5. Operating Instructions
To ensure maximum power generation from your XTAR SP150 solar panel:
- Optimal Placement: Place the solar panel in direct sunlight, free from shadows. Adjust the kickstand throughout the day to follow the sun's path for continuous optimal exposure.
- High Conversion Efficiency: The SP150 utilizes high-performance monocrystalline cells, offering a conversion efficiency of up to 22%.
- Dual Protection and Parallel Connection: Built-in bypass diodes minimize hot-spot risks. The four PV modules are connected in parallel, ensuring output independence. If one module is partially shaded, the other modules will continue to generate power, providing up to 75% output.

6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your solar panel.
- Cleaning: Regularly clean the surface of the solar panel with a soft, damp cloth to remove dust, dirt, or debris. Avoid abrasive cleaners or harsh chemicals that could damage the ETFE coating.
- Inspection: Periodically inspect the panel for any physical damage, such as cracks, frayed cables, or loose connections.
- Storage: When not in use, fold the solar panel and store it in its kickstand case in a cool, dry place, away from direct sunlight and extreme temperatures.
- ETFE Coating: The ETFE-laminated technology provides a waterproof and durable structure, contributing to a prolonged lifespan.
7. Troubleshooting
If you encounter issues with your XTAR SP150 solar panel, refer to the following common problems and solutions:
- Low Power Output:
- Ensure the panel is in direct sunlight and not shaded by trees, buildings, or other objects.
- Adjust the panel's angle to face the sun directly.
- Clean the panel surface to remove any dirt or dust accumulation.
- Check the weather conditions; cloudy or overcast days will naturally reduce output.
- No Power Output:
- Verify all cables are securely connected between the solar panel and the power station.
- Ensure the power station is correctly configured to accept solar input.
- Inspect cables and connectors for any visible damage.
- Confirm the panel is receiving adequate sunlight.
- Connector Compatibility:
- The package includes MC4 to DC7909 (8mm) and DC7909 to DC5525 connectors. If your power station requires a different connector type, you may need to acquire a compatible adapter separately.
If the problem persists after following these steps, please contact XTAR customer support.
