Hoku Solar Enters Into New Contract With Hawaii's Heineken, Coors and Miller Beer Distributor

KAPOLEI, HI--(Marketwire - March 24, 2008) - Hoku Solar, Inc., a wholly owned subsidiary of Hoku Scientific, Inc. (NASDAQ: HOKU), established to design, engineer and install photovoltaic (PV) power systems, today announced that it has signed a definitive agreement with Paradise Beverages, Inc. to install a PV power system at its Oahu facility. Hoku Solar had previously completed the installation of two turnkey PV power systems for Paradise Beverages at its Kailua-Kona, on the Big Island of Hawaii, and Lihue, Kauai, facilities.

Paradise Beverages is the Hawaii distributor for Heineken, Coors and Miller products, and it consumes a significant amount of electricity to operate its refrigerated and temperature-controlled warehouses. Upon completion of the Oahu facility installation, the aggregate of all three PV power systems for Paradise Beverages includes 350 kilowatts of PV panels, which are expected to produce over 525,000 kilowatt-hours of electricity each year.

"The benefits of our PV power system installations on our Kailua-Kona and Lihue facilities were immediate. This made our decision for an installation on our Oahu facility with Hoku Solar an easy one," said Gordon Usui, Chief Financial Officer for Paradise Beverages.

PV systems are a sensible way to utilize unused roof space to reduce energy costs and environmental impact. Hoku Solar offers turnkey PV solutions in Hawaii, providing design, engineering, financing, and installation services.
