Le Chinois SUNTECH à mis au point des lingots de Silicium qui sont mixte Si monocristallin au mileu et polycristallin sur les bords ! Et ca a cout quasiment identique au polycristallin. Ca permet de gagner un peu en rendement de cellule (par rapport un a tout polycristallin).

C 'est original.
Du coup les cellules du panneau présentent deux aspects différents. Pas trés esthétique je trouve.
Cheaper High-Efficiency Solar Panels
Suntech Power has developed a better way to make high-grade silicon wafers.


Chinese solar-panel manufacturer Suntech Power has developed a new process for making silicon wafers for solar cells that could cut the cost of solar power by 10 to 20 percent.

The most efficient silicon solar cells use wafers consisting of a single crystal of silicon. When made by the new process, these high-quality "monocrystalline" wafers cost about the same as lower-quality multicrystalline wafers, or potentially half as much as monocrystalline wafers made by conventional processes. (Wafer cost is only part of the cost of solar power, which is why a process that may cost half as much only reduces the overall cost by 10 to 20 percent.)

The idea underlying the process was patented more than 20 years ago but never commercially developed by the patent owners. The patents expired about three years ago, and several companies—JA Solar, LDK Solar, and Renesola, in addition to Suntech—recently announced that they had succeeded in making the process work.

Les capacité de production de Silicium pour le photovoltaique augmentent incroyablement en Asie.
Quasi un facteur 2 cette année ! --> Chute des prix.
Asia Doubles Solar Silicon Factories, Pursuing Gain in Slump

July 11 (Bloomberg) -- Asia's largest makers of silicon for solar panels are almost doubling their factory size this year just as surplus production sends prices tumbling for the main raw material for the $35 billion industry.

Korea's OCI Co. and GCL-Poly Energy Holdings Ltd. of China said they'll increase capacity to a combined 88,000 metric tons a year from 48,000 tons. Global demand for the material, known as polysilicon, is growing at less than a third of that rate, and spot prices fell 32 percent in the second quarter, Bloomberg New Energy Finance estimated.

Asians are deploying equipment to refine silicon crystals more quickly than Western competitors. They anticipate gaining share from the world's largest suppliers, Hemlock Semiconductor Corp. of the U.S. and Germany's Wacker Chemie AG, as customers increasingly demand lower prices for the key material used in panels to convert sunlight into electricity.
.....

Solar-grade silicon fell to $53.40 a kilogram ($24.27 a pound) in June, the lowest in more than six years, from $78.90 in March, according to the London-based research company. The material, which cost as much as $450 a kilogram in mid-2008, may sell for $40 to $50 for the rest of 2011, said Jenny Chase, New Energy Finance's chief solar analyst.

Le norvégien REC va supprimer 700 emplois dans le solaire

Renewable Energy Corporation (REC), le fabricant norvégien de polysilicium dans le secteur photovoltaïque a annoncé hier la fermeture définitive d'une partie de sa production en Norvège après des résultats trimestriels très décevants.
REC indique que la fermeture de ses usines produisant des wafers et des cellules solaires se traduira par la suppression d'environ 17% de ses effectifs, soit environ 700 emplois sur les 4.000 employés du groupe.

...............

La part de marché du couple infernal Chine + Taïwan dans la production de cellules photovoltaïques n'a cessé de grimper, passant de 19% à 59% en 5 ans (2006 à 2010). L'Europe et le Japon demeurent les grands perdants de cette concurrence effrénée

La société Allemande Centrotherm Photovoltaics à signée un accord géant en Arabie Saoudite pour la construction d' une usine de fabrication de cellules solaire PV polysilicium d' une capacité de 6000 tonnes par an, à YANBU.
On parle d'un projet à 1.1 milliard de $ !
German-Saudi partnership to build solar facility

February 12, 2012

Germany’s Centrotherm Photovoltaics, the world’s second-largest manufacturer of solar photovoltaic (PV) equipment, has signed an agreement with IDEA Polysilicon to construct a polysilicon solar PV manufacturing facility in the Saudi Arabian Red Coast city of Yanbu, it was reported on 7 February.

The agreement aims to provide IDEA the technology and know-how it needs to become a market force in the Middle East-North Africa (MENA) region, a market that’s attracting more and more interest from industry players globally. The value of the contract wasn’t disclosed, though the project’s anticipated cost is more than $1.1bn.

Created by a group of Arabian Gulf investors, IDEA Polysilicon’s polysilicon plant will be the first in the Middle East. Planned capacity is 6,000 tonnes per year of high-quality polysilicon, according to the company. Revenue generated by Centrotherm’s Solar Cell & Module unit leapt 85.1% to €546.5mn and operating earnings, as measured by EBIT (Earnings Before Interest and Taxes), leapt 70.2% to €102.3mn in the first nine months of fiscal 2011, management reported in November.

Coûts du solaire (différentes techniques confondues)

Message par energy_isere » 26 oct. 2021, 23:59

Le cout du solaire repart franchement à la hausse en suivant les matières premières employées en particulier le Silicium Polycristallin:
Major Cost Increase Threatens Solar Power In 2022

By Rystad Energy - Oct 26, 2021

The surging cost of manufacturing materials and shipping could threaten 50 gigawatts (GW) – a staggering 56% – of the 90 GW of global utility PV developments planned for 2022, a Rystad Energy analysis shows. Commodity price inflation and supply chain bottlenecks could lead to the postponement or even cancelation of some of these projects, impacting demand and consumer pricing for solar-generated power.

Driven by core component price inflation, manufacturing costs for PV modules have surged from below $0.20 per watt peak (Wp) in 2020 to between $0.26 and $0.28 per Wp in the second half of 2021 – a near 50% increase in a year.

