The announced disaster has taken place ...

https://www.techniques-ingenieur.fr/act ... ite-51088/
About a year ago the official website of the Ministry of Ecology announced that the solar road of Tourouvre in Normandy would produce 17963 kWh per day. Before retracting, lowering daily production to 767 kWh. Either 23 times less. The newspaper Le Monde echoed this fix 22 December 2016.

But production in the real world is lower. This high-profile (340 kW) route actually produced 409 kWh per day on average during the 2017 year


the installation is reported to 340 kWc ; all these panels installed on a rather poor roof of 1000 kWh / kWp / year would produce: 931 kWh / day

and on an optimal roof (1500 kWh / kWp): 1400 kWh / day

the solar road is not even half of the producible of a bad installation on the roof, nor the third of a good installation on the roof ...

The SNA Scop in liquidation

CLAIRE GARNIER Factory New the 21 / 03 / 2018

Diversification in photovoltaics did not allow Société Nouvelle Aeracem (SNA) to offset the loss of revenue in the CD / DVD, its main activity since 1980. The employee 70 company, based in Tourouvre (Orne), is in liquidation with judicial pursuit of activity for three months.

The Société Nouvelle Aeracem (SNA) of Tourouvre (Orne) which employs 70 employees was placed in liquidation by the Commercial Court of Alençon (Orne) February 26, with continued activity for three months. Buyers have until March 30 to submit their offers.

Faced with the development of online music, this company specializing in the pressing of optical discs (CD, DVD, CD Rom) had invested in 2010 in an assembly line of photovoltaic panels with a view to diversification. But, this diversification "did not make up for the loss of turnover in the CD" explains to the Usine Nouvelle Hervé Eymery, general manager, especially as the company is faced with Chinese competition in this sector.

SNA attracted attention in 2016 because it was chosen by the Colas group - world leader in road construction - to manufacture the photovoltaic coating for the world's first "solar road", in Tourouvre. This kilometer-long solar road was inaugurated on December 22, 2016 by Ségolène Royal. After development difficulties in 2017, SNA continued to deliver other Colas group projects with solar panels.

Vinyl record, CD / DVD, photovoltaic panels

Since its creation in 1950 (under the name of Aeracem) for vinyl record pressing, SNA has taken several industrial turns. Acquired by its employees in 1980, the company that has become Société Nouvelle Aeracem has started manufacturing optical discs (CDs, DVDs). Feeling his activity threatened by the development of online music, it turned to photovoltaics before being selected in 2015 by Colas to manufacture the "Wattway" tiles (photovoltaic coating) for its future solar roads. A great pride for SNA. These slabs contain photovoltaic cells which are encapsulated in several layers of materials, a few millimeters thick they are designed to produce electricity and ... withstand the passage of a 45 tons.

Little chance for the future of the solar road of Colas in these conditions .......

The eco tax is not such a bad idea but it should also apply to aircraft (scandalously tax-free fuel)
The porticoes were a bad idea at the time of the GPS which traces everything was simple to follow the loads without this pharaonic expense

scandalously tax-free fuel

+ 1. It has been revolting for quite some time. It is unfair. Why do we pay 1,5 + € per liter, while planes pay less than 50 cents?
A yes, the plane does not pollute? it does not emit CO2?

As a reminder Roissy + Orly airports consume more fuel than all vehicles in the Ile de France .... 20 000 liters of fuel every 30 takeoff seconds for A32x .... 110 000 liters by A380. If they were taxed like cars, that would make 100 000 € tax revenue per take off!
And we find normal that the planes do not pay these taxes.

We laughed a lot about the solar road Ségo, we criticize a lot the unfortunate 3 km of urban highway made to pedestrians and bicycles in Paris, but on planes ... well .. complete radio silence.

She produces that slab! : Wink: But that's not what will disassemble S. Royal so far ...

Enerc did not understand the world in which he lives!
by offending that diesel for aircraft is not taxed he does not see that the rich are more likely to travel by plane and the poor, many, rather cars .....
it is the rich who make the laws and the poor who pay taxes .... as of course, and in addition as they are more and more numerous, the base widens what is good for the durability of a tax.
and if we wanted to replace the thermal cars with electric cars, we would first have to know how to replace the taxes, it is the primordial question, otherwise how would all the parasites survive? Do you think about it?
when I see the number of subjects "neu-neu" at least or certain are concerned with finding alternative fuels without thinking about the essential, that is to say, taxation.
Do not forget which oil is an energy 6 times cheaper than electricity! a little economic thinking before doing technique, common sense!

Oil, or gas, is free; it is its extraction, its distillation and its transport which have a cost; as for its price, it is fixed mainly by the market, and by the parasitic taxes which accumulate throughout their human life ...

The same goes for electricity; the "raw material" is free; it is processing, transport and distribution that costs; plus obviously the taxes which also accumulate at all levels ...

Otherwise, the costs per kWh, electric or hydrocarbon, are very comparable "ex works", which share between 4 and 6 cts per kWh, taxes making the difference; With the difference that, as far as transport is concerned, 1 electric kWh gives about 0,8 kWh to the wheel, while 1 kWh oil gives rather 0,3 kWh to the wheel ...

So for the subject that concerns us here, electricity is much cheaper than oil; but nothing forbids to tax it so much, even more ...

Obviously, in thermal use, this reasoning no longer holds, or at least more completely ...

well seen, that photovoltaic slab, the project was not concrete. We take a hot Colas?

It's even worse than I expected. They remove the installation altogether so it is inefficient ...

Hello : Wink: ,

If we wanted to be serious, in terms of taxation of co2 or energy, we should also tax fertilizers (same order of magnitude as aircraft), and all materials used (concrete, etc ...) and goods marketed ... (gray energy)

In the comparison between planes and road vehicles, there are roads, financed by "the community", while planes only need a "parking space".
