It will not, not even close to that. You are being deceived. This deception is willful, because it is obvious to anyone who has any idea about realities of energy generation. The linked article, however, while not literally lying, omits some obvious facts, the goal of which is to make you believe falsehoods.
The article talks about "installed capacity", and compares installed capacity of photovoltaics vs. nuclear power plants. It is extremely deceptive to make such comparison without taking into account the notion of capacity factor, and the proof of this is that you have successfully been deceived.
The nuclear power plants typically generate north of 90% of their installed capacity, averaged over the entire year. The photovoltaics in Europe, on the other hand, typically generate 10-15% of their installed capacity, averaged over the entire year. This is caused by the unfortunate fact which is that the sun doesn't shine at all for at least half of the year, and for the significant part of the remainder, it is occluded by clouds, or shines at suboptimal angle, preventing the panels from reaching their maximum generating capacity.
This means that 1 GW of installed nuclear power capacity is worth at best something like 6-9 GW of installed photovoltaic capacity. At best, because photovoltaic generation will mostly happen on summer days, resulting in excess supply and so low value of generated energy. In winter, when photovoltaics generate relatively little energy, and the energy demand is high due to heating needs (especially during the night), the value of 1 GW of produced nuclear power will be higher than value of 1 GW of produced photovoltaic in summer.
The result of this is that covering half of all parking lots in France with photovoltaics is effectively worth less than a single nuclear reactor. This is obvious to anyone who pays even minimum attention to the economics of energy production, but the activist-media complex works very hard to deceive the public, leading them to believe that photovoltaics are already cheaper than fossil fuels and nuclear power. They are not, not even close, and this is even ignoring how nuclear power in France subsidizes solar/wind in a deliberate, systemic way.
- gpvos 4y agoWhat makes you think they didn't already take that into account? There are really an awful lot of parking places. Also, the panels will give electricity at the same times we are going to want airco due to global warming, so at least it helps to cover that need.

- hdhrufjdi 4y agoGood thing that wind power is stronger in the winter, thus complementary to solar energy. > They are not, not even close, and this is even ignoring how nuclear power in France subsidizes solar/wind in a deliberate, systemic way. Source? Do you also want to tell us about the subsidiaries of nuclear energy in France?
- fulafel 4y agoAnd of course the main way nuclear got help more from subsidies is the huge early amounts of taxpayer funds poured into its R&D and military use since the 40s - if wind and solar had gotten even half of that, renewables would be decades further along and further down the cost curve by now.
- ctz 4y agoThat's an awful lot of vitriolic words to express: comparing kW and kWp is a type error. > This is caused by the unfortunate fact which is that the sun doesn't shine at all for at least half of the year And factually incorrect. Currently sitting in Northern Europe making 5.05kW from a 5.6kWp installation.
- locallost 4y agoYou're making a case against solar panels but that is not what my comment was about. If they're worthless they're worthless, but there's more than enough space for them.
- yencabulator 4y ago> the sun doesn't shine at all for at least half of the year Hyperbole much? The polar night is a lot further north.
- xyzzyz 4y agoNo, I am talking about regular night, which adds up to half of the year.
