Advantages and Disadvantages of SOLAR ENERGY

admin — Sun, 31 Oct 2010 03:57:01 +0000

Many of us know that solar energy is good, but few really
understand why.

Therefore, I compiled a comprehensive list of solar energy
advantages and disadvantages that will enable you to make an
educated decision whether on not Solar Power is right for YOU.
Solar Energy Advantages

1. Saves you money

After the initial investment has been recovered, the
energy from the sun is practically FREE.
The recovery/
payback period for this investment can be very short depending
on how much electricity your household uses.
Financial
incentives are available form the government that will reduce
your cost.
If your system produce more energy than you
use, your utility company can buy it from you, building up a
credit on your account! This is called net metering.
It
will save you money on your electricity bill if you have one at
all.
Solar energy does not require any fuel.
It’s not affected by the supply and demand of fuel and is
therefore not subjected to the ever-increasing price of
gasoline.
The savings are immediate and for many years
to come.
The use of solar energy indirectly reduces
health costs.

2. Environmentally friendly

Solar Energy is clean, renewable (unlike gas, oil and
coal) and sustainable, helping to protect our environment.
It does not pollute our air by releasing carbon dioxide,
nitrogen oxide, sulphur dioxide or mercury into the atmosphere
like many traditional forms of electrical generations does.
Therefore Solar Energy does not contribute to global
warming, acid rain or smog.
It actively contributes to
the decrease of harmful green house gas emissions.
It’s
generated where it is needed.
By not using any fuel,
Solar Energy does not contribute to the cost and problems of the
recovery and transportation of fuel or the storage of
radioactive waste.

3. Independent/ semi-independent

Solar Energy can be utilized to offset utility-supplied
energy consumption. It does not only reduce your electricity
bill, but will also continue to supply your home/ business with
electricity in the event of a power outage.
A Solar
Energy system can operate entirely independent, not requiring a
connection to a power or gas grid at all. Systems can therefore
be installed in remote locations (like holiday log cabins),
making it more practical and cost-effective than the supply of
utility electricity to a new site.
The use of Solar
Energy reduces our dependence on foreign and/or centralized
sources of energy, influenced by natural disasters or
international events and so contributes to a sustainable
future.
Solar Energy supports local job and wealth
creation, fuelling local economies.

4. Low/ no maintenance

Solar Energy systems are virtually maintenance free and
will last for decades.
Once installed, there are no
recurring costs.
They operate silently, have no moving
parts, do not release offensive smells and do not require you to
add any fuel.
More solar panels can easily be added in
the future when your family’s needs grow.

Solar Energy Disadvantages

The initial cost is the main disadvantage of installing
a solar energy system, largely because of the high cost of the
semi-conducting materials used in building one.
The
cost of solar energy is also high compared to non-renewable
utility-supplied electricity. As energy shortages are becoming
more common, solar energy is becoming more
price-competitive.
Solar panels require quite a large
area for installation to achieve a good level of
efficiency.
The efficiency of the system also relies on
the location of the sun, although this problem can be overcome
with the installation of certain components.
The
production of solar energy is influenced by the presence of
clouds or pollution in the air.
Similarly, no solar
energy will be produced during nighttime although a battery
backup system and/or net metering will solve this problem. See
www.dsireusa.org for details on how net metering allows you to
save electricity and money.
As far as solar powered
cars go – their slower speed might not appeal to everyone caught
up in today’s rat race.

Is Solar Energy Reliable?

admin — Sat, 23 Oct 2010 06:07:15 +0000

Solar power is becoming a way of life for many people across the globe. From isolated communities to inner city suburbs, solar energy is becoming a very popular choice to better the environment.

Solar energy has been in existence ever since life on our planet began. We have been using the strength of the sun in many different ways, past and present. The more modern technique of using solar energy has been through the use of solar panels.

