Hoku Solar Inc. said it has signed a definitive agreement to install a photovoltaic power system at Paradise Beverages' O'ahu facility.

Hoku Solar, a unit of Kapolei-based Hoku Scientific Inc., has already completed the installation of two photovoltaic power systems for Paradise Beverages at its facilities in Kailua, Kona and Lihu'e.

Paradise Beverages is the Hawai'i 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 O'ahu facility installation, the aggregate of all three photovoltaic power systems for Paradise Beverages will include 350 kilowatts of photovoltaic panels, which are expected to produce more than 525,000 kilowatt-hours of electricity each year.

"The benefits of our PV power system installations on our Kailua, Kona and Lihu'e facilities were immediate. This made our decision for an installation on our O'ahu facility with Hoku Solar an easy one," said Gordon Usui, chief financial officer for Paradise Beverages.
