What You Ought To Know Before Buying A Home Solar Electricity System

Monday, May 10th, 2010

The replacement of traditionally created electricity with electricity made from renewable or different resources is now a viable alternative for many people in the Western world. The main stumbling block is the preliminary expense, which is why solar electricity is still not a practical affair in most other, hotter, countries.

The truth is that installing solar panels to get your home off the grid is a lot cheaper than it was ten years ago, but it is still not cheap. Some countries have introduced incentive schemes and these are fine, as far as they go, but often they are intended for the middle classes, which is not a segment of society as big as the working class and which can afford to pay for its own energy anyway. These schemes leave the majority of the members of society stuck with the grid. The new British proposal FITS is like this.

Other countries have so-called ‘Green Options’, meaning that you can decide to pull energy from producers of electricity from users of renewable resources only, which is good as far as it goes, but the end user is still trapped in the system of being on the grid and being subject to price rises and power cuts.

If you truly want to get off the grid, do away with monthly bills and regain your freedom from the fat cat oil and electricity suppliers, you need to take a radical approach. The first step is to work out your electrical requirements.

Calculate the coldest and the hottest month and use the dearest plus 10% as your objective. The fact is that it could take you years to get off the grid, and by then appliances will be using less electricity than they do now anyway. You can also sell your surplus electricity back to the grid for real satisfaction.

The cost of the professional installation of solar energy systems can be exorbitant and take twelve years or more to recover, but if you assemble and install your own bank of solar panels, you can more than half that time frame. In fact, it is possible to decrease the cost by as much as 75%, if you are willing to assemble and install the solar panels yourself. This is a job that most capable teenagers can do, given the right plans or schemas.

The best idea, is for you to read up as much as you can on the subject, because there are several routes you can go. The main ones, using solar panels or other techniques of renewable electricity, are: remain linked up to the grid, using your own electricity first and selling back any surplus; remain hooked up, but send excess electricity to your own batteries, which could be an electric car; or you can come off the grid altogether.

The ultimate objective, in my eyes, is to supply my house with all the home-made electricity from solar panels that I need, to recharge my hybrid car’s batteries from the same source and to resell any surplus back to the electricity grid.

What a dream!

Why Choose Renewable Wind Power?

Saturday, April 17th, 2010

Electricity created from wind powered turbines is one of the most popular varieties of electricity from alternative sources and it is the fastest-growing form as well. Wind turbines are turned by the natural strength of the wind, so make electricity without ‘burning up’ any fossil fuels in the procedure. The faster (harder) the wind blows, the more electricity is generated.

Therefore, wind turbines are best placed where there are prolonged periods of high wind. The coast line is often a good place to site wind turbines. In fact many coastal towns and cities are supplementing their existing conventional electricity supply with electricity created from wind turbines.

You can still produce energy from wind, even if the wind does not blow very hard where you live, but the return will be less. It could still be sufficient, but maybe you should check out solar panels as well. For instance, it may suit your location to have a wind turbine for the winter and a couple of solar panels for the summer and winter back up.

Making a wind turbine is not rocket science, most people who are good with their hands can make a wind turbine with the help of a good set of DIY plans. The real trick is to get all the components that the plans say you will need before you start. That way, you can focus on following the plans without having to nip off every now and again to get a part.

One valid point is that you should not be worried about producing too much electricity, because many the energy companies in many countries are required to buy your surplus electricity back from you nowadays. This is not a difficult process, you just have to stay plugged into the grid and your surplus electricity will flow back into the grid altering the numbers on the meter automatically.

In this instance your meter is read monthly or quarterly as usual, but you will be given a refund rather that a bill. The more wind turbines and solar panels you set up, the bigger a reimbursement you are likely to receive. In some cases, the units of electricity that you sell back are worth up to twice the units you use from the same electricity company.

Aside from the fact that you will not be receiving an electricity bill every month or that your bill will be hugely reduced, a very important point is that you will be one of the very, very few people who is not badly affecting our planet. You will not be so accountable for the greenhouse gases that are created by manufacturing conventional electricity.

You have nothing to lose by learning more about creating your own electricity, coming off the grid and doing your bit for the environment. The very least that can happen is that you read the information and become wiser on the subject and you may not implement you knowledge that you have learned. This would be a real pity, but not a big financial loss.

Converting Your Home Into A Solar Home

Thursday, April 15th, 2010

When it comes to converting your home into a solar home, there are several alternatives, because not all homes have the same problems, the same requirements or the same potential sustainable power sources. Therefore, if you are going to try a total conversion or even get off the grid completely, you will either need to do some do research or call in an expert to make a survey for you.

If you call in an expert, try to get an independent one, so that you can work out the costs of fulfilling your energy requirements yourself. You will have to pay for such a report, of course, but you could carry out a report yourself with a bit of work on your behalf. In order to create a solar home, you may find the rest of this piece interesting.

There are basically two kinds of solar design: passive and active solar energy. Passive solar energy can be used to supply heating, cooling and natural light for your home. Active solar energy is used for powering home appliances, tools and lighting. It is the ideal blend of these two kinds of solar energy that you will try to accomplish, if you are attempting to convert your home into a solar home.

You can make use of passive solar energy methods in many ways, although they are more easily incorporated in during the actual construction phase of a new home. The largest area of glass should face south or be within 30 degrees of due south. This will catch the maximum amount of heat. This heat can then be circulated around the house by stone floors and stone walls.

The central heating ducting and furnace fan can be used to assist, if necessary. If the house becomes too hot in the summer, awnings or even solar panels could be dropped down in order to put the windows in shade. When thinking of passive solar energy, you should try to think of ways of providing warmth and coolness without using electricity. For example, a skylight at the top of the stairs will allow the warmest air in the house to escape, since hot air rises. This will cause cooler air to be sucked into the house at lower levels.

