Today, more and more people are looking to find ways to reduce their electricity expenses. One way to accomplish this is to limit the use of any electrical appliances in the home, but most of us find this difficult to do. So what else can we do to save money on electricity bills?  One viable option is to buy solar panels so that you can generate your own electricity.

A solar panel is a device that converts light from the sun into usable electricity, the same electricity we use to power our homes, devices, appliances, and even some vehicles.  The more intense the solar light is, the more energy the solar panel can produce.

There are many advantages to using solar power.  For example, if you use your solar panel to power your electric based heating system, you won’t experience any recurring monthly expenses related to the heating of your home.  With oil or gas-based heaters, you must pay the gas or oil consumption expense monthly in order to maintain the continuous heating of your home.  Since solar power is free, you can run your electric based heating or cooling system without experiencing any extra monthly costs.  Many people like using solar power because it is a “clean energy source” and not harmful to the environment.  Some countries, the US included, actually provide tax incentives and benefits to people who buy solar panels and generate their own electricity!

Now, in buying solar panels, there are many things to consider.  One of the most important factors is to consider your electrical needs. Check or estimate the power consumption required for any of the electrical appliances in your home that you’d like to power with your solar panels. Most people use the energy from solar panels to heat their water, since a water heater or air conditioning/eating units since these all typically consume a good amount of electricity. Make a list of the wattage ratings for any electrical appliances you might want to power with the solar panel, add up all those wattage amounts and that will give you an idea about the amount of electricity you are consuming monthly when using those particular devices and appliances.  When selecting a solar panel, choose one with a slighter higher wattage rating than the amount you calculated from your list.  This ensures that the solar panel you will be buying will have enough power output for your appliances.

Considering the desired location for your panels can also affect how much you spend on the purchase.  You want your solar panels to have maximum light exposure throughout the day. The optimal placement of a solar panel involves installing the solar panels so that they directly face the sun between the hours of 9AM to 3PM, which is when the sun is at its brightest.  There are ‘add-ons’ that can be purchased to help ensure maximum light collection by the solar panel.  A solar tracker is an example of this, but it is an additional expense. Also, because the solar tracker is powered by electricity generated from the solar panel, the output of your solar panels will be lessened by its power consumption.

Another important consideration is the guaranteed service life of the solar panel. Most solar panels last for 10 to 15 years. Check your expenses to see if buying a solar panel will give you savings over such a period of time. Look at the estimated power consumption for the devices and appliances you’d like to power with the purchase of a solar panel for each month and then multiply that by 12 to get the estimated cost per year.  Now multiply that number by the guaranteed service life of the solar panel you are considering buying to see what that potential savings would be and whether or not the investment makes sense.  Remember, the solar panels only last between 10-15 years.  Many people are under the assumption that solar panels last forever.  That is simply not true.

Solar panels truly offer many benefits to both our homes and the environment, but because of their high cost, most people hesitate to buy them.  Always consider costs and benefits when buying your own solar panels.  Keep in mind the expected service life.  The goal is to enjoy the benefits of a solar panel, not suffer its cost.

Over the last 100 years, electricity has provided the means of opportunity for the greatest developments and improvements known to mankind. New technologies and inventions are constantly being developed with a dependence upon electricity. As the growth of the world’s economy increases so too does the exponential demand for electricity.

Today, electricity has become a commodity we can’t live without. In the past, fossil fuels like coal and oil have provided us with the necessary resources to produce our own electricity with the use of generators in power plants. Since the recognition that these fossil fuels were not limitless and possibly dangerous to both the environment and the inhabitants of Earth, an increased demand for new research has led to the development of safer and cleaner energy sources. One such energy source is solar power.

Solar electricity systems use indirect and direct methods of harnessing the energy of the sun. Direct methods use photovoltaics, commonly known as solar cells, made from thin slices of crystalline gallium arsenide, silicon, or other semiconductor materials to convert solar radiation into electricity. By connecting large numbers of these cells into panels, the cost of photovoltaic electricity has been reduced to 20 to 30 cents per kilowatt-hour. This technology has long been used in providing electrical energy to satellites that orbit the earth and observing satellites in the depths of space. Solar electricity systems provide a long term and sustainable energy resource because of the non-existence of mechanical parts, which is unlike the situation with power generating power plants. However, the efficiencies of these cells are relatively low and also dependent on the time of day and seasonal changes. Solar electricity systems need to convert the DC voltage into AC compatible supply in order to be used for commercial and home use.

Indirect methods utilize the concentration of solar radiation to focus the energy to heat or boil certain liquids like water, to power turbines and eventually produce electricity. One common technology is the use of a parabolic trough which consists of a linear parabolic reflector that concentrates solar energy into a receiver positioned on the focal line of the receiver. In the focal line of the receiver, tubing connected to the turbine is filled with liquid to absorb the heat generated by the concentration of the solar energy. Solar electricity systems such as this have higher efficiencies because the heat of the sun is directly utilized. Moreover, other technologies extend the efficiencies by utilizing solar power towers and solar dishes.

