Technical FAQs 4

Which battery should I use for a solar pump?

The Choice of Battery for a Solar Pump Depends on Factors Like Energy Needs, Solar Panel Capacity, and the Level of Solar Exposure. Commonly Used Batteries for Solar Pumps Include Lithium-Ion Batteries for Their Longevity and Efficiency.

How does a solar water pump work?

The system uses a solar panel to charge a 12v battery, which in turn can provide power to the water pump. A pushbutton is included in the circuit, likely to control the activation of the water pump. The solar panel and the battery are connected in parallel, providing a stable voltage source for the pump.

Can a solar cell power a pump?

The solar cell does not have enough power for the pump. Another way to power the motor inside the pump is to use a battery. So we tried connecting it to a 12V 5Ah battery, and now the pump functions properly. We also add in another of the same batteries in parallel to increase the current they can supply by two times.

How do I connect a solar panel to a water pump?

Negative Pin (-): Connected to the negative pin of the 12v Battery and the GND pin of the Water Pump. VCC (Power Supply): Connected to Pin 3 of the Pushbutton. GND (Ground): Connected to the negative pin of the Solar Panel and the 12v Battery. Pin 4: Connected to the positive pin of the Solar Panel.
