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.
Last we checked the government can’t tax it, and there is no pollution or greenhouse effect. And solar energy needs no refinement, it’s ready to go. Like a gift from heaven, perhaps nothing more perfect than pure solar energy.
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.
Selecting the right solar energy system for your home can be challenging at the start. What are the best choices for your location? What should we consider when sizing the equipment? Is solar energy really right for me? Here are a few answers to guide the way.
If you have a sunny climate with lots of solar energy, then put it to use. You will save money in the long run, and living in an environmentally friendly way. We would estimate that at least 50% of the United States could be using solar energy in some way.
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.
When it comes to making heat and hot water with solar energy – absolutely. We call this passive solar heating. These are low cost systems that can be designed directly into your business or home. The designs for passive solar heating systems can be relatively simple and inexpensive.
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.
If your household or business consumes lots of electricity then solar power is hard to justify. This is where local Utilities are good, they can kick out the juice for all the high power users and the heavy duty industries. But if you are simple in life and efficient in how you use energy, then the up-front cost of solar power can pay off over time. It could be as little as 5 years depending on the electrical rate of your local utility (i.e. California)
If you are developing a new property that has no electrical transmission cables, then solar energy systems may be right for you too. The money saved in routing transmission cable may pay for your solar energy system in itself.
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.
