Absolutely, right: FSLR 200 and SPWR 70 is not out of mind. Solar energy is a future, even more than wind, hydro and thermal. Step by step efficiency will reach 23-25% while price and cost will be even cheaper than today. No one source of energy won't be able to compete. Winners are going to be those who made it first, who created an environment and captured markets. It is not difficult to calculate that all residential needs in electrical power can be covered by occupying 50% of roof tops. But besides roofs there are walls, windows, etc. We are at the very beginning of new electrical power era with new types of environmental clean electrical transportation. Take a look at losing money TSLA stock. It grows like no tomorrow. The WS predicts and understand a future. Do you believe that the WS does not understand a future of PV including Chi10? They have only the same concern as we are: who will survive and who not.
