Solar Power History

“I have no doubt that we will be successful in harnessing the sun’s energy… If sunbeams were weapons of war, we would have had solar energy centuries ago.” These are words of Sir George Porter (December 1920 – August 2002), Nobel Laureate in Chemistry, which today is a reality. The energy which is derived from the sun and responsible for practically all life on earth is today harnessed for generating heat, light, power and electricity for meeting global needs for alternate energy resources. Yet the concept and use of solar energy is not new. Early Greeks, Native Americans and Chinese have used it to their benefit by orienting their home and hearth toward the sun for centuries. The term solar power has today become synonymous with solar energy which is obtained by converting sunlight to electricity.

While the application span of solar energy now encompasses the domestic (including cooking and heating), commercial, industrial, farming, aviation and surface transport sectors, there are several technologies which are in place to generate this type of natural energy. In fact, solar energy has now found its place in every day use items like cars and calculators.

Back in historical times, solar energy may not have been known by any name, but its use has always been the backbone of agriculture ever since man learned to till the land and grow food or crops. We have seen the importance of this energy in medieval Europe where farmers deployed elaborate agricultural strategies to get the maximum out of sunlight for the wellbeing of their yield. Even today, sunlight optimization is the primary agenda for anyone who is involved in farming or gardening, starting from planning their planting schedule, strategizing row orientation, altering plant heights between rows, etc.

Man has always built his home to take the most out of available sunlight. Critical use of solar energy is evident in today’s urban building designs where not only the building orientation but window placements and proportions and building materials are chosen to harness the most of this invaluable energy form. The importance of solar energy was realized by first century Roman architect Vitruvius who commented that home designs must be made according to the diversity of the climate of that particular region. Solar energy when deployed to supplement day lighting techniques, homes can save enormous amount of resources by making maximum use of sunlight during all the time that it lasts. The importance of solar lighting or natural light was appreciated way back in 6th century Rome and later corroborated by the British in 1832. In fact, it was only in the 20th century that artificial methods became the primary source of interior lighting. The energy and oil crises during 1973 and 1979, made people re-focus on natural lighting, but soon the interest died due to cheap available sources of energy.

One of the areas where solar energy is most widely used today is in the field of solar thermal applications, where the applied technology uses heat from the sun to heat water and space; for ventilation; for processed heat required for industrial applications, cooking, for water distillation plants, etc.

Solar energy is for everyone simply because the sun shines in every corner of the planet. In fact, the history of solar energy can be traced back to the Greeks that were then passed on to the Romans which marked the first people to ever use the passive solar design.

Passive solar design is a way to warm the home based on the dwelling’s design. They may not have had glass windows back then but their architecture made it possible for the people to use the sun’s rays to light and heat indoor spaces. As a result, there was no need to burn food that often which was in short supply.

In 1861, Auguste Mouchout invented the first active solar motor. Unfortunately, its expensive price made it impossible to produce commercially. Less than 20 years later, Charles Fritts invented solar cells which will later on be used to power homes, heaters, satellites and other devices today.

Since what he invented was very primitive, other people experimented on solar energy. One such person was Albert Einstein who won the Nobel Prize for physics in his research on the photoelectric effect which is a phenomenon associated with the generation of electricity through solar cells.

In 1953, Bell Laboratories which we know today as AT&T labs developed the first silicon solar cell capable of generating a measurable electric current. Three years later, solar cells ran $300 per watt. With the Cold War and the Space Race on, this was used to power satellites and crafts.

But the biggest event in the development of sola energy occurred during the oil crisis of 1973. This prompted the US government to invest heavily in the solar electric cell that was developed by Bell Laboratories 20 years ago.

By the 1990’s, research towards solar energy came to a standstill as the price of oil dropped in the world market. Funds were diverted elsewhere and the United States which was probably the leader in this form of alternative energy was soon surpassed by other nations mainly Germany and Japan.

In 2002 for example, Japan had installed 25,000 solar panels on rooftops. Because of that, the price of solar panels went down as the demand for it was on the rise. To date, solar energy is growing at a modest 30% per year.

Although there have been improvements in solar energy, its fundamentals are still the same. The sun’s rays are collected and then converted into electricity. Aside from powering homes or office buildings, the technology has been used to power aircraft, cars and boats.

Unfortunately, none of these have been made available yet for public use. We still rely heavily on oil for electricity, gasoline for our cars, fuel for planes and ships.

In fact, the US is one of the biggest oil users in the world. To prove a point, the department of Defense consumes 395,000 barrels per day because of the wars being fought right now in Afghanistan and Iraq which is almost the fuel consumption of an entire country like Greece.

This has to change because our oil reserves are almost depleted and many experts believe that global supply for these non-renewable resources will be gone before the end of the century. We have to do our share to push for renewable energy and one of them happens to be solar energy.

Solar garden lighting is the latest buzzword for exterior home decorations. They are increasingly becoming popular because they do not have any maintenance costs, nor do they generate electricity bills. However, there is a common misconception about solar garden lighting. Whenever we hear the word, a picture of a bulb or garden lights come to the mind. First, solar garden lighting is far more decorative and presentable than the average bulb. Second, there is much more to solar garden lighting. Some of the types of solar garden lighting are discussed below:

* Solar Patio Lights: If you have ever walked into a resort or the party lawns of five-star hotels, you will know how beautiful it makes the surroundings when your entire walkway is lit up with bulbs. Now the luxuries of these deck lights are no longer the exclusive domain of expensive hotels or Oscar night. You can bring them home with patio lights. They will make your garden beautiful, and your evening walk will be a lot different than what it has always been.

