reetings from sunny Southern California. But many of us in San Diego County say we actually live
south of Southern California. Not When the Surf’s Up Renewable Farm-School (NOWSURFS) is located at the southern foot of Mt. Palomar, home of the famous astronomical observatory and about an hour from the beach.
“Not When...” is a market garden, selling at five farmer’s markets a week which we service via a propane powered ‘66 Ford pick-up. Almost all our seed, that we don’t save ourselves, comes from non-profit Native Seeds SEARCH in Tucson, Arizona. Our energy for irrigation (from 1 to 3 acres depending on the season) and household/office needs comes from five Arco quad- lams feeding eight Trojan 105s and a Trace 612 inverter, and an AIR 303 wind machine. We have a Honda 6500 back-up generator, a Todd 75a charger and a Lincoln welder back-up generator. Our main
loads are an Amiga A2000, 060/50 with a 1 gig hard disk computer which we are converting to DC power and a Maytag ringer washer using a Bosch 12 Volt Volkswagen generator as a motor (see HP #40 pg 40).
As part of the National Tour of Solar Homes this year, we have attracted interest in Latin America among farmers who would like us to help them with closed loop energy/agriculture. If you are inputting exotic energy, then your “organic” farm is not sustainable.
We have accumulated a lot of experience in solar water pumping for a small agriculture, very dry environment (14 inches yearly average rainfall). We use two “slow” type pumps, one 24 V and the other a 120 VDC pump (using 12 Volts converted to 95 Volts via a Vicor custom DC/DC converter, see HP #40 pg 70) and a PV powered (24 Volt) “stock” Jensen Jack pump. We pump all our irrigation water direct to field (the most efficient way) with a Doughboy 7500 gal. pool as a back-up, gravity-feed tank for emergency watering, household use, and fire safety. The tank is filled periodically by our generator-driven back-up pump, a Grundflos 12 GPM ac centrifugal.
