Start by checking your pump's voltage (typically 12V, 24V, or 48V DC) and wattage rating. Then, match the panel output to the pump's input requirements. It's best to choose slightly larger solar panels than calculated to offset energy loss during conversion. . Solar panel efficiency – Usually between 15–22%. Days of autonomy – How many days your system should run without sunlight. For example, a 1000W pump requires at least 1500W of solar panels. Use solar panel specs (VOC, VMP, power) to configure series and parallel connections, based on whether your pump is. . Typically, 100 to 375-watt panels are used, depending on the pump's specifications and whether it's single-phase or three-phase. Proper sizing ensures efficient operation and longevity of the pump. Battery Voltage: The voltage rating of the battery, which can be 12V, 24V, or 48V. This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires).
