Solar pumping in Mae Sot

SolarWorld Singapore wanted to donate some old 50 Wp solar modules to an NGO in Thailand. We found BGET (Border Group Energy Team) interested in them to run a solar pump.
The water had to be pumped up some 40-50 meters from a shallow well to an area where they were planning to build a centre to educate Burmese refugee children in sustainable agricultural practices.
The site is at a small remote village near Mae Sot, on Thailand's western border with Myanmar.


The shallow well.
  

Work started first on the 1200 Wp array.
  


Then the HDPE pipe and array cable where laid into a trench, leading down to the shallow well.



The Grundfos SQFlex pump.


PVC cable conduit was used to protect the array cable.



The completed array. The pump started up immediately and supplied about 2000 liters of water per hour at 4 pm.
