At the same time, the traditional crystaline photovoltaic manufacturing is starting to really increase because the supply of raw polysilicon is finally increasing. It isn't clear which technology will dominate. Crystaline photovoltaic is, generally speaking, somewhat more expensive, but reputed to be longer lasting and higher output. You can get anywhere between 10-25 watts per square foot of PV using crystaline. With thin film, yields are lower, maybe 5-15 watts per square foot. But thin film is a catch-all term to describe many manufacturing processes, and the potential of thin film isn't yet known. In any case, since you generally have plenty of roof space - certainly in a tropical latitude - your main concern should be installed cost per watt output. In that context efficiency isn't relevant, it only affects how much roof you cover. Good luck and let us know how you do! Marcus - thin film photovoltaic technology is just starting to take off.

In my country, The Bahamas, the masses are holding on to archaic forms of energy when we have so much sun year round. As an architect its a no brainer and I need information to push the public in that direction.

But may ask why you aren't telling a thing about xsunx ... I believe this company will also be able to become a player! thanks for your feed back Chris hello,
