Solar Power – Facts And Fallacies

January 20th, 2010

The recent surge in solar power popularity has led to a number of facts and fallacies on the subject.

As a very long time user of solar power, I am going to do my best to convey you some factual information, also explain why a number of the fallacies are just that – fallacies.

Let’s get one thing straight right at the beginning. There’s nothing complicated or laborious to understand about solar power. The sun shines – we tend to get to use free energy. What could be additional easy than that?

Fallacy – You’ll eliminate your electricity bill with one solar panel!
Fallacy – You’ll be able to save $one hundred, even $200 a month on your electricity bill with just one home designed solar panel!
Fallacy – Build your own wind generator for but $100 and cut $200 a month from your electricity bill!
Fallacy – Build your own solar power system for less than $200 and eliminate your electricity bill!
Fallacy – Build your own solar panel and have the electrical company PAY YOU each month!

OK, you get the idea. I have scoured the net for sensible solid solar information, and I am happy to say that it’s out there. You just have to try to to a very little digging, that’s all.

Unfortunately, what comes up first are the websites creating claims such as appear above. Now, I’m quite certain that you just, being the astute person that you are, can take these claims with a massive grain of salt. Please do not misunderstand me in any approach, I am not suggesting that you can not create a solar panel, or that you can’t build a wind generator. As a result of, given the right instruction and diligent study, you most assuredly can. All you would like is logic and a few affordable ability with normal tools and you may be able to handle the job.

The fallacies, where do we tend to begin?

If your electricity bill is $a hundred a month, and your price of electricity is twenty cents a kwh (kilowatt hour), that means that you just consume 500 kwh per month. Let’s divide that by thirty to search out your daily consumption, 16.67 kwh. Or 16,670 watt hours. That would not be a notably high consumption, so our example is kind of low.

Allow us to say that you build a solar panel which produces eighty watts. In the real world, using normal line loss figures and panel inefficiencies, and 8 hours on a daily basis of fine sun, your finish net production can be regarding 384 watt hours. Let’s spherical that up to four hundred watt hours.

Simple arithmetic shows that you may require 42 panels of this size to eliminate your electricity bill. And this more assumes that the weather can co-operate with you to try and do this one year a year. As you’ll be able to see, the claims of eliminating your electric bill with one or 2 panels fall somewhat short of reality.

And will you build a wind generator for $one hundred or less? Presumably, but there must be a reason that even a low powered business unit manufacturing 500 watts costs several times that. The very fact is that there are several items in a wind generator which would like to be optimized to provide reliable power. These include the generator portion itself, the hub and blades, plus the particular mount and tower on which the generator will reside.

The generator needs to try and made water proof, the blades which drive the generator want to be very high quality air foils, and therefore the tower needs to be able to elevate the generator no less than thirty feet on top of surrounding objects in order to take advantage of the wind. Not to say that you would like to live in an space which in fact DOES have suitable wind in the first place.

As you can see, the largest fallacy with solar power is that you cannot eliminate your electricity bill without having a substantial range of panels to supply adequate power. The added drawback of requiring an actual full system can be addressed in another article.

Your Home Power Generator Setup – Solar Home Power Or Wind Power?

January 15th, 2010

Many individuals are currently considering a home power generator system as a sensible various to cut back or maybe eliminate their power bills. Solar home power or wind power are the two obvious alternatives and each have their benefits and disadvantages. Trying into the longer term tells us that our power bills are only going to increase and it’s therefore changing into a lot of value-effective, and necessary for the conservation of our planet, for us to use clean, renewable energy to run our house power generators.

Each solar home power and wind power systems have similarities – they take an intermittent, renewable supply of energy (daylight and wind) and convert it into electricity for use either at the time of generation, or stored in battery arrays to be used later.

Wind turbines are usually cheaper to set up however in some things they can have drawbacks that make them unappealing for urban areas, where typically they’ll need large platforms or towers, to induce them high enough up that the steady prevailing winds will be used. They additionally generate a tiny quantity of noise, which might or could not be a problem for a few people. Building your own wind turbine can save you plenty of money and provide you a a lot of faster come on your investment and from then on, you are in profit year after year.

Solar home power systems are somewhat easier to set up, but commercially-put in systems will be terribly pricey and thus take a long time before come back on your investment will be realized. Again, building your own can save you a considerable quantity and can prove easier and cheaper than you may think. They are additionally situational – you actually would like a home with a southern facing space to catch sunlight for them to be optimally efficient. But, not like a wind turbine, with a solar home power setup you’ll be able to start out little and boost your home power generator system incrementally with a solar array setup.

No matter that manner you decide on for your home power generator system (wind power or solar home power), the ability assortment system is only half of the setup. You may additionally want a power converter (one thing that can take the DC power these systems generate and covert it to AC power to be used by your home) and you’ll need some way to store that power for when it will be useful.

When wondering a home power generator with solar home power as a supply, often the foremost economical method to harness the sun’s power is to heat up water for later use. A solar power water heater tends to get a ton less emphasis that photovoltaic systems because generally it’s not as easy or as convenient an addition to an existing home, but it can be done – particularly if you’ll afford to place a solar thermal assortment tank in the back yard and run the water to a hot water tank for use later. Each step where you exchange solar energy to electricity, you’re losing efficiency; each step where you are then using electricity to make heat, you’re losing efficiency again. Instead of use photoelectric cells to run your clothes dryer, you’re higher off putting your wash out on the line to dry by sunlight and breeze; likewise, using solar home power to fireplace up the hot water heater, when you’ll heat the water directly with sunlight is inefficient.

