Good Day, thank you for reaching out to Jiawei Technologies, and appreciate your interest in our products!
We are sorry to hear that the lights do not stay ON for a long period of time but however the lights will stay ON for 6-8 hours after a full charge.
Solution – Make sure the solar panel is located in direct sunlight for 5-8 hours and position the solar panel on an angle as the photo sensor to automatically turn on at dusk is located on the back of the panel to prevent the solar lights from prematurely turning on.
Kindly email us at (customerservice@jiaweitech.com) or call us at (855-760-0758) & we are looking forward to helping you rectify this issue.
