What good guidance documents can you recommend for designing and installing a solar pump for tube-wells in a developing country setting?

Any experience with upgrading existing hand-pumps to a low-maintenance solar pumping system?

Any recommendations for suppliers & country specific lessons learned?

There are two pieces of information we need to select a solar water submersible pump to meet their needs – they are:

  1. Pumping Rate: How many gallons per minute will the pump need to move water when it’s powered by the sun( source)?
  2. Effective Dynamic Head: How high, vertically, will the pump have to move the water up? Plus, how much effective head is added due to friction loss in the pipe?
