Oswal Solar Structure OSWAL550MP144TB 550W Mono PERC Half-Cut Bifacial Solar Panel
OSWAL550MP144TB | Mono PERC Half-Cut | 144 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Oswal Solar Structure OSWAL550MP144TB is a premium 550W monocrystalline solar panel designed for high performance. It features advanced Mono PERC half-cut cell technology to maximize energy conversion. This bifacial module captures sunlight from both front and rear sides. The anti-reflective glass coating enhances solar energy absorption significantly. Built with anodized aluminum frames, it ensures long-term durability in harsh weather. The panel offers a 30-year linear power warranty for sustained output. Its 21.32% efficiency rating makes it ideal for large-scale commercial projects. This Made in India product meets rigorous international quality standards. The split junction box provides IP68 weatherproof protection for safety. It supports a maximum system voltage of 1500V for flexible grid integration.
Key Benefits
High Bifacial Gain: Captures reflected light from the rear to boost total power output by up to 26%.
PERC Technology: Passivated Emitter Rear Cell design reduces electron loss for higher energy conversion efficiency.
Half-Cut Cells: Reduces internal resistance and minimizes hot-spot risks under partial shading conditions.
Long Warranty: Includes a 12-year product warranty and a 30-year linear power warranty for reliability.
Robust Construction: Features tempered glass with anti-reflective coating and a strong anodized aluminum frame.
How It Works
This solar panel converts sunlight into electricity using the photovoltaic effect within its 144 cells. The Mono PERC technology creates a rear passivation layer that reflects unused light back into the cell. This process increases the absorption of photons and boosts overall electrical current generation. The half-cut cell design splits each cell to lower resistance and improve performance. Bifacial capability allows the rear side to harvest albedo light from the ground or surrounding surfaces. This dual-sided absorption significantly increases total energy yield compared to standard monofacial panels.
Photovoltaic Conversion: Sunlight hits the silicon cells, exciting electrons to create a flow of direct current electricity. This process happens instantly whenever photons strike the semiconductor material.
Bifacial Energy Capture: The rear side of the panel absorbs reflected light from the installation surface. This extra energy input increases the total power output significantly beyond front-side limits.
Shade Resistance: Half-cut cells reduce the impact of shading on individual sections of the panel. The multi-busbar technology ensures current flows efficiently even when parts of the panel are blocked.
