4.1 Identifying Solder Points

Each panel has clearly marked positive (+) and negative (-) solder points on its reverse side. Ensure correct polarity when making connections to avoid damage to the panel or connected devices.

4.2 Electrical Connections

• Soldering: Use appropriate soldering techniques to connect wires to the positive and negative terminals. Ensure strong, clean solder joints.
• Series Connection: To increase the output voltage, connect multiple panels in series (positive of one panel to negative of the next). For example, two 2V panels in series will provide 4V.
• Parallel Connection: To increase the output current, connect multiple panels in parallel (positive to positive, negative to negative). For example, two 160mA panels in parallel will provide 320mA.
• Combined Connections: Panels can be connected in a combination of series and parallel to achieve desired voltage and current outputs for your specific application.

4.3 Optimal Placement

For maximum power generation, position the solar panels in direct sunlight. Avoid shaded areas, as even partial shading can significantly reduce output.

5. Operating Instructions

These solar panels convert sunlight directly into electrical energy. Understanding their operational characteristics is key to effective use.

5.1 Sunlight Requirements

• The panels operate effectively only when exposed to sunlight.
• Nominal power output (2V, 160mA) is achieved under peak noon sunlight conditions.
• Output will be lower during morning, evening, or on cloudy days due to reduced sunlight intensity.
• Important: Solar panels produce minimal to no power in indoor lighting conditions. Always test and operate in direct outdoor sunlight for accurate performance assessment.

5.2 Connecting to Devices

Once connected to your circuit or device, the solar panels will begin generating power when exposed to sufficient sunlight. Ensure your device's voltage and current requirements are met by the solar panel configuration.

6. Maintenance

The AIYIMA AOSHIKE solar panels require minimal maintenance due to their durable construction.

• Cleaning: Periodically wipe the surface of the solar panel with a soft, damp cloth to remove dust, dirt, or debris. A clean surface ensures maximum light absorption and efficiency.
• Inspection: Regularly inspect the panels and their connections for any signs of physical damage or corrosion.
• Environmental Protection: While the epoxy coating offers good protection, avoid prolonged exposure to extreme temperatures or harsh chemicals that could degrade the material over time.

7. Troubleshooting

If you experience issues with your solar panels, consider the following troubleshooting steps:

• Low or No Power Output:
  • Sunlight: Ensure the panel is in direct, unobstructed sunlight. Check for shadows from buildings, trees, or other objects.
  • Cleanliness: Clean the panel surface to remove any dirt or dust accumulation.
  • Connections: Verify all solder connections are secure and free from corrosion. Check for correct polarity.
  • Testing Environment: Remember that panels will not produce significant power indoors or under weak artificial light. Test outdoors under strong sunlight.
• Panel Damage:
  • Inspect the epoxy surface for cracks or delamination.
  • Check the backplane for any visible damage to the circuit.