Solar energy is 100% reliable, if our planet did not receive this energy, or if the energy increased or dropped significantly, then the earth would more than likely struggle to support mankind. However, some methods regarding how we use solar energy are by no means 100% reliable.

The more modern method of harnessing solar energy has been through the use of solar panels. The technology used to turn sunlight into electricity is still in its infancy. Newer and better technologies are emerging every year, and one day we can be hopeful that solar panels could easily support a large household in a reliable way.

Many people have had great success using solar panels to power their home, and this can be down to a range of factors. The main problem associated with the reliability of solar panels is the cost. Due to the more expensive panels been out of the price range of your average consumer, more and more people are opting for budget solar cells, which provide a much lower output, resulting in the disappointment of the consumer.

The people who achieve a reliable and efficient power output from solar cells either integrate these solar panels with a small home wind turbine or ground source heat pump.

The “green dream” is by no means a dream. We do have the technology available to provide 100% of a households power supply, yet cost is the bridge that places the green dream a long way away.

Solar Shed Lights

admin — Tue, 19 Oct 2010 08:10:05 +0000

Solar shed lights are a relatively new product on the market today. They consist of a small solar panel, a solar panel mount, a battery, an interior light and a wire that connects the battery to the interior light. They work by capturing the suns energy with the solar panel and turning that into 12 volt electricity. That electricity is then transferred to a battery for storage. When the light is turned on at night by its own on/off switch it runs off of the internal battery. It is all fairly simple and straight forward.

Most of the solar shed lights on the market today are easy to install, some easier than others. They are perfect for a shed, a boat house, a green house or a barn that has no electricity run to it. It is very inconvenient to try to search through a storage shed or a barn at night with a flashlight in hand. This product eliminates that at a very reasonable price. Solar shed lights can run anywhere from about $30.00 to about $100.00.

There are several things to look for in a solar shed light. First, what kind of interior light does it use? Some products use fluorescent tubes while others use Halogen or Xenon bulbs. The more popular shed lights use LED (Light Emitting Diode) lights. LEDs last a very long time and draw very little current so they will stay bright much longer. LEDs are virtually maintenance free while other types of bulbs must eventually be replaced. Replacing the bulb, while not difficult, does add to the cost of the unit.

The second thing to look for is the kind of battery it uses and if it is replaceable. Batteries will almost always wear out at some point in time and if they are difficult to replace or hard to find, again it just adds to the cost. If the solar shed light uses LED lights it is also good to know how many lights are in the fixture. Some use 6 lights while others use 10 or even 24 LED lights. The reason that may be of some importance is LEDs are quite bright but also quite small. An interior fixture that uses only 6 LEDs may not be bright enough for all applications. The more LED used the more expensive the unit but I have found that the additional cost is usually worth it.

The last thing to discover is, how long does the light operate on a full charge? Most will work for up to 2 to 4 hours at a time on a full charge. Usually an hour or two is more than sufficient time to get what ever it is you need taken care of. If you need to have a lot more time available at night then you need to consider a larger solar panel and larger capacity batteries. When you start changing out solar panels, batteries and light fixtures you get into custom configured solar lighting. Custom solar lighting is available but at a considerably higher cost.

There are new applications for solar products being invented all the time. Solar shed lights are a great example of this new technology. They are not very expensive, in the over all scheme of things and they serve a very useful purpose. Solar shed lights are easy to install on almost any surface. They also last a very long time with only minimal maintenance. It seems rare when a product comes along with a specific application that performs well, at such a modest price.

Solar Energy Negatives

admin — Fri, 15 Oct 2010 11:15:23 +0000

Change is a watch word for our planet, and changes have been made that have enhanced the Earth. Scientist are exploring the negative effects of solar energy in order to safely replace the energy sources that we presently use with this form.

Solar energy has the ability to give us cheaper if not free electricity to our homes through the use of solar panels. However, before you jump on the band wagon and go out and try to start this new power trip there are a few things you should know. There are some people who believe there are many negatives to solar power.

