In general, you'll need around 80 watts of solar power for every 1 horsepower (hp) rating on your motor. . However, the precise number of solar panels necessary to run a 2 HP motor depends on various factors such as the motor's energy consumption, average sunlight exposure in your area, panel efficiency, and other considerations. A new RPS 1 HP, three-phase pump uses twelve 100W panels, totaling 1200W. Larger panels like 300W could be used, reducing overall panels but maintaining the same square footage. However, this is just a rough estimate, actual panel requirements will vary based on all of the aforementioned factors. 5 kW to 5 kW or more, dictating the amount of solar energy. . The horse walker has a 2KW motor which will be running for about an hour or so every day (1-2hrs).
