The Story of Solar Panels
Solar energy has been a topic of interest for almost 150 years.
Commercial solar water heaters began to appear in the 1890s, but it’s
only in the last few decades that solar energy has become more widely
Now, with new advances in technology, solar energy through the use of
solar panels is more accessible and affordable than ever before. wasn’t
until just a few decades ago that solar panels became. Solar energy was
first conceived as a possible energy solution in the 1860s. This was
largely due to the fear that the availability of the fossil fuel coal would
decrease dramatically. Although there has been interest in solar energy
for more then a century, interest stagnated in the twentieth century
when coal and petroleum were plentiful. However, starting with the
scarcity of gasoline in the 1970s, people began to again look at the
possibilities with solar energy.
The decade that began unprecedented solar energy growth was in the 1990s. It is said that solar energy
use increased by about 20 percent each year—year after year. And that growth continues, largely to
dramatic improvements to the technology of solar panels. This improvement has made solar panels
more efficient and less expensive. One solar panel that is at the top of the market for efficiency at a
good price is the Phonosolar 250 watt AC panel. The Phonosolar 250 watt AC panel has been recognized
as an award winning solar panel; the company, Phono solar, has received high praise for their dedication
to technological innovations and system development.
Although true efficiency rating depends greatly on location, this
panel has been rated with a 17 percent efficiency rating. One of the
reasons it does so well is the technology has made it possible to
maximize the output earned in weak lighting situations; making it
possible to get more energy from less favorable conditions. It also
has a superb warranty, with a 12 year workmanship warranty and a
25 year output warranty. It also is able to withstand the harshest
environments, preventing ammonia corrosion, salt mist corrosion,
and also has a category ‘C’ fire test certification.
Thanks to innovative technology, solar panel companies have
been able to produce more efficient panels at a lower cost.
According to the Solar Energy Industry Association, the average
cost of an installed watt has decreased by 24.4 percent in 2013.
This price decrease is largely due to importing relatively
inexpensive photovoltaic panels from China. These inexpensive
panels paired with growing knowledge and technology has made
solar energy much more affordable not only for corporations, but
also for homes. With the decreasing costs and increased efficiency solar panels are becoming more
prevalent in the United States. Incentives from the government, such as the Federal Photovoltaic
Utilization Program, also help increase the number of solar energy consumers.
The increased level of efficiency is a great improvement for the industry. Now, with the same amount of
physical space necessary for the solar panels, people can get 0.3 percent more energy from the panels.
This may seem like a small improvement, but, depending on the location, this improvement can be as
much as a 20 percent increase in efficiency.
