Solar Pump Sizing: Check Pipe Losses Before Adding PV Panels
Before increasing the PV array, check whether the pipeline is making the pump work harder than necessary.

What the notes cover.
Selection: what decides the pump — the water source, the flow that is needed and when it is needed, the total head and the pipe run.
Sizing: how the array and the inverter are chosen for the duty point, and why the two are matched together rather than picked separately.
Installation: the run from the array to the inverter and from the inverter to the pump, the output filter and the parts around them.
After the order: what happens when a system is commissioned, and who to ask when something on site needs an answer.
Selection, sizing, installation, support.
