Use Solar Power For Homes In Your Home!

Friday, July 10th, 2009

So are you looking to go green and start saving your hard earned bucks (or pounds or euors etc!) on all those expensive fuel bills?

If that is the case the best way to utilize solar power for homes in when you build your own solar panel. It’s a great fun project that has so many benefits.

Now it’s impossible to give full instructions in a short article like this one, but it can get you started in the right direction.

Firstly, this project is suitable for pretty much everyone out there. You do not need specialist knowledge or any previous experience either. You just need some good guidance.

It comes from getting a really good quality instruction manual for building your solar panel and then installing it. There are currently a huge amount available in the marketplace. This will show you on a step by step basis how to do everything, including what stuff you will require to get it build.

As well as the full instructions, a really excellent guide will also include the opportunity for you to get some support and feedback from their ‘behind the scenes team’, so whenever you need a little help with the inevitable problems that will come up during the first few times that you try this process, there will be someone there for you

The actual equipment that will be needed is very easy to pick up. Much of the things can actually found around most homes and garages and everything else is available at a hardware shop. The maximum cost for everything will be around 200 bucks.

On my first project I set aside around a week to get everything built and installed. Now I have reduced that time to normally a weekend or so.

Ready to get started?

How Does Solar Energy Work and What the Costs Are

Sunday, July 5th, 2009

Defining solar energy and tracing its generating process

Solar energy can be defined as the process of transforming naturally received sunlight into machine power, chemical power and electric currents. In other words, the process of storing and using the radiant energy of the sun is termed solar energy. Different technologies and devices related to solar energy are used to convert sunlight into mechanical and chemical power, and electricity. Chief among these devices are water pumps, solar chimneys, photovoltaic cells and solar thermal equipments. In case you are thinking how exactly solar energy works, we would be addressing precisely that issue in this article.

Types of solar techniques and the huge power contained therein

In order to get a proper feel of how solar energy works, the regeneration, way of application and final usage have to be considered in detail. Solar power is widely recognized as the best renewable source of energy. When the electromagnetic waves of the sunlight strike the upper echelons of the earths atmosphere, reflection results in almost seventy per cent of these waves sent back into space. The remaining thirty per cent radiation can be effectively absorbed by the clouds as well as the landmass and water bodies on the earths surface. This solar radiation, received direct from the sun forms radiant heat, which, in turn, is tapped and converted to mechanical power, chemical power and electricity. Indeed, almost the entire amount of renewable energy source on the earths surface is comprised of solar energy. The specific individual needs, as well as the efficiency with which solar energy sources are used decide upon the way in which solar energy would work. Applications of solar power can be found in varied fields, from urban planning to architecture, and from cooking at home to powering motor vehicles.

How the solar energy would be made to work, and what tools would be used for these purposes depend on the final use to which it will be put. However, a broad classification of solar energy technologies into two separate types is easily possible. These are: 1) active solar energy techniques and 2) Passive solar energy techniques. The former method aims at direct absorption of the radiations of the sun by pumps (for conversion to mechanical power), by photovoltaic cells (for transformation into heat) or by fans (in order to generate electricity from solar power). The latter methodology, however works differently. The passive solar techniques try to obtain as much sunlight as possible. Urban planning is eased by this technique, since constructions are done in well-lit spaces which have access to plentiful sunrays. These techniques hence aim to do away with all other sources of energy, and establishing solar energy as the ultimate source. Active solar techniques, try to maximize the amount of supply of sunlight. Such detailed analysis makes it quite clear that solar energy plays a large role in our lives, and as such it should indeed be carefully examined. The fields of application of solar power are manifold as well. Solar energy is used for cooking, agriculture, architecture, planning for cities, solar lights, disinfection, desalination, and generating electricity, as well as for other purposes too. Hence, the benefits of solar power are large. However, the few cons of using solar power as an energy source need also be considered.

Advantages and disadvantages of solar energy

A thorough study of the various pros and cons of solar power is required in order to understand how it would be put to use. Solar energy is an abundant, renewable energy source, making it an extremely convenient source of power. The conventional fossil fuel energy sources often result in the release of potentially harmful greenhouse gases that often contribute to global warming. Solar energy does not involve the use of these gases. Hence, this provides an eco-friendly source of energy, and hence, is high on demand. Different vehicles and satellites can also be run on solar power. However, there are certain disadvantages of solar energy. The solar energy using units are located only at certain limited areas in the world. This is because strong and consistent sunrays are required for their effective storage and efficient use. In case adequate sunlight is not available, adequate amount of power would not be generated. Installing solar units also is rather expensive, and hence, they should be set up only in such places where they are likely to work well. The studies on the pros and cons of solar energy are still going on. It is expected that, at some point in future, most homes would have solar power converters. We would also have a cleaner, pollution-free environment, as a result.

