5V 120mA Monocrystalline Solar Panel, Compact Efficiency for DIY Electronics Projects

120 mm x 30 mm Monocrystalline Solar Panel Module 5 V 120 mA Compact, reliable solar module that converts sunlight into lowvoltage DC power for small electronics and DIY projects. Key benefits Compact power source: Small footprint fits into tight spaces and portable projects while delivering a nominal 5 V at up to 120 mA. Efficient monocrystalline cells: Monocrystalline silicon construction provides higher efficiency per area than many alternatives, making the most of available sunlight in a small module. Easy to integrate: Module form factor simplifies mounting and wiring into prototypes, sensor enclosures, small chargers, or teaching kits. Predictable performance: Rated output of 5 V and 120 mA gives a clear baseline for selecting compatible regulators, battery chargers, or load requirements. What it does and how it solves problems Converts sunlight directly to DC power suitable for lowpower electronics, minimizing the need for mains power in remote or mobile setups. Provides a compact, lightweight power source for maintaining or supplementing battery charge when paired with an appropriate charge controller or regulator. Reduces wiring and power management complexity for small installations by supplying a stable nominal voltage for downstream regulation. Important attributes Function: Photovoltaic module producing a nominal 5 V DC output at up to 120 mA under standard lighting conditions. Compatibility: Suitable for lowcurrent electronics, microcontroller projects, offgrid sensors, small LED lighting, and battery maintenance when used with appropriate electronics such as voltage regulators, boost converters, or charge controllers. Size: 120 mm by 30 mm footprint, well suited for compact enclosures and panel arrays where space is limited. Material: Monocrystalline silicon cells assembled into a finished module for direct use in projects. Performance: Approximately 0.6 W nominal output under sunlight conditions; actual output will vary with light intensity, angle, and temperature. Practical use scenarios Remote sensor node: Power a lowpower environmental sensor or data logger with the module plus a small rechargeable battery and charge management circuit to maintain operation between maintenance visits. Portable charger for small devices: Combine the module with a regulated 5 V boost or buck converter and a battery buffer to create a simple solarpowered USB charging solution for lowcurrent devices. Educational and prototype projects: Use as a classroom demonstration component or in hobbyist builds to teach photovoltaic principles and to power microcontroller boards and LED circuits. Installation tips Mount with a clear view of the sun and at an angle appropriate for your latitude to maximize daily energy harvest. Use a suitable blocking diode or charge controller when connecting to batteries to prevent reverse discharge. Match the module output to regulators and batteries so that voltage and current ratings are respected for safe, reliable operation. This small monocrystalline module provides a convenient, efficient solar power option for lowpower applications and compact projects that require a predictable 5 V nominal supply at modest current.
