Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Am I to understand then, northern hemisphere grids (EU, Germany specifically) which are too far from the equator to exploit "local solar irradiance", ought to define investment in and feasibility of decentralized PV installation, generation, and transmission everywhere else on the planet?

How catholic.

I neither said nor implied any of those things. My point was that, while being limited seasonally by latitude, solar WAS able to make a significant, cost effective, contribution to the grid even in Germany. Of course the same equipment, installed within 20 degrees of the equator, would give a much better result. So it becomes a trade-off of transmission cost vs. reduced generation. Were technology to greatly reduce the transmission cost then locating solar generation near the equator would become more desirable. Morocco is currently of interest because of its proximity to Spain and the European grid. But Spain would do just fine, IMO, were it not for local idiot politicians like Rajoy who shut down planned projects for political purposes as well as rendering existing facilities less viable by changes in regulations.

m'k.
I did ask. Now I know. Equatorial PV installations are useless unless their transmission terminates as far away as the northern hemisphere, eg. EU consumption.
Technically the biggest limitation is power transport. Else the equator would be ringed with solar power installations.

So.
Morocco is currently of interest because of its proximity to Spain and the European grid.

Who specifically, what organization, is suppose to fund and construct PV installation and transmission lines to export surplus electricity to Spain from Morocco, if not the ideal ring around the equator?

Not being a member, I'm ignorant about Club of Rome networking activities in Morocco.

LOL! Impute any assumptions you want to what I say. But I do believe that African countries should build their own PV installations for their own people and their neighbors with what ever money can be pried from the hands of their own elites. That is what governments ought do, even if so doing is the exception and not the rule in most countries today - notably so in the USA.

Have you any recent examples to support this belief?

It was a normative, not a positive statement, and NO, I have no examples that spring to mind - sadly. The general situation regarding leadership in most of Africa is dispiriting. But then so is it in the USA.

Equatorial climates tend to be suboptimal because they involve lots of rain and cloud cover. Desert climates like the Sahara are ideal, and not just because of their proximity to Europe. Transmission costs need not be excessive once economies of scale are achieved.  The Sahara isn't much good for anything else. It could be a very good export and foreign currency earner for Saharan countries were it not for political instability threatening installations and transmission lines. Failing that, southern Spain would be the ideal locations were it not for a lack of political imagination.

Note, however, that production tends to peak around midday which might limit power availability at other times.  Ideally an east west middle eastern and north African grid spanning form Saudi to Morocco would provide power throughout most of European daylight (and peak demand) hours. In the longer term, a global grid extending all the way to Mexico could provide power throughout northern hemisphere daily demand cycles and valuable revenue and employment for more southern countries. (In return, northern installations could provide wind power for more southern countries at night or in winter).

Yes, on either side of the equator by 20 degrees I should have said. Namibia is another great location. It could power South Africa and most of Africa south of the equator if adequately built out. Similarly with Mozambique on the east coast. Solar thermal and east-west interconnects could stretch the time period served.

A north south Namibia Sahara interconnect could also help to re-balance summer/winter production peaks more in line with demand cycles.
