How big a water pump can a 200w solar panel support

How much solar power does a water pump need?

First, you need to know the pump’s power requirement, which is typically measured in watts (W). Divide the pump’s wattage by the average peak sunlight hours your location receives daily. For example, if your pump requires 1500W and you get 5 sunlight hours per day, you would need at least a 300W solar panel.

What is a solar water pump system?

A solar water pump system typically consists of the following components: Solar Panels: These convert sunlight into electricity. Controller: It regulates the power from the solar panels to the pump. Pump: This is the device that moves water from the source (well, river, or reservoir) to the desired location.

How many solar panels do I need to run a submersible pump?

The number of solar panels needed to run a well pump depends on the HP of that well pump. RPS systems range from only needing 2 solar panels (100W each) for a 1/2 HP pump to around 20 solar panels for a 5 HP.

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.
