I think there should be a alterante Recipe for Solar Panels, that outputs 8 Solar Panels
The Recipe should look like this:
GP GP GP
W W W
C CA C
GP= Glass Pane
W= Wafer
C=Circut
CA=Casing
Silicon Creation:
Macerting 16 Sand gives 1 Raw Silicon
1 Raw Silicon + 12 O2 Cell gives 3 Pruified Silicon in a Blast Furnace
Throw a block of Pruified Silicon in a Block Cutting Machine to get 9 Raw Wafers
Throw a Wafer together with a Helium Bottle/Cell (from Glenns Gasses) in a Blast Furnace to create 1 Wafer!
