The REC Alpha Pure RX 400W Solar Panel represents the next generation of high-efficiency solar technology, crafted for superior performance, durability, and style.
Engineered with REC’s advanced HJT (Heterojunction) cell technology, this panel delivers maximum energy output per square meter and maintains excellent performance even under extreme weather conditions in Bangladesh.
Whether for residential rooftops, commercial buildings, or solar-powered farms, this panel guarantees consistent power generation and long-term reliability.
At the heart of the REC Alpha Pure RX 400W is its Heterojunction (HJT) technology – a hybrid design that combines crystalline and thin-film solar cells to achieve higher efficiency and better temperature tolerance.
Key Benefits:
✅ No Light-Induced Degradation (LID): Your panel produces full power from day one.
✅ Better High-Temperature Performance: Maintains high output even in hot Bangladeshi summers.
✅ Higher Lifetime Yield: Generates up to 10% more power over its lifetime compared to conventional mono panels.
✅ Eco-Friendly Manufacturing: Lead-free and low-carbon production.
This technology ensures maximum efficiency even on cloudy or humid days, making it perfect for tropical regions like Bangladesh.
The REC Alpha Pure RX 400W offers an impressive 22.8% efficiency and 230 W/m² power density, making it one of the most space-efficient panels in the world.
Its gapless cell layout and innovative busbar design allow more sunlight absorption per module, resulting in higher daily power production — ideal for both urban rooftops and large-scale installations.
Performance Advantages:
Higher energy generation per m²
Optimized for rooftops with limited space
Excellent low-light performance
Stable output under shading conditions
Beauty meets power. The REC Alpha Pure RX 400W comes in a sleek full-black finish, giving your solar installation a modern, minimalist look that enhances rooftop appearance.
Design Features:
Gapless Full-Black Cell Layout for a seamless look
Micro-Wire Connection for maximum current flow and minimal resistance
Split-Cell Layout (Twin Design) ensures continuous generation even under partial shading
Durable Frame (30mm Height) with high mechanical load strength (up to 7000 Pa)
This makes it perfect for homeowners and architects who value both style and performance.
