Share:

  • Superior Energy Conversion

    Driven by advanced N-type 182*210 mm cells, the SP625M-66H module achieves a peak efficiency of up to 23.14%. Engineered for thermal stability, it features a Leading Temperature Coefficient of -0.29%/°C, ensuring minimal power loss even in high-temperature environments. This technical superiority allows it to generate significantly more electricity per square meter than traditional P-type PERC modules, maximizing the system's output and long-term profitability.

  • Optimized Low-Light Performance

    This module excels in challenging environments thanks to its High Bifaciality (80-85%), which captures significantly more reflected light from the rear side. This optical advantage ensures optimal efficiency even in low-light conditions such as cloudy days, early mornings, or shaded areas. By harnessing ambient albedo, it maintains consistent power generation, making it ideal for urban, residential, or shaded installations where standard modules fall short.

    • Q

      What is the efficiency rating of SUNPAL Topcon Dual Glass Solar Panels?

      A

      These panels boast a high efficiency rating of up to 23.36%, meaning they can convert more sunlight into usable energy compared to lower-efficiency panels.

    • Q

      What is the temperature coefficient of these solar panels?

      A

      This BiMAX N-type module features an industry-leading temperature coefficient of -0.29%/°C. Unlike standard P-type modules (typically -0.35%/°C), this lower coefficient means the panel loses significantly less power as temperature rises. This ensures stable and high energy yield even in extreme heat environments, making it ideal for hot climates. Detailed performance curves are available in the datasheet.

    • Q

      How do these solar panels contribute to sustainability?

      A

      By choosing SUNPAL Topcon Dual Glass Solar Panels, you're investing in clean and renewable energy, reducing your carbon footprint, and contributing to a greener future.

    • Q

      Are SUNPAL Topcon Glass Glass Solar Panels easy to install?

      A

      While it's recommended to hire a certified solar installer, these double glass solar panels are designed for straightforward installation with standard mounting systems.
