315W JA BiFacial Solar Panels - 60 cell
These panels have a glass back sheet so they absorb sun which bounces back from behind the panel. Great for low light and cloudy conditions. These are ideally suited to boats with a white roof as you can see gains of upto 26% from the reflection of light back from the white surface making the panel 391W. Any surface will work, but white gives you the best refraction of light back to the panel, or you can add aluminium solar reflective paint on the roof under the panel to get the best gain.
If using this panel with MPPT you should calculate this panel as 400W so that you do no overload the MPPT. Tracer MPPT's have current limiting so it doesn't matter if you go over the rated amps, but Outback will be damaged by too much power.
JA bifacial modules are assembled by high-performance PERCIUM cells and encapsulated by glass-glass panels, are capable of converting energy from incident lights on front and diffuse light, as well as reflected and scattered light on rear sides, which make them better reliability, superior low irradiance performance, and excellent energy generation performance. Framed structure is benefit to module packaging transportation and installation, higher tolerance for harsh environment and extreme weather conditions.
