A MAKE: Blog reader named Norman is interested in retro-fitting his wheel chair with solar power to get more runtime out of his chair batteries. He writes:

I have an electric wheelchair and would like to have solar power for when I ride it into town. It has two 12-volt deep cycle batteries and I am limited as to how far I can go with it. I would like to be able to keep it charged longer.

Do any MAKE readers have suggestions?
