The Voltaic P121 2V 0.3W Mini Solar Panel provides high-performance solar power in a lightweight form, ideal for IoT applications with strict size and reliability requirements.
The Voltaic P121 is a 52x52mm high-performance 2V 0.3W Mini ETFE solar panel designed for industrial IoT applications, offering a lightweight, efficient, and cost-effective solution for outdoor power.
SMT ETFE panels are advantageous where size or weight is constrained, long lifetimes are required, and strict quality and dimensional tolerances must be maintained. They do not come with a pre-installed cables, these panels require soldering.
Voltaic ETFE panels are manufactured using a strictly sourced and qualified material stack. They are third-party tested for the equivalent of over 10 years of UV exposure, along with thermal cycling, vibration stress, and resistance to chemicals and oils.
They are also used in a number of ATEX applications, demonstrating suitability for demanding and hazardous environments.
Please note this is special 2V solar panel for custom builds. It is unlikely to work in the majority of our solar management boards, as these usually require at least 5-6V.
