4 FAQs about How big a water pump can a 200w solar panel support

How much wattage does a solar water pump need?

Let's say you want to pump water from a depth of 50 feet at a rate of 5 GPM using a 12V pump that is 70% efficient. The region receives an average of 6 hours of sunlight per day, and you want to use a 12V solar panel and battery. Using the Solar Water Pump Sizing Calculator, the minimum solar panel wattage required is calculated as follows:

What is a solar water pump sizing calculator?

The Solar Water Pump Sizing Calculator is an essential tool for individuals who rely on solar power to pump water. By providing the required input data, users can accurately calculate the minimum solar panel wattage and battery capacity required to meet their water pumping needs.

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 efficient is a solar pump?

DC pumps are ultra efficient because they take the DC power directy from the solar panels and send the power down through the controller to the pump. Two panel solar pumps will run the entire day, just like a twenty panel 5 HP pump, as long as the sun is shining. Smaller systems like the RPS 200 will only pump around 3 -5 GPM.
