Goldi Solar 500-550W HELOC Pro Series Monofacial 144 Half-Cells Efficiency 21.30%

This series is engineered to deliver reliable power output through advanced cell and module architecture. Cell Technology: Powered by 144 half-cut monocrystalline Silicon (PERC) cells with Multi Busbar (MBB) technology for optimized current collection. Module Efficiency: Achieves a maximum conversion efficiency of up to 21.30% under standard testing conditions. Low-Light Engineering: Features advanced glass and cell surface texturing designed to ensure excellent performance in low-light environments. PID Resistance: Guaranteed excellent Anti-PID performance to limit power degradation in mass production and long-term field use. Robust Construction: Built with a 3.2 mm high-transmission AR-coated tempered glass and a silver anodized aluminium alloy frame. Advanced Protection: Includes an IP68 certified junction box with 3 bypass diodes for high waterproof reliability. BenefitsCost Efficiency: Lowers LCOE and reduces Balance of System (BOS) costs, resulting in a shorter payback time for investors. Weather Resilience: Certified to withstand heavy mechanical loads, including a 5400 Pa snow load and 2400 Pa wind load. Long-Term Security: Backed by a 12-year warranty for materials/processing and a 25-year linear power output warranty. High Temperature Performance: Optimized with a low temperature coefficient of Pmax ($-0.34\%/^{\circ}C$) to maintain stability in hot climates. Hassle-Free Installation: Designed with MC4 compatible connectors and high-quality 4 mm² solar cables for easy system integration
