4 FAQs about How big a solar cell should I use with a 12V water pump

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:

Can a solar panel power a water pump?

Also, there is chance your solar panel might create more than 12v power, in which your water pump will get damage in long run. To avoid this situation, you can simply connect DC buck converter between your solar panel and water pump which will help to supply only upto 12v power to your water pump.

Do I need a DC water pump if I have a solar panel?

A 12v 10w solar panel will create DC power. You need a DC water pump if you want to run it directly from your solar panel. Also, there is chance your solar panel might create more than 12v power, in which your water pump will get damage in long run.

Do I need a 12V DC pump for a solar panel?

You'll need a 12V DC pump. Solar panels have a non-linear voltage/current curve. The actual voltage and current depends on the load. This graph is from a different solar panel (from this answer) with more current - same voltage though: The specifications for your solar panel: You show two motors.
