VERY WRONG, good example of a little knowledge makes you dangerous.
The statement is OBVIOUSLY wrong, Why?
Simple: Manufactures will not sell something for less than their cost.
They buy energy wholesale, selling me the panel at retail.
If you believe the only cost to making PV is energy you have a serious lack of understanding...
I will recover in savings MORE dollars than the panel cost me over its life. Its call payback, measured in a few years, not never.
Q.E.D.
As a Fact, PV will return manufacturing energy cost in about 3 years.
2500 degrees Fahrenheit is NOT energy, its temperature. Take a 4 inch magnifying glass, focus the sun in a tiny spot, there you have 2500F. Big deal!
C02 and toxic chemicals.
one square meter of solar cells carries a burden of 75 kilograms.
You produce CO2, to say something produces 75kg of C02 is Bad then your bad.

1 meter PV in AZ will produce 140w per hour per 10 hour day. Based on link, each day it will save better than 0.5kg C02. Within 150 days its Carbon debit is well paid, with the following Years to the better.
Be-careful what you read, people with a hidden agenda spew out BS frequently, passing it off as fact when its intentionally misleading or out wright LIES. Global warming comes to mind.
BTW: Wind cost energy to produce, wind is the residual of solar energy. Each technology has its pluses and minuses. To make a blanket statement wind is better, shows ignorance. Locations with NO wind its worthless, areas with NO sun PV is worthless. Wind per KW is cheaper than PV, with that said wind is a mechanical system, no 30+ years life without lots of maintenance=$. Over its life total cost on par with PV. PV produces power for decades, clean once in a while...
Have fun,
Scott.
