At work we're looking to cover most of our roof with PV to help offset the 4 electric car charging points we've just installed!
As for covering large roof areas with PV there are a number of hurdles to get over. We looked at putting about 2000 sq ft of PV on a large storage building on another site some years ago and there were issues of planning (probably not insurmountable but we were in a national park), structural considerations (the steel frame building was over 60 years old and while sound would probably need strengthening), routing cables to feed into the grid and the main one: cost! With the end of the various grants and advantageous feed-in tariffs it just wasn't worth it.
