Solar Energy: General Advice

It is the year 2010 and we all are somewhat aware of the merits this natural and cheapest form of energy known as the Solar Energy brings. Decades back most of us did not know as much about solar energy as we do now. We are educated enough to know that the sources of energy on Earth, most of which come from fossil fuels, are in the process of depletion. Research has suggested that the only way to maintain survival is by making optimal use of energy emitted from the sun. Solar energy or solar power as we call it is the cleanest and efficient form of energy.

Solar power is extracted from the Sun and once there is plenty of it, it can be transmuted to other types and forms of energy such as thermal or electrical energies. It is presumed that solar power is one of the most authentic and dependable form of energy which can supersede other sources of energy. It is because of this feature that solar energy is considered as power generator for the future.

The existing sources of energy are not only causing environmental and health problems such as pollution and global warming but are also unable to meet the growing demand of energy. The increase in demand is due to increase in population, which connotes that more power is required on domestic and commercial level.

Most of us wonder as to how solar power works. Well, the mechanism is simple; light coming from Sun is captured by photovoltaic cells which transform it into useful form of energy. Photovoltaic or solar cells are made of silicon, which is a popular semi-conductor. Strategically, these cells when connected in an organized pattern result in a solar panel. Silicon cells serve the function of absorbing sunlight as it is emitted.

When solar panels succeed in capturing ample amount of sunlight, the electrons of silicon are set free to move towards the other side of the panel in search of positive charges. It is in this phase of electron movement that electric current is produced. The panel is connected to a battery in which this current/voltage is kept for storage purpose. The battery can be then connected to the electrical appliance you want to operate.

Solar energy is a never-ending form of energy because it is produced from sunlight which will always be available in profusion.

A Bright Future For Solar Energy: An Alternative Energy Source

I was first introduced to solar energy in the movie, Race the Sun with James Belushi and Halley Berry in the lead. It was a story about low- income and under achieving Hawaiian students encouraged by their teacher to join the Solar Car race. In the movie, a car shaped like a cockroach and covered with solar panels used the sun’s rays as an alternative energy source to run the car.

Solar energy is the light and the heat from the sun. Solar energy is free and its supplies are unlimited. There are n air and water pollution caused about by using solar energy. But there is still some impacts on the environment although indirect.

Photovoltaic cells used to convert sunlight into electricity uses silicon and also produce some waste materials. There are also large solar thermal farms and these farms can also be harmful to the environment and desert ecosystems if not properly managed.

Solar energy can be used on different aspects. Solar energy can be used in agriculture. Greenhouses (which is entirely different from greenhouse gas) convert solar light to heat to be maximized in enhancing the growth of plants and crops. Greenhouses has been around since the Roman times and modern greenhouses were built in Europe in 16th century. Greenhouses are still an important part of horticulture nowadays,

Daylight systems are also being used to maximize the energy released by the sun. It is used to provide interior illumination replacing the artificial lighting. Daylight systems include sawtooth roofs, light shelf, skylights, and light tube. Daylight systems when they are properly implemented can reduce lighting-related energy consumption by 25 percent.

Solar energy can also be developed into solar thermal technologies which can be used for water heating, space heating, space cooling and process heat generation. Solar energy can also be used to distil water and make saline or brackish water potable or drinkable.

The solar water disinfection or SODIS involves exposing water-filled plastic polyethylene terephthalate or PET bottles. This process takes a long time, since the exposure time varies on the weather conditions. It requires a minimum of six hours to two days during days with overcast conditions. Currently, there are two million people in developing centuries use SODIS for their daily drinking water needs.

Also sunlight can be converted into electricity using photovoltaics or PV. PV has been mainly used to power small and medium-sized things like a calculator powered by a single solar cell. There are homes powered by photovoltaics. Using solar energy for water and space heating is the most widely use application of solar energy. While ventilation and solar air heating is also growing in popularity.

There are three main ways in using solar energy. The main way of using and converting solar energy is by using the solar cells. Solar cells convert light directly into electricity. Solar cells are also called photovoltaic or photoelectric cells.

Meanwhile, solar furnaces use a huge array of mirrors to concentrate on the Sun’s energy into a small space and produced very high temperatures. Solar furnaces are also called “solar cookers”. A solar cooker can be used in hot countries to cook food.

