clearly out of date information you are working on there
For the record... home solar payback period is typically now 3-5 years (improves with setup size.. but 5kW setup is standard and is ~4 years paid back) with an effective life of 25 years on the panels home battery installations are not really cost effective at all - not because of payback period, but effective life and warranty... plus costs & capacities are rapidly improving - which makes an investment now possibly superseded before payback is complete... even then.... payback can be still occur around 10 years... Plenty of good real estate data shows having solar panels on the roof actually improves resale value.
commercial grid scale batteries however... 2 years payback and 10 year effective life - TOTALLY worthwhile investment ATM
You don't have to be green to support renewables... as you say... you just have to be able to do the math - renewables are changing the way that energy is generated and stored - AGL has not adapted enough and is feeling the pain of that in the form of negative sentiment and diminishing profitability
