China Sunergy Delivers First Quasar Shipments to Sunergic S.A.

NANJING, China, October 21, 2011 -

China Sunergy Co., Ltd. (Nasdaq: CSUN) (”China Sunergy” or “The Company”), a specialized solar cell and module manufacturer, today announced that it had delivered its first commercial Quasar module shipments to Switzerland’s Sunergic S.A..

Under the agreement, China Sunergy has delivered in October 0.30MW of the Quasar modules to Sunergic, which is located in the Vevey area and is one of the leading solar distributors in Switzerland.  Quasar modules are China Sunergy’s most advanced high efficiency solar products, and they are now undergoing TÜV Rheinland and UL (Underwriters Laboratories) safety and quality product certifications.  The modules are being launched on a trial basis exclusively to long-term customers to test market reactions.  China Sunergy has previously supplied solar modules to Sunergic S.A. and already has a good relationship with the company.

“We are pleased to see the Quasar module advancing into commercial production and sales, and with good value for the price, this sale demonstrates that Quasar products have huge potential to become a key profit driver for CSUN in the future.  It’s great to be working with one of our key existing customers to introduce this new leading edge product,” said Stephen Cai, CEO of China Sunergy.

Nico Lugt, Sunergic’s CEO said, “Clearly, it’s in the best interest of solar developers to buy modules that generate more electricity in the same amount of space, especially in Switzerland, because surface is rather limited and manpower for installation is expensive.  We are willing to buy dependable, extra efficient modules at a premium because they give us a competitive advantage over other distributors in Switzerland.  Having China Sunergy as a long term partner, we look forward to more exciting projects in the near future.”
