  • Bifacial Energy Yield

    The bifacial technology enables additional power generation from the back of BiMAX4 modules (up to 25%), and brings a high efficiency (up to 21.63%), which has been verified by customers and third-party testing organizations.

  • Robust Double Glass Construction

    The robust double glass construction of BiMAX4 modules not only increases resistance to environmental influences, but also extends the lifespan of the modules, with an annual power degradation of less than 0.45%.

    • Q

      What type of module is better for my application, monofacial or bifacial?

      A

      Choosing between monofacial and bifacial modules depends on various factors such as installation location, available space, budget and environmental conditions. Bifacial modules offer higher power generation potential compared to monofacial modules, making them slightly more expensive. However, their ability to capture light from both sides, especially when unobstructed, significantly enhances energy yield. Additionally, the glass-glass encapsulation structure provides better resistance to environmental factors like water vapor and salt-air fog. Monofacial modules are better suited for installations in mountainous regions and rooftop applications where space is limited.

    • Q

      Does the PERC BiMAX4 bifacial double glass solar modules offer high efficiency?

      A

      Yes! Sunpal's PERC BiMAX4 bifacial double glass solar modules are known for their high efficiency. With power outputs ranging from 355W to 470W, these modules utilize advanced Mono PERC technology, bifacial design and half-cut technology to achieve higher performance and better energy yield.
