A solar-powered pump is a pump running on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps. The operation of solar powered pumps is more economical mainly due to the lower operation and maintenance costs and has less environmental impact than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity is unavailable and alternative sources do not provide sufficient energy.
When the sun shines on the surface of your solar panels, the movement of electrons generates DC power which is transferred through attached wires to the pump controller.
The pump controller is the brains of the system and with sophisticated technology and sensor inputs, it turns the submersible motor and drives the pump to push water against gravity to the surface.
Solar pumps are sized by calculating the total vertical feet they’ll need to push water, the pressure they need to generate, and the total water required each day.
