Compact 6V 320mA Polycrystalline Solar Panel for DIY Battery and Phone Projects This small, reliable solar panel delivers a rated output of 6V and 320mA for 1.92W of power in a compact 140 x 104 mm form factor. Its polycrystalline cells are suited for hobby electronics, portable charging projects, and small offgrid systems where space and weight are limited. Key benefits Portable and spacesaving: small footprint makes it easy to integrate into backpacks, custom power banks, or compact enclosures. Ready for DIY projects: designed for hobbyists and makers building battery chargers, phone power packs, and small DC devices. Predictable power output: rated 6V and 320mA provides a clear starting point for designing charging circuits or matching to boost converters and charge controllers. Durable cell material: polycrystalline construction balances cost and efficiency for steady performance in typical sunlight conditions. Important attributes Function: provides lowvoltage DC power suitable for charging small rechargeable battery packs and powering lowconsumption electronics when paired with appropriate charging or voltage regulation circuitry. Compatibility: suitable for use with battery charging circuits, boost converters, hobby electronics, small USB power modules, and other DIY solar systems intended for cell phone charging or battery maintenance. Use with the correct charge controller or regulation module to protect batteries and devices. Size: 140 x 104 mm, compact for easy mounting and integration into small projects. Material: polycrystalline solar cells for reliable performance in a compact panel. Performance: rated output 6V, 320mA, 1.92W under standard test conditions. Practical use scenarios Portable power bank build: integrate the panel with a small charge controller, battery cell, and USB boost module to create a solarassisted phone charging pack for travel or emergency use. Battery maintenance and trickle charging: use the panel as part of a maintenance charger for small rechargeable packs to keep them topped up when stored, using an appropriate charge controller to prevent overcharge. Small offgrid electronics: power sensors, LED lights, or lowpower microcontroller projects in garden, camping, or remote monitoring applications where a compact panel is preferred. What to consider when integrating Use a proper charge controller or voltage regulation module to match the panel output to battery chemistry and prevent overcharging. Realworld current and voltage depend on sunlight, panel orientation, and temperature. Design your circuit with some margin below the rated 320mA. Combine multiple panels in series or parallel only if your application and wiring accommodate the resulting voltage or current, and use appropriate balancing or protection components. This compact 6V 320mA polycrystalline panel is a practical component for DIY solar chargers, portable power solutions, and small electronic projects that need a reliable, spaceefficient solar source.
