WINAICO WST-625NHX66-A4 625W N-Type HJT Bifacial Solar Panel
Model WST-625NHX66-A4 | N-Type HJT | 132 Cells | Bifacial | 1500V System Voltage
Product Overview
The WINAICO WST-625NHX66-A4 is a high-output solar panel built for utility and large-scale projects. It combines monocrystalline N-type HJT cell technology with a bifacial glass-glass design for strong energy production and long-term reliability. With a rated power of 625 Wp and module efficiency of 23.1%, it is designed to capture more usable energy from limited roof or ground space. The panel also offers a 15-year product warranty and a 25-year power warranty with 91.8% output at year 25 and 90.3% at year 30. Its robust construction, 1500V system rating, and wide operating range make it suitable for demanding installation environments.
Key Benefits
High power output: Delivers 625 Wp, helping systems generate strong energy yield from each module.
Excellent efficiency: Reaches 23.1% efficiency, which supports better performance in space-conscious installations.
Bifacial energy capture: The bifacial HJT design can capture light from both sides for improved total generation potential.
Long-lasting warranty support: Includes 15 years product coverage and 25 years of linear power assurance.
Strong environmental durability: Operates from -40°C to 85°C and is engineered for stable performance in harsh climates.
How It Works
This module converts sunlight into electricity through advanced N-type HJT cell architecture. The cell structure is built to reduce energy losses and improve conversion efficiency. Its bifacial design allows the rear side to absorb reflected light, which can increase output in suitable installations. The glass-glass construction adds durability and supports long service life. Because the module is designed for utility-scale use, it performs best where spacing, mounting height, and ground reflectance can be optimized.
N-type HJT cells: These cells help improve efficiency and support better performance under real-world operating conditions. They are also well suited to long-term generation needs.
Bifacial glass-glass construction: The rear side can capture additional reflected light. This can increase total system yield when the mounting surface supports bifacial gain.
Temperature-resistant design: The module is built to maintain dependable output across wide temperature swings. Its temperature coefficients help limit performance loss in hot conditions.
