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
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. :-)
