How Do Solar Post Caps Work?

Solar light works by converting sunlight into a form of electricity and storing it in a battery. After the sun sets, the lights turn on and emit a nice glow to the surrounding area. Of course, with solar caps, you can’t expect these alone to completely illuminate your deck as if it were daytime, but they do give off enough light to hang out, grill, or even take your dog out at night.

Every solar post cap light is different, but in general, after a day of fun in the sun, a solar cap can stay illuminated for 10 hours.
