Can these panels be installed on a tiled roof? How about on a felt roof or profiled sheet roof?

Yes, on all of the above mentioned roofs. If the installation surface is not smooth, as in strip metal roofs, a bottom plate is installed beneath the film panel and screwed to the roofing or to the ribs. The system is still considerably light (about 30 % of the weight of the normal system), being exceptionally quick to install and easy to reuse. The bottom plate increases the overall price of the system by less than 10 %.
