A tool that determines the appropriate gauge and type of conductors for photovoltaic systems. It factors in voltage, current, distance, and allowable voltage drop to ensure safe and efficient electricity transmission from solar panels to the load or battery bank. For example, inputting the total panel current, the length of the wire run, and the desired voltage drop yields a recommended wire size.
Proper conductor sizing is crucial for system performance, safety, and longevity. Undersized wiring leads to excessive voltage drop, reducing power output and potentially damaging equipment. Overcurrent situations can cause overheating, creating a fire hazard. Utilizing this type of calculation is rooted in electrical engineering principles developed over decades to address the complexities of power transmission and distribution, adapted for the specific characteristics of solar energy systems.
