Tenka Solar TKA645M-132-BFD 640–650W TOPCon Bifacial Solar Panel
Model TKA645M-132-BFD | TOPCon | 132 Cells | Bifacial | 1500V System Voltage
Product Overview
The Tenka Solar TKA645M-132-BFD is a high-output bifacial solar panel designed for modern commercial and utility-scale projects. It uses TOPCon technology to support strong efficiency and dependable long-term performance. With a maximum output of 645 Wp, it is built for installations that demand more power from every square meter. The dual-glass construction and anti-reflection coating help improve durability and light capture. A 30-year product warranty and 30-year power warranty add confidence for long service life. The module is also engineered for stable operation in demanding climates and wide temperature conditions.
Key Benefits
High Power Output: Delivers up to 645 Wp for stronger energy production in larger solar installations.
Bifacial Design: Captures light from both sides to improve overall energy yield in suitable mounting environments.
TOPCon Technology: Supports efficient performance and helps the module maintain strong output over time.
Long Warranty Coverage: Includes 30 years of product coverage and 30 years of power warranty for added assurance.
Built for Harsh Conditions: Works across a wide operating range from -40°C to 85°C for reliable field performance.
Durable Construction: Features dual glass, anodized aluminium framing, and IP68 junction box protection.
How It Works
The Tenka Solar TKA645M-132-BFD converts sunlight into electricity through advanced monocrystalline cells and TOPCon engineering. Its bifacial structure allows the rear side to absorb reflected light from the installation surface. This can increase total energy generation when the panel is mounted in the right environment. The anti-reflection glass helps more sunlight reach the cells during daily operation. The module also supports stable performance across changing weather conditions. Its electrical design is optimized for high-voltage systems and strong current handling. Combined with durable materials, the panel is suitable for long-term solar generation in demanding applications.
Sunlight Conversion: The monocrystalline cells absorb solar energy and convert it into usable electrical power. This process is supported by a 20.76% module efficiency rating.
Bifacial Energy Capture: The rear side can collect reflected light from ground or roof surfaces. This helps improve yield when the installation allows rear-side exposure.
System Integration: The module is designed for 1500V systems and a 25A series fuse rating. This makes integration suitable for many commercial solar layouts.
