If the wires are too thin, they may overheat due to the resistance, jeopardizing both performance and safety. Overheating can lead to insulation failure or even electrical fires, which represents a significant hazard, not just to the solar system but also to the property. . The thickness of solar panel wires primarily hinges on two critical factors: 1. Thick wires are indispensable to effectively transmit the generated electricity from the solar panels to the inverter and ultimately to the electrical grid or battery storage. . Your solar panels could not operate as they should if your cables are either excessively long or too thin. You want least amount of Voltage drops so large gauge will have less Voltage drop. How much current are you talking about? How long are the cables? That will depend on what the temperature rating of insulation material is. . In general, cables can't be too thick. Worse still, improper sizing poses a serious fire hazard.
