Thin flexible solar panels

Hi,
I own this glider for 14 years. First battery lasted 11 years, present
one 3 years old. To avoid overcharge turn radio on when you connect
the battery
or install a on/off switch. My battery is on charge full time when not
in the
glider. This advice was given to me by the technician who maintain the
alarm
system at work some 15 years ago. It works. At my club one other
glider has
the thin flexible panel on top of the motor door, never a problem.
Regards.
Gilles

Has anyone used these, or know anything about them?
Are there any
better units than these? I'm aware of the Strobl
units from Germany,
but they are about twice the cost per amp.

No, I don't know anything about those particular
panels, I just want to
point out that even with only 200 ma of charge, you
will need a charge
controller or you risk cooking your battery. Last
time I checked, they were
a $29.00 item. I ruined several batteries before
I learned.

Howzabout some particulars?

I've come across some thin (0.008 inches), flexible solar panels that
look like they'd be ideal for gliders. These are the PowerFilm 7.2V
100mA ($30) units, with and without adhesive on the back:

Also available at Jameco.com are Powerfilm 15.4V /100mA units that
are 10x5.9x.02" for $45.
