Think Of These Benefits When Switching To Solar Energy

As the cost of conventional sources of energy continues to rise solar power is now more than ever a clean and viable source of energy for the home and for business. Billions of dollars have been spent in the United States over the past couple of decades in promoting and developing this technology. In this article we look at some of the benefits of solar energy.

It is estimated that the cost of the equipment to power a home with solar energy is 90 per cent cheaper than it was in the 1970s. And with energy bills rising rapidly it is now an increasingly attractive source of electricity.

In most cases, using solar energy to provide electricity for a home involves installing special solar photovoltaic cells in the roof of your home. It is true that the initial investment is quite expensive but this money should be recouped in savings on electricity bills over time and significant savings can be made in the long-term.

In sunnier areas solar power can meet and even exceed an average home's electricity needs at certain times of the day. Excess electricity can be stored in batteries or in certain areas it can even be sold back to electricity supply companies.

Here are some of the main benefits of solar energy:

* It's cheap - Once you make the initial investment to have solar technology installed in your home it is a free source of energy. Once it has paid for itself you can make make significant savings on your energy bills. You may even qualify for government incentives to help cover the cost. What is more it will add significantly to the value of your home. Green homes are becoming ever more popular in today's environmentally aware climate so this investment will increase your home's value and make it easier to sell if you ever move on.

* It's clean - Solar is one of the cleanest and environmentally friendly sources of energy out there. If you want to do your bit to combat climate change solar energy is the way to go.

* It's easy - Solar energy systems require very little maintenance. Once the system is installed you will have a constant source of energy and you won't have to worry about adding extra fuel, paying bills and the other chores associated with conventional sources of energy.

* It's consistent - If you use solar energy you do not have to worry about power failures. Even if your traditional source of electricity fails you will still have a back-up. In addition, if you live in a remote area that does not have easy access to centralized sources of electricity solar is an excellent alternative.

* It's neat - Even if you live in a heavily populated area installing solar panels should be no problem. Since they slot easily into the roof of your home there is no need for them to take up precious garden space. Also, while the panels themselves are costly, they are very easy and quick to install.

* It's wire free - There are a number of stand alone solar-powered appliances available today that eliminate the need for wiring. For example, you can install solar powered garden lights that you simply place in your garden that run of the sun's energy. These even have light sensors so they switch off and on automatically depending on the light.

The use of photovoltaic cells in the home can be quite expensive. However, it is not the only way to make use of the sun's energy. In colder regions homes are increasingly being designed to make the best use of the sun's energy to provide warmth. This involves sensible design of houses by using methods such as having large glass windows on the south side of the home which will help warm the home during the winter. The home will need to be protected from too much sun in the summer so trees can be used for this.

Another option is to use the sun to provide hot water from the home. This method simply involves using thin water pipes, painted black, and running them through a 'greenhouse like' box that is exposed to the sun on the outside of the home. In warmer areas this can provide hot running water throughout the home for free.

Solar energy isn't for everybody. Where you live will determine whether or not it is the right choice for you. If solar panels are not viable for you, or you are unsure if you are ready to take the plunge, you should still consider buying solar appliances when possible. There are any number of solar appliances available today including video cameras, watches, radios, fountains and much more. These all eliminate the need for batteries and/or wiring.

Cost Of Solar Panels Will Continue To Drop

The last example of this specific phenomenon was apparent was in the early 70's, when there was a crude oil trade embargo and hence, no gasoline. Substitute energies began to pop up here and there with many people jumping on the band wagon. But, gasoline soon returned in plentiful supplies and unconventional energy sources fell beneath the average consumers radar screen again. Now, in 2009, the common consumer is seeing petrol prices move higher and found a realization that global warming will be affecting finances soon. Substitute energy is back in the sentiments of the ordinary consumer and, maybe, this time for good.


Where did solar go?

Solar power for the home was a big seller during the energy crisis of the 70's. Many houses found tri-pods of solar panels on their roofs gathering what power they could. These units were found mostly in environmentally sensitive Arizona, but soon they were found across the World. Unfortunately, the solar power cell of the 70's just wasn't all that cost-effective and cost quite a bit to put in and maintain. As fossil fuel returned to the marketplace there was diminutive need for solar cells in a time of flagrant consumption. But the idea of solar energy was a good one and many trailblazers understood that it was a good idea that had yet to find its time. Solar panels never went away; they just slid back into the laboratory to await solar panel 2.0.


Solar is back and ready!

