I don't think I want one on my roof though. My current plans are
for about 2000 watts of cells. That's 8000 watts or so of heat that
needs to be dissipated. All concentrated on 1 square inch. I would
know how ants feel...<br>

Plus of course, you still need the same size roof installation. It
is still all about<i> intercepted</i> sunlight.<br>

I come back to the thing I have been saying for years. If you
aren't making solar CHEAPER, you aren't helping. Fortunately, there
are people who are making it much cheaper. It is about 2 cents per
kWh, cheaper than power company electrons here at the moment.<br>

Thank You Kindly,<br>
