Renewable Energy#6: Solar deep-well pump
Posted: Wed Apr 05, 2017 10:23 am
To have enough water in Summer to top up the pool or watering your orchard is in some areas problematic. It is not only the high water bills that concern. If you had plenty of own water from a well in the garden you could decide to grow fruits and vegis, herbs, or have a little meadow with African grass (resists the heat), not only stones and barren land in the hot Summer. You could then perhaps do organic farming and you would have products where you know they are pesticide-free and grown with less fertilizer. If there is no well yet you could drill one. Bore holes max. 30 feet need no permit to drill. They are the so called "Lakkous" and are done with concrete rings 1 m diameter. If there is no water at 30 feet you have to apply for permit to the Authorities (supplier will do it) to drill for a proper bore hole with 8 inch. In order to find water you need somebody who can tell you where exactly is the position to drill successfully. (Diviner, ask me) If they found only very little water <2 tons/h) THEN a solar driven bore hole DC pump comes in. 2-3 photovoltaic modules are only necessary. Unlike conventional AC pumps a solar pump lifts only a small amount of water at a time with the power of the Sun. This avoids that mug and sand is sucked into the pump as it would be with a normal AC pump which works only full speed or not at all. 90% of drilled bore holes in CY contain enough water to be lifted up with a solar pump. If there is plenty of water of course a normal AC pump can do the job. Water pumped from a solar system goes normally without pressure into a deposit tank of 2-8 tons to use it from there.
Conclusion: Only Solar pumping works when there is not much water in a well.
