China Sunergy, a solar cell manufacturer, has signed an agreement with Germany-based Aleo Solar to supply 30MW of high-quality silicon solar cells.

China Sunergy will supply 10MW of solar cells to Aleo during the first half of 2008, and deliver the additional 20MW during the second half of the year. The company also owns an option to buy an additional 10MW from China Sunergy in 2008.

In addition to the supply agreement in 2008, both parties have agreed to explore a longer-term business relationship extending into 2009. Details of the longer-term relationship will be negotiated by June next year.

The average conversion efficiency of the solar cells China Sunergy will supply should be no less than 16%, according to the terms of the agreement.
