​How To Choose Solar Panels for Your Pump（Example：550W 36V ）

Step of choosing panels:

1. 1.Voltage Calculation: Divide your pump’s voltage by 36V (solar panel voltage) to get voltage-based panel count.

2. 2.Power Calculation: Multiply your pump’s power by 1.3~1.5, then divide by 550W to get power-based panel count.

3. 3.Compare & Choose: Pick the larger number from the two calculations.