With all the benefits if using solar energy, there is still a downside for this alternative energy source. It does not work during night time. The cost of setting up solar stations is expensive, but the benefit of using solar energy when accumulated is so much more.

Solar-Powered External Lamps

Mankind desires light. We humans are reliant on light unlike some other species. Our whole world existed only in the day time for millions of years. We woke up with the sunlight and went to bed when the sun went down. Afterward, we learned to produce our own light, but we were not totally successful at it until we commenced using electricity to produce light.

This has worked well for almost a hundred years, but now we know that the main fuel used to produce our electricity, namely oil, is becoming too difficult to obtain and more and more wars are being fought to guarantee the West’s supply of oil.

Not only that, but greater and greater risks are being taken by oil companies, which has lead to more and more disasters like that of the deep sea rig off Louisiana in the USA.

Consequently, the time has arrived, some even say that it is long overdue, that we rely on a different source of power and less on oil. The simplest and least risky way to produce electricity at the moment seems to be solar power. The technology has been with us for decades, but it was not viable for households to use it because it was too expensive, but that is no longer true.

The ability to use solar power to produce electricity for our lighting and indeed all our requirements is there, already at hand. The only problem is that there are many oil baron billionaires who do not see this advancement as being in their interest. And they are right, in a way, it is not in their selfish interest to decrease our dependence on oil, but it is in the planet’s and its population’s interest. That is mankind’s predicament at this moment.

Solar panels can be utilized to make electricity for immediate use either inside or outside the home and the surplus generated can either be stored in batteries or fed back into the electric grid for which you will be remunerated (and remunerated at a very high rate, in some countries).

If you do not want to come off the grid just quite yet, you could still use solar panels to power some of your external lights. In fact, there is a wide choice of outdoor lighting that makes its own power.

These external lights use mini solar panels, which the manufacturer has built in to the casing of the light to create power from the sunlight during daylight hours and then stores it in internal batteries to be used later.

These lamps also have a capacity to run the light on battery power from dusk until dawn. The solar unit determines whether to charge the batteries or supply light by the intensity of the ambient light. This solar power set up is perfect for exterior security lighting and accent lighting in the garden. They are just the thing for lighting up the fish pond or the drive too.

Solar powered external lighting has come a long way and it is well worth you finding out more, if you would like to reduce your dependency on electricity produced by oil from the grid.

Owen Jones, the author of this article writes on quite a few topics, but is at present concerned with outdoor accent lighting. If you would like to know more or check out some great offers, please go to our website at Outdoor Wall Lamps.

Converting Your Home Into A Solar Home

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 entirely, you will either need to do some research or call in an expert to make a report for you.

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

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

You can use passive solar energy techniques in many ways, although they are more easily built 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 distributed 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 shadow. When thinking of passive solar energy, you should try to think of means of supplying warmth and coolness without using electricity. For instance, a skylight at the top of the stairs will permit the warmest air in the house to escape, since hot air rises. This will result in 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 warm up water for the pool or for the home. The most common type of system uses pipes filled with a type of anti-freeze to collect the sun’s heat and pass it on to tanks of water by means of a heat exchanger.

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

Is Solar Power Right For You?

Until approximately a hundred years ago in the West, people only had recourse to renewable energy for heat and light for their homes. They burnt wood and sometimes coal or peat (OK, fossil fuels) and got up when the sun came up and went to bed with the sun as well. In, fact a large part of the world’s population still lives like that.

Things altered with mechanized industry and night shifts. Electricity providers sold the populace on being able to do more instead of just sleeping when it became dark, and the Western population got hooked on buying huge amounts of energy, mostly electricity and engine fuel, which was usually produced from oil and coal.

This idea soon travelled around the world and with rising prosperity came emulation and other countries wanted the same. Now we are in the sad situation where we have to confess that we rode the fossil fuel gravy train to its last stop without thinking about what we would use when fossil fuels ran out.

This is where the typical citizen comes in. You have to think about how you want to draw energy in the future. Do you want to be powered by keeping sucking unrenewable resources out of the planet, or do you want to have as little to do with it as you can? Would you rather have everything you have now, but know that the resources that are powering your lifestyle are renewable?

If, like millions of others around the world, you would rather say ‘No!’ to traditional power production methods, then you have to take a stand. But not only in words, you really have to do some something about it physically.

