Goldi Solar 525-550W HELOC Pro Series Bifacial Transparent Backsheet 144 Half-Cells Efficiency 21.30%

This series features advanced cell architecture and bifacial technology to maximize total energy harvesting. Cell Technology: Utilizes 144 bifacial monocrystalline Silicon (PERC) cells with Multi Busbar (MBB) technology for enhanced reliability and current collection. Bifacial Advantage: Equipped with a transparent backsheet (White/Black Mesh type) that captures light from the rear, achieving a bifaciality factor of $70\pm5\%$. Module Efficiency: Achieves a maximum conversion efficiency of up to 21.30% under standard testing conditions. Enhanced Power Output: Total power output can reach up to 605 Wp at 10% rear side power gain, depending on site albedo and mounting. PID Resistance: Guaranteed excellent Anti-PID performance to limit power degradation during mass production and long-term operation. Robust Build: Constructed with 3.2 mm high-transmission, AR-coated tempered glass and an anodized aluminium alloy frame (Silver/Black). Environmental Protection: Features an IP68 certified junction box with 3 bypass diodes for superior waterproof reliability. BenefitsHigh Commercial Savings: Delivers a lower Levelized Cost of Energy (LCOE) and reduced Balance of System (BOS) costs, resulting in a shorter payback time. Long-Term Performance: Backed by a 12-year warranty for materials and processing, along with a 25-year linear power output warranty. Low-Light Engineering: Optimized with advanced glass and a textured cell surface design to ensure excellent power generation in overcast or low-light conditions. Thermal Stability: Features a low temperature coefficient of Pmax ($-0.35\%/^{\circ}C$), ensuring consistent performance in hot environments. Mechanical Integrity: Certified to withstand heavy mechanical loads, including a 5400 Pa snow load and 2400 Pa wind load.
