It is interesting that we hear so much about solar getting cheaper, but in fact, the high end only gets more expensive. That is why those people who say “I’m waiting for higher efficiency” will never see it be cost effective. The space industry will always pay much,much more for just a factor of two increase, whereas the homeowner will only ever pay the cheapest. And cheap it is!
People "waiting" often can't do math and so don't understand how cheap it really is (even 10+ years ago!), but regardless, why is there no economy of scale at the space end? Is the efficiency just going up at the same time? If so, why isn't the price just staying the same while efficiency rises?
The domestic PV is a completely different thing and now that our friends in China are pumping cells and modules by the million (billion?) the price just keeps dropping.
I'm not "waiting for efficiency", I'm "waiting until my roof can be repaired" which means "waiting for money" which should mean "not buying that IC-910H" but did not. :-)
