Your panels are DC. Won't work as pictured with capacitors.

Otherwise not sure what you're trying to do.

Yes, dc
6V 330mA Outdoor Solar Panel 2w

I am trying to charge two separate batter packs to operate two small motors that is represented by light bulbs. One motor,1st slower and not often.

See this link for my materials,I have double supply.

Capacitors block DC,  so you have effectively created a break in the wire where you have one.

You appear to be trying to charge 9 off 1.5v AA batteries (13.v total)  in series from a 6v solar cell, which also won't work..

With all due respect I doubt you have the knowledge to be more than dangerous around electricity, (earlier in my life , I'm 64, I witnessed a guy reach out and grab a live high tension cable, he lost all his fingers on that hand) I'd recommend that you get  basic book on electrical circuits and do some reading before offering to 'help' your grand son.

Googling, I found a basic guide at http://www.allaboutcircuits.com/textbook/direct-current/chpt-1/electric-circuits/

I haven't read it all, but it seems to start off well, so take a look, perhaps you and your grandson can read it together, and start him of the right way. Then perhaps buy a few books and components for beginner's experimenters kit.

There is a great monthly magazine for tinkerers/experimenters of all ages called 'Make'  they focus on all sorts of stuff, not just electronics, as far as electronics go they also have books and kits of parts to match the books, their basic electronic component kit looks like a good starting point. http://www.makershed.com/products/make-electronics-component-kit-1

And the accompanying book http://www.makershed.com/products/make-electronics-2ed

Best wishes and have fun. If you start him off 'right' then the world of solar electronics would make a great career.
