Price of a solar panel: evolution of the photovoltaic Wp (peak Watt) cost




by Christophe » 10/06/08, 12:43

The doc date of 1999, updated in 2006 but currently, in 2008 one is FAR 2 € the Wc for the only panel (envisaged).

Details for an 2003 installation:

Cost of investment of installed capacity in 2003 (small installations):
- PV modules only: 3 € / Wc in large series
(down to 1,6 € / Wc envisaged in 2010)
- installation: 1,5 € / Wc
- inverter: 1,5 to 0,8 € / Wc (500 W to 5 kW)
- storage on batteries: 3 6 € / Wc according to stored energy
(about 0,15 € / Wh so 3 € / W is equivalent to 20 hours at Pmax)

Total without battery: <6 € / Wp


To have an order of magnitude of comparison: a small generator (which is now found in all brico) 1kW costs less than 150 €, a cost per Wc of 150 / 1000 = 0,15 € / Wc ...I bet that without the subsidies the cost of the kWh PV is worse than the cost of this generator ... even with gasoline 1,5 € ...

You laugh ! Just try to find the PV at wholesale price below 3,7 euros the watt peak to see! Add to that the UPS: look on the Internet how much is an SMA Sunny Boy 2100, for example, it is an average size. To this must be added the price of the labor (very expensive roof, a lot of wasted time to install the safety equipment and during the showers), the green meter, the protection, the special cables anti UV and the reception by an approved body.
In fact the advertised price is ridiculously low and should only be achieved for low-performance equipment on flat roofs (where you do not have to waste time disassembling tiles, or worse, slates.
Anyway, what is interesting at Econo is their heat storage system under the screed at "relatively high" temperature (15 °), combined with underfloor heating and a heat pump which, in these conditions function with good performance.

In China, it is possible to buy, by full container (250.000 euros by paying in advance to 2,9 Watt crest, but these unaccredited signs can not be the subject of premiums, tax reductions, receipt by a accredited body, etc.

As for delays ... it's another story: to plan months for 240 peak watts, a few weeks for 160 .... It is the law of supply and demand.

1) It's not me that made the curve huh ... and I'm not kidding, on the contrary I cry rather ... see 3)

2) Your remark confirms what we thought: there is a coupling with oil ...

3) Do you know the paradox of solar? Before it was expensive because there was no demand, now it's expensive because it has demand (and subsidies).

We do not care about our mouth yeah ...

So your PV overcharged and never profitable without the help of your neighbors keep them! I'll do a little solar mountain for 100 €! :D : Mrgreen:

ps: are you wholesale prices in $ eh?

to stay in the dough ....
the other day on the news they intervened a panel manufacturer who "surfiai on the oil crisis" (expressoon of the journalist)

he spoke of exceptional growth, investment in productivity gains, etc.
but price drop engendered by the effect of masee that slab : Mrgreen:

Elephant, you'll read this: https://www.econologie.com/forums/equivalenc ... t5501.html

For the exponential growth, how many solar installer and manufacturer went bankrupt in the 80 years when the price of oil dropped? Answer: a max ...

So these journalistic speculations ..

Moreover the growth of thermal solar stagnates in Germany ... hey ...

In fact, there are bonuses because states must spend 9% of their energy investments on renewable energy. In Belgium, this obligation is passed on to electricity distributors who pay all their customers to produce solar or wind power, so as not to pay fines, via green certificates.

In fact, still in Belgium, it is the green certificates that pay off and the State bonuses that pay off the fastest (3500 + 3440 euros + still 3440 if the operation is carried out over two years), i.e. 10500 euros on 25 to 30.000 euros that the installation will "bring" over 30 years.

Christophe: no prices are in euros.

and where did we see that I said that prices were related to the price of oil? On the other hand, in our depreciation tables, we take into account a probable evolution of the price of the Kwheure.

.

There is at least one that will not go bankrupt! the one Total has 50% : Cheesy: : Cheesy: (It's not a joke)
A Belgian company, whose name I have forgotten.

that explains why Sarko wants to entrust the development of new energy sources to total : Mrgreen: have experience : Mrgreen:
