How Many Solar Panels are Required to Run 1 HP Motor?

How many solar panels are required to run 1 HP motor? Using solar power is a really good option to reduce energy consumption from the grid.

Based on the capacity of solar panels we can run almost everything which we use to on mains supply. So let’s come to the main topic, how many solar panels would be required to run 1 HP (0.75 KW) submersible water pump?

First, learn what is the total power consumption of 1 HP submersible water pump’s motor.

1 HP (HorsePower) = 746 Watts

But, it is not enough!

Because any electric motor draws considerably more about 2-3 times electric power to just start the motor, later on, it shifts to its normal energy consumption. Such initial load is known as torque, moment, a moment of force, or turning effect.

So, clearly, 1 KiloWatt Solar Panels wouldn’t be enough to run the 1 HP motor even under full sunshine even when no other load is given to the solar system. You will need around 1875 Watts or more just to start the 1 HP water motor and run it smoothly on solar power.

We recommend up to twice-or-trice capacity like 2-3 Kilowatt Solar system to run a few other loads while running the 1 HP water motor. If you can, buy the MPPT solar charge controller over PWM, so you get the most from solar energy.

Some modern hybrid inverter has an inbuilt solar charge controller. Do your own research. For further installation and full solar system set up get in touch with your nearest solar supplier or engineer. In India, Loom Solar, Luminous, Microtek are known vendors.
