Huge since true.

"It costs just $33/MWh to transform daytime solar into dispatchable solar"

And no, that doesn't yet account for that storied Dunkelflaute. Then again, the typical gas LCOE doesn't account for Putin's whims or other geopolitical vagaries.

@gwagner that's 3 cents per kWh - so - why don't we do it then ??? Politicians bought by fossil fuel money ?

@bonno @gwagner to be fair, we’re talking about a state in India, way closer to the equator. Looking at e.g. Central/Northern Europe, the yearly distribution of sun varies a whole lot more. But yeah, we as humanity should be building way more of those batteries to power our life and houses, I’m with you on that.

@lpv @bonno @gwagner

On a sunny days I can get over the night with a 100W base load - just with a single standard-sized 400 Wp panel and 1.5kWh battery.

And that in Europe (Winnipeg/CAN latitude), in late february.

With a total investment of ~800€ that will last 10-50 years. Halve the price for bigger installations.

ROI in under 3 years.

Assuming 20 years lifetime, that's 4.5ct/kWh for a tiny-scale "installation".

@lpv @bonno @gwagner

granted: "on a sunny day". In dull, dark, overclouded mid-winter that can drop to 1/20

@vampirdaddy @bonno @gwagner good for you! Every step counts and it is great to see it working for some. And more and more each day. And what happens at the moment in Iran could be another catalyst.

@bonno @gwagner capacity. To make the switch, you need massive capacity. Prices will go down as well. So it can and will be done, will cost time, so let's get this moving as fast as possible. While at the same time increase solar and wind capacity and networks.
