Polycrystalline Solar Panels

These polycrystalline solar panels offer a range of power outputs suitable for everything from small educational kits to more advanced IoT and off-grid electronic systems. Available in 5.5V 0.38W, 5V 2W, and 12V 3W configurations, they provide clean, renewable energy for a wide variety of low-voltage DC applications. Whether you’re building a solar-powered Arduino project, charging batteries, or setting up an outdoor sensor, these panels deliver reliable performance in a compact form factor.

Built with durable epoxy resin coatings and rigid backing, each panel is designed for long-term use in indoor and outdoor environments. Their compact sizes and pre-soldered terminals (varies by model) make them easy to integrate into DIY, educational, or experimental projects.
