User Guide: How to Use This Solar Panel

To get the most out of your Bigyan Project solar panel, follow these simple steps:

• Position the solar panel in direct sunlight at a 90-degree angle to the sun for optimal performance
• Connect the positive (red) and negative (black) wires to your device or battery
• For charging batteries, ensure the battery voltage matches the panel's output
• To increase voltage, connect multiple panels in series (positive to negative)
• To increase current, connect multiple panels in parallel (positive to positive, negative to negative)
• Use a charge controller when charging lithium batteries
• Clean the panel surface regularly with a soft cloth to maintain efficiency
• Store in a dry place when not in use for extended periods

Frequently Asked Questions (FAQs)

• Can this solar panel charge a smartphone directly? While it can technically provide power, the 0.75W output is too low for efficient smartphone charging. We recommend using it with a power bank or for emergency charging only
• What is the difference between polycrystalline and monocrystalline? Polycrystalline panels are slightly less efficient but more cost-effective, making them ideal for educational and hobby projects
• How long does it take to charge a 3.7V lithium battery? Charging time depends on battery capacity and sunlight conditions. A typical 1000mAh battery would take about 15 hours in ideal conditions
• Is this waterproof? The epoxy encapsulation provides water resistance, but we don't recommend complete submersion
• Can I connect multiple panels together? Yes, you can connect up to 4 panels in series or parallel for different applications

Challenges and Considerations

• Output varies significantly based on sunlight intensity and angle
• Not suitable for high-power devices or fast charging
• Requires proper wiring and connections for optimal performance
• May need additional components (diodes, regulators) for certain applications
• Performance decreases slightly over time (typical 0.5% per year)

Compatibility Information

• Works with most 3.7V-5V battery systems
• Compatible with Arduino, Raspberry Pi, and other microcontroller projects
• Can be used with common 5V USB devices (with proper current regulation)
• Pairs well with small DC motors and LED lighting systems