Determining how much power you wish to come up with with your home power generator system is the opposite constraint on this kind of project. 1st, you ought to see how abundant power you use; if your utility uses sensible power monitoring, you’ll try and work out how abundant power you use at specific times of the day; this may be indicative of specific appliances being started, and will conjointly tell you a lot about your actual power usage (that will help on the conservation facet of the equation). But, you are doing want to create choices based mostly on how a lot of power you utilize, what your peak usage is, and whether or not you want to go for ‘generate your own baseline load’ and use the utility company for overages, or whether you would like to use the utility company for the baseline, and use the solar power array to require the edge off during peak usage times (like using it to chop back on your air conditioning bill, for example.)

All in all, there are many choices when selecting a home power generator project and you will want to take into thought your individual scenario and needs when reaching your decision.

Benefits Of Green Energy Sources

August 25th, 2009

For a very long time, we have relied on fossil fuels. It provides heat to our homes, gas for our cars and electricity. Since we are now using it more than ever, there is a consequence. We are depleting our resources and slowly killing our planet. Fortunately, we can change our ways and then shift our attention to green energy sources.

But why green energy sources? Well because there are advantages to using them which we will never be able to get if we don’t change our ways. This is also even if some will argue that the problem with green energy is that it is sometimes difficult to generate the power we need. While that may be true, that is why there are other green energy sources available and we just to know which ones are viable given the geographic location.

The various green energy sources such as solar, wind, wave, hydropower and geothermal do not produce anything harmful which may have a negative effect on the environment. This is the exact opposite of what you get when you continue to operate a coal or nuclear power plant.

Coal you have to remember releases carbon dioxide into the air. On its own, it may not cause that much damage but there are currently 50,000 coal plants around the world and that number is expected to grow.

Nuclear plants may not release anything harmful into the air. The issue is how we dispose of the spend rods and if another nuclear accident should occur. We remember Chernobyl and Three Mile Island. We have probably learned better ways to prevent another incident from happening. Through the years, a few minor accidents have occurred and although the leak was contained, just imagine if it wasn’t?

Green energy sources may not be maintenance free but at least it does not require that much to maintain them compared to conventional means. In the end, we save money because such facilities don’t cost that much to operate.

The next advantage of using green energy sources is that we will never run out of them. For centuries, the sun’s rays have reached so has the wind which is blown from the sea. By using it, we decrease our dependence on oil which is a nonrenewable resource.

If you think about it, many of us have taken these green energy sources for granted. If we do the right thing now, future generations will not have to face the mess that we could have handled on our own years before.

In short, the power is in our hands. We have the technology and we know what to do with it. The only thing we need is to do is to put our money where our mouth is because despite the number of conferences on global warming and climate change, little has happened.

It is easy to talk about how concerned we are about the environment but you have to ask yourself when will more solar panels or wind turbines will be erected? When will the number of coal or nuclear power plants be reduced?

Green energy sources is the solution to the environmental, political and social problems of this lifetime. By spending more on these technologies, no country will have to depend on another or even a corporation for their power needs because they are self dependent and free.benefits of biomass energy

Realize How To Utilize Renewable Energy Through This Power Crisis

July 19th, 2009

Most individuals are more than a little conscious of the energy crisis that we`re facing at the moment. The idea of wind and solar power has surely been around for a long time and some people have even made use of it on a quite small scale. Nevertheless, it may just be time to begin thinking big with these renewable forms of electrcity.

Turning to Alternative Electricity Sources

Even if we carry on to use fossil fuels, there are so many downsides to this. Even as it`s expected that we still have some time left on the existing fuels, they will ultimately run out. They are a finite resource that we`ll surely use up. At the moment, we are accessing the easiest sources, but soon, more work will be needed to get to the other areas that can provide us with this type of fuel.

In addition, fossil fuels are a major factor in the present state of the environment. Whether or not you believe in global warming, there is absolutely an effect on the planet from the huge amount of pollutants being created by energy use around the planet.

There is also the financial factor to consider. Everyone was recently surprised with just how high gas prices went around the globe. While they have stabilized a little, the price of power can only go up as fossil fuels become scarcer. All this leads to the perks of wind and solar energy, both excellent renewable power sources that could well end the electricity crisis.

Why Wind AND Solar Power?

Quite plainly, it`s pretty hard to get the amount of power needed from just one type of collector. For instance, if we use only solar panels . . . what happens when we have an extended cloudy period? And likewise, if using only wind, what happens when it dies down? It`s always good to have backup systems in place and wind and solar electrcity work very well together.

At the moment, wind electrcity in the United States provides enough electricity to electrcity approximately 2 million homes. Studies have shown that it`s more than possible to provide for the electricity needs of the entire nation using just wind electrcity, which is also the most efficient and easily used alternative power source.

Solar electrcity is very useful, but it is also still fairly costly to install solar panels. While this will likely drop as the exploration and technology improve, for the moment, it`s cost prohibitive (and space prohibitive!) to use solar panels to provide the entire nation with power. Nevertheless, many areas are doing very well with solar electrcity, chiefly those in the sunnier parts of the country and with the grouping of solar and wind, you can see that there is an alternative to the oil products currently being used.

Harnessing the Energy

More and more individuals are opting to add solar panels to their homes, saving on energy bills and lowering their overall power use rate. Nevertheless, in order to really create a dent in the energy crisis, we`ll need more than just people working on the question. With cooperation, it`s possible for entire towns and even cities to run entirely on alternative electrcity sources, like those we`ve been discussing here. Visualize the impact this could have on the environment, as well as our everyday lives.

Solar and wind electrcity are the future of energy sources. Together, they provide the chance that we need to escape from the ever rising cost of fossil fuels and give us a cleaner, safer and less expensive energy.
