GT Solar Signs $8.8 Million Contract with Nexolon Co., Ltd.

GT Solar Incorporated, a key global provider of a comprehensive range of

equipment, services and technology solutions to the solar power

industry, announced today that it has entered into a contract to supply

Nexolon Co., Ltd. of South Korea with DSS450 furnaces and accessories

worth approximately $8.8 million (US). Deliveries are expected to be

made over the next 5 months.
The DSS450 (Directional Solidification System) model furnace is GT Solar´s

newest and most technically advanced furnace. The furnace enables solar

panel producers to "grow" multi-crystalline silicon ingots, which are processed into wafers and

converted into solar cells which produce electricity when exposed to

sunlight. Multi-crystalline wafers are a core component used in the

production of solar panels worldwide. GT Solar´s

latest technology DSS450 furnace allows producers to increase their

silicon ingot output by approximately 30% over previous furnace designs.

Ingots produced annually from a DSS450 furnace are capable of providing

enough electricity to power up to 1,000 average U.S. homes for one year.
GT Solar began shipments of its DSS line of furnaces in 2003.
"This represents GT Solar´s

first DSS contract in South Korea, and we look forward to helping our

new customer, Nexolon, develop its business and become a key player in

the production of multi-crystalline ingots," said GT Solar CEO and President, Tom Zarrella. "This

contract is yet another example of GT Solar´s

key role in providing technology worldwide to meet the demand for solar

energy."
Nexolon CEO Woo-Jeong Lee, noted: "We are

delighted to have the opportunity to work with GT Solar as we start to

build our business to meet solar energy demands in South Korea. We

believe GT Solar has the resources and know-how to assist us as we move

forward."
