Good solar water pumping companies in Mali?

This is an update on "Cost and reliability of solar pumps in Mali?"

I am drilling some new wells and rehabilitating / replacing a number of PV powered water pumps in northern Mali (both drinking water and irrigation, but all are submersible pumps in boreholes). Many systems in the area are no longer working, and I even see relatively new (<1 year) systems both Grundfos and Lorentz that have failed. Unfortunately, I do not yet know the reasons for this failure trend, as the reports I receive from local consultants do not contain any diagnostics on the systems or even photos of failed parts.

Going forward, what are recommended installation companies for 5-15m3/hr solar powered pumps? And which companies do the best inspection and appraisal, both for new wells and for existing?
