I heard the R4 interview the other day too. It seemed decent to be perfectly honest. Ok the company takes all the money for 25 years, but it essentially means ~40% of your electricity is free, and you don't have to worry about huge installation/maintenance bills.
Well companies are out to make money, they won't do it unless there's something in it for them - It does however make Solar more accessible for people. The only problem is the 25 year 'contract' that's tied to the roof.
