    Where to buy amorphous silicon solar panels ?

    Dear Forum.
    As I live far up north (Latitude 59*) I need solar panels performing during winter light conditions and want to test amorphous solar panels as they seem to give double power year over year compared to chrystalline system. Performance in summer time light conditions is of absolutely no interest as electricity is dirt cheap during summer. I can not find anyone declaring chrystalline systems during winter light conditions (200watt sun per m2) with mostly overcast and indirect sun light. I have been in contact with Linquan and Sopray but none of these companies wants to sell me amorph solar panels. My last option seem to be collecting old unisolar panels occassionally sold on ebay if I can not find a supplier. Im looking for 128-144watt panels, 5+ meters long so I can replace my roof tiles, I dont have time to waste for installing panels on top of roof, I will use the solar panels as roofing material as any solar panel has better weather resistance than any roof tile.
    All ideas appreciated. If there is real life measurement of a chrystalline system in winter conditions that would be of great interest but it seems like no one wants to talk about solar panels performance in winter light conditions.

    amorphous panels produce more voltage.sometimes, but require more square footage to produce the same wattage. And they have a limited life of sun exposure, pretty much toasted after 5 years. Maybe in the north latitudes they will last longer, but I think they are more trouble then they are worth.

      you can do the same thing with cheaper but more PV mounted more vertically or actually vertically on the walls of your home.
      Yes it will generate more in the summer than winter but if you want more in winter, install more...

        Thank you ButchDeal for the tips. That is exactly what I landed in as it seems impossible buying amorphous panels. After comparing loads of data sheets I get the impression polychrystalline solar cells may be less sensitive to angle of incoming sunlight and more recipient to diffuse light than mono. My plan is to try to buy lots of polycells but seems difficult buying in Europe, no one wants to sell me a pallet for some reason.
