How big a solar panel does a 300w 12v water pump need

In this scenario, you sacrifice the economies of design of an AC motor, and go with an old-school series-wound DC motor. This will have a commutator and brushes, which means a high wear point. This motor will also have a "near short" condition demanding limitless current from the. . This uses a new style of DC motor that must be driven like a stepper motor, with several field windings under the control of silicon power. . In this case, we bite the bullet and add a battery so that the solar system can borrow from the battery to provide the "bottomless" energy. . This works the same as a brushless DC motor, except it's using a bog-standard off-the-shelf AC 3-phase motor as as replacement for the brushless DC motor. Instead of a magnet. I would budget 450W of panels (50% overhead). you will also want a small battery to prevent short-cycling the pump on an off during borderline conditions. you will also need a modest inverter to turn the solar/battery DC into AC for the pump. Based on our calculations and real-world conditions, you would need approximately 18 solar panels, each rated at 300 watts, to sufficiently power your well pump while accounting for various efficiency losses.
