Qiqiang Solar JKM625N-78HL4-BDV 625W N-Type TOPCon Bifacial Solar Panel
JKM625N-78HL4-BDV | N-Type TOPCon | 156 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Qiqiang Solar JKM625N-78HL4-BDV is a premium 625W solar panel designed for high-performance energy generation. This advanced module utilizes N-type TOPCon technology to maximize efficiency and reduce power loss over time. Its bifacial dual-glass design captures sunlight from both sides, significantly boosting overall power output. The panel features Hot 2.0 technology for enhanced reliability and lower LID/LETID degradation rates. Built with robust anodized aluminum framing and anti-reflective glass, it withstands harsh weather conditions including heavy snow and wind loads. This 625W panel is ideal for large-scale commercial installations and residential projects seeking maximum energy yield.
Key Benefits
Ultra-High Efficiency: Achieves up to 22.36% module efficiency for superior energy conversion per square meter.
Bifacial Power Gain: Captures reflected light on the rear side, increasing total power output by 5% to 25%.
N-Type Durability: N-type cells offer lower degradation rates and better performance in low-light conditions.
Enhanced Reliability: Hot 2.0 technology ensures lower LID/LETID and improved long-term module stability.
Extreme Weather Resistance: Certified to withstand 2400 Pa wind load and 5400 Pa snow load for safe operation.
How It Works
This solar panel converts sunlight into electricity using advanced photovoltaic cells. The N-type TOPCon structure minimizes electron recombination, allowing more current to flow efficiently. Its bifacial design captures direct sunlight on the front and reflected light on the rear glass. This dual-sided absorption significantly increases total energy generation compared to traditional monofacial panels. The Hot 2.0 technology further optimizes current collection and reduces thermal losses during operation.
Photovoltaic Conversion: Sunlight strikes N-type monocrystalline cells, exciting electrons to generate direct current electricity. The TOPCon layer reduces resistance and improves electron flow efficiency.
Bifacial Energy Capture: The dual-glass design allows rear-side photons from ground reflection to generate additional power. This feature boosts total output by up to 25% in optimal conditions.
Thermal Management: The module operates efficiently within a wide temperature range of -40°C to +85°C. Low temperature coefficients ensure stable performance even under extreme heat.
