The Pros and Cons of Solar Energy
Solar energy is one of the best forms of renewable energy. But why don't we rely on it so much compared to other
countries? The answer is simply that there are pros and cons with using this form of alternative energy.
The pros of using solar energy is that the system is easy to install, there are no energy costs once it is set up,
there are no emissions like air pollutants or greenhouse gas and the sun is widely available.
A solar energy system is composed of the solar panels, the inverter, battery, charge controller, wires and support
structure. For you to produce a kilowatt of power,ÿ you will need 10 to 12 solar panels that will occupy an area of
100 square feet. If you are worried that this will cause damage to your roof, don't because it is made of light
weight materials.ÿ
When you call a contractor, it will usually take a day or two to install and cost around $10,000. Not that many
people will have cash on hand to pay for it so they can avail of a home equity loan to pay for it.
If you use a kilowatt of solar energy, you can save 170 lbs. of coal from being burned, about 300lbs of carbon
dioxide from being released into the atmosphere or 105 gallons of water that most homeowners use up every
month.
ÿ
The cons are solar cells are expensive, the rays can only be collected during the day time, the weather and where
you are located will play a factor in how much sunlight you can get and you will need a big area to collect the
power.
But some experts believe that price of these cells and its ability to collect power will improve in the future.
Right now, a kilowatt of solar energy can only produce 1,600 kilowatts of hours per year in sunny climate. That
means you will receive 5.5 hours of electricity per day. If you produce about 750 kilowatts of power, you will only
get 2.5 hours of power per day.
Solar panels come in various colors and usually have a 5 year warranty. Since manufacturers are aware that solar
energy can only work when the sun is out, they have installed batteries so you get more than 5 hours of power even
during cloudy days and nights. This is because the batteries are designed to absorb, insulate, transmit and reflect
rays coming from the sun.
But solar energy can be applied to other things and not just powering our homes. It can be used to power small
devices like calculators to bigger things like planes, satellites and cars. Since these are easy to maintain, you
don't have to worry about anything.
Now that you know the pros and cons of solar energy, the question remains, should people get into it or not? If you
look at it, the answer is definitely yes because is a renewable source of energy that does not cause any harm to
the environment. It will also greatly reduce our need for oil which has become a very hot issue especially when the
price per barrel went out to more than a hundred dollars early on this year.
People should take this seriously especially when this is not a renewable source of energy.ÿ
