Comment: to blog or not to blog! that is the question

good point - however there is a definite difference between monocrystalline and polycrystalline panels and I quote:

In single crystal silicon (monocrystalline), the crystalline framework is homogenous, which can be recognized by an even external coloring.[1] In single crystal silicon, also called monocrystal, the crystal lattice of the entire sample is continuous and unbroken with no grain boundaries. Large single crystals are exceedingly rare in nature and can also be difficult to produce in the laboratory (see also recrystallisation). In contrast an amorphous structure where the atomic position is limited to short range order.

Polycrystalline and paracrystalline phases (see Polycrystal) are composed of a number of smaller crystals or crystallites. Polycrystalline silicon (or semicrystalline silicon, polysilicon, poly-Si, or simply "poly") is a material consisting of multiple small silicon crystals. Polycrystalline cells can be recognized by a visible grain, a “metal flake effect”.

So no, polycrystalline wasn't a term invented by Sharp but a proper scientific name.
