15 Sep Seley Ranches
WorldWater & Solar Technologies completed the worlds largest solar-powered irrigation system at the time of installation.

Nestled between the Santa Rosa and Palomar Mountains in San Diego County lies Seley Ranch. The 267 kW system uses WorldWater’s patented technology, VariMax™ to drive the pumps and motors at 200 hp, irrigating 400 acres of citrus fruit. The large pump draws the water from a 1,000 foot well at a rate of 1,000 gallons per minute. Competitors can only drive a pump about 25 hp, WorldWater’s can manage adequately up to 600 hp.
When I realized that the grid had been cut off and a 200 hP pump, using only the energy from the sun above, was pumping 1,000 gallons of water a minute from a depth of 300 feet…well, that was a very powerful moment.
