I have a friend that has a little solar panel (12V 15W). He used it to circulate the air under his boat cover, but he sold the boat. He would like to do something with the panel. I could build him something, but I'm short of ideas.
Anyone build a neat project using a small panel?
I have a little 12v battery I would give him (7AH).
He is handy with wood and metal.

Build some type of do-nothing machine for his garden (Google whirlygig). Normally, they are wind-powered but solar could be fun.

Power a little fountain for a water feature in his garden

Have it charge an air horn to blast at deer when they eat his tulips in the spring.

Thanks,
I think I'll try the water feature out on him. :D

A 10 watt solar panel, with no help from the power grid, could keep the battery in my lawn mower in a state of float charge between uses which can range from once every 6 days to once every 3 months. In fact, I'm using less power than that to keep a car battery from sulfating while I refurbish a 2005 Ford Explorer over the course of several months.
