5 Pack Mini Solar Panels 5V 250mA 1.25W 110mm x 69mm (4 x 2.7 in) Compact photovoltaic modules designed for DIY projects, small solar systems, and educational kits. Each panel produces up to 5 volts and 250 milliamps under standard sunlight conditions for a nominal output of 1.25 watts. Key benefits Ready supply of lowvoltage DC power for small electronics and experiments. Compact size fits into models, toys, and tight enclosures where larger panels are impractical. Sold as a set of five panels to support multipanel configurations or multiple projects. Simple integration with common hobby electronics and solar controllers to support safe battery charging and device operation. Product highlights and specifications Quantity: 5 panels per pack. Output: 5 V nominal, 250 mA, 1.25 W per panel. Size: 110 mm x 69 mm (4 x 2.7 in) per panel. Function: Photovoltaic solar cell module for converting sunlight into DC power. Use: Intended for DIY solar power, toy materials, photovoltaic experiments, and small system kits. Compatibility and performance notes Suitable for hobby electronics, microcontroller projects, small LED lighting, and educational demonstrations. Can be connected in series to increase voltage or in parallel to increase current when designing larger arrays. For battery charging or powering devices, use an appropriate charge controller or regulator to match battery type and device requirements. Practical use scenarios 1. STEM and classroom projects Power sensors, LED circuits, and small motors in handson lessons that demonstrate solar energy principles. 2. Small offgrid kits and hobby builds Integrate into model boats, garden lighting prototypes, or remote sensors where compact solar panels are needed. 3. DIY charging and experiments Combine multiple panels to experiment with voltage and current scaling, or connect to a charge controller to test small battery charging setups. Integration tips Verify sunlight exposure and panel orientation for output. Use diodes or blocking diodes when combining panels to prevent reverse current at night. Employ a suitable charge controller or voltage regulator when charging batteries or powering sensitive electronics.
