The Voltaic P108 18V 9W Solar Panel delivers reliable outdoor power with high-efficiency cells, an IP67-rated ETFE build, and easy mounting for long-term use. The Voltaic P108 is a 22.3x27.4cm, 18V 9W solar panel for reliable off-grid power. Built with high-efficiency monocrystalline cells rated at 20%, it provides consistent energy output in a lightweight form factor suitable for long-term outdoor installations. An ETFE coating protects the panel surface, offering resistance to UV exposure and scratches while maintaining strong light transmission. Combined with its IP67 waterproof rating, the panel is designed to withstand harsh environmental conditions, making it suitable for permanent mounting in exposed locations. Installation is straightforward thanks to six mounting holes and optional mounting brackets (sold separately). A pre-attached 50cm cable with a waterproof 3.5 × 1.1mm connector allows for secure power delivery, with extension options available for flexible setups. For maximum performance, the panel should be positioned directly towards the sun. With a peak power output of 9.92W and stable voltage characteristics, the P108 is well suited to powering low-power electronics, charging systems, and remote monitoring applications where reliability and efficiency are essential.
