I got a 5v Battery needing to be charged. The total DC output of the solar panel is about 3.5v with little amperage.
Got it hooked up to a rectifier.
Good idea? Let me know. I really don't want to blow the roof.

When I lived in a vacant lot "on the streets" of Okla. City, OK, I did what what you're trying to do. I bought auto battery trickle charge panels and the associated hardware and then tried to recharge a small 12V battery with them and use a small Radio Shack inverter with my electric shaver.
I had, at the most, 8 small panels, but I needed 30-40. That would have been too expensive, and also be visible to police helicopters that wandered overhead occasionally. (This
can sometime be considered a police state, especially in the Bible Belt.)
If you want to use them---and they were designed for that---you'll need a fortune in trickle charge panels for car batteries. But, they should work. They're simple too, except for the interconnecting hardware.