The other aspect of a solar house is the creation of electricity by the deployment of solar panels grouped into solar arrays. Solar panels make use of photovoltaic cells to convert light into energy. This energy can then be used to power everyday electrical appliances of all kinds or some or all of it can be stored in batteries for later use. Conversion from AC (alternating current) to DC (direct current) and back again, if needed, is a straightforward affair.

Solar energy can also be used to heat water for the pool or for the home. The most common type of system uses pipes filled with a kind of anti-freeze to collect the sun’s heat and pass it on to tanks of water via a heat exchanger.

A solar home uses energy efficiency to reduce the necessity for heating, cooling and electricity. The use of higher grade insulation, more energy efficient windows, kitchen appliances and lighting than those used in traditional homes, will save you a lot of money and energy. As you can see, some of these alterations, particularly the passive ones are structural, so hard to implement in many homes, but there is always something you can do to cut your energy bills and slowly convert your home into a solar home.

Why Not Construct A Wind Turbine For Free Electricity?

Monday, April 5th, 2010

Have you ever thought about building your own wind turbine? It is not as simple as building your own solar panels but it is not hard either. Making your wind turbine look attractive is a bigger problem than making electricity from it. The first thing you have to do is invest in a set of plans to make a wind turbine and then set about buying all the components.

Assembling the components is easy. The bits and pieces can be picked up cheap from vehicle scrap yards and your local DIY store. Just imagine being even only 50% self-sufficient in electricity? Add in a few solar panels or a second wind turbine and you could soon be off the grid altogether.

Everyone knows about the continually increasing cost of electricity and that it would be a good idea to generate energy from the wind and the sun just for the cost of the generators – the wind turbines and the solar panels – so you may be asking yourself why it is not a good idea to just go out and buy what you need from a professional installer.

Well, the answer to that is expense. Professionally installed wind turbines can cost tens of thousands of dollars and it can take 20 years to recover the cost. On the other hand you can make your own for between $200 and $500.

If the turbine saves you $200 a month then it is obvious that you will have regained your costs within three months maximum, if you make the turbine yourself. This is a very good incentive as with a little regular maintenance it will last you 15-25 years. Let’s just say 15 years or 180 months at at least $200 per month. That is $36,000 or an 7,200% return on investment.

Wind generated electrical power is very green as it takes practically no fossil fuels to make it. I say practically none, because it may need a little engine oil to keep the blades turning smoothly. And that is it. You may have to replace a bearing from time to time, but that is the extent of your maintenance routine. It is not harsh. You will also have to put some water in the batteries from time to time as well, unless you buy the sealed units, which you cannot fill up.

It really is not so difficult to assemble a wind generator. The average DIYer can complete this venture with everyday tools. There are detailed instructions and plans available on the Internet or at DIY stores to manufacture a wind generator in your workshop or home.

So why not start to make yourself a wind turbine today? Fix it on a roof or a pole and begin generating your very own free electricity. You could be off that grid faster than you know it and you will be doing more than your bit to help the planet too.

If you want to read more about home-made wind turbines and solar panels, there is plenty of advice on the Internet.

Come Off The Grid By Creating Your Own Solar Panels

Tuesday, March 30th, 2010

How would you like to come off the electricity grid? What a dream, eh? Sadly, it will remain a dream for the majority of people because the cost of having solar panels installed professionally hardly warrants the cost. Many experts calculate that it can take well over 10 years to recoup the cost of the professional installation of solar panels. This is way beyond the horizons of most home owners, who would expect a break-even point of three to five years. This is not going to happen in the near future, even with the rapidly rising cost of electricity.

However, there is an alternative. Everybody knows that the labour element in any professional job is equivalent to or even exceeds the cost of the materials in that job, so you could save half the cost just by installing the solar panels yourself. How about saving another 50% or more on the cost of the solar panels by assembling them yourself too?

Now we are getting into the realm where the cost of a viable solar power system to replace state electricity is credible. It could even pay for itself in a couple of years by reducing your dependence on the grid or even enabling you to come off it altogether. Did you know that the grid will purchase your surplus electricity from you as well?

This may sound like fantasy, but it is not that hard if you have plans or and a solar panel kit. In fact, the parts necessary to make your own solar panels are quite common these days and you will be able to pick them up either at your local hardware store or at a hobbyists like Radio Shack. If you reckon that that is too time-consuming, you could just purchase a kit. These kits are so straightforward that any teenager should be able to assemble one.

Later on, after assembling a kit or two, you may have the confidence to buy the bits separately, which will save you even more money. One of these kits would be enough to power a few tools in your shed or the lights in your garage or a pump on the pond or pool. If you grouped a few of them together, you could begin to reduce your home’s reliance on the grid just by harnessing the energy of the sun. Wouldn’t that be great?

Solar panels have been about for a long time and so people remember when they needed strong sun light to be of any use, but public awareness has not kept up with the pace of technological development. Solar panels are much more sensitive now and they can produce electricity from light using powerful photo voltaic cells (PV’s) – they do not require blazing sunshine to work any more.

So, if you want to go down the road to independence from the electricity grid, the first thing you have to do is find a set of solar panel diagrams or plans or a kit. You may be able to obtain these from your hobbyist store too or you can get them from a website that specializes in sustainable or alternative energy sources.

Once you have all your parts and your plans, it will only take you a couple of free hours to assemble your solar panel and have it working for you. The next one will take even less time as you become accustomed to it
