SAN FRANCISCO, Jan. 14, 2013

SAN FRANCISCO, Jan. 14, 2013 /PRNewswire/ -- ReneSola Ltd ("ReneSola") (NYSE:
SOL), a leading global manufacturer of solar photovoltaic ("PV") modules and
wafers, today announced that the Company's 60- and 72-cell polysilicon and
monosilicon solar modules exceeded the Company's power output guidelines when
assessed by a recent third-party flash test.

In December, Spire Corporation ("Spire"), a leading global provider of capital
equipment used in the manufacturing and testing of PV modules and cells,
invited ReneSola to participate in a demonstration of the Spire Spi-Sun
Simulatorâ„¢ 5600SLP flash tester, which exposes the modules to a single
long-pulse flash of filtered xenon light to approximate solar irradiation.
Four ReneSola modules were tested, all of which produced a maximum power
output greater than that indicated on the Company's datasheets, by as much as
eight watts. The test results confirmed that ReneSola's modules perform at
least as well as the nominal power outputs and efficiencies stated on the
Company's datasheets.

"Spire has set the industry standard in more ways than one, which is why we
were confident the results of this demo would exceed expectations and support
ReneSola's claim that our modules are among the most efficient in today's
solar PV marketplace," said Kevin Chen, president of ReneSola America. "We
can't emphasize enough the importance of independent testing in identifying
top performers in the crowded market for solar products and solutions. Many of
our customers also ask to perform their own tests on our modules, which is
something we certainly encourage."

"ReneSola has done a remarkable job increasing and improving module
efficiencies with its wafer technology, an innovative approach considering
others are focused on improving efficiencies through cell technology," said
Steve Hogan, executive vice president and general manager of Spire Solar. "We
were thrilled to see ReneSola's technology on the 5600SLP. Spire's 5600SLP is
the latest in Spire's metrology tool set, and its extended pulse length and
Class A+ (in spectrum, spatial uniformity, and light stability) classification
allows for more accurate measurements of advanced technologies such as those
held by ReneSola. The results were favorable and we are pleased to have been
able to work with ReneSola to demonstrate their performance claims, and prove
Spire's tool capabilities for customers to not sell short their module watts."

The flash tester used in the demonstration was calibrated with a National
Renewable Energy Laboratory ("NREL") tested and certified module immediately
before the testing of ReneSola's modules. The 5600SLP is the latest and most
accurate and repeatable PV module measurement technology available in its
class and joins Spire's simulator product line commonly used by the NREL,
Underwriters Laboratories, TUV Rheinland Group, Intertek, and the Florida
Solar Energy Center.
