I have a solar globe on my front porch. The concept is simple -- during the day it absorbs enough energy to recharge the batteries, and at night it uses the battery power to glow. It stopped glowing in early November, however. The afternoon late fall and winter sun in the far north is not strong enough to charge the batteries.
Last night I went outside, and saw that the globe was a glowing. Not brightly, but still, there had been enough solar power to get the job done.
The sun is returning.
