Reply to comment by KirkSheffler in eli5: how long would power stay on if the power company abandoned their post? by larsattacks94

I'm talking about Grid scale Solar and residential Net Solar, not residential or commercial Solar + Li-ion. If you're off-grid with your Solar + Li-ion you don't factor into grid loading anyway, unless you have high energy processes, like an industrial facility which uses Solar + Li-ion for office power and grid for like arc furnaces or something really energy hungry.

Solar does drop off hard in the evenings, and it's a big problem they call "The Duck Curve". Go ahead and check out some of the online papers about it.

I understand that and it’s the same concept/ principles. They have techs who monitor and rotate between the fields keeping them in order/ up and running. The company I work for ‘Faith Technologies’ is huge into green power, and we actually did the largest solar farm in the US. I’m just speaking from personal experience working on them it may be different overseas or in different regions.

As far as I know, Grid-scale li-ion (or lipo more likely) installs are super rare. A quick google says in 2021-2022 there was only 16gW of grid scale li-ion/lipo storage. Our peak usage is on the order of terawatts.

And yes there is a huge dip at night but during the day the fields are charging battery banks not using raw solar so at night if you’re not consuming a large amount of electricity it’s fine. And the banks can usually last a while on a single charge
