RSi Unveils SuperPV: The World`s Most Powerful Commercial Solar Module at Inter-Solar 2009 (Munich)

MUNICH--(Business Wire)--
Rainbow Solar Inc. (RSi), the innovative clean energy company that introduced
the world`s first transparent PV window announces the SuperPV: a breakthrough
technology that increases the power generation of silicon solar cells by 60 -
200%.

This extraordinary gain in power output has been confirmed by Osaka University`s
Center for Advanced Science and Innovation (CASI). "To the best of my
knowledge," reported Dr. Shozo Yanagida - Japan`s leading photovoltaic
scientist, "the SuperPV is the only technology to have produced such results."

As we approach the physical limits of silicon-based photovoltaic (PV)
technology, even a 3% output gain has become extremely difficult to achieve.
ThinFilm PV is even less efficient. The 60%+ power-generation increase made
possible by the SuperPV is nothing short of revolutionary, "a milestone in solar
technology".

Under low-light conditions, SuperPV modules consistently generate a much more
constant electrical output regardless of sunlight fluctuation and drop-offs than
identical modules not equipped with the SuperPV. During peak sun periods, the
SuperPV consistently generated power above sunlight levels.

California Summary days can stop power-generation on conventional solar panels
caused by over-heating. CASI observed a phenomenon that SuperPV cause a
`cooling-effect` on the module, where the SuperPV recorded "astonishing" results
of more than 200% power-output gain under strong sunlight conditions.

"Given its substantial benefits and broad compatibility, I expect that the
SuperPV will become an integral component of all future photovoltaic modules,"
predicts Professor Yanagida.

The implications of the SuperPV are enormous for the entire energy industry,
beyond grid-tied applications: the SuperPV-BIPV can lead to self-powered
buildings with utility class of solar energy, introduced at the ICSC Recon event
in Las Vegas on May 18, 2009.

"Speaking also, as a special guest in both presentations…RSi Solar gave a
stunning overview related to Solar Windows and SuperPV breakthrough technology.
Representative of the accelerating advances in the Solar Industry, Pierce
presented some compelling statistics demonstrating what could only be considered
as aquantum leap in solar efficiency and overall viability." - Timothy Boe, AIA
