  1. Do you have information on solar power panel and pump requirement for crop watering ie not in wattage terms but in volume of water needed to pump and number of outlets

    • Hi Chugge, regarding the volume of water. That is more about the horsepower of a water pump.

      Then the job now easier, you need to know how many horsepowers you need for the total water volume and total outlets. Then you can shop based on that requirements.

      Finally, you can look at the wattage of the pump you are going to buy, using the table above to calculate the number of solar panels needed.

      For better usage, you should have a battery if you want to run your pump during the night time.
      Can I know how many outlets you have and how much water you need for a day? I do have a small watering system and it only requires a single 200 watt solar panel.

  2. I have a farm that requires flood irrigation through 3 inch water pipes. I currently have a diesel operated motor that runs 8 hours a day. Everyday !
    What horsepower pump and wattage pump would I need run the same amount of water as my desiel motor through 3 inch pipes.

  3. Good day!
    We have a 15m deep water well with 2mx2m hole and just beside a creek. The wall of the well is a hard rock and is full with water.
    What will be the right specs of the submersible pump, inverter and solar power for this? Water will be used for wateing vegetable garden of 1000 sqm. area

    • Good day Ed,
      Can I know where do you stay? It will affect how much water you should have.

      But in general, you might need a 500W-1000W water pump system. Among with solar panels for about 2 times pumping a day.

      Regarding the inverter, you can use POTEK 500W. It would be enough for you, but I would suggest you go with a Fronius 1500W. It would benefit you in the future if you need to run more appliances.

  4. I need a sollar water pump to be connected with solar panesl to produce 3 inches diameter of water flow, the water will collected in a reservoir and then can be used for irrigation

  5. Some of the information on this site is false. Solar panels are not entirely eco friendly. The waste products from solar panels and the batteries necessary to store the energy they produce are just a different type waste than fossil fuels. The heavy metals like cadmium and lead that are found in solar cells, can harm the natural environment if they are not recycled or disposed of properly. They are not currently recyclable and must be considered hazardous. The batteries are recyclable but they contain highly toxic materials and are also considered hazardous. You should try some honesty instead of just bad mouthing other energy resources.

    • I agree that there are some waste products from solar panels that are not eco friendly. But if you compare it with other energy sources and their waste products, I think you know what to go.
