Can solar lights charge on a cloudy day?
Cloudy Days
Solar lights are built with receptors that receive light, store it and convert it to energy irrespective of how far away the sun is. These receptors are pretty sensitive and they can capture any ray of light no matter how small. This is what gives solar lights the ability to get charge even on cloudy days.
Can I use regular AA batteries in solar lights?
