If you have a yard
and you have ever thought about lighting it at night,
then you have probably heard about led solar yard light.
They are still pretty expensive,
but their advantage is that
you don’t have to run any wiring for them.
As long as a location gets direct sunlight,
you can put a light there in about 15 seconds.
These lights are extremely interesting because led solar yard light are almost like mini-satellites.
They generate and store their own power during the day and then release it at night.
This is just like a satellite that stores solar energy while it is on the sunny side of the planet and then uses that energy when it’s on the dark side.