Many people believe that thermal solar energy has many health risks when it is used to heat water and the air in their homes. This can happen when it has not been set up properly or the manufacturer made errors when producing it.

If it is unable to store the water properly it can cause fungus and molds to grow making anyone who drinks or uses the water sick. To make sure that this does not happen you can make sure that the units used to store the water have been built from materials that are made to prevent this.

PV solar energy also as health risks that you need to be careful of. PV (photo-voltaic) panels require millions of silicon dioxide in order to be used. That number is lowered when they are exposed to heat. The materials that are released during the refining process will increase the rate of toxicity and can affect your health. This is one of the more serious negatives of solar energy that is responsible for eleven to twenty one deaths per each quadrillion joules of energy that are created.

But do not let this deter you completely. Study up on the different types of solar panels and the negatives as well as the positives. You might find that they are worth it in the end.

Solar Energy a Reliable and Practical Source

admin — Sat, 02 Oct 2010 16:45:30 +0000

These days we are experiencing a growing awareness to the fact that our energy resources, as they have been used in the last few years, are probably not going to last for long and that the energy markets are exposed to more and more rapid changes, some due to political reasons and others because of the changing climate of the planet.
Solar energy is a renewable free source of energy which is sustainable as it is not inexhaustible, unlike fossil fuels which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity. The solar electricity that is produced can supplement your entire or partial energy consumption. Using solar energy means reducing your energy bills and saving money. Also having solar PV panels adds value to your home, they are low maintenance and unobtrusive. Germany is the global leader for solar-generated electricity.
Why choose solar energy?
Australia is the luckiest country in the world. Our geography gives us the opportunity to use the most natural, sustainable and clean energy in our homes – the energy from the sun.

Solar thermal applications are the most widely used category of solar energy technology. These technologies use heat from the sun for water and space heating, ventilation, and many other applications.
Solar energy is not a new concept, it has been properly introduced to the global public many years ago and successfully implemented in different parts of the world in different ways, so we can say that solar energy is known to most people, but it is still not as popular as it should be, as a cheap replacement for other sources of energy. The energy of the sun, from its direct sun rays that are projected directly at the earth or by giant wind turbines are free fro us to use, to manipulate for our needs, and this can be done by almost anyone in any place, it just needs to technology and the know-how.

2 Quick Buying Tips for Cheaper Home Solar Panels and a Cheaper Home Wind Turbine

admin — Fri, 24 Sep 2010 03:13:51 +0000

It’s important to understand the role that technological change plays in the pricing of your home solar panels and home wind turbines. This is the third most important ingredient in budgeting for your homemade electricity solutio. Understanding your homemade electricity needs and how efficent both home solar panels and home wind turbines can be in your living environment are the other two key factors.

The Technolgy Pricing Curve

The technology price curve, when shown on a chart, looks a litle like a ski slope. On this chart the vertical axis represents price, the horizontal units sold. When the technolgy is first released it ver expensive and not many buy. However overtime more buy and as they do the price plummets until you have very large numbers being sold at a low price. This is how the technolgy pricing curve generally works.

Calculating your best time to buy.

In short the best time to buy the components to make your home solar panel and home wind turbine solution is when a component has just become yesterdays news. Many people buy the latest thing they can and this is great, but not financially efficent. Buying whatever is the standard, middle of the road component can be a good idea, however the products to watch are those that used to be the standard but have just become “old” in the last few weeks. These components should see a rapid price fall that eventually stabalizes. If you buy as soon as the price stabalises you will get the best value for money in terms of technology for your home solar panel and home wind turbine solution.

Conclusion

Buying just behind the technology curve is not for everyone. Some people want to show others that they have made a serious investment in becoming energy independant and cheaper older technolgy doesn’t fulfill this goal. If on the otherhand your goal is to build from costs effective and well tested components this brief guide will ensure you dlollar goes further.
