AstroPower Powers Up World's Largest Hybrid-Solar/Wind Power System

Solar Cells Provide Clean Electricity for Water Pumping at Ranch on the Big

Island of Hawaii



Apr 25, 2001, 01:00 ET from AstroPower, Inc.

    NEWARK, Del., April 25 /PRNewswire/ -- AstroPower, Inc. (Nasdaq: APWR)
 (www.astropower.com) announced today that its solar electric power cells and
 large-area panels are at the heart of the world's largest hybrid-solar/wind
 power system, now operational in Kamuela, Hawaii.  Located on the Big Island,
 this 225-kWac solar/wind power hybrid system generates electricity 24 hours
 per day to meet the water-pumping demands of Parker Ranch, one of the largest
 cattle ranches in the United States.
     The installation features a 175-kWac solar electric power system, designed
 and installed by PowerLight Corporation (www.powerlight.com).  The system
 incorporates approximately 80,000 AstroPower solar cells in more than 475
 AstroPower Large-Area Panels.  Rated at 440 Wp each, AstroPower's Large-Area
 Panels are the largest UL-approved solar power panels commercially available.
     Using PowerLight's PowerTracker, the solar arrays automatically track the
 sun throughout the course of a day.  After the sun sets, the Parker Ranch
 system relies on five wind turbines to contribute 50 kW of power.
     The 225,000-acre cattle ranch, located on Hawaii's Waimean pasturelands,
 uses this renewable energy produced at the point-of-use to operate pumps that
 deliver drinking water to livestock in three grazing areas.  Savings in
 electric utility bills more than cover the amortized cost of the hybrid
 system.
     Solar and wind power are complementary technologies used increasingly in
 hybrid systems to provide reliable and cost-effective electricity at point-of-
 use.  Solar power typically coincides closely with peaking demand, and wind
 often fills in the gaps by generating at night and during inclement weather.
     "We're pleased to play such a major role in the world's largest hybrid
 solar/wind power system," said Howard Wenger, AstroPower's Vice President,
 Premium Power Business.  "Our Large-Area Panels really deliver for Parker
 Ranch, ensuring reliable electricity generation and conservation
 simultaneously."
