Doubtless you are heard lots about solar energy but always thought it was too costly, apart from minor uses in the now well-liked garden lighting systems. However, with fuel costs climbing and solar cells getting more reasonable, adding solar electricity to your house is a great, long-term solution to high energy bills.

That isn't to say they are cheap. Before rebates, it typically takes 12 or more years for a homeowner to make their investment in solar panels back. That's much longer than the average person is willing to wait. However, many states now offer rebates, so the final cost to the homeowner is much less than it use to be. The rebates vary from state to state, so it's impossible to say how much of an impact they have overall. There may also be federal incentives.

Solar panels are also steadily becoming more efficient. They produce more energy than they used to. They require relatively little maintenance, many of which you may be able to do yourself. This helps to make them very cost effective.

Solar energy is not just for making electricity. You may use it warm the water for your pool or heat your house. There are lots of options available for people that are engaging in building an energy conserving home without losing comfort.

Solar power is much, much cheaper than it used to be, as prices have fallen by 90% since the 1970s. That doesn't make it cheap – yet! – to install enough photovoltaic cells to power a house, but in some areas the incentives given to install solar cells cuts the overall cost to the homeowner about in half.

To decide if solar energy is correct for you, take some basic figures under consideration.

Check your energy usage. You have to know how enormous a system you'll need to power your house. Ensure you think about your greatest consumption levels and the chance that it'll grow somewhat.

Find out how much a photovoltaic system to meet your need will cost. The size will rely both on your energy need and on the available daylight ( solar resource ) in your neighborhood.

Find out what rebates and incentives are available to you to help decrease your costs.

Consider whether your system will be on the grid or off. On the grid has the edge that you can sell when you have an excess and buy electricity when you do not have enough, while with an off the grid system you've got a battery to store your excess.

Consider what the environmental benefits are worth to you. This is a private factor instead of a direct commercial one. It will not save your money, but realizing that you are contributing less to pollution might change how you're feeling about the cost.

Choosing to use solar energy in your house is an investment you can appreciate on many levels. Over a period of years it'll save your money as you generate green energy. It isn't inexpensive to start, but when you mix the environmental advantages with decreasing your dependence on fuel costs you can definitely appreciate the chances.

Most power plants in the United States and all over world are using fossil fuels to operate and generate electricity. Fossil fuel has been used as an energy source as long as man has learned to generate power. Fossil fuel has been around for ages and when man started using this energy sources no one though about the consequences. Fossil fuels will run out and there will be a shortage of it in near future. This shortage in fossil fuel will have its affect on our daily live and various industries. Today we see some of these affects already, fossil fuel prizes are raising and electricity is becoming more expensive. Although fossil fuels are more scares, to need for fossil fuels will still be here and will not decrease in near future. To solve this shortage of fossil fuels we will need to look for other possibilities for our energy demand.

Fortunately, alternative sources of energy are growing in fees. For example, locations with high water falls are experimenting on building a hydro-electric power plant, which turns out to be successful. Other locations with high wind speed employ a power wind mills that will convert wind energy into electricity. Also thermal and tidal powers are good choices.

Solar energy is also one of the sources of energy that's gaining in charges. Solar power has steadily been growing. Today solar power is employed generally in the USA and the benefits are common. Our solar power source, the sun, its life-span is reckoned to be another 4.5 billion years. It is fair to claim that this power source is kind of unending.

Rate of power from the Sun

The sun's radiation reaches a certain unit of area in space in the region of the Earth's orbit and is estimated to be at 1,400 watts per square meter. Out of this, photovoltaic cells (also known as solar cells) can capture 19 to 56 watts per square meter (for 15% efficiency) or an equivalent of 0.45 to 1.35 kilowatt per hour (kWh) in an annual day and night average.

Therefore, if there would be more area that'll be covered by many solar panels, these panels can produce a little more energy in the shape of electricity than what's now available from oil, gas, and other energy sources mixed ( presuming 8% solar cell potency ).

Conversion of Solar Energy

There are 2 ways of conversion of solar power. First is the direct solar energy which involves only one conversion into a serviceable form. For example :

Sunlight hits the solar cell, changing it into electricity.
Sunlight hits the absorber surface of a solar thermal collector, changing into thermal energy which can be employed to heat houses during cold season.

The 2nd is the indirect solar electricity which involves more than one conversion to reach a serviceable form. For example :

Plants use photosynthesis to transform solar energy to chemical energy, which can be burned later as fuel to generate electricity (also known as bio-fuel technology).
Hydroelectric dams and wind turbines are indirectly supplied by solar energy through its interaction with the Earth's atmosphere.

Pros and Cons of Solar Energy

Just like every other sorts of energy resources, solar power has its bits and bobs.

Pros :

Pollution-free.
Solar facilities can be run with little additional input or upkeep.
It is abounding. As discussed earlier, almost all of the inhabited areas here on Earth can be reached by daylight.

Cons:

Although it is abundant, non-tropical locations can receive little sunlight. Thus, power that will be produced in these locations is a minimum.
Only during daytime thus not available during night time.
Photovoltaic cell technologies generate direct current (DC) power which needs to be converted to alternating current (AC) power used in distribution grids.

Once massive development of the use of solar energy is materialized, expect that every household or industry in the world will now be powered by solar energy. It is not just a dream, it will be a dream come true.
