The JA Solar 385W Mono MBB PERC Half-Cell Black Short Frame MC4 (JAM54S31 390-415/MR) solar panel is a 4000W monocrystalline module with 120 Half-Cell technology. JA Solar offers a high-efficiency module with PERC cells, which, thanks to its half-cell configuration, offers high power output, better temperature coefficient, lower efficiency loss against shading, and higher resistance to mechanical loads. JA solar panels come with a 12-year product warranty and a 25-year linear output warranty.

Ideal for off-grid photovoltaic solar energy installations, these panels stand out for their incredible quality/price ratio and their great power in a small size.

THIS PRODUCT HAS A MINIMUM ORDER QUANTITY OF 4

Features:

  • SUPER HIGH EFFICIENCY PERC MODULE: Assembled with 11 BB PERC cells, the half-cell configuration of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on energy generation, lower risk of a hot spot, as well as enhanced tolerance to mechanical loading.

  • DURABLE, DUST & WATER RESISTANT: JA Solar's monocrystalline modules offer an excellent response even in extreme temperature conditions or low solar radiation, such as on cloudy days, at dawn, or dusk. The advanced, textured glass surface of the photovoltaic cells offers unsurpassed resistance to high levels of sea salt, ammonia, dust, or sand.

  • MORE RELIABLE (THE PANEL USES BUILT-IN HALF-CUT CELL TECHNOLOGY):
    • Lower internal current, lower hot spot temperature
    • Cell crack risk limited to a smaller area of the cell
    • Innovative symmetrical module design means better shading tolerance
    • Heavy snow load up to 5400Pa and increased wind load up to 2400Pa
  • SUPERIOR WARRANTY: 12-year product warranty and 25-year extra linear power output warranty.

Must be installed by a licensed technician or electrician.

    Frequently Asked Questions

    HOW GOOD IS THE JA SOLAR PANEL?

    JA Solar panels are relatively inexpensive, with prices comparable to Trina Solar, LONGi Solar, and Canadian Solar. Their average efficiency ranges from 20% to 21%, placing JA panels among the most efficient in their price range. Additionally, these panels are highly durable and exhibit good shading tolerance.

    WHO MANUFACTURES JA SOLAR PANELS?

    JA Solar Holdings is a solar development company based in the Yangpu district, Shanghai. Established in 2005, the company designs, develops, manufactures, and sells solar cell and solar module products. JA Solar operates globally, selling its products in 135 countries and regions. Recognized for technological innovation, financial stability, and a robust global sales and customer service network, JA Solar is esteemed as a leading global manufacturer of high-performance PV products.

    WHAT IS THE PRODUCTION CAPACITY OF JA SOLAR MODULES?

    As of the end of 2022, JA Solar reported module orders totaling 25.47 GW, primarily comprising 182mm size. During January and February 2023, the company had already shipped 6.7 GW. The module production capacity until the end of 2022 was nearly 50 GW, with wafer and cell capacity at approximately 80% of the module capacity.

    WHAT CURRENT CLASS IS JA SOLAR?

    JA Solar modules have been classified as Class A according to the IEC 61730-2 standard. For roof installations, modules should be mounted over a fire-resistant covering suitable for this application, with adequate ventilation between the modules backsheet and the mounting surface.

    IS JA SOLAR TIER 1?

    Yes, JA Solar is classified as a Tier 1 solar panel manufacturer, joining the ranks of Jinko Solar, LONGi, Trina Solar, and Canadian Solar.

    WHAT ARE THE TIER 1 SOLAR PANELS?

    Tier 1 solar panels are crafted using the highest quality silicon. Higher silicon quality enhances the panel's effectiveness. Additionally, Tier 1 manufacturers employ advanced robotic methods to regulate the production process, reducing or eliminating human mistakes.

    HOW LONG DO TIER 1 SOLAR PANELS LAST?

    Tier 1 solar panels come with an industry-standard warranty of 25 years or longer. In practice, these panels often outlast this period, ensuring efficiency above 80% of their rated capacity after 25 years.

    WHAT IS JA SOLAR MBB PANELS?

    MBB stands for Multi Busbar, indicating that a solar cell is equipped with 12 or 16 busbars instead of 4, 5, or 6. This configuration results in higher power output and greater reliability, with a power increase of approximately 2% to 2.5%.

    WHAT IS MBB HALF CELL MODULE?

    Assembled with multi-busbar PERC cells, the half-cell configuration offers advantages such as higher power output, better temperature-dependent performance, reduced shading effect on energy generation, lower risk of hot spots, and enhanced tolerance for mechanical loading.

    WHAT IS THE EFFICIENCY OF JA SOLAR PANELS?

    The efficiency of JA Solar panels typically ranges between 20% and 21%, which is above average in the market. JA Solar engineers incorporate popular modern solar technologies, including half-cut cell construction, PERC cell technology, and busbars.

    ARE HALF-CELL SOLAR PANELS BETTER?

    Yes, half-cell modules are more efficient and reliable than their full-cell counterparts. They can lead to time and cost savings for installers by delivering more power per square meter, requiring fewer panels to generate the same power.
