This 30W monocrystalline solar panel is built for 12V battery charging in caravans, boats, motorhomes and off-grid systems where a higher and more consistent output is needed. Its 20V operating voltage supports efficient charging, while six pre-drilled mounting holes and a slim 25mm profile allow secure installation directly onto flat surfaces such as roofs and decks. An integrated blocking diode prevents reverse current from the battery back to the panel, supporting stable charging performance in low light and overnight.

The panel is made with tempered glass and a robust aluminium frame for long-term outdoor use in caravan, boat, motorhome and off-grid installations. Mount it where it receives maximum direct sunlight, using all six fixing holes to keep it secure in exposed positions. Clean the glass surface with a soft cloth and mild detergent to remove dirt and salt deposits, and inspect the frame, cable and connections periodically. Check the polarity before connecting the panel to a 12V battery or charge controller.
