Setup
Follow these steps to set up your btfarm Solar String Lights:
- Assemble the Stake: Connect the ground stake sections together and then attach the solar panel unit to the top of the stake.
- Position the Solar Panel: Choose a location that receives direct sunlight for 6-8 hours daily. Orient the solar panel to face North or South for maximum sun exposure throughout the day. The panel can be adjusted to an optimal angle.
- Initial Charge: Before first use, ensure the solar panel is charged in direct sunlight for at least 8 hours. This will maximize battery life and performance.
- Unravel the Lights: Carefully uncoil the copper wire string lights. The wire is delicate; avoid excessive pulling or sharp bends to prevent damage.

Maintenance
To ensure the longevity and optimal performance of your solar string lights, consider the following maintenance tips:
- Clean the Solar Panel: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris that may obstruct sunlight absorption. A clean panel ensures efficient charging.
- Check for Obstructions: Ensure the solar panel is not shaded by trees, buildings, or other objects throughout the day. Any obstruction will reduce charging efficiency.
- Inspect Wiring: Periodically check the copper wire for any signs of damage or breakage, especially after strong winds or heavy rain. Handle the delicate copper wire carefully during installation and adjustments.
- Winter Care: While the lights are waterproof, extreme cold or heavy snow can impact battery performance. Consider storing them indoors during prolonged periods of harsh winter weather to extend battery life.

Troubleshooting
If you encounter issues with your solar string lights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on at night. | Insufficient solar panel charge. | Ensure the solar panel is placed in direct sunlight for 6-8 hours daily. Clean the panel if dirty. |
| Lights are dim or turn off quickly. | Inadequate charging or old battery. | Relocate the solar panel to a sunnier spot. Ensure initial 8-hour charge. Battery may need replacement after extended use. |
| Lights are not working in a specific section. | Damaged copper wire or LED. | Carefully inspect the wire for breaks or kinks. Due to the delicate nature of the copper wire, individual LED repair is not typically feasible. |
| Lights remain on during the day. | Solar panel sensor is obstructed or faulty. | Ensure the solar panel is not covered or in a shaded area. If the issue persists, the sensor may be faulty. |