This will mean investing a lot of money up front, which might not be a problem for you or you may even think that taking a stand is worth looking for a bank loan. These are admirable sentiments, but I would like to propose that there is another way to self-sufficiency.

You could build your own!

Why not? The technology has been around for decades and is fairly easy. Most reasonably competent teenagers can put together a bank of photovoltaic cells into a solar panel and then plug that into your home’s electrical system. And if a teenager can manage it, so can you. All you (and the teenager) will require is a solar panel kit and a schematical diagram. A plan in other words.

A solar panel kit can be bought locally from a Do-It-Yourself store or from the Internet. A typical solar panel will take a few hours to assemble and will produce 100 watts of electrical energy. The electricity produced from these panels is then passed through an inverter that changes the current from DC to AC, making it utilizable by household appliances and the utility grid.

Do yourself and the planet a favour, get off the grid and start saving money and the planet’s resources, you will be surprised how straightforward it is once you get going. And do not forget, you can do it in stages of, say, one 100 watt panel a month until you hit self-sufficiency. It is not a question of ‘All or Nothing’.

Life Off The Grid

You can live off the grid. You only have to have the grid to purchase electricity if you cannot generate your own. Living on the grid has made too many of us lose our self-sufficiency. We slavishly buy energy off the big suppliers and pay through the nose for it at the end of the month.

How many days a month do you have to work just to pay your electricity bill? What could you do with that time or money if you did not have to use it to pay for your electricity?

The fact is that you can come off the grid and you can even sell your surplus, home-made electricity back to the grid. This is not likely to make you a lot of money, but it is a nice feeling after only paying out for decades. However, the savings of life off the grid do not end there. There are ecological savings and the saving of human life too.

Soldiers would not be sent to fight for oil if we were not so reliant on it. The fact is, that if more people came off the grid, the price of oil would fall, because demand would go down and the oil-producing countries that think they have a strong hold on the West would lose their power. And that can not be a bad thing either, can it?

It is easiest for people who live in their own houses to come off the grid. They have more jurisdiction over their own property and can make their own decisions about what to do with it. Drill a hole here, cut a hole there – that sort of thing. Alterations or home improvements. Life off the grid is also most beneficial for families as they use the most electricity.

The most common techniques of attaining a life off the grid is by the use of solar panels, hydropower and wind turbines or even good, old-fashioned wind mills. These devices are still expensive to buy and very expensive to have installed. A recent study in the UK estimated that it would take 10 years to recover the investment of a professional installation of energy-making devices.

However, you could remove the expensive labour element by making and installing the units yourself! This opportunity is accessible to anyone in the world as the diagrams and plans for making these units are available on the Internet from specialist alternative energy web sites and the components are practically every day items.

You will be able to get them in a hobbyist or DIY store. They are also very easy to put together – most teenagers could do it and so could you. If you do not like that route, you could purchase a self-assembly kit.

Once you have started to become free of the grid, you can make life off the grid even more rewarding by renewing your appliances, as and when necessary, with low energy models. If you approach life off the grid wisely, you could add new energy producing units every month until you do not get any electricity bills any more and then whatever further savings you can make will be sold back into the grid.

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

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 fact is that fitting 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 section of society as big as the working class and which can afford to pay for its own electricity anyway. These programs leave the preponderance of the members of society stuck with the grid. The new British proposal FITS is like this.

Other countries have so-called ‘Green Options’, which means that you can choose to draw 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 stuck in the system of being on the grid and being subject to price rises and black-outs.

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 have to take a drastic 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 goal. The fact is that it could take you years to get off the grid, and by then white goods will be using less electricity than they do now anyway. You can also sell your surplus electricity back to the grid for real happiness.

The cost of the professional installation of solar energy systems can be prohibitive and take twelve years or more to recoup, but if you assemble and install your own bank of solar panels, you can more than half that figure. In fact, it is possible to reduce 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 competent teenagers can do, given the right drawings or schemas.

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

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

What a dream!

Make A Wind Turbine For Free Electricity

I am sure that you would like to come off the electricity grid. Who would not like to put a halt to those growing monthly bills? The trouble is that no one is stepping up to the plate to tell us how to do it. Politicians are just starting to ring the alarm bells even though they have known about the predicted oil shortage for decades – like we all have.

