Can I Run A Water Pump Straight From A Solar Panel?
With our DC Direct Solar Pumps, there''s no need for a big inverter to power the pump. In fact, we see that most water pumping applications are well suited for solar systems that are directly
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.
Most common DC water pumps can work directly connected to the solar panel without a battery, but their biggest problem is that they can get stuck.
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.
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.
