You've asked for a module that puts out 6-9 volts @ 100 mA. A more
accurate description of a solar panel would be that it puts out 100 mA
at 6-9 volts.

Also the currewnt outputdepends somewhat on the latitude you're at. You
won't get all that current at the arctic circle.
=============================
As a rule of thumb , a starting angle (from horizontal) for setting up a
solar panel is Degrees Latitude plus 10 degrees.
My QTH is at 57 degrees north ,so I have initially set up the 2 panels
(each fitted at ground level on an adjustable hinged wooden frame) at
approx 67 degrees. , pointing due south ,which is about optimal (not having
a tracking system)
I use 2 make: Unisolar ,64Wp panels which have a non or low reflecting
surface made of a polymer ( no glass).
Rated output per panel 3.88 Amperes at 16.5 volts ; short circuit current
6.3 Amperes.
Charging 12 V Lead -Acid batteries to 14.4 V , voltage limited by a home
made shunt controller .
System includes a 150 Watts wind generator , to support system during windy
(and usually sunless) periods
Purpose : Amateur Radio station with peripherals including 12 V halogen
bulbs desk lighting.
