Technical FAQs 4

How much power does a water pump use?

However, the pump will typically draw 20-50% or more power than just that calculation based on real life usage, efficiency and power factor. For example, the RPS Pro Deep 1 HP uses 1,200 watts of solar panels. How high can a 12v water pump lift?

How much solar power does a water fountain need?

The higher the head, the more power you need. The Vecharged Rule of Thumb: For every 100 watts of solar panel, you can typically expect to pump around 1,000 gallons of water per day to a moderate height (e.g., 20-30 feet). Example for a Small 12V Fountain: A small 12V water fountain pump might only need a 20-watt solar panel.

How to choose a solar water pump?

After figuring out the solar array size, pick the right pump. Look at your water needs and the pressure. Choose a pump that can handle your daily water use and fits with the solar array. The number of solar panels needed to run a 1 hp water pump changes with the system’s details. A solar pump design calculation excel tool can give you a rough idea.

How many watts is a 1 hp water pump?

1 HP Submersible and surface water pumps used for livestock, off-grid living, irrigation or aeration all require a baseline amount of watts to effectively run the pump all day off of solar power. If you were to Google “HP to watts” a calculator would pop up and give you this answer. (insert photo) 1 HP equals 750 Watts.
