Compact polycrystalline solar panel for DIY and smallscale solar projects Key benefits Spacesaving size: at 80mm x 40mm, this mini panel fits into tight layouts and small enclosures without sacrificing build quality. Durable construction: made from polycrystalline silicon and encapsulated in epoxy resin to resist weather exposure and mechanical stress in outdoor and semioutdoor settings. Practical power source: designed to supply steady power to lowpower devices and small solar systems, making it easy to add solar capability to a range of projects. What it does and why you need it Provides a reliable, compact source of solar energy for hobby and prototype applications where fullsize panels are impractical. Solves space and durability challenges by combining a small footprint with a robust encapsulation that helps protect the cells from environmental wear. Makes it simple to integrate solar charging or direct solar power into pumps, sensors, lighting, and other lowpower equipment. Features and specifications Size: 80mm x 40mm, suitable for small enclosures and modular builds. Cell type: polycrystalline silicon for consistent performance in small modules. Encapsulation: epoxy resin casing for improved resistance to moisture and impact. Intended use: powering devices such as small solar water pumps and components in small solar systems. Compatibility and function Compatible with small charge controllers, battery packs, and directdrive lowpower devices commonly used in DIY solar setups. suited for lowcurrent, lowvoltage applications and systems where multiple panels can be combined for higher output. Practical use scenarios Garden water feature: power a small solar water pump to run a tabletop fountain or birdbath pump without routing mains power. Remote sensor or weather station: keep a lowpower sensor or data logger running in a location without convenient AC power by adding this panel and a small battery. Outdoor lighting and camping: integrate into compact lighting modules or portable chargers for camping, patios, or yard lighting where portability and durability matter. Summary This mini solar panel offers a compact footprint, durable epoxyencased polycrystalline construction, and straightforward compatibility with small solar systems and lowpower devices. It is a practical choice for DIY projects, outdoor gadgets, and any application that requires a small, weatherresistant solar power source.
