Ⅰ. Solar Wall Light Won’t Turn On 

Possible Causes:  

- Dead Batteries: Rechargeable batteries degrade after 1–2 years.  

- Dirty Solar Panel: Dust, pollen, or bird droppings block sunlight.  

- Faulty Sensor: Defective dusk-to-dawn or motion sensors.  

- Water Damage: Moisture corroded battery terminals or wiring.  

Troubleshooting Steps:  

1. Test Batteries: Replace old NiMH/Li-ion batteries (check manual for specs).  

2. Clean Solar Panels: Wipe panels with a damp microfiber cloth weekly.  

3. Reset the Sensor: Cover the panel to simulate night; light should activate.  

4. Check Weather Seals: Inspect for cracks; dry components with silica gel packs if damp.  

>  Pro Tip: Use a toothbrush dipped in vinegar to scrub corroded battery contacts!

Ⅱ. Lights Stay On All Day or Won’t Shut Off  

Possible Causes:  

- Sensor Obstruction: Overgrown plants or debris triggering the motion sensor.  

- 'Always On' Mode: Accidental setting override.  

- Panel in Shade: Artificial light (e.g., porch bulbs) tricks the dusk sensor.  

Troubleshooting Steps:  

1. Trim Foliage: Clear vines/leaves within 3 feet of the sensor.  

2. Toggle Settings: Switch off 'Test' or 'Override' mode (refer to manual).  

3. Relocate Lights: Mount panels away from ambient light sources.

Ⅲ. Dim or Flickering Light Output 

Possible Causes:  

- Weak Sun Exposure: Panels need 6–8 hours of direct sunlight.  

- Low-Quality LEDs: Cheap bulbs lose brightness fast.  

- Battery Drain: Extreme cold/heat reduces battery efficiency.  

Troubleshooting Steps:  

1. Maximize Sunlight: Adjust panel angle toward the south (U.S. Northern Hemisphere).  

2. Upgrade to High-Lumen LEDs: Choose 100+ lumen bulbs for security lighting.  

3. Insulate Batteries: Wrap battery compartments in foam during winter.

Ⅳ. Short Runtime After Full Charge  

Possible Causes:  

- Aging Batteries: Holds<70% of original capacity.  

- Dirty/Low-Efficiency Panel: Grime reduces charging by 50%.  

- Overused Mode: Frequent motion activation drains power.  

Troubleshooting Steps:  

1. Replace Batteries: Opt for 2000mAh+ NiMH batteries.  

2. Deep-Clean Panels: Use 1:1 water-vinegar solution monthly.  

3. Adjust Sensitivity: Lower motion range/sensitivity in settings.
