Corab EC505N-10R-120B 505W N-Type Monocrystalline Solar Panel
Model EC505N-10R-120B | N-Type Monocrystalline | 120 Half-Cell | Mono | 1500V System Voltage
Product Overview
The Corab EC505N-10R-120B is a high-efficiency monocrystalline solar panel built with advanced N-type half-cut cells. It is designed for reliable performance, strong energy yield, and long-term durability in demanding rooftop and commercial installations. With a rated output of 505 Wp, this module delivers excellent power generation in a compact format. The black anodized frame and tempered glass construction support a clean appearance and dependable outdoor use. Its low temperature coefficient helps maintain stronger output under heat, while the 30-year performance warranty provides added confidence for long-term projects.
Key Benefits
High Power Output: Delivers up to 505 Wp for strong system performance and efficient energy production.
Excellent Efficiency: Reaches 22.31% module efficiency for better energy harvest from limited roof space.
N-Type Half-Cell Design: Supports lower degradation and improved output stability across the module lifespan.
Heat-Resistant Performance: The low temperature coefficient helps preserve output in warmer operating conditions.
Durable Construction: Tempered glass, IP68 junction box protection, and an anodized aluminium frame improve reliability.
Long Warranty Coverage: Includes 15 years product warranty and 30 years power warranty for added assurance.
How It Works
This solar panel converts sunlight into usable electrical energy through N-type monocrystalline half-cut cells. The half-cell layout reduces resistive losses and helps improve performance under partial shading. When sunlight reaches the panel surface, the tempered glass protects the cells while allowing efficient light transmission. The generated DC electricity is then carried through MC4 connectors to the inverter and balance-of-system components. The module is engineered to maintain stable performance across a wide range of temperatures. Its low degradation rate supports dependable long-term output for residential and commercial solar systems.
N-Type Cell Conversion: Sunlight is absorbed by the N-type monocrystalline cells. Electrical current is produced efficiently, even in challenging light conditions.
Half-Cell Architecture: The 120 half-cell design lowers internal resistance. This supports improved output and better shading tolerance.
System Integration: Power is delivered through MC4 connectors and a 1500V compatible design. This makes installation straightforward in modern PV systems.
