Technology
Bifacial Technology: This is a core element. Unlike traditional solar panels that only capture sunlight from the front, bifacial panels absorb sunlight from both the front and rear surfaces. This significantly increases energy yield, especially when the panels are installed over reflective surfaces.<!–>–>
PERC Technology: The panel utilizes Passivated Emitter Rear Contact (PERC) technology. This technology adds a reflective layer to the back of the solar cells, enhancing light capture and improving overall efficiency.<!–> –>
Half-Cut Cell Technology: The panel incorporates half-cut cell technology, where each solar cell is cut in half. This reduces resistive losses within the panel, leading to improved performance and increased power output. It also improves the panel’s performance in shaded conditions.
Durability and Reliability: Robust frame design to withstand harsh weather conditions. Resistance to PID (Potential Induced Degradation), salt mist, and ammonia. Tempered glass for added strength.
Applications
High-performance residential solar installations.
Installation
The Hyundai HiS-S390PI features a robust yet lightweight aluminum alloy frame, ensuring durability and easy installation. The IP68-rated junction box offers maximum protection against dust and water ingress. This module is compatible with standard racking systems, allowing seamless integration into various solar setups.
Advanced Technology
Equipped with PERL (Passivated Emitter Rear Locally-Diffused) Technology, the HiS-S390PI significantly improves light absorption and electron efficiency. This technology optimizes the panel’s performance under low-irradiance conditions, making it ideal for areas with variable sunlight exposure.
