NANJING, China, May 5, 2011 - China Sunergy Co., Ltd. (Nasdaq: CSUN) ("China Sunergy" or "The
Company"), a specialized solar cell and module manufacturer, today announced
that the Company has been awarded a Certificate under the UK Microgeneration
Certification Scheme issued by BABT (British Approvals Board for
Telecommunications) for its modules. BABT is an accredited MCS certification
body and one of the world's leading certification bodies, whose global brand
is widely respected. The certificate, which is valid through April 24, 2014,
authorizes CSUN photovoltaic solar panels to be sold with the MCS approved
product mark.

With this MCS certificate, China Sunergy is in a better position
to expand in the U.K. market, further diversify its customer base and build
up brand recognition for its solar module products. The concept behind the
MCS certificate is to reduce the UK's reliance on fossil fuels and reduce its
carbon dioxide emissions. MCS underpins government policies on low carbon and
renewable onsite energy technologies and supports the UK's overall effort in
meeting EU 2020 Renewable Obligations targets.

Mr. Stephen Cai, the Chief Executive Officer of CSUN, commented,
"We are very pleased with this news. This is not only a recognition of our
product quality, but also a great opportunity for CSUN to step into the UK,
an emerging yet strategically important market for our solar products."
