Technical Specifications:

• Type: Polycrystalline Solar Panel
  • Polycrystalline panels are made from silicon crystals that are melted together, which makes them a bit less efficient but more affordable compared to monocrystalline panels.
• Dimensions: 145 x 145 mm (5.7 x 5.7 inches)
  • This compact size makes it suitable for small-scale solar projects.
• Voltage: 6V
  • The panel generates a nominal voltage of 6 volts, suitable for various small electronic devices.
• Current: 550mA
  • It produces a current of 550 milliamperes, which is typical for small solar panels.
• Power Output: 3.3W
  • The panel provides a maximum power output of 3.3 watts under ideal conditions.

**2. Performance and Efficiency:

• Efficiency: Polycrystalline panels generally have an efficiency of around 15-18%, which is lower than monocrystalline panels but still effective for many applications.
• Temperature Coefficient: The performance of polycrystalline panels can decrease more with rising temperatures compared to monocrystalline panels.

**3. Applications:

• DIY Solar Projects: Ideal for hobbyists and DIY enthusiasts who want to build their own solar-powered devices or systems.
• Battery Charging: Can be used to charge small batteries, such as those in portable electronics or backup power systems.
• Cell Phone Chargers: Suitable for powering basic phone chargers or other small electronic devices.
• Solar Toys or Gadgets: Perfect for educational projects or solar-powered gadgets.

**4. Installation Tips:

• Mounting: Ensure the panel is securely mounted in a location with maximum sun exposure, ideally angled to capture sunlight throughout the day.
• Wiring: Connect the panel to a charge controller if you are using it to charge batteries, to avoid overcharging and to regulate the power output.
• Weather Resistance: Most panels are designed to withstand various weather conditions, but ensure they are properly sealed and protected against potential water damage.

**5. Maintenance:

• Cleaning: Regularly clean the panel surface with a soft cloth and mild detergent to remove dust, dirt, and debris that can block sunlight.
• Inspection: Periodically check for any physical damage, such as cracks or loose connections, to ensure optimal performance.

**6. Additional Considerations:

• Compatibility: Make sure the voltage and current specifications of the panel match the requirements of your device or battery.
• Power Regulation: For devices that require a stable voltage or current, consider using a voltage regulator or charge controller in conjunction with the solar panel.
