Article Body:
Solar energy can be used and is used for electricity, central heating,
hot water, cooking, for producing salt and even for desalination. Solar
energy comes from the sun’s rays. Solar energy is known to be very
environmentally friendly. However, when the sun rays enter the earth’s
atmosphere it is quite dilute.


Although solar energy is known to be very environmentally friendly it
doesn’t only has advantages but also some disadvantages. Let’s discuss
some advantages and disadvantages of solar energy.


Let’s start with the main advantage of solar energy. Solar energy is
clean. To produce electricity or heat with solar energy you only need the
sun rays. There is no need to use fossil fuel in combination with sun
rays to produce electricity or heat. You just need a solar energy
collector or solar power panels in order to collect solar energy.


Solar energy is cheaper than electric heating. That is another big
advantage of solar energy. By just using solar energy you can save a lot
of money on heaters. In return you will get lower electric bills and it
also means that you don’t have to maintain heaters.


If you live in a remote area where there are no power-lines solar energy
can be the solution. There are remote areas where power companies have no
means to access your home. Solar energy is a great alternative because it
provides you with anything from heating water, electricity, and even
cooking.

Another great use of solar energy is for desalination in areas where
fresh, drinkable water is scarce. Solar energy evaporates brine and
leaves the salt crystals in the bottom of the basin. The water in turn
condenses back in another basin where it is now drinkable.
Although all of the above is very useful solar energy also has some
disadvantages. These disadvantages also need to be discussed to paint a
better overall picture.


The main disadvantage of solar energy is that it’s dilute. This means you
have to have a lot of solar collectors installed around your house. Solar
energy may be very cheap but the solar collectors are relatively
expensive and require regular maintenance in order to work properly and
efficiently. If you decide to use solar energy you need to calculate the
return on investment in order to know if the investment will be worth it.


One big disadvantage is that you need the sun rays to make use of solar
energy. If you are situated in a part of this beautiful planet where
there is not much sun light then this could be a problem. In other areas,
the sun rays are almost always covered in clouds making solar energy
collectors less efficient. You should first know if the sunshine in your
area is abundant for the most part of the year. Of course if you live in
desert areas like in Arizona or Mexico the sun produces a lot of sunshine
for the most part of the year and is ideal for solar energy collecting.

Lastly the sun only shines during the day. Therefore if you need
electricity or hot water during the night, like many of us do, it can be
a problem. You will need a backup system like the ‘old’ utility grid or
you will need to store the electricity for later use. There are battery
systems that can store solar energy for later use.

Solar energy is very clean and an alternative to conventional heating and
electrical systems. Although this is true it is also good to mention the
disadvantages of solar energy. If you are considering using solar energy
you must read this first to make a balanced decision….
