• Smaller panel size
• Lower power consumption
• Compact Arduino/IoT project
• Low-current battery charging experiment
• Lightweight portable setup
Choose the 3W / 500mA version if your project requires:
• Higher available solar power
• Faster charging potential
• Higher current output
• Larger project load
• More reliable output under good sunlight
How to Use / ব্যবহার পদ্ধতি
The solar panel produces DC voltage when exposed to sunlight.
Basic connection:
🔴 Red Wire → Positive (+)
⚫ Black Wire → Negative (-)
For direct electronics projects, use a suitable voltage regulator or DC converter if required.
For battery charging, use a proper solar charge controller / charging circuit suitable for your battery type.
⚠️ Do not connect rechargeable lithium batteries directly to the panel without a proper charging circuit.
Solar Output Note
The stated voltage, current and wattage are nominal/rated values.
Actual output depends on:
• Sunlight intensity
• Panel angle
• Weather condition
• Temperature
• Shade
• Load resistance
• Wiring loss
Under cloudy weather or indoor lighting, output will be much lower than the rated value.