A significant driver of this surge is a more than 300% hike in the cost of polysilicon, a core component in PV manufacturing. In addition, other raw materials – silver, copper, aluminum and glass – have also climbed steadily since January 2020, increasing the pressure on module prices.

"The utility solar industry is facing one of its toughest challenges just days ahead of COP26. The current bottlenecks are not expected to be relieved within the next 12 months, meaning developers and offtakers will have to decide whether to reduce their margins, delay projects or increase offtake prices to get projects to financial close," says David Dixon, senior renewables analyst at Rystad Energy.

Image

In addition to materials cost inflation, shipping is another element in the supply chain causing considerable challenges for developers and module suppliers. The cost of shipping continues to rise, playing more of a role in overall production capital expenditure. Before 2021, the cost of PV shipping had a minimal impact on the overall production cost. However, pandemic-era shipping delays and bottlenecks have resulted in a near 500% increase in prices, from $0.005 per Wp in September 2019 to $0.03 per Wp in October 2021.

Modules and their associated shipping costs typically comprise between a quarter and a third of the total project capex and together represent the single-largest item of a project's cost. When the cost of modules – and shipping – increases, it can significantly impact project economics.

Rystad Energy performed a sensitivity analysis to determine the levelized cost of electricity (LCOE) for different plant sizes comparing last year’s module and shipping costs with current costs. The results show that the LCOE of new projects has increased by between 10% and 15%, a major cost bump for most of the projects planned for 2022. Seeing their projects at risk, developers may have to resort to negotiating higher power purchase agreements (PPA) or absorbing some of the cost inflation, accepting higher project costs and lower margins.

Le PolySilicium pour cellules solaires atteint $45.47/kg.
Polysilicon price relief in 2023 as industry scales to 500 GW
Clean Energy Associates says solar wafer pricing will fall by 23% by the end of 2023, while BloombergNEF sees 500 GW of manufacturing capacity online by the end of next year.

AUGUST 31, 2022 JOHN FITZGERALD WEAVER

The China Nonferrous Metals Industry Association said last week that polysilicon prices touched $45.47/kg, before settling a bit lower. This is an increase of more than 600% from the low pricing of under $7/kg seen in the second quarter of 2020.

It takes about 3 grams of raw polysilicon to create each watt of a solar panel, so a 400 W residential solar panel uses 1.2 kg of polysilicon. The largest panels – 700 W utility-scale modules – use 2.1 kg. The 700 W utility-scale panel contains $90 of polysilicon.

Spot market prices are likely much higher than the prices being paid in long-term contracts. The cost of polysilicon inputs hasn’t risen nearly to the same heights, so companies that produce their own polysilicon are actually paying much less for their input costs. Multiple parties have suggested that the industry should see significant volumes of polysilicon manufacturing come online as the year ends, which would lead to decreases in pricing starting in 2023.

Clean Energy Associates (CEA), in its PV Price Forecasting Program Q2 2022 report, said “significant expansions among ingot and wafer suppliers are expected to create a competitive market scene when these suppliers can once again source lower-priced polysilicon.” It said that by the end of 2022, the world will have approximately 285 GW of polysilicon manufacturing capacity online.

While the executive preview version of the report does not share future polysilicon pricing, CEA does suggest that the average 2022 wafer pricing of $0.13/W could fall by as much as 23% by the end of 2023. This implies that polysilicon pricing could fall by roughly $10 per kg. BloombergNEF recently suggested that by the end of 2023, there will be enough polysilicon manufacturing facilities to supply 500 GW of solar modules.

Prévision de baisse des prix importante sur le polysilicium pour le solaire PV en Chine.

PV InfoLink forecasts polysilicon prices to be halved by end of 2023
The consulting firm expects prices to decline gradually through the first semester of 2023, followed by an accelerated decline in the second half of the year, with prices falling from the current CNY 300 ($36.64)/kg to below CNY 150/kg by the end of 2023. Polysilicon production capacity may increase from 500 GW in 2022 to 975 GW next year.

OCTOBER 25, 2022 BEATRIZ SANTOS

PV Infolink forecasts polysilicon prices to decrease from around CNY 300 ($36.64, excluding VAT)/kg currently to below CNY 150/kg by the end of 2023, it revealed in a joint webinar with analysts Exawatt and Roth Capital Partners.

Prices are expected to decline gradually in the first half of 2023 and then see a steep decline in the second half of the year. The consulting firm expects polysilicon production capacity to increase from 293 GW earlier this year to around 500 GW by the end of 2022, spiking to 975 GW by the end of 2023. However, “there will likely be a meaningful lag between nameplate and effective capacity,” a company statement reads.

China is likely to remain the world’s largest polysilicon producer for the foreseeable future, with both PV Infolink and Exawatt predicting non-China polysilicon to represent up to 10% of total global capacity. Following the Uyghur Forced Labor Prevention Act (UFLPA) in the US, the country is expected to increase polysilicon production. Other countries are also ramping up or starting production, including Norway, Turkey, and Germany. Both firms expect prices for polysilicon from outside of China to be higher by between 5% and 10%.

PV Infolink predicts that it will take between two to three years of operation for new entrants to be competitive with established players like Chinese manufacturers in terms of capacity, yield rate, and purity.

Cell, wafer, and module prices are also predicted to decrease. PV Infolink expects cell pricing to be roughly $0.16/W through 2022 and fall slowly next year to around $0.10/W by year-end. It puts current pricing for a 210 mm mono wafer at around $0.21/W, which could fall to around $0.13/W by end 2023. Module pricing may fall slightly to between $0.22 to $0.23/W at the end of 2023 from the current $0.25 to $0.27.
