I'm curious how you see this potentially increasing the cost of energy? Why can't we do both large systems and small distributed systems?

I see the following benefits:

1. Stabilises the grid

2. Smooths peak demands. Check the Price and Demand graph here: https://www.aemo.com.au/energy-systems/electricity/national-...

3. Increases supply -> energy prices decrease?

4. Accelerated move away from coal generation and towards renewables.

5. Job creation (solar and storage installation)

Drawbacks:

1. Renters, lower income houses and apartment dwellers don't have access the subsidies

2. Exposure to dodgy installers and systems just like we saw with the Australia solar scheme.
