Solar Panel Output Imbalance Between Strings: Diagnose and Fix It
Solar panel output imbalance between strings occurs when parallel photovoltaic strings produce materially different voltage, current, or power under comparable sunlight and temperature. The difference can result from shading, soiling, unequal design, failed modules, wiring resistance, or MPPT assignment, but unequal readings do not automatically prove a hardware fault.
