So if it's only producing 10 % of the power striking the earth then just wait ten times longer and store the difference to be used later! But then you have to wait even longer while storing even more power because of the cut off caused by night! If day is longer than night then you may win in this race, but you can also use more than one collecter converted which will greatly speed up the entire process! Or you can just use one collector converter and increase the amount of sunlight directed to that one single unit! The point is there are ways to improve the situation and reduce the cost. Just think about it for a moment like I just did! Actually the farther North you are the shorter the payback period! Because you would use it for heating as well!
Is this what you mean?
