Not sure if you saw but there's a great little German startup called "We Do Solar" who produce solar panels specifically for use on Balconies. My house has a flat roof and we'll be putting solar up there in the near future but I also plan to get panels for the balcony on our second floor as it runs the full width of the house and should add quite a chunk of generation capacity (downside is it's west facing so will only really provide power from the afternoon until the sun goes down).
