what kind of 12v battery is needed, would an automotive battery work or is a
special
type of cell required?

special

1. Don't pay $00 for it - they offer coupons for $49-$69 almost
monthly.

2 Plan to buy a good charge controller. The one that comes with it
will kill any battery you use in a short time.  Expect to spend maybe
$00 for the charge controller - good ones aren't cheap and cheap ones
aren't good for your battery.  You want a controller that disconnects
the solar panels from the battery when it's charged and disconnects
the load when the battery is low - you need both to prevent damage to
the battery.  If you spend $00 for a battery and it dies in a matter
of months, you'll buy the next battery wishing you had spent that $00
to buy a better controller.

3. Get a deep discharge (marine) battery that can survive the
charge-it-up/run-it-down cycle that will happen in typical use.  You
know that someone wil leave the lights on for an extended period.

You can get more power for less money if you have a friend who can
assemble a system for you, using panels from sunelec.com or the like.

Sometimes at the HF web site, frequently if you get on their email
list.

Try an auto parts store for the battery - Advance Auto Parts, PepBoys,
etc.

 Forget that huge expense and complexity. There are commercial solar shed
lights already put together for about $9
