Model SF590M10 | PERC Monocrystalline | 156 Full-Cell | Monofacial | 1500V System Voltage
The Qinhuangdao Saikang SC SF590M10 590W PERC monocrystalline solar panel is engineered for projects that demand high output and reliable efficiency. This powerful module delivers up to 590 watts of maximum power while maintaining panel efficiency up to 21.12 percent across the range. Designed with advanced PERC cell technology and a robust monocrystalline cell layout, it supports modern high-voltage arrays with a maximum system voltage of 1500 volts. Installers can use this solar panel confidently for commercial rooftops, utility scale systems, and large ground mount projects where every square meter must perform efficiently. A durable tempered glass front and anodized aluminium frame provide strength in challenging conditions, while the IP68 junction box helps ensure long term electrical safety and reliability in outdoor environments. With strong warranties and controlled degradation, the module offers dependable energy production for many years.
High power density for large arrays: Up to 590 W of rated output allows more system capacity from fewer modules. Project designers can reduce racking, wiring, and labor per installed kilowatt while still reaching ambitious production targets.
Efficient use of roof and ground space: Module efficiency up to 21.12 percent helps capture more energy from limited surface area. This benefit is valuable on constrained rooftops and high value land where every panel footprint matters.
Reliable long term performance: A 12 year product warranty is paired with a long power warranty that maintains 90.88 percent output at 12 years and 80.68 percent at 25 years. The low annual degradation rate of around 0.77 percent supports predictable yield forecasts.
Stable output across temperatures: Optimized temperature coefficients for power, voltage, and current help maintain strong performance in hot climates. The module operates reliably from minus 40 to 85 degrees Celsius, supporting diverse site conditions.
Robust build for demanding sites: Tempered glass with 3.2 millimeter thickness and an anodized aluminium frame offer mechanical strength and weather resistance. An IP68 rated junction box increases protection against dust and moisture in the field.
This high efficiency PERC monocrystalline solar panel converts sunlight into electricity through an array of 156 precision manufactured cells. When sunlight hits the PERC cells, photons are absorbed and free electrons are generated inside the semiconductor material. These electrons move through the cell structure and create direct current that flows through the laminated circuits and the junction box. The module is then connected in series and parallel with other panels to build strings that match the voltage and current requirements of the inverter. Under standard test conditions, the main configuration delivers 590 watts of power at a voltage of 44.49 volts and current of 13.27 amperes. The design also supports a slightly lower power variant around 439 watts, which runs at 41.46 volts and 10.59 amperes, allowing flexible system engineering when both versions are specified together.
PERC monocrystalline energy conversion: Passivated emitter and rear cell technology is used to increase light capture and internal reflection. More of the incoming sunlight remains inside each cell, which improves electron generation and boosts overall module efficiency.
Current and voltage management: At maximum power, the module runs close to 44.49 volts with a current of 13.27 amperes in the 590 watt configuration. Open circuit voltage reaches about 53.76 volts, while short circuit current rises to around 13.97 amperes, giving designers clear parameters for safe string sizing.
Thermal and environmental operation: The panel operates within a wide temperature range from minus 40 to 85 degrees Celsius. Temperature coefficients of minus 0.35 percent per degree Celsius for power and minus 0.275 percent for open circuit voltage help predict performance on hot days. A positive temperature coefficient of 0.048 percent for short circuit current reflects the small current rise as cells warm.
