you just have to calculate it in kWh. : Twisted:

You've been the specialist since 2008...I don't think it's 60.000GW, but you should be able to tell us what is the peak power to be installed to produce 526.000TWh in these countries.

An average power of 300W seems to me to include night cycles...but we're not at 94% there! : Mrgreen:


I didn't quite follow Remundo's reasoning, in the desert, 300W is possible...

At home (Ardennes) I am at 120W per 1000Wp of annualized average power....In other words a 3 kWp installation will produce 120/1000 * 3 * 8760 = 3125 kWh per year...

In the South of France, it can certainly test the 200W...

Mr Simple, what next? You will do the eel to question my correct calculations from the top of your ramblings?

Already it depends on whether we have trackers or fixed panels.

But this is a somewhat secondary question.

As a first approximation, the 60 GW of average power from 300W/m² presupposes receiving 1000 W/m² at peak.

The peak power to be installed must be corrected by the factor 1000/300 = 3,33 roughly

Because the sunshine at the Zenith is 1000 W/m² in these regions.

Attention, my calculation, based on my real figures is 120W per 1000Wp, not per m2...(you also have Remundo PV, what are your real numbers)?

So 300W average over the year per m², even in the desert, that still seems like a lot to me...

In the best case, with current mono panels at the top, we have 250-270 Wp per m²...so 4 m² for 1000Wp so in m² should roughly be divided by 4 my 120W which falls to 30W annual average / m² ... it's still very far from 300W ... (the reality is between these 2 figures : Mrgreen: ) ...

Well, there you go!
It's not 60.000GW of raw power, it's about 200.000GW of peak power...
Not sure that it holds even on 1.000.000km2....Even sure of the contrary.
And in 2022 the global production of panels was around 200GW, we're going to have to really boost that otherwise we'll have 1000 years.

You have a weird calculation method, I've never seen that.

Conventionally, the load factor is mainly used, possibly expressed in H / year. This makes it possible to immediately switch to comparisons.

Ex: PV panels in Europe, this ranges from 900 (around 10%: Belgium, the Netherlands, Denmark, etc.) to 1750 H/year (Andalusia, Sicily, Crete, Cyprus, etc., i.e. 20%).
South of France, North of Italy: 1 H/year or 300%.

Well, I'll stop... It was just to say that reasoning like "Yaka put PV in the tropics" makes no sense. PV, it must first be put in each place where it makes sense, to produce electricity which will come in many places to replace production of fossil origin and possibly supply new consumers such as vehicles electrical.
Of course I have nothing against the fact that the countries of the intertropical band equip themselves, quite the contrary.

Well no NCSH and yes I'm a weirdo, that's why I get things done! : Mrgreen:

So yes, we can very well do the reasoning upside down and it is simpler and more reliable...

The hours of sunshine do not take into account the performance of the installation nor the masks nor the orientation etc etc... my method yes and I am therefore at 12%...

You all got lost in your convoluted calculations!
It is indeed 60 TWp or 60 GWp per 000 km1.
Remember, in general, we have 1 MWp at best for one hectare of land surface, so for 100 ha, we can have 000 GWp.

It would therefore be necessary to multiply by 15 or 20 the rate of production of solar panels, currently around 130 to 150 GWp/year.

Ah, the lambic!

no no, NCSH

I didn't get lost...

I spoke at the outset of 60 GW, which is also your estimate, of 000 TW.

on the other hand, you made a mistake by putting TWc (peak)

because 1000 km² produce peak 200GW, and not 60, in the tropics

1000 x 000 x 1000W/m² x 000% = 1000 x 20^2W = 10 x 14^200W
of km² x m²/km² x solar flux x yield
