T
oday, Solar power is the most reliable
and affordable source of electricity
implementing countrywide
development to reduce global warming
pollution, which makes country cleaner, saving
fuel costs as well. Usually small-scale Solar
photovoltaic (PV) systems, focusing on
building roofs, whereas large-scale PV systems
and Concentrating Solar Power (CSP) systems
represent the majority of Solar’s complete
electricity-generating capacity. Solar Power
has the capability to provide a significant
amount of electricity in both environmentally
as well as economically attractive.
Solar Power is increasingly
affordable
It has been observed that the prices for rooftop
PV systems have declined markedly in recent
years. The rising profit is a result of decrease
technology prices, innovative financing, and
developed networks of Solar installers and
financial partners. However, Solar consumers
are paying very little; Tax credits, rebates, and
other support in leading states could cut the
total costs of a rooftop system to under
$10,000, which will supply electricity with a
fixed rate for a longer period of time. Large-
scale PV project costs have fallen more than
household systems, 60 percent less than
residential Solar on a per-watt basis. And about
CSP system the costs are not reduced as like
small scale PV or Large scale PV, but it’s
capable of being storage of sun’s energy as
heat, so that it can utilize when there is no
sunlight.
Feasible Solar Power in Northern
Climates
PV generation requires the amount of sunlight,
which differs by less than 30% for a few
countries, still making Solar power feasible in
northern climates. Whereas in sunny locations
like Los Angeles or Phoenix a five-kilowatt
home rooftop PV system produces an around
7,000 to 8,000 kilowatt-hours per year, which
is approximately similar to the electricity use
of a typical U.S. household. These same
systems in Portland, Maine (in northern
climates) would produce 85 % of what it would
in Los Angeles, 95 % of what it would in
Miami, and 6% more than it would in Houston.
Florida and Hawaii (in the southwest) is the
best example for CSP.
