WUXI, China, July 22, 2013

WUXI, China, July 22, 2013 /PRNewswire/-- Suntech Power Holdings Co., Ltd.
(NYSE: STP) ("Suntech Holdings" or the "Company"), one of the world's largest
solar companies, today announced that it is supplying the photovoltaic modules
for the largest solar power plant in Latin America, a 30MW plant in La Paz,
Baja California Sur, Mexico.

The 132,000 Suntech Ve and Vd panels will be installed by Martifer Solar, a
Portugal-based fully-integrated solar company, on a 100-hectares site. Owned
by Corporacion Aura Solar, the project is being developed by Gauss Energia, a
leading Mexican energy project developer focused on renewable energy.

The project has strong financial support from Mexican local development bank
NAFIN, and from the International Finance Corporation. It is Mexico's first
utility-scale solar project with a Power Purchase Agreement from Mexico's
federal power company.

E.L. McDaniel, Managing Director of Suntech America, said, "We are very
excited to supply the panels for the largest solar field in Latin America.
With Mexico's excellent sunlight and strong renewable energy demand, we expect
to see excellent growth of PV in the region."

Henrique Rodrigues, CEO of Martifer Solar, said, "The construction of Latin
America's largest PV plant confirms our best expectations for 2013. This is an
emblematic project for Martifer Solar, in a region that, due to its
irradiation characteristics, finds solar electricity as a viable and more
competitive alternative, when compared with non-renewable energy sources. We
consider Mexico as a key market in Martifer Solar's internationalization

Hector Olea, CEO of Gauss Energia, said, "Aura Solar is the first project of a
larger initiative that aims to become a platform to develop utility-scale PV
facilities in Mexico. With Mexico's solar potential expected to reach around
2,000 MW by 2020, Aura Solar has broken ground in the PV sector, and it is
paving the way for future projects in the field. We are quite satisfied to
have worked with Suntech and Martifer on this project."

The plant will have a production capacity of 82 GWh/year, equivalent to
offsetting more than 60,000 tons of CO[2] emissions per year. The plant's
construction is scheduled to be completed in August 2013.
