Designed for utility-scale and commercial applications, the JA Solar 545W module operates at 39.52V maximum power voltage (Vmp) with a 13.85A current (Imp). Its open-circuit voltage reaches 48.25V (Voc), comparable to industry benchmarks for 210mm silicon wafer-based modules. The 545W rating represents peak output under Standard Test Conditions (STC): 1000W/m² irradiance at 25°C cell temperatur

Designed for utility-scale and commercial applications, the JA Solar 545W module operates at 39.52V maximum power voltage (Vmp) with a 13.85A current (Imp). Its open-circuit voltage reaches 48.25V (Voc), comparable to industry benchmarks for 210mm silicon wafer-based modules. The 545W rating represents peak output under Standard Test Conditions (STC): 1000W/m² irradiance at 25°C cell temperature.
Utilizing 150 monocrystalline PERC cells arranged in 10×15 matrix, the panel measures 1102mm × 2187mm × 35mm. The 3.2mm tempered glass front surface withstands 5400Pa snow loads and 2400Pa wind loads – crucial for installations in extreme climates. Anti-PID technology prevents potential-induced degradation in high-humidity environments.
Under NOCT (Nominal Operating Cell Temperature) conditions of 800W/m² irradiance, 20°C ambient, and 1m/s wind speed, the panel maintains operational stability between -40°C to +85°C. The bypass diodes (3 in total) activate at 0.6V forward voltage during partial shading events.
The module supports both portrait and landscape mounting orientations. When paired with microinverters like Enphase IQ8H, system-level CEC efficiency reaches 97.5%. Compatibility with trackers (single-axis or dual-axis) increases annual energy yield by 18-25% compared to fixed-tilt systems.
