What Determines the Output Current of a 325kW Solar Panel?

When evaluating a 325kW photovoltaic panel, the output current depends on three critical factors: system voltage, power factor, and environmental conditions. Using Ohm's Law (Current = Power / Voltage), a 325kW system operating at 480V AC would theoretically generate approximately 677 amps. However, real-world scenarios introduce variables like:

• Daily irradiance fluctuations (1,000-1,300 W/m²)
• Panel temperature coefficients (-0.3% to -0.5% per °C)
• Inverter efficiency rates (96-98%)
