I believe that the new technology and conglomerat entry threats are sometimes overated. What these Chinese solar 11's are working on perfecting is to get a stable quality level output at low production cost, when run in mass production. Not reaching something in a lab. This difference is much bigger than many think. It's not just an IP portfolio that decides the winner, it's perfecting organization, manufacturing processes and technology and production platforms. It's all about the total net result of mass production.

The solar 9 have two cost disadvantages relative to a conglomerate like the ones mentioned who decides to invest heavily in solar: 1) They can be leapfrogged technologically by the conglomerate's massive investment in state-of-the-art production lines (technology is readily accessible either in-house or through 3rd party suppliers like Centrotherm or Manz) 2) The solar 9 have accumulated a huge debt burden which leaves them with higher interest expense and higher refinancing cost relative to the conglomerates.

So I pointed out to the limitation of the wafer processing. All those improvements are about yield, purity leading to efficiency. Sorting is a mechanical process of finding efficient material, by measuring tools in automation or by hand using tools to recognize characteristics required to process it further. The percentage of quality wafers is less than total production.Quoted
Good wafer is really a purity of the poly and perhaps chemistry of the junction. Good poly wafer is one sorted from the core of ingot, where mono seed was closest. Sorting is means to find it not a produced it. All the claims are still a lot of hogwash. The cell is the heart, where technological know how, can take the wafer of choice and improve it.

If this is the case where are they now?
When times were fine they were up there claiming big expansions. Nothing happened and they are sitting under the rock. I wrote an article about lower pricing being an instrument to eliminate competition. Many accused China of it. If this is the case clearly price has impact on those companies.
Quoted from "odyd12"
The free cash flow, is an illusion for many highly divested companies, who need to worry about LED, washing machines and phone businesses they manage. Look at Sharp. On its knees, outsourcing to Taiwan, closing Japanese operations.
Quoted from "odyd12"
In my opinion they do not have technological advancement advantage.
Quoted from "odyd12"
I am not sure how any of those companies would take years of operational savvy from Yingli or Trina and overnight got ahead. Last blooming cycle did not show it. I also think that mass solution in technological advancement is highly dependable on Chinese demand. Specific solutions will be build with leaders and in-house developed technologies for mass production based on operational savvy. Lab made success by Samsung could not be transplanted into mass produced modules. Samsung modules were the most expensive to make along SolarWorld's and commended even higher prices on the market.
Quoted from "odyd12"
Money is not an issue for those 9 companies.

Klothilde I think there will be a korean wave. Korea has been big in solar before and you can see it in the support and joint ventures etc.

If cost is constant, efficiency reduces it per watt. What I am driving it is a raw material costing in each vertical. If you making boards you lose parts of tree, you make HP wafers, you do not get 100% yield. Yes, you may have a low cost; perhaps the lowest in the industry, but that processing does not include costs of handling those losses. More so, If you making cells you buy entire shipment of one range efficiency wafers. This naturally creates even more costs for wafer manufacturer, since demand is specific yet the process is not.
The pressure on wafer margins is incredibly high because of subpar product existence. So SOL picks its HP wafer for its modules. 80% of all wafers made by SOL are HP or is it 70% or 60%. I am not talking all lines, I am talking HP line.
However company like HSOL can buy narrow range of high efficiency wafers at the 0 margin price (today). Even by not disposing of waste, HSOL is ahead.
The processing cost per watt they provide in PDF (SOL), is not the cost of goods sold they provide in the accounting for it, so costs are more than the process cost.
When I started this discussion, my view was that wafer is not point of differentiation and evolution in next couple years is not attached to wafer but cell. Why so: SOL will sell its best wafer to public, the same one, which is in its best module.
The customer needs to have better cell and module technology to beat SOL module, granted but I believe they do.
Furthermore I also believe that cell makers, who make cell for SOL, will not be able to compete with leading cells created in-house projects, in my revolution scenario. Perhaps this why Li wants the specialization on wafer to go on, he seems putting a lot of money into this as he wants to be “the only” wafer in town.
BTW how do you calculate averages of HSOL and TSL to be 240MW modules?

