Solar
power systems are becoming a more and more popular option for homes
today. It is no wonder why with all they do to save money as well as
to save the environment. The way they save the environment is by making
use of solar energy. Sunlight is an inexhaustible energy source as opposed
to many other sources of energy.
In addition to not contributing to the depletion of the planet's resources,
solar power systems do not create any harmful emissions. This is untrue
of the fossil fuels used to create city power. The use of a free and
renewable energy source is also they way in which they create money
savings for homeowners.
There are a few basic things which should be considered before the
purchase of solar power systems.
Location is one of these things. This refers in part to the geographic
location of the home- whether it is at the equator, far north of the
equator, etc. It also refers to the specific area of the home where
the solar panels will be placed.
For best results, the PV panels of solar power systems should face
solar south. Solar south is slightly different than magnetic south.
Magnetic south is determined by a compass, while solar south is determined
by the path of the sun. Though not ideal, an angle within 30 degrees
of magnetic south is also acceptable.
If a tree is shading the southern-facing parts of a home, it may be
difficult to get a solar power system to work particularly well. The
same is true of areas where the sun is always behind clouds. Some solar
power will be produced as long as there is light, but it may be very
little. Very northern locations, such as Alaska, will allow solar power
systems to produce immense amounts of energy during the summer yet very
little during the shorter days of winter.
