Perpetual Power Completes 1-MW Solar-Powered Water Pumping Systems

Mitsubishi Electric & Electronics USA Inc. and Perpetual Power (P2) have completed the installation of four solar-powered deep water wells at Limoneira Company’s Ducor Ranch in California. The four 250-kilowatt (kW) solar arrays that make up the proejct include single-axis tracking systems which are expected increase power output of each array by 15%.

When operating at full capacity, the 6,400 ground-mounted, high-efficiency photovoltaic panels can generate 1-megawatt (MW) of energy for the Limoneira Company, which grows and processes lemons, avocados, oranges, specialty citrus, pistachios and cherries on its orchards in Santa Paula, California Limoneira’s solar electric system is expected to produce 2.3 million kilowatt-hours (kWh) of electricity annually, P2 said.

The four 250-kW solar systems replace fossil fueled-powered water pumps. This new 1-MW system complements Limoneira’s existing 1 MW solar orchard installed in October 2008, supplying the company with a total of 2 MW of solar power.

The solar system is owned by a third-party company, which allows Limoneira Company to purchase the electricity for an average of $0.08/kWh, more than a third less than California’s average retail electric rate of $0.12/kWh.