We have experienced the benefits of fossil fuels and realized its negative consequences. Moving the trend towards the use of sustainable and cleaner energy is a must in ensuring life on earth. Plants have harnessed the solar energy even before humans ever existed. Why can’t we replicate its ability to take the energy from the sun when we are more intelligent beings? We must stop digging the ground and oceans and start looking to the sky above. Solar electricity systems provide the means to achieve this goal.

The increase of the world’s population has brought about an increase in the growth of the world economy and an exponential increase on the demand for electricity. Today, electricity has become a commodity we can’t live without. For years, fossil fuels like coal and oil provided us with the necessary resources to produce our own electricity with the use of generators in power plants. As soon as we started to realize that not only were these fossil fuels not limitless, but that the harvesting and usage of these fuels was having damaging effects upon the Earth and our lives, research has moved towards the development of safer and cleaner energy sources.

One of the promising energy sources involves the utilization of solar radiation to harness the sun’s energy and generate electrical energy for our daily needs. Believe it or not, one measly hour of the sun’s energy hitting the Earth is equivalent to the energy consumption of the entire human race for one year. With the massive and inexhaustible energy of the sun to consider, a new trend of construction and energy conservation is rising, including the introduction of more and more solar cell homes.

Solar panel utilization has long been recognized as a means to provide an alternative energy resource and eventually free us from our dependence on fossil fuels. Large industries have invested in the development and research of this new technology, and advocacy for cleaner energy resources and cheaper commercialized solar panels production has brought this technology to households and small scale industries.
European countries like Germany, Denmark and Norway spearheaded the integration of solar panel equipment into the construction of households and structures. Solar cell homes are becoming a major trend in eco-friendly household areas in these countries. A major example is the first eco-friendly district in the world in Friedrich, Germany, where 5000 people utilize solar cell homes, specially designed to maximize sun radiation on the rooftops. The solar panels or arrays are integrated into the rooftops to harness the sun’s energy and provide eco-friendly solutions. Other major countries as well are starting to join the advocacy for solar panel utilization. Mumbai, India is one of such cities to join the latest trend.

Moreover, since the technology of solar energy utilization is emerging and promising, more and more commercial industries are starting to invest in this new technology. Because of the rapid growth of the technology, households are also starting to invest in the long term benefits of solar panels. Solar cell homes are becoming the new standard in eco-friendly building integration and construction.

Solar cell homes are just the start of the ongoing and rapid growth of this emerging and eco-friendly advocacy to protect the planet from further destruction. Although at present, solar panel installations are costly, it is a small effort considering the damage we have already inflicted upon the Earth. Moreover, considering the long term effects of alternative energy, the benefits are much higher compared to fossil fuel burning. Let us stop digging the earth for small packets fossil fuels and start looking up to the sky. As long as there is the Earth and the Sun, solar energy will be infinite. A solar cell home is just a small step in the right direction.

Every day, we all consume electric energy, whether through the use of handy MP3 players, laptops, stereo systems, televisions or massive home heating and air conditioning systems. We all need and consume power, yet most of us have never considered making “homemade electricity.”

Can you build your own electric generator? Is that even possible? Yes. But before we look into the “hows” and “whys”, let’s talk about electricity.

Electricity is a form of energy just like heat and light. Naturally occurring electric sources, however, are hard to find, and most only produce very little power. Take for example the static electricity that makes your arm hair stand up in an air-conditioned room. Fortunately, one basic law about energy is that it can be converted from one form to another. Therefore, our electric energy is just a product of converting any energy source to electricity. And because of that, we can miniaturize electric power generation.

The most common way to produce homemade electricity is through the use of a solar panel. Solar panels consist of photovoltaic cells, or in simple terms, light energy to electricity converters. Light rays from the sun activate the photovoltaic cells which produce voltage. The voltage produced from each cell is relatively small. Because of this, cells are either connected in series or parallel in order to produce the desired voltage level. Of course, solar panels have drawbacks. First is that they are very expensive to buy. Secondly, they have a low efficiency rating compared to other electric generators. So if you plan to produce your homemade electricity using solar panels, just prepare your wallet.

Another common way to produce homemade electricity is to convert wind to electricity. A wind generator is used for this method. Basically, a wind generator is a dynamo (the general name for any motor or generator) connected to a turbine that is rotated by the force of the wind. The turbine collects the wind energy, while the dynamo converts the mechanical force of the wind to electricity. As stated above, a dynamo is a general term for a motor. If a dynamo converts electrical energy to mechanical energy, it is a motor. If it converts mechanical energy to electricity, it is a generator. Compared to solar panels, wind generators provide a relatively higher efficiency. However, the wind turbine must be oriented where the wind is strongest for better electric production.

Both solar panels and wind generators will not produce electricity if there is no sunlight and wind respectively. Storing their generated energy in a battery is one solution to this problem. Care must be properly observed when using batteries, especially those with high “mAh” ratings. When short-circuited, they can produce fatal levels of current.

There are several viable options for creating your own homemade electricity. It is just a matter of a little research, a little trial-and-error, and of course a little patience before you can generate practical amounts of electric energy. Just remember to take safety precautions when dealing with electricity. You don’t want to fry your Ipod, or worse – fry yourself!
