What
is Solar Energy
In order to know where to find solar energy you must first
know what solar energy is. Solar energy is energy from the sun.
When the sun is shining solar energy is being produced as it
sends the heat radiating to the earth. You can find solar
energy anywhere or anything that the sun can shine on. There is
a way that you can save the sunlight in order to provide heat
during the cold, which is what millions of people have done
throughout the years. It started thousands of years ago when
people where able to use a thick lens or magnifying glass on an
object that would attract the sun rays on that particular
object and could get so hot it would catch fire. This gave a
new prospective on how strong the heat from the sun really
was.
The problem with capturing the suns heat is the fact that
when it reaches the earths surface it does not go to one
particular spot. It is spread evenly over the earth where the
sunlight is able to reach. When this happens you may find it
difficult to heat something using only the sunlight. Although
the area or object may be hot if left in the sun too long it
will not reach the full heating potential of the sun's
light.
In order to use the heat efficiently to heat a room after
the sun goes down or when the sun is unable to shine because of
clouds you will need to use a source that will attract the heat
to one particular area. This source is called a solar
collector. The solar collector attracts a lot of sunlight to
one particular area allowing the sun to pass through the source
and into the space. The objects in the space absorb and hold
the heat from the sunlight and trapping it so it will not get
back out with the help of the source. Glass is a great solar
collector because it allows the sun to pass through it and into
the space but the heat from the sun can rarely escape leaving
the space under the glass to become warm or hot from the heat.
The objects in the space help to hold the heat as it comes in
so that the space will stay warmer longer. This allows the area
to be heated using solar power.
Because glass is a natural solar collector it makes it great
to put into a greenhouse or a sun room. The glass attracts the
sunlight and traps the heat inside so that they temperature in
the greenhouse or sun room remain warm even at night when the
temperature outside may be cold.
Solar energy can be found anywhere the sun shines but in
order to fill the heat you must have direct sunlight for an
extended period of time. If you just use the morning sun to
heat your home your house may not stay warm through the
night.
