Mini Solar panel 100 x 60 mm 5V 150mA Solar Panel Cell Module Charger USB 5V 0.75W

Mini Solar Panel (100 x 60 mm, 5V 150mA, 0.75W) is a compact, high-efficiency polycrystalline photovoltaic module designed to harvest clean solar energy for low-power electronic applications. Encapsulated with protective waterproof PET film, this lightweight panel generates up to 5V DC and 150mA under optimal sunlight conditions. It is an ideal, eco-friendly energy solution for charging single-cell Li-ion/LiPo batteries, powering low-power microcontrollers (Arduino, ESP32, ESP8266), driving small DC motors, and operating outdoor IoT remote weather nodes.

Features

• Compact 100mm*60mm form factor easily integrated into portable enclosures and DIY gadgets
• High-efficiency polycrystalline solar cells providing reliable energy conversion even in partial outdoor lighting
• Tough PET film surface encapsulation offering water resistance, UV protection, and scratch durability
• Pre-tinned rear solder pads for easy attachment of wires, jumper cables, or USB female connector breakout boards
• Standard 5V DC nominal output directly suitable for USB power rails and 3.7V lithium battery charging circuits (TP4056)
• Lightweight and portable construction perfect for wearable electronics, outdoor sensors, and field equipment
• Eco-friendly renewable energy source ideal for off-grid environmental monitoring and STEM learning projects
• Maintenance-free solid-state operation with no moving parts

Applications

• Charging 3.7V Li-ion/LiPo batteries via TP4056 solar charger modules
• Powering remote IoT environmental sensors, weather stations, and agricultural soil monitors
• DIY solar-powered toys, mini solar cars, light-chasing robots, and science fair models
• Solar emergency night lights, garden accent lighting, and small power bank tricklers
• Polytechnic diploma, university engineering thesis, and renewable energy educational projects

Important Notes:

• Sunlight Requirement: Solar panels require direct, unfiltered sunlight to achieve full rated power output (5V, 150mA). Indoor fluorescent or LED room lighting will produce negligible current.
• Battery Charging Circuit: Do not connect the solar panel output directly to a rechargeable lithium battery without a dedicated charge controller (such as a TP4056 module) to prevent overcharging or voltage instability.
• Soldering Caution: When soldering lead wires onto the back copper pads, use a quick soldering touch (around 300°C for 2–3 seconds) to prevent thermal damage to the underlying solar cell trace layers.
• Maintain proper polarity when wiring: Plus (+) indicates positive VCC, and Minus (-) indicates Ground (GND).

Package includes

• 1 x Mini Solar Panel (100 x 60 mm, 5V 150mA 0.75W)
