Why Use Solar Energy?
Chances are, you are already using solar energy in a variety of forms. It is the primary fuel source in the creation of food, fresh water, petroleum, and wood. The question we propose is "why use solar energy to power your homes"? Is it realistic for generating useful heat and electricity?
The answer is that solar energy is reliable and free. From the early morning dawn to the late evening set, the Sun will shine each and every day. Solar energy may be the single most consistent thing there is on our planet.
Equally important we must consider the cost of fuel. Solar energy passes this test, also, because it will cost you zero. Once the equipment is in place, the Sun will keep it going each and every day! Pure and simple.
So what if your photovoltaic system is only 12% efficient, or your solar collectors absorb only 70% of the available heat? The truth is, your energy source is free! No gas stations, no utility bills, no black-outs, and no ups and downs with the economy. Once you've placed your solar energy system in service, there are no recurring fuel costs. All that could take you down would be a volcanic cloud or weeks of unstoppable rain.
The difficulties in using solar energy are with selecting the right application and the right equipment. How much does a solar energy system cost and how difficult is it to integrate? How simple or elaborate should it be? In my location, is solar energy right for me? Here we present a few straight forward answers to help your case.
If you live in locations with good amounts of sun, then your prospects for energy independence are good. In addition, you could be saving money and promoting a cleaner environment. The decision is not so difficult.
If your climate tends to be cloudy and rainy most of the time, then probably solar energy is not for you. Coastal climates and northern winters tend to be tough for this. But this does not mean you should not investigate, there may still be some opportunity.
Passive solar heating refers to making hot water and heating your home. If you are in a good solar climate, then you should consider installing these systems. They do not cost much and can be simple to integrate.
Photovoltaic (PV) solar energy refers to making electricity directly from the Sun. These special panels will take in radiation and produce steady DC electricity. Whether you could be making PV energy just depends on the circumstances of your situation.
PV panels will pay themselves off if you are an efficient user of electricity. The actual time period of payback, however, depends on your exact circumstances and your region's local rate of electricity. Some calculation may have to be performed.
They will also pay themselves off if developing a new property and avoiding the installation of electrical transmission cables routed to your home. Depending on the distance, these transmission cable costs can be significant.
If you are interested in an emergency reserve of energy, then this also is a good use for solar energy. You could charge a large bank of batteries with a small number of panels. So when you get those destructive storms and environmental disasters, just kick in the emergency reserve and ride it through.
The truth is, mankind is making good progress with solar energy technology. By engaging in independent and gridless energy systems, we can save a little money, help improve our environment, and set a good example for our kids. It is not such a bad idea to simplify our existence.
