SHELTON, CONNECTICUT and TORONTO, ONTARIO--(Marketwire - Sept. 3, 2008) -
OPEL International Inc. (TSX VENTURE:OPL) ("OPEL" or "the Company"), a
leading global developer and supplier of high concentration photovoltaic
(HCPV) and other solar products, today announced that testing of its Mk-I
HCPV solar panel verified that it qualifies under the provisions of the IEC
62108 standard. With the achievement of this milestone, OPEL has positioned
itself to be a leading supplier of HCPV panels in the important European
market and beyond.

OPEL's Mk-I will now ship bearing the CE label indicating compliance with
European market requirements, meeting the quality standard for PV products
and other solar equipment in European markets. The CE certification of
OPEL's Mk-I product will allow OPEL's customers to apply for permits and
feed-in-tariff contracts, thereby accelerating the deployment of their
planned installations.

In addition, with CE qualification completed, a number of market
opportunities are now open for OPEL's Mk-I HCPV panels in other markets
that use European standards as guidelines for their own installations.

"With this CE Qualification, we have achieved a very ambitious milestone
that we set for ourselves earlier in the year, and done so ahead of
schedule," said Dr Javier Berrios, OPEL's Vice President of Engineering. "I
can't be more pleased with our Qualification and the performance of the
high efficiency Mk-I HCPV panel. Most importantly, our customers in Europe,
Asia and the Mid-East will now receive Mk-I HCPV panels with CE labels for
their applications."

The Mk-I concentrates light more than 600 times and has one of the highest
efficiencies of concentrators in commercial production today. The Mk-I was
shipped to customers in the Czech Republic, France, Spain, Korea and the
United States, for large scale solar grid field applications.
