Rosen Solar RSM550M-144BDG 550W Bifacial PERC Monocrystalline Solar Panel
Model RSM550M-144BDG | Bifacial PERC | 144 Cells | Bifacial | 1500V System Voltage
Product Overview
The Rosen Solar RSM550M-144BDG is a high-output bifacial monocrystalline solar panel built for demanding energy projects. It delivers 550 Wp of rated power with a strong 21.23% module efficiency. The panel uses PERC technology to support improved energy capture and stable performance. Its bifacial design helps generate additional power from reflected light. The module is designed for residential, commercial, and utility-scale solar installations. With a 144-cell layout, it offers a balanced combination of power density and reliability. The anodized aluminium frame supports long-term outdoor use. Anti-reflection coated glass helps improve light absorption. A 12-year product warranty and 30-year power warranty add extra confidence. This model is made in China by Rosen Solar Energy Co., Ltd.
Key Benefits
High Power Output: The module delivers 550 Wp for strong energy production in space-conscious installations.
Bifacial Design: Rear-side generation can improve overall yield when reflective surfaces are available.
Efficient PERC Cells: PERC technology supports better light utilization and dependable day-to-day performance.
Durable Construction: Anti-reflection glass, EVA encapsulant, and an anodized aluminium frame help protect the module outdoors.
Long Warranty Support: A 12-year product warranty and 30-year power warranty provide long-term buyer reassurance.
How It Works
This solar panel converts sunlight into electricity through monocrystalline cells arranged in a 144-cell configuration. The cells capture direct sunlight from the front surface and convert it into usable DC power. The bifacial structure can also absorb reflected light from the rear side, which may increase total energy output. PERC cell technology improves internal light reflection, helping the module maintain strong performance under varied conditions. The anti-reflection coated glass supports better light transmission, while the EVA encapsulant protects internal components from moisture and environmental stress. The anodized aluminium frame adds structural strength for reliable long-term operation. The junction box uses three diodes and IP68 protection to support safer electrical handling.
Sunlight Conversion: The monocrystalline cells absorb sunlight and convert it into electrical energy. The 550 Wp rating reflects strong output under standard test conditions.
Bifacial Gain: The rear side can capture reflected light from roofs or ground surfaces. This can improve overall generation in the right installation environment.
Protected Power Delivery: The junction box, MC4 connector, and IP68 protection help maintain stable power delivery. These features support safer integration into solar systems.
