Opportunities in turbulent PV equipment market

December 19, 2012 1 comment

Ms. Fatima Toor, analyst, Lux Research, recently presented on opportunities in turbulent PV equipment market, in association with SEMI, USA.

Global PV market trends
Bankruptcies are galore. Eg. Solyndra, Abound Solar, Konarka, etc. Global trade wars are also on the rise. There are US tariffs on Chinese solar cells. There is also an EU investigation on Chinese solar panels. Then, there are Chinese investigations on US, EU and Korean polysilicon dumping. Government incentives have been lowered in the EU, but raised in Asia and Americas. Following Barack Obama’s re-election in the US, the environmentalists are again upbeat about green energy.

Crystalline Si remains dominant.

Crystalline Si remains dominant.

Global PV demand increase will be driven by Asia and Americas in the coming years. Emerging markets will grow over six times in size from 2011-2017. Crystalline Si will be the dominant installed PV technology, at least till 2017. Gap between demand and supply will close.

The Q3-12 geographical capacity distribution would be across PV value chain. China leads in polysilicon, cells and modules supply. Chinese equipment manufacturers market share has been on the rise, ramping up competition for Western equipment suppliers.

Lux Research sampled 493 PV manufacturers. Of these, 40 percent are based in the EU, 28 percent are based in China, 17 percent are in the US and 15 percent are in the Rest of the World.

Opportunities for equipment manufacturers in current market state
Cost, efficiency and price are fundamental drivers of PV industry. Innovations across the value chain will enable higher margins for PV industry. The desire for cell and module manufacturers to reduce costs and differentiate will drive opportunities for equipment manufacturers.

Crystalline Si technology: Innovations across crystalline Si value chain would enable opportunities for equipment suppliers. Fluidized bed reactor (FBR) process requires 10 lWh/kg and is a continuous process. Why is FBR only 6 percent of total polysilicon capacity today? The reasons are:
* No off-the-shelf FBR reactors are available.
* Process complexity requires that Si granules can be polluted by impurities.
* There is an opportunity for equipment manufacturers to develop off-the-shelf FBR equipment that will enable reduced production costs for polysilicon.
* GCL announced developing its FBR technology.
* Samsung Fine Chemicals and MEMC have partnered to set up FBR polysilicon production due to its lower production costs.

Monocrystalline silicon (c-Si) ingot growth using Czochralski (CZ) method is high cost and results in pseudo-square c-Si wafers. Plate seed for qc-Si ingot growth with mc-Si grains on the edges and c-Si in the middle. ReneSola has technology with wafer capacity of 2GW of which 1.6GW is qc-Si Virtus wafers and 0.4GW are c-Si wafers. ReneSola is likely to be one of the Chinese companies to survive the shakeout due to its strategy and technology.

Opportunities exist to optimize qc-Si ingot growth. Modified directional solidification (DS) furnace makers claim 90 percent c-Si and 10 percent mc-Si yields during qc-Si ingot growth. In reality, 60 percent c-Si and 40 percent mc-Si results in high wafer binning and sorting costs. This provides an opp for equipment manufacturers to improve the c-Si yield to higher than 90 percent. The Qc-Si capacity is likely to increase in the coming years as DS furnace manufacturers innovate.

ReneSola intros Virtus II PV modules in India

Virtus II modules from ReneSola.

Virtus II modules from ReneSola.

ReneSola Ltd, a leading global manufacturer of solar PV modules and wafers, has introduced its new Virtus II multicrystalline modules in India. ReneSola has started providing locally produced PV modules to the Indian market and expects to provide 250 MW of India-made PV modules over a two-year period.

The India launch follows the successful introduction of the Virtus II solar modules to the US and Australian markets.

Founded in 2005, Renesola has 17 subsidiaries worldwide. Production sites located in Zhejiang, Jiangsu and Sichuan, China. The supplier estimates to ship 1,550 ingots and 700 wafers during 2012, up from 1,014.1 ingots and 295,2 million wafers in 2011.

Some of Renesola’s projects include 4MW and 2MW in Slovakia, 11.5MW in Germany, 20MW in China, 9.21MW in Italy, and 27.6MW again in Germany. A couple of Renesola’s rooftop projects include 118.8KW in Slovakia, 1.95MW and 100.8KW in Greece, 1.4MW in Belgium, 12.96KW in Bulgaria, and 806.4KW in Germany.

Virtus II modules
Characteristics of the Virtus II modules include higher power output, higher performance at same cost, same LID, and same CTM cost. Virtus ingot improves the distribution of grain size and lifetime, and provides higher lifetime and lower dislocation density. The Virtus A++ wafer allows uniform grain distribution with less defects. The Virtus A++ wafer also has much lower defects.

Major defects of conventional multi‐crystalline wafers can be reduced by the innovative controlled DSS method. The Virtus I module provides better temperature coefficient of power and lower light induced degradation compared to mono modules. The Virtus II wafer increases cell efficiency due to higher lifetime, lower dislocation and uniform grain size. The Virtus II module shows better performance and the same production cost of multi-module.
