6 FAQs about [How big a solar cell should I use with a 12V water pump]

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.

How many solar panels do you need for a water pump?

For a 1 HP Water Pump: Typically, you need around twelve 100-watt solar panels, totaling 1200 watts. For a 2 HP Water Pump: You might need about 24 panels, depending on the wattage of each panel and the efficiency of the pump. For a 3 HP Water Pump: Around 36 panels may be required, again depending on the specific setup.

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.

How many solar panels does a well pump need?

3.81 kW 250 watts = 18 panels Based on our calculations and real-world conditions, you would need approximately 18 solar panels, each rated at 300 watts, to sufficiently power your well pump while accounting for various efficiency losses. Understanding the energy needs of your water pump is critical.

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.

What varies in both water pumps and solar panels?

The wattage produced by different sizes of solar panels varies too, just like the power needs of water pumps vary by the size of the pump. There are tiny pumps and mega pumps, and tiny solar panels for tiny gadgets and large solar panels that form arrays.
