GCLSI 660 660W Bifacial Monocrystalline Solar Panel
Model No. 660 | Monocrystalline | 132 Cells | Bifacial | 1500V System Voltage
Product Overview
The GCLSI 660 is a high-output solar panel designed for strong energy production and reliable long-term performance. This bifacial monocrystalline module combines a 660 Wp maximum power rating with 21.2% panel efficiency, making it suitable for demanding commercial and utility-scale projects. Its 132-cell format supports efficient power generation in a compact, durable structure. The panel also includes a 12-year product warranty and a 30-year power warranty, which adds confidence for project planning and lifecycle value. With a 1500V maximum system voltage, it is built for modern solar installations that require efficient string design and dependable operation.
Key Benefits
High Power Output: The module delivers 660 Wp for strong energy generation in large-scale systems.
Bifacial Design: Rear-side light capture can improve total system yield in suitable installations.
Efficient Conversion: A 21.2% efficiency rating supports excellent performance from available roof or ground space.
Long Warranty Support: A 12-year product warranty and 30-year power warranty provide added ownership assurance.
Robust Build: The anodized aluminium frame and anti-reflection coated glass help support durability and performance.
How It Works
This solar panel converts sunlight into usable electricity through monocrystalline cells arranged in a 132-cell bifacial format. The front surface captures direct sunlight, while the bifacial structure can also use reflected light from the installation surface. That extra capture potential can improve total energy yield in the right environment. The anti-reflection coated glass helps light enter the module more effectively. The low temperature coefficients support stable operation as conditions change throughout the day. The panel is engineered for modern PV systems that require high voltage capability and dependable electrical performance.
Sunlight Conversion: The monocrystalline cells convert incoming solar radiation into direct current electricity. The 660 Wp rating reflects strong output potential under standard test conditions.
Bifacial Energy Gain: The bifacial structure allows light from the rear side to contribute to generation. This feature is especially useful on reflective ground surfaces and optimized mounting systems.
System Integration: The 1500V system voltage and 35A fuse rating support efficient string design. These values help the module fit into larger commercial solar architectures.
