Better than nothing. Otherwise that sunlight is all wasted.
Better than nothing is a silly statement. If the cost to install is so hi that it never creates a positive return it is a waste of money. There is a reason that cold fusion is not in use. It is not that we cannot do it. It is that it is too expensive to do it.
At that point you are better served to just get normal windows and save that extra money for some other more cost efficient means of capturing solar power.
I dearly do hope that this technology becomes feasible though, the potential is huge.
