Uniteck UNISUN 120.12 BC 120W Monocrystalline Back Contact Solar Panel
Model UNISUN 120.12 BC | Monocrystalline Back Contact | 32 Cells | Back Contact | 12V System Voltage
Product Overview
The Uniteck UNISUN 120.12 BC is a compact monocrystalline solar panel designed for efficient off-grid power production. Its back-contact cell design helps maximize the active surface area, supporting strong performance in a small footprint. With 120 Wp output, 20.78% efficiency, and a rugged build, it suits marine use, campervans, isolated sites, and signaling systems. The panel combines tempered glass, an anodized aluminium frame, and a sealed junction box for dependable outdoor operation. Its lightweight 7 kg construction also makes installation easier where space and weight matter most.
Key Benefits
High-efficiency output: The 20.78% module efficiency supports better energy harvest from limited roof space.
Back-contact design: Electrical contacts are placed behind the cells for a cleaner active surface and improved light capture.
Compact and lightweight: At 1050 x 550 x 35 mm and 7 kg, the panel is easier to position and handle.
Built for harsh conditions: Tempered glass and an anodized aluminium frame improve resistance to impact, corrosion, and outdoor wear.
Reliable low-light performance: The multicouche structure is intended to deliver strong results when sunlight is limited.
Easy system integration: The 900 mm cable length and fast connectors simplify wiring in small solar systems.
How It Works
This panel converts sunlight into usable direct current through 32 monocrystalline cells. The back-contact layout moves the electrical connections to the rear of the cells, which helps leave more exposed surface for light absorption. That design is especially useful when maximizing power from a compact module is important. The panel is also built with a layered structure that supports stable output under real-world outdoor conditions. Its temperature behavior and robust construction make it suitable for mobile and fixed off-grid applications. The panel can be connected in a system using its integrated cable and quick connection hardware.
Solar conversion: Sunlight reaches the monocrystalline cells, which generate electricity through the photovoltaic effect. The 120 Wp rating reflects the panel's maximum power under standard test conditions.
Back-contact cell layout: The rear-side electrical contacts reduce surface obstruction on the front face. This helps make better use of the available cell area for light capture.
Thermal and structural support: The aluminium frame improves heat dissipation and adds rigidity. Tempered glass and EVA encapsulation help protect the module against environmental stress.