Today's solar panel is not your father's solar panel. Depending upon which type of energy you care to generate, electricity or hot water, today's solar panel has come a very long way in the form of Photovoltaics and will go further still. These cells, when combined into panel form, turn the suns rays (so-to-speak) right into power ready for use. They have also become exceedingly efficient, more environmentally sound and less expensive. Today's solar panel will sit almost anywhere and is quickly finding itself being turned into a panel the thickness of a nano particle. Solar power technology is running at extremely fast pace and driving costs down to an affordable level.


Who's using the panels?

As mentioned, it takes a change in the purse strings to see a marked change in a consumers behavior. With a technology and paradigm shift on the order of solar panels it requires a solid leap forward in panel efficiency, costs of panels , associated elements and an increase in existing costs of fuel. When these factors reach critical mass solar panels start to show up, not at the consumer level, but at the corporate and industrial level. This is simply because business moves its money where the costs-over time-are less. This is just good business. Solar panels are now, as in this past two years, become more cost effective for industry to use then to not use them over time.


Why solar panels now?

Solar panels are now being used primarily because fuel costs are just too high to ignore in favor of a new technology that is worth checking out. Companies have available empty roof space and the choice of trying something on a larger scale to see if it works versus continuing to pay higher fuel bills and environmental costs. The whole concept is extremely self serving. There is no environmental consideration involved. If the company doesn't use solar panels they have to pay fuel costs and air clean-up expenses along with variable fuel charges. They try out the solar panels and see if they work now. If they do, the company can; commit to a full solar panel program with even more efficient solar panels, significantly reduce fuel costs and almost eliminate air cleaning needs along the way. There is little environmental about it. Its just good business. After industry gets rolling, solar panel costs will drop like a stone and the consumer will jump on board because it's just good business.

The basics on Solar energy and Solar Panels

The earth receives more than enough energy from the sun in an hour to supply the world’s energy requirement for the whole year.

Unfortunately, only a tiny portion of it is harnessed and the world still relies on power plants that burn fossil fuels. The good thing, though, is that there is a constant increase in demand for solar energy; and over the years of continuous development, solar panels are much cheaper today.

During peak hours, the maximum power density that the sun can give is about 1kW per square meter. In other words, one square meter of solar panel can produce as much as 100 GWh (gigawatt hours) of electricity in one year. That is enough to power 50,000 houses.

If a solar power plant is build on 1% of the total land area of the Sahara desert, it will satisfy the world’s energy requirement.

The efficiency of solar panels depends on several factors such as pollution, clouds, temperature and atmospheric humidity.

Solar power plants are very similar to other conventional power plants – with one significant difference: The majority of power plants draw their power from fossil fuels like oil, coal and gas.

When power plants burn fossil fuels, they produce greenhouse gases that contribute to global warming. Solar power plants or solar thermal power plants (or Concentrating Solar Power plants) utilize the power of the sun’s rays to generate electricity.

The process could not be any simpler. The solar panels receive heat from the sun, which will be reflected to the receiver. The receiver converts into steam the concentrated solar energy. The steam is stored on tanks which will be used to turn the turbines and generate electricity.

The whole process does not involve any burning of any fossil fuels. Thus, solar power plants do not contribute to global warming.

The increase in the use of solar energy will bring down the demand for oil.

Today, there are more than 10,000 households with solar energy systems and the number is constantly increasing. If the demand for solar energy as well as other forms of alternative energy, the demand for oil will drop and the cost fuel will likely to follow.

Residential solar energy system can turn your electric meter backwards. Given that you are connected on a power-grid, the excess energy that your solar energy system produces will go to the electric lines to be used by other homes. As a result, any excess energy you give will be reflected on your bills. Your electric supplier will even pay for the electricity you supplied.

Residential solar energy system can save you money.

While the initial cash out for installing solar energy system at home is big, the device will pay for itself in the long run. Not only you will save money on solar energy system, you also help the environment by not contributing to carbon emissions.

Solar energy systems are reliable and can last for a very long time.

PV cells are last from 25 to 40 years. Many manufacturers of solar panels give 25 years product warranty. This is the assurance that solar panels are very dependable.

In addition, solar panels require little or no maintenance and the can be installed on most places where there is sunlight throughout the year.

What Do Solar Panels Do? How Do They Work?

What is PV solar power? You have heard the term, but you are unsure as to its meaning. You are vaguely aware that solar power has something to do with making energy from sunlight. But what is PV solar power? Is it different from other kinds of solar power?

PV solar power is different from other types. Of the two main categories of solar power, active and passive, PV solar power is active. Let's look at it.

Solar Panel

Active solar power relies on solar panels. You may picture them as flat, rectangular boxes on rooftops.

There are two main types of solar panel. From a distance, both look like rectangular boxes. Both convert sunlight into energy, but in two different ways. The terms for the two solar panel types are solar thermal collector and photovoltaic module.

