Perpetual Power has completed the design and installation of four solar-powered deep-water wells at Limoneira’s Ducor Ranch in California’s Tulare Country. The quartet of 250kW (AC) solar PV arrays are comprised of 6400 high-efficiency Mitsubishi crystalline-silicon PV panels, which are positioned on ground-mounted, single-axis tracking systems.
The four 250kW AC solar systems replace fossil fueled-powered water pumps and are expected to produce 2.3 million kWh of electricity annually. The new 1MW system complements Limoneira’s existing 1MW “solar orchard” installed in its farm in Santa Paula, CA, in October 2008, bringing the company’s total installed PV capacity to 2MW (AC).
The solar system is owned by a third-party company, which permits Limoneira to buy 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. The solar arrays are expected to save the agricultural company $200,000 per year by lowering its overall electric rate and demand charges.