Instead of wondering about the working mechanism of solar energy, you should consult a reference manual on the subject. Such a manual would describe how a solar power plant should be set up, at which place would such plants yield the best results and how to get hold of free batteries and other required components at a reasonable price. All the necessary safety measures as well as the details of wiring are also provided in the manual. A prior study of this manual will surely make you ready to install the solar power plant.

Solar Energy Advantages And Disadvantages Uncovered

Friday, July 3rd, 2009

No matter who you are and where you live, you can always enjoy a few things for free for as long as you live. The sun is one such thing. Since the dawn of history, the sun has been spreading its light and warmth for the entire world. Modern science has given us the measures of harnessing the tremendous energy contained in it and use it for the progress of mankind.

Think about solar energy and the first image that springs to the mind is that of those arrays of shiny photovoltaic panels adorning the rooftops and the countryside. Indeed, photovoltaic cells still remain the most popular way of generating solar power. Solar power, for one thing, is not cheap. However, even though the initial set up costs can be quite high, the long-term financial benefits of using solar power are too strong to deny.

Did you know that solar energy can actually give you the unique advantage of not only generating enough power for ourselves, but also sell off any surplus to the local utility company or the grid at a profit through what is known as the “Net-metering Scheme”. It is really a very simple process, requiring no raw materials and having no running cost. All one needs to do is connect the system to the local power grid and send back the excess power generated by him to the local company. An example will make things clearer. Say, your monthly electricity consumption is X number of units or A amount of dollars. Now, if you install a solar panel at your home that can produce 6X number of units per month that is equivalent to $5A and you draw 2X number of units from the utility for night time consumption, you are still left with 6X minus 3X or 3X number of units equivalent to $5A minus $A or $4A in your hand. Selling off surplus power seems like the only sensible and smart choice because you cannot store this power for use on rainy days. If left unused, it will usually go to waste. Therefore, the smart decision is to sell it back and make a neat stash.

One of the most important considerations when you are thinking of setting up your very own solar power system is the return on investment. Be warned that the initial investment can be fairly high by most standards, even though most states will extend financial assistance to you for the cause. This is because solar energy is eco-friendly and a clean renewable form of energy does not pollute the environment. However, you can always find out the break-even point by subtracting the value of the annual sale of electricity from the initial investment made by you. Take a look below for a typical example.

Initial investment $30,000 Annual sale value of solar electricity $ 5,000 Time to reach break-even point 6years From the 7th year onward Zero cost!

The ecological benefits of using solar energy are just too many to enumerate. First and foremost, there is the tremendous environmental edge that comes from its clean, renewable, non-fossil fuel oriented and sustainable nature. Unlike other conventional modes of energy production solar energy production does not cause air pollution simply because there is no discharge of sulfur dioxide (SO), carbon dioxide (CO), nitrogen oxide (NO) or mercury. And for the same reason, solar energy does not contribute to the contemporary problem of global warming or greenhouse effect. What’s more, with solar energy you never need to worry about smog or acid rain in the area where it is utilized. Indeed, it’s easy to see why the entire world is raving about alternative sources of energy such as solar and wind power.

Another big advantage of using solar energy comes from the fact that it is virtually free and requires very little maintenance.

What makes solar power so convenient to use is the fact they are completely self-sustained and are an independent means of energy production. This distinctiveness of operation helps installation of units anywhere under the sun, irrespective of whether other facilities are available or not. Nowadays, owing to the latest developments, it doesn’t take much to set up a fully functional solar power unit near your own house and start generating your own electricity. It is a great feeling to have your very own power plant in the backyard, supplying power to your entire household. Moreover, when it comes to portability, few things come as close as solar power. Powerful Solar energy units mounted on trailers, complete with control panel, converters, battery banks and switches are now in use in such remote areas like the South African Game Reserves where scientists are busy checking the genes of large animals like the rhinoceros or the giraffe. Independent solar energy operated units help light up their camp sites while powering their laptops for research work and other equipment and tools.

To top it all, it has already reduced the dependence on Middle Eastern countries whose oil supplies had so far been responsible for fossil fuel generated electric power. And the way people are now becoming ready to install solar power in homes and workplaces, the day is not too far away when diesel powered generators would find their place in the pages of history books.

All said and done, let us now take a look at some of the disadvantages that accompany solar energy uses. A disturbing factor is the present high cost of installation of a solar panel. Though efforts are underway to improve their affordability (there are many government schemes that extend financial help to those willing to install a solar power unit), the picture is still far from encouraging.