1. Solar thermal collector: This solar panel takes in solar energy from the sun and uses it to heat air or water.

2. Photovoltaic module: This second type of solar panel collects solar energy and converts it to usable electricity.

Meet the PV

To answer the question, what is PV solar power, we must know what the PV is. The short answer is that PV refers to a photovoltaic module. "P" is for photo and "V" for voltaic.

The Merriam-Webster Online Dictionary defines "photovoltaic" this way.

"of, relating to, or utilizing the generation of a voltage when radiant energy falls on the boundary between dissimilar substances."

In simpler terms, "photo" refers to sunlight and "voltaic" refers to electrical energy. PV panels convert sunlight into electrical energy. Sunlight flows into the solar panel. Electrical energy flows out of the solar panel.

A PV solar panel is made up of many photovoltaic (light to volts) cells. These cells are electrically connected, and then covered with glass. The glass provides electrical insulation. It is also good protection from weather and other damaging forces.

When minimal energy is needed, such as that necessary to power a small appliance, a single PV solar panel is sufficient. When more power is needed, an "array" of solar panels is created by connecting panels to one another. If the power will not be supplied to the power grid, the solar panel(s) is connected to a charge controller, and battery. If it is intended for on-grid use, the solar panel array will be connected to an electrical inverter.

What Is PV Solar Power?

PV solar power is solar energy in the form of sunlight, which has been collected by a photovoltaic module, and converted into usable electricity.

Conventional silicon solar panels convert about 14 to 17 percent of sunlight into usable electricity. That isn't much. Late in 2006, however, a new solar cell was introduced. Solar panels that utilize the new cell can convert into electricity 22 percent of the sunlight they collect. Theoretically, the maximum that the cells of a solar panel can convert is said to be around 26 to 27 percent of incoming sunlight.

How does it work? Let's look at a very simple explanation.

Each photovoltaic cell in a PV solar panel is a semiconductor. When sunlight hits those cells, a certain part of the sunlight is absorbed by those silicon cells. The cells take in that part of the sunlight's energy. The cells then transfer the absorbed sunlight's energy to the electrons in the silicon. The electrons begin to flow, and this creates an electrical current. Metal contacts built into the top and bottom of the PV cells draw off that current and it is sent to the grid or battery. It is now usable electricity. The power grid sends it on its way, if you have used an on-grid connection. If you are using a battery, it is stored in the battery awaiting your need.

PV solar power is being used increasingly with great success, and while it is true that cloud cover can affect it, the cloudy country of Germany leads the world in successful use of solar panels.

What Is Solar Energy? And How Can It Help You?

Basically, solar power is energy that is actually harnessed from the sun. Although the sun is millions of miles away from earth, if we had the ability to harness all the energy coming from the sun, there is more than enough power there to provide all the energy we need for the entire earth. In fact, there is enough energy to provide plenty of energy for 10,000 earths. While you can use solar power for a variety of appliances and other items, you have to realize that this is different than using this power to produce heat.

There are two different principles that are used with solar power. If you want to produce hot air or hot fluids, then solar thermal principles are used. However, if you want to product electricity, photovoltaic principles are used instead. If you want to produce solar power, there are four components that are needed, including a battery, a charge controller, a solar panel, and an inverter.

It is the solar panels that actually get the radiation from the sun and use it to charge up the battery. Then, the charge regulator actually makes sure that the battery charges as it should. Of course, probably the most important pieces of equipment are going to be the solar panels and usually they output energy in watts. These panels can be wired in a variety of ways, although usually parallel or series wiring is done to either increase the amperage or the voltage.

So, are there benefits to using solar power? Yes! There are a variety of amazing benefits to using solar power. In fact, many people all over the world are already using this type of energy to supply their electricity. Some of the benefits are as follows:

- Creation of new hi-tech jobs
- Protection of the environment
- Solar power is abundant, free and renewable
- Fuel supply is diverse
- Rapid and cheap deployment

As long as the sun is hanging there in the sky, we will be able to have the energy that solar power produces. In fact, there is so much energy there, more than 10,000 times the amount of energy we need is available. You should learn as much as possible about solar power so that you will know about the great benefits offered and how your life will change for the better if you decide to go with solar power instead of using other energy sources.

CONCLUSION

Whether you have a business or a home, you’ll find that solar power can offer many advantages for both. Solar power is one of several alternative fuel energy sources that is cheap and renewable. From a business perspective this can add to the bottom line tremendously. From the home perspective using this can cut down on expenses. Since solar power is friendly to the environment, you will not have to worry about toxins or pollutants from this type of energy and you won’t have to worry about the issue of global warming either.
