I installed the pump directly on the solar panel 280w 24v 100ft head. The productivity is 16 l/min. Due to the gauge of the wire and the voltage drop, the pump works reliably at 31V, even though the open circuit voltage of the panel is 36V. When the sun is shining brightly, the pump starts automatically and stops when a cloud passes. The only question that remains is how long the pump will run. So far this is working very well.
