P.S. -- Sorry folks, I didn't see what auto correct was doing. That's
supposed to be *shingles*, not singles. . . .

Yes, I realize solar singles have been around for a while. Almost a decade
now. But until only pretty recently, they were quite expensive in
comparison to conventional PV panels.
Using coal as a cost benchmark is capricious and arbitrary. When paying
our coal-generated electricity bill, is the
The whole cost effective test is quite odd. Why is that always the
measure of whether solar is worth doing? No one ever asks this about
other things. Is having a child cost effective? How about going to a
concert? Even for other buying decisions it is rarely asked. Is a
dishwasher cost
Interesting weave developing to the term being competitive w.
coal.
First: a ridiculous benchmark ... causing artificial inertia.
Then: using coal as a benchmark being arbitrary and capricious
Then: the notion that cost effectiveness is only applied to solar.

All well and good. Of course, we need them now, and would have them by now
if this ridiculous benchmark of being competitive with coal weren't
causing artificial inertia.

Solar shingles have been available for years; Dow's Powerhouse line
since about 2005.

The first solar shingles were often more difficult to install
The devil is in the details, but I expect the Tesla house-battery will
be excellent for PV storage and micro-cogeneration. Most off-grid
houses (in my limited experience) seem to have about 10 to 20 kWh of
storage. The smallest Tesla car pack so far is 65 kWh. Assuming the
house-batteries
The dow shingles have fairly limited distribution from what can tell. They
are only selling them to roofers here in Colorado, not to solar installers
-- so despite having all of the various solar certifications, I cannot sell
them. Definitely not selling them retail to DIY folks. Needless to
