Munich, Germany: Centrosolar and Qimonda in Cell Manufacture Joint Venture

CENTROSOLAR Group AG and Qimonda AG have entered into a venture for the production of crystalline solar cells. The production plant will be established near Porto (Portugal) next to the existing semiconductor factory of Qimonda. Initially, the production plant will have a capacity of approx. 100 MWp by the end of 2009 and will provide jobs for roughly 150 employees.

The sourcing of multi-crystalline silicon wafers has been secured for this first stage of the venture. The venture company will invest approx. EUR 70 million until September 2009.

Approximately 70% of the financing is expected to be provided by local banks. In addition, the partners plan to apply for a funding package provided by Portuguese state authorities in accordance with European funding regulations, for which the first indications appear to be advantageous.

CENTROSOLAR accounts for 49% of the equity of the venture company and will thus receive 49% of the production output. CENTROSOLAR is refinancing its equity share by a 10% capital increase via a private placement. The placement is backed by a guarantee from a major shareholder.

Qimonda is investing 51% and will market its corresponding share of the production output. This source of crystalline solar cells covers 25% (approx. 50 MWp) of CENTROSOLAR’s annual module production capacity (195 MWp in 2010) at much more favourable terms than comparable long-term contracts from cell manufacturers.

While securing the base load for the company’s growing project business, CENTROSOLAR remains flexible in its cell sourcing strategy for its integrated solar systems business for private homes. CENTROSOLAR thus will expand its business with its existing cell suppliers, and also plans further expansions of the venture company to feed its accelerated growth in the future.

The venture company will use the crystalline silicon technology leveraging the in-depth expertise of Qimonda in all relevant processing steps. After the ramp up phase, the solar cells will provide an electrical efficiency of more than 16%. The improvement of cell efficiency will become the key lever to reduce total system costs.

With its strong R&D backbone, and its comprehensive experience in high-quality and cost-efficient mass production, Qimonda is in a very competitive position to drive and implement efficiency improvements faster than traditional cell manufacturers. Qimonda is also leveraging its experience with silicon suppliers as well as the availability of waste silicon from its DRAM operations to set up supply contracts with attractive terms.

Silicon supply for the initial capacity has been secured with wafers from LDK. The venture company will receive a total of 540 MWp solar wafers over 5 years from the leading Chinese manufacturer LDK Solar Co. Ltd, whose customers include several global and renowned solar cell manufacturers. The signed agreement furthermore allows LDK to receive scrap silicon material from Qimonda's chip production operations.

The prices are initially fixed for each year, but do incorporate a flexible component to reflect the general market price trend from 2011 onwards.

Since CENTROSOLAR has the right to purchase its allocation of cells on a “cost plus” basis, CENTROSOLAR will be able to purchase significantly below the price levels of the typical long-term supply contracts offered in the industry.
