative is the power being used in the same building that is generating it.

I just don't think this is a cost effective policy myself

Ideally we should incentivize both residential and commercial installations.

Ideally, yes. We certainly shouldn't be incentivising house batteries though.
