Solar road Ségolène laughing

[Did67]

Let's be lucid: no doubt Colas is right. If the subsidies are high enough, THEY earn money and they can hire!

The rest is not their concern. The "productivity" of electricity should be a minor resource in the business plan. So that it curls is not very serious!

State of the road 2.5 years later ...

Nice "development" ... We would have liked to laugh about it if it were not so pathetic (not the comparison but the project in itself) ... It is certain that France will "shine" internationally there!

But on the merits, I agree with Didier's opinion ... All of this was just a great com operation intended to take a few million grants!

It will be neither the first nor the last project of its kind!

On the Tweeter link we find this report of 30 minutes on solar routes but with hexagonal modules undoubtedly more adapted and thoughtful:

[Christophe]

I strongly advise you to view this report because it goes well around the question ... (activate the subtitles + auto translation, it's understandable most of the time)

In fact, solar routes would only be really valid in one ecumenopolis!

And again ... there would remain the surface of the oceans ... and existing roofs!

In Normandy, the fiasco of the world's largest solar route
The pilot installation, which covers 1 kilometer of departmental road in Tourouvre-au-Perche (Orne), is neither energy efficient nor economically profitable.

By Igor Bonnet Posted on July 22, 2019 Le Monde

Some 2 m800 of photovoltaic panels glued to the asphalt, on a section of one kilometer long on the departmental 2 which leads to Tourouvre-au-Perche, a small town of 5 inhabitants, in the Orne. The first “solar route” in France, inaugurated in December 3 by Ségolène Royal, was to foreshadow the deployment of this unprecedented technology on 200 kilometers of roadways in France.

Two and a half years later, the announcement effect has not stood the test of reality. Amputated at the end of May by a hundred meters too damaged to be repaired, the road is now pale with its tattered joints, its solar panels peeling off the road and the many splinters that enamel the resin protecting the photovoltaic cells.

"The engineers of this project surely did not think of the tractors that were going to roll on it," mock Pascal and Eric, two roofers in the corner leaning on the counter of the Café de Paris, in Tourouvre-au-Perche, where they comment on the setbacks of this first solar route.

In addition to a premature wear of the slabs due to traffic and their fouling due to the leaves of trees come to rot there, the coating generates so much noise for the residents that the traffic speed had to be lowered to 70 km / h. Worse, thunderstorms caused the road to break up.

Far from the expected 790 kilowatt hours (kWh) per day

In the end, the latter is far from having kept its energy promises. ATAfter having produced in the first year just over 50% of the expected 790 kilowatt hours (kWh) per day, for a total of 149 kWh over the year, the equipment generated 459 kWh in 78 and 397 kWh since January , as indicated in early July, the statement of the association for the promotion of photovoltaics BDPV, which lists the production of solar installations in France.

Financed by public funds up to 5 million euros and supported by the company Colas (Bouygues group), the Wattway subsidiary had the ambition to supply the equivalent of the annual consumption of public lighting in a city 5 inhabitants.

The director general of the services of the departmental council of the Orne made his accounts: “The receipts of sale of the electricity produced by the road were to bring us 10 500 euros per year, details Gilles Morvan. In 2017, we received 4 euros. In 550, 2018 euros, and for the first quarter of 3, we are at 100 euros. "

2800 m², we're going to be nice, it's around 280 kWp

on an average roof at 1200 kWh / kWp, this would give 280 x 1200 = 336 kWh

only generated 80 in 000, less than a quarter of a normal installation.

As I had announced in 2017, all these branques have managed the tour de force of making a bad road, a bad photovoltaic power plant, and all this for much more expensive than a good road and a good power plant separately ...

Bravo the clowns!

I am quite flabbergasted that the director general of the services of the departmental council of the Orne is doing so badly his accounts because even at 10 500 € for 5M € invests the break-even point is around 500 years ...

So if the road only pays half, we would be 1000 years back ...it does not make a big difference in the scam of the thing !!

On the other hand, predicting the failure of this route was not really an achievement! If I allow this remark, it is because I was one of those who announced the inevitable collapse ...

What's impressive about this story, and one that should question, isn't that "it was predictable." It was.

But ;

a) that a minister does not know anything about it, let us admit

b) that his cabinet does not muffle, let's admit

c) that the department is convinced ??? Were they "socialists"? And so friends ???

d) that Colas makes butter with subsidies, obviously, it's their job

e) they manage to convince as many people ???? Is there not one person in this whole system who still has a pair of balls?

f) that we find like that 5 million euros for the "dancer" of the Minister, ??? [note that it was like the troupe of Béjar, question dancers around the minister - VE, etc ...]

g) that as written, the TRI is, in the best of cases, 500 years and that does not tilt ????

h) let's push the reasoning a little further: "is it enough that something is fashionable for it to authorize anything?" [subject of bac 2020]

i) de Rugy's lobsters are ultimately quite harmless, don't you think?

It is not very serious, what I say. Though...
