Thin Film (Amorphous PV) is larger than poly and mono crystaline so it takes more space for the same wattage. Amorphous panels work when covered with a dusting of snow. They will also work in partial shade unilke crystaline where shade will break the circuit. Of course the best installation is without any shading.
Thin Film PV is flexible and can be rolled out and glued on surfaces without puncture holes on a roof that need to be sealed that are associated with traditional PV mounting brackets. Amorphous, Thin Film PV is currently the most expensive of the three today.
Mono Crystaline PV panels work better than polycrystaline in cooler temeratures as it loses productivity in the noon heat of a very hot climate. These panels are more expensive and more efficient than polycrystaline.
Poly Crystaline PV panels are newer and cheaper than monocrystaline and less fragile.
All PV panels last 20 to 30 years and perhaps as many as 50 years.
BOSCH GLOBAL How Crystaline PVCells are made.
Electricity made from sand (silicon) and sun.
Organic Thin Film Photo Voltaic manufactured on a commercial sized label maker.
Massachusetts boasts MIT, U-Mass and Cambridge brain power and over 500 Green Energy companies including wind, solar, and flywheel within the State representing employment for 14,000 people and $250 million dollars in venture capitol.
This video also points out that utility grids who supply power with fossil fuels sources (coal and natural gas) politically block the developement of Green Energy because everyone who uses Green Energy represents a cut in their profits.

10 KW = 10,000 Watts, enough for six 1,500 watt appliances
or 176 (60 watt) light bulbs on this average sized flat roof.
Amorphous PV can be rolled out and glued onto existing metal roofing.
Solar energy should be used a long time ago. But its never too late to use it. Solar energy benefits us humans a lot.
