Why It Doesn't Work? Please note that the solar panel is sensitive to light sources. To ensure optimal performance, it's important to fully charge the panel by exposing it to direct sunlight for 5-6 hours. Once charged, test the lights by covering the panel with cloth or any material that prevents light exposure during the day. If testing at night, ensure no light sources are facing the panel directly. No electricity or additional costs are required - it's a sustainable and friendly lighting solution! To activate the soft and romantic light, simply place the solar panel in a sunny area. The sun's rays will charge the battery, and the stored energy will power the LED lights at night. Our lights boast a unique design and are waterproof with an IP65 rating, making them perfect for hanging on trees or flowers in your garden. Bring magic and a variety of visual delights to your outdoor space with our solar lights!
