@Kaktus. Backyard Solar lights have a sun ray catch plate that stores the sun's energy during the day. When at night with the switch on they light up from the solar energy stored during the day on each unique solar pad. Many types …even to light a walkway at night..
See pics of them during the day.
There are many different types. Pics hanging bees with solar
Just google outdoor solar lights so many types will pop 🆙 .
I like them as they add color and movement at night.
Even the solar Tiki lights I use along the driveway at night.
They are not pricy and easy care.
One by the pond..see the square solar pad? That pad stores solar energy which light up at night.
