My solar light will not turn on after three days in the sunlight. I've purchased this brand new.

Cuynde, I apologize for the less than completely satisfied feeling you are left with. Are you letting the umbrella charge in the "Off" position for several hours in direct sunlight, before turning "On" for use? Mae sure that your solar panel is connected properly and secured. You can always reach out to our customer service team via email at contact@ezreplacement.com, with any questions you may have. We would love to help!
