Yes, as long as you use an MPPT charge controller to step down the 33.5V to the correct charging voltage for a 12V battery.
No, this is a rigid panel featuring a tempered glass surface and an aluminium frame.
The parallel cell structure with five independent strings allows the panel to continue producing power even if a section is shaded.
Yes, the robust aluminium frame and tempered glass are designed to withstand the harsh conditions of marine environments.
Yes, you can wire multiple panels in parallel or series depending on your charge controller's input specifications.
Check the connections for corrosion and ensure no heavy debris or snow is blocking a large portion of the panel surface.
Verify that your wiring polarity is correct and that the open-circuit voltage does not exceed the controller's maximum input voltage rating.
For installation, ensure the panel is mounted using appropriate Z-brackets or mounting rails to account for the 35mm frame thickness. Due to its size (1546 mm x 825 mm), always verify roof load limits before installation on vehicles. The panel is designed for fixed mounting; avoid walking on the tempered glass surface. Periodically clean the glass with water and a soft cloth to maintain maximum efficiency, especially after exposure to dust, snow, or salt spray in marine environments. Always use correct gauge wiring and a compatible fuse between the panel and the charge controller to ensure electrical safety.
