Solar LED project Answered

OK so I am new to this but I have an idea I want to take the solar panels off some of those garden lights and charge a small battery pack (AAs or 9 volt) to run a bank of white LEDs to use as lights in some basement rooms. Can anyone help? I am very new to circuits and think I have a good idea but don't know how to do it.

Well, for some basic ideas you can check out my Instructable here, and maybe give it a vote! Just kidding (but seriously).

Anyway, basically what I would do is collect one PV cell for each battery pack then wire it like the picture below. Instead of the boost chip and fan, just wire in some LEDs in parallel.

Also, I'd add a diode between the PV cell and the battery pack.
