Solar thin film panels

What are the drawbacks of kyocera solar thin film panels.I received a quote with these and noticed a price jump to other monocrystalline set ups.
if they are more efficient is it the price that is keeping them from being commonly used?
Not sure about this brand, I have the thin film panels and am happy with them. They do take up so much more space on your roof top, so if you have the space then it is not an issue.