The difference is that we are not being paid to take the right decisions for the country like they are. We look to our elected representatives for guidance, but there is not much available. Yes, there are a few subsidies on hand for the installation of replenishable energy sources, but they will only benefit the middle and upper classes who can have the funds for them anyway. They will also benefit the firms that sell these devices, because they will get their asking price from the state, which will pay with poor people’s taxes. Great!

Where are the government hand-outs (not money) informing people how they can assemble and fit their own solar panels and wind turbines without having to make somebody else rich by doing it? Surely, if the government were serious about sustainable energy, it would have worked out a way to allow average people to help themselves?

You can actually build a very effective wind turbine from scrapyard parts and components from a hobbyist store like Radio Shack. But no politician is telling you that. They want you to spend $45,000 on a green system and even better if you put it on your credit card or overdraft.

The reason why you should consider completing your own wind turbine is that you can probably get the parts for less than $500. It sounds like a massive saving and believe me, it is, but you will have to do a lot of work to carry out yourself, instead of lying back and watching a contractor do it for you. But I should imagine that you realized that already, eh?

I know that ‘building your own wind turbine’ sounds unbelievable, out of the normal person’s capabilities, but in a way that is because we have become too focused. When asked your job, you might say that you are a data enterer of a maths teacher, a miner or a writer, but that is NOT all that you are and certainly not all that you could be.

Take a deep breath and buy some plans to build a wind turbine or, if that is too intimidating a solar panel. Believe me, once you have built one, the next one is far easier and the icing on the cake, is when your energy device is standing there, hooked up to your home power supply and giving you a bit of independence from the grid.

It will inspire you to make another one and become even more independent and, who knows, you may even stop what you are doing now and build units for your neighbours. you may become an eco-warrior!

Solar Energy Panels For Home Or Business Use

It is almost high noon on the energy front. Oil, the substance that is used to produce most of the world’s electricity is becoming too dear to use to produce electricity for home consumption. Even if you think that there are lakes of oil left, which might be true, the main reason they have not been exploited yet is because it is too costly to get out. The only thing that makes it a viable concern is the high price of oil on the market.

Therefore, it stands to reason that oil prices cannot go down in the long term, which means that our electricity and petrol prices will stay high and will probably keep going up. Add to that the fact that manufacturing is moving to the Far East and the fact that immigration is rising and the result is lower wages in the West. The probability is that the average national wage will not rise as rapidly as the price of energy.

So what can you do about it? Well, while commodity prices are certain to keep increasing, one thing has always kept falling and that is the cost of new technology. Or to be more accurate, slightly old technology. Cutting edge technology is always expensive, but after a few years the price tumbles, as we saw with desktop computers and as we are seeing with laptop computers now.

The same trend is at work with solar panels. They are far less expensive now than they were a few years ago and they are far more responsive too. And did you know that the components that are used to make solar panels can be purchased from plastic bins at most DIY and hobbyist stores like Radio Shack? If you knew what to buy you could literally go out and bring back enough bits and pieces to make a few solar panels the next time you go out for a loaf of bread.

So why are we not doing it? We did not know that was feasible? Nobody told us? We are not technically minded? We do not have the skill?

OK, all those reasons sound valid. Nobody has been telling us, but the fact is that it is easy to construct solar panels and not that dear any more. Professional installations are still dreadfully expensive – about $45,000 -, but you can do it yourself. There are two approaches you can take.

You can either get a schematic drawing, a plan, from a hobbyist shop or the Internet, buy the components and make your panel or you can buy a self-assembly kit. Really, there are kits about that teenagers can assemble as easily as they do a plastic model airplane. ‘Locate and insert part number 44 into the main board number 3′ – that sort of simple.

If you are fresh to the world of solar energy, then you may be asking yourself how solar energy panels work? Solar energy panels are also known as photovoltaic panels; photovoltaic meaning electricity from light. Solar energy panels work by collecting protons from the sun, which dislodge neutrons, and thereby generate a flow of electrons or electricity. This electricity can either be stored in batteries for later use or used directly.

You can utilize solar panels to heat your pool, run your workshop tools, power the greenhouse lights and fans or if your system is large enough, replace grid electricity in your whole home or business. Most solar energy panels are designed to last upwards of 20 years but involve little to no upkeep.

There is a drop-off of the power supply after about 10 years of about 10%, but over the life-time of the solar panels, the energy savings made are enough to recoup the original cost of the system and more. Furthermore, costs are dropping while energy prices are rising. It already makes financial sense to switch to solar energy power.
