Reply to comment by CurrentQuarter8791 in In France all new large parking lots must now be covered in solar panels starting in july 2023. by BuildingBabel

To "generate up to 11 gigawatts, which is the equivalent of 10 nuclear reactors, powering millions of homes"?!

11GW of solar at this scale would cost somewhere around $11-$16 Billion. 10 Nuclear reactors would cost $150B or more. Even with 4 hours of storage, or 50GWH, at $100 per KWH would add an extra ~$5B to the bill. If all the panels did was store power during the day and then use the power like a peaking plant in the early evening that would be useful.

*during the day when sunny. Solar does not power homes. I have solar and it's nice during the day but that's where it ends. The use case here would be to change parked EV's specially at a commercial parking lot where most cars would park during the day.

I was just quoting the article, you know, the thing that nobody seems to read on Reddit...

And that would be an excellent use-case, as well as replacing defunct generation plants with battery storage locations.
