Solar power has been improving and become more accessible of late. In fact, solar powered items can make great gifts.
Solar powered lights for the garden are of course quite popular. So much easier than wiring up outdoor lights. They can be decorative, light up a garden path, or even be used as security lights.
Or there are solar chargers for cell phones. I like the ones for rechargeable batteries too.
These little panels may not seem like much, but I see them as a way to get people used to solar power and learning that it can work well.
