Raymarine Solar Panel f/Hull Transmitter

Keep your Raymarine Micronet wireless network instruments powered up and ready for any adventure on the water with the compact T138 solar panel. Designed specifically for hull-mounted transmitters like the T121 or T122 Wireless NMEA Interface, this solar solution delivers reliable, maintenance-free power straight from the sun. No more worrying about dead batteries during long offshore trips or extended anchoring—simply mount it on your hull and let nature do the work.

Why Choose the Raymarine T138 Solar Panel for Your Boat?

Boat owners know the frustration of unreliable power sources disrupting critical data from wind gauges, speed logs, or depth sounders. The T138 steps in as a game-changer, providing a steady 9-volt trickle charge to keep your Micronet system humming. Its small 4-1/4 by 4-1/4 inch footprint means it blends seamlessly into your hull design without adding drag or clutter. Paired with a 10-foot cable, installation is straightforward, even in tight spaces below the waterline.

Engineered by Raymarine, a name synonymous with marine toughness, this panel withstands pounding waves, UV exposure, and salt spray. It's not just about power—it's about peace of mind, ensuring your wireless instruments stay connected and accurate when you need them most, whether racing competitively or cruising leisurely.

Standout Features That Deliver Real-World Performance

• Compact and Low-Profile: Minimal size reduces hydrodynamic impact and fits on most hull shapes.
• 9-Volt Output: Perfect match for Micronet hull transmitters, optimizing charge efficiency.
• Extended 10-Foot Cable: Offers flexible routing options for clean, hidden installations.
• Rugged Marine Build: Proven in extreme conditions with corrosion-resistant materials.
• Easy DIY Setup: No special tools needed—adhere, connect, and sail.

Boost Your Boating Experience: Key Benefits

Integrating the T138 solar panel transforms how you manage onboard electronics. It eliminates the need to run power cables from your main battery bank, reducing wiring complexity and potential failure points. Ideal for sailboats, power yachts, or dinghies where space and simplicity matter, it supports wireless data transmission for speed, depth, wind, and GPS—keeping your cockpit displays live without interruption.

Users rave about its longevity: in sunny climates, it fully charges the transmitter's internal battery daily, even on overcast days providing enough to maintain operations. Pair it with Raymarine's ecosystem for a fully wireless setup that's as reliable as it is innovative.

Simple Installation Tips for Optimal Results

Mount the panel on a southward-facing (in the northern hemisphere) section of the hull above the waterline for maximum sun exposure. Clean the surface thoroughly, apply marine-grade adhesive, and secure the cable with zip ties or conduit to avoid chafe. Connect directly to your T121 or T122—no regulators needed, as it's optimized for the system's NiMH battery. Test in shallow water before heading out to confirm charging.

Pro tip: In high-vibration areas, add a dab of silicone sealant around edges for extra hold. Regular rinses with fresh water keep it performing like new season after season.

Perfect Compatibility with Raymarine Micronet

Exclusively tailored for Raymarine's Micronet Wireless Network Instruments, the T138 powers the T121 Hull Transmitter (for speed/depth) and T122 Wireless NMEA Interface (for bridging NMEA 0183 data). It integrates flawlessly with tridata displays, wind systems, and autopilot interfaces, creating a cable-free network across your vessel.