You must be all set to switch to solar power by now. But don’t get started all alone. What you need is a training guide – a manual, that will let you learn how to install a system. You will also need to know a few other things such as what is the best place to set up the system, where to buy the parts, how to get free batteries, safety precautions and also wiring the system. Get informed and you are ready to install solar system in your home. This the best way to ensure a quick, successful installation.

Alternative Energy – What’s Old Is New Again

Tuesday, June 30th, 2009

Alternative energy seems to be all the rage today, but a lot of people have are unsure of what it is or have different definitions. I hope this article clears things up,

alternative energy is commonly used to refer to sources of energy that are an alternative to coal, oil and natural gas. These fossil fuels have been the most common source of our energy for generations.

However our reliance on fossil fuels is relatively recent. It wasn’t that long ago that ships were powered by sales and horses move goods and people on land.

I’m sure you seen a picture of a ranch house in the American West with the windmill next to the homestead. They originally were used to pump water. Later they were actually used to generate a small amount of electric power (say, enough to power of crystal radio) in the days before rural electrification

Many people are surprised to learn that producing solar hot water heating systems was a commercially profitable business in the latter part of the 19th century and early 20th century.

I think you can see that our dependence on fossil fuels is relatively recent. Rather than something completely new, using alternative energies is a return to an older practice.

With that background, here’s my working definition of alternative energy: energy from a source other than the burning of fossil fuels (again coal, oil and its derivatives and natural gas).

We should make a distinction between alternative energy and renewable energy. People tend to assume that they’re one and the same but they aren’t. Some non-fossil fuel energy sources can be depleted.

Concern for the environment has made people aware of the impact of burning fossil fuels. While price fluctuations and occasional interruptions and supplies makes it clear that we are also running out a fossil fuel. Factors such as these have led to the increased interest in returning to alternative energy sources.

The alternative sources people most commonly think of are solar power, wind power and hydropower. However, researchers are eagerly exploring other innovative sources as well. These include things such geothermal, biomass and tidal power.

I think we can safely expect that the use of all forms of alternative energy will increase until they become the new standard.

Solar Energy: How to live off Grid

Tuesday, June 2nd, 2009

Americans spend tremendous amounts of money on electrical capacity, and moving electricity from a power plant to the home involves a lot of transmission waste, waste that you’re paying for. You’re also paying for the hidden environmental and sunk costs on power generation plants as well. Learning how to save electricity will get more of your hard earned dollars back in your bank accounts while learning how to capture and use solar energy in your home.

First, when it comes to saving energy, start with the big ticket items. For most households, the biggest draw on their electric bill comes from the refrigerator and air conditioner, followed by the water heater. All of these can be upgraded to save electricity, with energy star certified appliances. Air conditioners can be replaced with evaporative coolers in a lot of places, and there are plenty of good do it yourself kits for making solar water heaters.

Saving electricity and learning how to be more efficient is the first level. Creating solar energy on your own is the next level. Solar cells are increasing in popularity and are becoming more proficient at a much lower price. In the past, creating your own solar energy would have been a multi thousand dollar job but today it can be achieved for a few hundred. Furthermore, some governments are now offering tax credits to those that are creating their own form of power.

People are now becoming more and more aware of the idea of solar energy and the possiblity of it being used for your home. The photoelectric effect is what solar energy relys on for generating its power. This is a phenomenon in which electrons are emitted from matter after the absorption of energy from visible sun light. This all may sound a little intimidating but is actually quite fascinating and with some help along the way can be easiely achieved by the average indvidual.

The solar panels that are set up for absorbtion of the suns ultra viote rays are not only made to grab the energy and convert it to elecrity but also to store energy for use at a later time. There are also systems out there that serve two purposes in one such as a solar energy system combined with a solar thermal water heater that is a sure fire way to save electricity. There is no need to start out by getting everything all at once, you can start out with the smaller systems available and work your way up from there.

Solar systems are not cheap but having said that they are also not as costly as people tend to think. The electrical bill for most American and Canadians is one of the top three bills that weigh heavily on our wallets. Why not invest in something that can eliminate those bills all together or at least significantly reduce the costs? Getting your own solar power system does not have to be done all in one day, you can always do it step by step until you have achieved your desired reduction in costs and this reduction can be seen in as little as a year!

Obviously in this article we are just hitting the basic points of solar energy. The benefits are countless and this is just a quick overview of how easily you can be profiting from creating your own resource for energy rather than the electrical companys profits from you! Furthermore, you are getting mental satisfaction of knowing your doing something great for our planet and your children will thank you for it!
