KW of solar panels produces roughly 1000kwh a year. So if it cost 4000 dollars for a KW of solar that's about 4 dollars a kWh for only first year or 20c over twenty years very crudely. But as I said it probably didn't cost 4000 dollars a KW as the article gives no details. It would make more sense to think of renewable costs as price per kWh but it's way too complicated and individualized for casual conversation.

It depends a lot if you are putting these on your roof in Germany or whether you are buying in bulk for some grid setup in Dubai. But 3-4kwh per day per kw of solar panel sounds about right for a lot of places in more Northern regions (i.e. not California). I think that is about right for places like the UK. It's more in the summer and less in the winter and you have to account for cloudy days too. Closer to the equator, it might be closer to 6-7kwh or even better. Places like Dubai or California get a lot of sun throughout the year and a setup like this would have the panels positioned optimally presumably. So, I'd guesstimate at least 3-5 cents per KWH is a reasonable expectation for this setup. Recent bids are actually closing in on 1 cent per kwh. E.g. there was a Portuguese bid for 1.3 dollar cents per kwh last summer. I'm sure that probably has been undercut since then by someone. And Portugal is pretty far North compared to California, most of which would be at the same latitude as Sub Saharan Africa. So, potentially I am low-balling it. Probably in the next few years we will get sub 1 cent bids happening with some regularity. https://cleantechnica.com/2020/08/30/new-record-low-solar-price-bid-1-3%C2%A2-kwh/ https://cleantechnica.com/2020/08/30/new-record-low-solar-pr...
