Solar + Storage costs

No one talks about storage costs, heres my estimate:


Solar will provide cheaper power. Sun is free, no transport costs.
Solar PV farm can be mostly automated. Build next to grid power.

Solar panels with 25 year life could be replaced after 2040 when costs
should half. Compare with coal each day buy, transport and burn coal.


Clean coal 1GW plant cost $4 billion.
*Solar PV farm 1GW $1.6 billion.
**Powerwall2 lithium batteries 1GW $0.9 billion
Solar + Storage $2.5 billion = baseload power


In case of blackout in the day, storage can be used.

Coal has confirmed solar is cheaper and now wants taxpayer money.


Solid-state battery by 2025, long life lightweight more capacity
Twice density, fifth cost of lithium.

* India 2GW Solar PV $3.2 billion
** Powerwall2 14kW $11,000
