Low Cost Solar Irrigation — 4 Comments

  1. I have two 12 volt pumps. One submersible and the other inline. The inline one puts out about 49 PSI so that’s good enough for the house. My submersible pumps 2 gallons a minute at 200 feet below surface no problems.

    I think I spent 300 for both of them.

  2. A one HP pump? Seems a bit much to me.I see, im into small aquaponics systems. I don’t think large fields needing large amounts of water is a very good idea.A lot of waste.
    A small greenhouse with Aquaponics can feed a family and you get fish out of this method.

    • Many people who would benefit from solar pumping don’t have greenhouses. They live in hot climates such as India and Africa where greenhouses aren’t needed. Fields allow them to grow large quantities of food for market. They’re farmers. Combine solar pumping with drip irrigation and this concept can greatly improve the lives of around 1 billion people. Affordable irrigation is one of the greatest needs in the world. Watch that last video and you’ll see how the government is gearing up to finance tens of thousands of these solar pumps. There are around 2-3 million diesel irrigation pumps just in India. They use expensive fuel and frequently require maintenance. If the price of solar continues to drop, solar irrigation systems will soon be used by millions.

      Interesting option to consider: The last video shows a solar water pump being used in combination with a shade cloth structure. This is another idea that can help millions of farmers and homesteaders. The shade cloth enables you to grow a wider range of crops at higher yield using less water. Some are open air. Some are enclosed to keep insects out.
