LONGi Hi-MO 7 620W Monocrystalline Solar Panel

Description

​Overview
The LONGi Hi-MO 7 620W Monocrystalline Solar Panel is a state-of-the-art power solution engineered for high-demand solar installations. By utilizing n-type TaiRay silicon wafers and HPDC (Hybrid Passivated Dual-Junction Cell) technology, this panel achieves exceptional energy conversion rates. Its bifacial design allows for significant energy gains from the rear side, making it an ideal choice for large-scale utility and commercial applications where maximizing energy harvest per square meter is essential.
​Key Features
​High Efficiency: Achieves module efficiency of approximately 23.0%–23.1% through advanced cell processing.
​Superior Temperature Coefficient: Features an optimized temperature coefficient of -0.28%/°C, ensuring stable and reliable performance even in high-temperature environments.
​Bifacial Technology: Offers high bifaciality (approx. 80%), allowing the panel to capture light from both sides to increase overall energy yield.
​Robust Durability: Constructed with dual-glass and an anodized aluminum frame to withstand significant mechanical loads, including 5400 Pa front and 2400 Pa rear static loading.
​Low-Light Performance: Engineered to maintain efficient energy generation during low-light conditions, such as overcast days or during early morning and late evening hours.
​Long-Term Reliability: Backed by a 12-year material and processing warranty and a 30-year linear power output warranty with minimal annual degradation (0.4%).
