A Brief History of Solar Power in Modern times.
It seems solar power is much bigger already then most people know.
Solar power discovery led to the dawn of the computer age and space
age as we know it now. Oh yes ,solar power was around way before
computers were even thought of, the push to increase the efficiency
of early solar panels led to the invention of parts used in computers.
It seems that solar power made everything to do with computers and the
internet possible as the first major application for the solar
panels was satellite arrays. This is why investment in solar power
globally will be 10 times that of the internet amounting to over
$40 trillion US$. Read the facts below sourced from wiki
The photovoltaic effect was first experimentally demonstrated
by French physicist A. E. Becquerel. In 1839 The device was
only around 1% efficient.
Albert Einstein explained the underlying mechanism of light
instigated carrier excitation-the photoelectric effect-in 1905,
for which he received the Nobel prize in Physics in 1921.
Russell Ohl patented the modern junction semiconductor solar
cell in 1946, which was discovered while working on the
series of advances that would lead to the transistor.
From 1954 to 1960 Hoffman improved the efficiency of Solar Cells
from 2% to 14%. At first, cells were developed for toys and other
minor uses, as the cost of the electricity they produced was very
high; in relative terms, a cell that produced 1 watt of electrical
power in bright sunlight
cost about $250, comparing to $2 to $3 per watt for a coal plant.
In 1959 the United States launched Explorer 6. It featured
large solar arrays resembling wings, which became a common
feature in future satellites
by 1971 cell costs were estimated to be $100 per watt.
by 1973 Linden, New Jersey Exxon lab, Solar Power Corporation
(SPC). was producing panels at $10 per watt and selling
them at $20 per watt, a five fold decrease in prices in two years.
ARCO Solar's factory in Camarillo, California was the first
dedicated to building solar panels, and was in continual operation
from its purchase by ARCO in 1977 until 2011 when it was closed by
The widespread introduction of flat screen televisions in the
late 1990s and early 2000s led to the wide availability of large
sheets of high-quality glass, used on the front of the panels.
Solar panels are now less then $1 a watt with China leading
the way in global production by producing key materials needed
to bring solar power affordability to all. Many bankrupt solar
panel makers recently liquidated their remaining panels in stock
at a loss due to liquidation proceedings, those solar companies
in China that liquidated are no longer producing and with that
being said they no longer have stock to liquidate either so that
"glut" of supply no longer exists , so a move in investor
sentiment from supply glut to supply shortage will be the
shift from loss to profitability in the entire solar sector
production stream. From the history of solar power we can
see that China was a late participant into the production
of solar goods yet it has played the most critical role in
reducing costs which benefits all except big oil.
