150 kW (kilowatt).
Power factors of air power and solar power. The power factor of solar power is lower, around 10-20%, while the power factor of overhead power is higher, up to 30-40%. This means that with the same energy input, the production power of solar energy is only half that of aerial energy. When selecting a circulation pump, priority should be given to air energy and total system power. The total power factor of 5 horsepower of air energy plus solar energy is (1+0.5) = 1.5 times. The required power of the circulation pump should be 1.5 times higher than the required power.
