Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Bifacial Energy Conversion: The BLUESUN solar cell efficiently converts sunlight into electricity using PERC (Passivated Emitter and Rear Cell) technology, optimized for both front and rear light absorption.
  • BIPV Integration: Designed for Building-Integrated Photovoltaics (BIPV), it seamlessly integrates into facades and rooftops, combining energy generation with architectural aesthetics.

Key features

  • 1. Bifacial PERC Silicon Cells for Dual-Sided Energy Capture

    • With bifacial PERC silicon cells, you can capture sunlight from both sides for up to 25% higher energy yield compared to traditional monofacial panels*. This technology maximizes efficiency in environments with reflective surfaces or indirect light.

  • 2. High-Transmittance Design for Building-Integrated Applications

    • With >50% light transmittance, you can maintain natural light transmission while generating electricity for facade installations, making it ideal for modern architectural designs*.

  • 3. Versatile Power Output for Diverse Use Cases

    • With 4W-6W output options, you can meet small-scale energy needs for residential rooftops or commercial facades, offering flexibility compared to larger, less adaptable panels*.

  • 4. 4mm Tempered Glass for Enhanced Durability

    • With 4mm thick tempered glass, you can ensure resistance to environmental impacts like hail or debris, outperforming thinner panels in harsh conditions*.

  • 5. Comprehensive EPR Compliance for European Market Readiness

    • Equipped with EPR certifications in Germany and France, you can streamline regulatory compliance for easy market entry in Europe while adhering to strict environmental standards*.

Supplier's note

  1. Technical Breakthroughs:

    • Bifacial PERC Technology: Captures sunlight from both sides, boosting energy yield by up to 30% in reflective environments.
    • >50% Transmittance: Outperforms standard panels (typically 40–45%) for low-light efficiency.
    • EPR Compliance: Simplifies market entry across Europe with full regulatory alignment.

  2. Version Selection Guide:

    • Base Model (4W): Ideal for small residential rooftops or low-power BIPV projects.
    • Advanced Model (5W): Perfect for mid-sized facades or commercial rooftops needing moderate power.
    • Pro Model (6W): Delivers 22% efficiency—20% higher than industry standards—making it optimal for large-scale commercial installations requiring peak performance.

With bifacial technology, you can double energy capture in urban settings. Pair the Pro Model’s 22% efficiency with its lightweight design for seamless integration into high-rise facades, reducing carbon footprints while enhancing aesthetics.