I am only stating there is wasted material in production wafers, to largest degree that any other vertical. No need to describe processes I am familiar with them. You and I agree on this. Mono has less waste as the purity of poly allows to be reused.I think you're oversimplifying the discussion, by saying that it's in the cell processing is where things happen. Look at YGE. Both for mono and multi they are differentiating in the ingot step, with growing n-type mono ingots and the recently announced "develop high-efficiency multicrystalline ingot casting technology based on gas refrigeration".
The production line (ingot) will have only a % of HP wafer and produce 1.8GW , what is the percentage of HP?I'm not sure what you mean. All SOL's 1.8GW non-mono "lines" are the same now. They can be set to make either quasi-mono or HP multi. My point is that a year ago their quasi-mono averaged 245W and their multi 230W, but now they both average 255W.
It is important as the cost factor and overhang. It falls in to other point.That's an obvious, but for me quite irrelevant observation.
Again, I am explaining this. Processing costs are in COGS, but COGS is not the processing cost you see in supplemental info in PDF. I believe that obsolete material gets written off, quarterly and this is cost you do not see in the deck. Yes cell processing has losses and the same happens. However cell loss due to damage is a lot more controlled these days.I'm not sure what you mean here.
So check the interview with had with SOL. Right there most of the HP wafer will be going to their modules. But that is not the case for wafer seller. If they will compete with other wafer sellers, they will put the same wafer in own module as the next guy who bought their wafer. You do see that the only case of differentiation is the "cell" here, right?Again I'm not fully on board on this. First differentiation makes me think of consumer product features.
To points above this is what they are. So as a module seller they equipped with their common HP wafer ,build on vanilla cells, will not be part imho of the revolution, which I expect to see in few years. Not on the dynamic of today.Yes, I believe that SOL's value is primarily as a wafer maker (having in-house super low cost poly).
I am not sure how you do it. The only way I could think of calculating this would be to know total shipment and measure amount of physical modules shipped. This could be possible, but it is certainly not disclosed. If you looking at the datasheets, I am skeptical this has value. I could assume that Panda shipments are 270s based on recent specs and Honey ships in 260s. To conclude, high efficiency modules cost more per watt, agreed? Therefore why sum of watts sold by Renesola commands such a low ASP? They export all of it, so overseas ASP would be beneficial. Is the brand, sale channels etc? Perhaps but those are the factors I described. Hanwha has a good brand name. Certainly a lot more after Q.Cells buy. They sell at the same price. Interesting why this is . Certainly feeling on their modules is they are low efficiency, for now.I look at the product specs of their volume products. For most of these Chinese companies these are the standard 60 and 72 multi cell products.

This is my suspicion also.My assumption (confirmed by examples I've seen) is that the distribution curve for power yield in module production is bell shaped. So when product sheets show a range of powers available I assume that the average is the mid-point (as it is for normal distributions).
Sunday, January 13th 2013, 2:19pm
I agree with eystein, that's would be very valuable data. Once you've identified type of module (e.g. 6x60 or 6x72) and number of modules and the total watts for a container the actual average conversion efficiency of exported modules would be visible. Right now I'm just basing numbers on plausibility using normal distribution assumptions. I think the current simple and assumed model still has decent enough confidence to place the weight I do on it in stock pick evaluations.Explo. certainly this is the case of brand building and has a promotional aspect attached to it.
Accepting explanation, I am not convinced with the perception that particular module rating is responsible or present in ones modules sales. We do not have this visibility. I think however that it is possible to extract it from module shipment data. The only needed ingredient is the physical account of the shipment, like containers, pallets. I contacted Jason for some info on this. By understanding this average for various destinations, you can average company's efficiency for overall shipment number and build a better understanding of efficiency in its capacities. View we do not have today. Yet I am getting ahead of myself, may not be possible or have too many variables to compile. I will have to wait for his response.
