Re: U.S. Shines Light on Solar Research

Decades of research have driven down the cost of going solar. In
1990, solar panels would set you back as much as 65 cents a
kilowatt-hour--nearly 4 times more than power from the grid. Today,
the price is half that, and millions of new panels have appeared on
roofs across the U.S. as a result. Yet the price is still
prohibitively high for many homeowners and businesses.

Also a matter of sunshine, roof orientation, surrounding trees... some
serious inverters, and lifetime of the rig and its components. You
are looking at minimum 10-year payback even in the perpetually snn and
cloudless American southwest, certainly considering lost interest
income in the interval.

If roof solar became hot spit, every electric company would ban
running your meter backwards. "Potential phase and reactance
incompatibility with mains, plus UNKNOWN HAZARDS. We cannot endanger
stability of the distribution grid."

Who cleans dust and dirt off the roof panels every weekend? A
zero-reflection coating to increase output 10% will not like being
either occluded or abraded.

Pfff. All the wind, flooding and hail from 'climate change'
will turn your solar panels into windmills.
