Solar Residential Energy: What is it for?

Solar energy: this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple. Everyone knows what is meant by solar energy, and that is, the energy that comes from the sun. In its most basic sense, solar energy and other solar residential equipment are nonetheless environment-friendly and not risky at all. But then you need not become one fine environmentalist first before you will be able to come across with whatever advantageous benefit solar residential energy has.

Why is the solar residential energy said to be environment-friendly? What are its general benefits? Practically speaking, when solar residential energy is used, the electrical bills tremendously go down as compared to the other type of residential energy available for all people. Why would you pay for such expensive bills when all you need to do is to employ solar residential energy?

Another major advantage of the solar residential energy is the absence of the very complicated and dangerous wiring. Solar energy lights in the garden path or any other solar energy-powered items used in your residential are ready to be installed less the wiring to be dealt with. In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned on to give off light and they need not be turned off as well when they are no longer needed.

As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes, installed, and then presto! You just have to situate them where you want them to be and never worry about them ever again.

A List of the Benefits of Solar Residential Energy

Why is the solar residential energy equally beneficial? Why is it more recommended for use? Here are some of its benefits which are truly worth the attention to be graced by anyone:

Solar residential energy is environmentally friendly. As mentioned a while ago, solar residential energy will not harm the environmental features. It is specifically clean and renewable as well. More so, it does not cause pollution just like what the rest of the traditional electrical forms do.

Solar residential energy systems need the least maintenance. They are not fuel-powered so no need to buy the refills.

Solar residential energy makes you save a lot of money. The energy that is derived from the sun can be accessed for free as you make use of solar lights, solar panels, and the likes. The federal government most of the time gives out financial incentives. You don’t get affected by the rise of the fuel rates since you are using solar residential energy.

Making use of the solar residential energy makes you entirely independent from the foreign and centralized energy sources. Power outages will not likely affect you in any manner.

Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems.

Some Common Disadvantages of the Solar Residential Energy

Of course the disadvantages will not be taken aside. Here are some of the most common disadvantages of the solar residential energy:

The employment of a solar residential energy can be expensive at first. But as time passes by, it becomes light to the pocket.

The strength of the solar residential energy will relatively depend on the location of your residence in relation with its facing to the sun. Also, the area of your residence is another point to consider. You will need large areas to install the solar panels.

The Various Solar Energy Items

There are lots of solar energy devices that you may opt to buy. Included are the solar flashlights, solar heaters, car ventilators, solar video cameras, solar radios, solar pool purifier, solar mosquito inhibitor, solar lighting, and solar fountain pumps.

What You Must Do

Back in the earlier years, solar energy powered devices were very costly that very few homeowners made use of the solar residential energy. But these days, small volumes of solar energy devices are put up for sale therefore making it affordable for all. If you don’t have enough money to fund these items you can always start small.

Solar Photovoltaic

Solar Photovoltaic: Future Energy Sources

In general, energy sources are categorized into two parts namely non-renewable energy and renewable energy. Fossil energy sources are among the first group that the bulk of activity in the world using these conventional energy.

It is no doubt that the solar photovoltaic is one source of environmentally friendly energy and is very promising in the future, because there is no pollution produced during the process of energy conversion, and more widely available source of energy in nature, namely the sun.

Fundamental issues in solar cell technology is a very low efficiency in turning solar energy into electrical energy, which to date the highest efficiency can be achieved no more than 20%, and even then in a laboratory scale.

For that in developed countries, research on solar cell is a very big concern, especially with the issue of environmental clean.

From light into electricity

In a simple solar photovoltaic consists of the p-type and n junction semiconductor material (pn junction semiconductor) that if by the sun there will be a flow of electrons, electron flow is well known as the electric current flow. While the structure of the solar cell is as shown in Figure 1.

The main part of the energy changes of sunlight to electricity is the absorber, however, each layer is also very influential on the efficiency of the solar cell. Sunlight consists of various types of electromagnetic waves in a spectrum can be seen in figure 2. Therefore here absorber is expected to absorb as much solar radiation derived from sunlight.

More detail can be explained that the sun consists of a photon-photon, if it happen to solar cell surface material (absorber), will be absorbed, reflected or simply passed (see Figure 3), and only photons with certain energy level that will liberate electrons from atomic bonds, so that electrical current flows. Energy levels is called band-gap energy which is defined as the amount of energy required to discharge electrons out of its covalent bond so that there electric current flow. To free electron from its covalent bond, photon energy (hc/v) must be slightly larger or above than the band-gap energy. If the photon energy is too much of the energy band-gap, then the extra energy will be converted in the form of heat in a solar cell. Therefore it is important to the solar cell to regulate the materials used, namely by modifying the molecular structure of the semiconductor used.

Of course, that the efficiency of solar cell can be high if the photons from sunlight to be absorbed that as much, then reduce reflection and increase recombination and conductivity of the material.

To be able to make that a photon is absorbed can be as much, then the absorber must have an energy band-gap with a wide range, making it possible to absorb sunlight so energy has a variety of these. One of the many materials being studied are known CuInSe2 is one of the direct semiconductor.

So many advantages of solar photovoltaic as described above was not a polemic and not just stop, saying there was a solar photovoltaic is true when the energy change process there is no pollution produced, but have we calculated how much pollution has been generated in the process manufacturing, small compared to the resulting efficiency. Now the challenge here is indeed how to increase efficiency, which would affect its economic value.

Wind Turbines

June 12, 2009 By: Admin Category: Wind Power

Wind Generators As Your Energy Source

Many people have started to install wind turbines, wishing to lower their bills for electricity, and in some way help make the environment safer while saving on non-renewable sources of energy. You need some knowledge before taking your various tools and purchasing your other needs for making a wind generator.

Whether you are installing a self-made or a commercial generator, you need to make sure you have the optimal location for it. You will need a place where trees and buildings are not obstructing the air flow.

If you happen to be living on a farm, obstacles probably aren’t a factor and the view of your neighbors is no concern. However when you live within the boundaries of a city, it can be a lot more difficult to install a wind generator.

The wind towers are so tall that they can be dangerous in storms and high winds, so this could impact the community. Consult not only your local authority but also your neighbors before putting one on your property. Of course you always need to consult for the county or city codes.

You have a few choices for the exact spot for your wind tower. The top of your house could be a great location or if you own enough land you can set the tower away from the house. In a small town, numerous wind generators can be installed in a common area for the whole community. So everyone can benefit from lower utility bills, and you do not have to worry about the towers getting blown over in a storm.

You could also look into other forms of renewable energy to run your house. If you have enough sun in your area, consider installing solar panels as a back up for your wind generator.

You can read more from Steven C. Jones on his blog about wind generators and renewable energy.
