Raymarine Solar Panel f/Hull Transmitter

The Raymarine Solar Panel for Hull Transmitter (Model T138) is a compact renewable energy solution designed to continuously power Raymarine Micronet wireless systems on the water. This small-footprint solar panel supplies power to Micronet T121 Hull Transmitters and T122 Wireless NMEA Interface units, eliminating the need for frequent battery replacements and reducing ongoing maintenance demands on modern marine electronics installations.

The panel's efficient solar cells capture ambient light throughout the day, converting it into consistent electrical output to keep your Micronet system operational in all conditions. At just 4 x 1 x 4 inches and weighing only 0.3 lbs, the solar panel integrates into deck installations without adding significant weight or visual clutter. Installation splays are engineered for fast, straightforward mounting on hull surfaces or cabin tops where direct sunlight exposure is reliable. The compact design makes it ideal for systems where permanent power lines are impractical or where boat owners want to reduce reliance on internal battery reserves.

Raymarine T138 solar panels suit cruising sailors, offshore anglers, and weekend boaters who operate Micronet-equipped vessels and want extended runtime between service intervals. The panel is particularly valuable on larger sailboats with mast-mounted wind instruments and hull-mounted wind sensors that rely on continuous power, as well as on fishing boats running wireless weather and navigation systems. Owners of older Micronet systems that lack built-in rechargeable power sources will find this panel extends the operational life of their electronics significantly.

Raymarine has established itself as a leader in marine electronics, and this solar solution reflects the brand's practical engineering approach—focusing on reliability in salt-air environments and ease of field installation. The T138 pairs seamlessly with existing Micronet hardware and requires no software configuration, making it an accessible upgrade for any boat already running Raymarine wireless instruments.
