Solar Water Pumps: The Ultimate Guide (Sizing, Cost & Installation)
This is our definitive guide to the world of solar water pumps. We will walk you through how they work, how to size a system, how to connect the components, and what to
When wiring your solar water pump, the first thing you must do is connect the solar panels to each other. You may connect all the panels in series or parallel. But since the solar power system of solar water pumps is typically large, series connection might be the better option.
Place the solar panel in a sunny spot. Connect the positive and negative terminals to a charge controller. Attach the pump's power wires to the solar panel or battery. Secure the inlet pipe in a water source (e.g., tank or well). Position the outlet pipe to direct water where needed. Ensure the pump starts when the sunlight hits the panel.
You could connect a solar panel directly to a water pump. It is not a good idea, though. The erratic pulse of electricity produced by the solar panel will burn out the pump at some point. That process can take a few seconds to a few years. The point is that connecting solar energy directly to a water pump shortens the life of the pump.
Solar-powered water pumps and solar water pump controllers have terminals labelled L1, L2, L3, and Ground. Connect the L1 terminal of the solar water pump to the L1 terminal of the controller. Then connect L2 to L2, L3 to L3, and ground to ground, and everything should work fine.
