    JA Solar 385W Solar Panel – Monocrystalline Panel – JAM72S03 360-385

    JA Solar has been leading the market in high-performance solar panels since 2005. Their panels are used in huge numbers in residential, commercial, and municipal power generation projects all over the world. This is a large single panel, so it’s perfect for higher capacity electrical systems in vans, boats, and off-grid houses. The panel is pre-wired with MC4 connectors, and the sturdy aluminium frame is easily compatible with a variety of mounting systems.

    High Tech and High Performance

    The JA Solar 385W solar panel is the culmination of intense R&D from a manufacturer with years of expertise behind them. Assembled with high efficiency PERC cells, the half cell configuration of the modules in the panel offers the following advantages:

    • higher power output
    • better temperature dependent performance
    • reduced shading effect on energy generation
    • lower risk of hot spots
    • enhanced tolerance for mechanical loading

    The cells are monocrystalline, i.e. the manufacturer has cut them from a single sheet of silicon. This uniformity greatly contributes to their superior efficiency.

    PERC Cells

    PERC technology is new on the market; it only emerged in 2018. The JA Solar 385W solar panel incorporates this cutting-edge tech. Thus, you won’t find a panel construction with a higher solar power conversion efficiency on the market today. An extra layer at the back of the cell means PERC technology improves light capture, optimises electron capture, and reduces heat generation.

    The High Open Circuit Voltage that You Need for Your System

    As detailed on our solar panel guidebook page, open circuit voltage (Voc) is an important and oft-overlooked factor. Most AGM or lithium leisure batteries require a Voc of around 14V. Voc drops by the same percentage as solar power generation performance. Thus, if your panels are only working at 50% of their capacity (on a cloudy day, for example), this correspondingly cuts your Voc by 50%. This JA Solar 385W solar panel has a high Voc of 48V, so your batteries will charge effectively even at a lower performance threshold. Winter or summer, rain or shine, it’ll be one less thing to think about.

    Solar panel mounting options

    Depending on your application, the JA Solar 385W solar panels can be mounted in a number of ways. If you have a roof rack you can mount directly to this. Otherwise, you can use mounting brackets to attach your solar panels to the roof of your campervan.