* Solar Security Lights: Solar lights, although aesthetically appealing, can do much more, apart from decoration. They have great functional utility and are very useful for security purposes. The first advantage is that since you do not have to worry about an electricity bill, you can install plenty of solar garden lamps. Since each of these lamps is brightly lit up, it almost creates broad daylight. This, in itself, scares thieves and crooks from trying to barge into your peaceful existence. Solar garden lighting makes your home safe.

* Solar Shed Lights: Bored at home! Perhaps you should build a shed in your garden. Put a couple of swings in it – a rocking chair and a tea table. You will have the perfect atmosphere for almost everything. Right from your band practice to your aerobic routine, everything can be done in the midst of nature. Breathing in fresh morning air also makes you healthy, and the evening breeze has been known for ages to provide rejuvenation after a tired day’s work. But to do many of these activities, you require light. This can be accomplished simply with the use of a solar shed light. It has been designed for this purpose and can make the quiet place outside your home vibrant with life and energy!

* Solar Fountains: Apart from lights, you can also get a solar-powered water fountain installed. Of course, if you put lights around it, it will look spectacular at night!

There are several other varieties of solar garden lighting available. It is also ecofriendly. So on one hand, you are saving money on electricity and, on the other, lighting up your house with something that will not throw the world into darkness. Being completely sustainable and renewable source of energy, solar energy saves both you and the world a lot of money. It will cost lesser than what was earlier considered a requisite to light up your life. Such simple improvements will work wonders for you, and you will certainly cherish saving nature as well as your pocket!

Now is the perfect time for you to smile when you are gardening because you do not only get to place or decorate your garden with plants, trees, flowers or other ornaments but you also get to place or decorate it with Solar Garden Fountain.

Solar Garden Fountain is a fountain that is powered by solar panels, which get energy from the sun rays to make it possible for your fountain to function or to work and give you that lovely waterfall effect. The water show that you will be getting in your garden will be none other than this fountain itself. Thus, you will no longer worry about any cord lying around because the only thing that will make it work is the sun.

Another thing is that by putting the Solar Fountain in your garden, you are providing a home and a birdbath for the birds. There is no doubt that they will surely appreciate your little gestures of kindness and thoughtfulness to their existence. The birds would love to enjoy your fountain the way you enjoy it as well.

In addition, you will be able to establish a focal point to you garden. If your garden used to look ordinary and boring, well, now it looks more lively and happy. You will feel comfortable and very satisfied as well. In addition, you will also feel good inside. Just by staying in your patio or in your garden, you very well know that this will relax you and give you more time to unwind. Well, now that you have this fountain, you have more reasons and benefits to enjoy from.

Furthermore, the secret to Solar Garden Fountain is that you should place it in an open space outside your backyard. Make sure that you are able to avoid it from trees or falling branches and as much as possible avoid shadows. The shadows are boundaries that will prevent your fountain from working beautifully because the sun can no longer reach to the solar panel if it is located or installed together with the fountain. However, if you have separate solar panels from your Solar Fountain then that will give you a hint that you should really place the solar panels in an open space where the sun can provide enough sunlight or ray of sun for it to work properly and beautifully. Now you will have more time to enjoy your stay outside and see the wonders of the work of nature. You will not only see the flowing water but you will also see the birds. In addition, you will also see the great beyond on your garden. Now you see what you do not usually see and that is your home garden. Now you have established an outdoor space which you can truly appreciate and that is something that you will treasure. You should be thankful of the Solar Garden Fountains that make gardening easier for you to create a garden with a twist.

WOW! We are almost all in agreement about at least one form of renewable energy; ninety per cent of Americans think that builders should be offering the option of solar power in new homes.

For those unsure of the term: solar power is the term used to describe the resulting energy from the conversion of sunlight into electricity. In order to do this, the sunlight must first be ‘captured’.

Because there is always (so far!) sunlight, this is called a renewable source of energy. This means once we have perfected the technique to turn the sunshine into electric power, we can always use that technique as there is always sunlight and it is always free.

Solar energy in a primitive form has been used for centuries by various civilizations. Nowadays with technology at such a sophisticated level, solar power can be used to provide heating, lighting and electricity.

Water heating is easy to install in new homes as the panels for it are usually placed right in the roof. Believe it or not, America first had solar water heaters as early as 1890! In many climates the sun can provide up to 75% of domestic water usage, so it makes sense to build these units into new homes.

The more people that request the option of solar power in their homes, the more mainstream it will become. A builder can often just install the pre-wire kit during construction, so that it is easy for the owner to add on the panels later, if desired.

Solar power also saves the home owner from paying large electricity bills, as the domestic electric power will only kick in when the solar power has been used up. Increasing energy costs make solar power look attractive – apart from the fact that it contributes to a healthier planet.

Due to the steadily gaining popularity of solar power, the price of panels is predicted to be halving within the next five years. Many states offer generous subsidies and rebates to assist the American home owner in making the right choices about energy and there are also federal incentives to look into.

Designs are becoming more and more attractive as the market expands. Whereas once solar power gave a home the look of having something stuck on your roof, nowadays designs can actually enhance the look of a home.

Israel leads the world for total percentage of domestic use, with 90% of its homes using solar power. China, with its large population deploys 80 % of the market share of solar hot water systems. In USA solar power is most popularly used for heating swimming pools.

Internationally, the use of solar power in swimming pools and low temperature applications such as domestic hot water and space heaters, is the most common usage, this is because the power is most naturally converted into heating.

In fact, solar power has been used to power a car that ran for over 3,000 kilometers (in Australia) and a boat that crossed the Atlantic (in UK). Solar energy has also been used to cool houses and to cook with. However, by far the most acceptable method of using it at the moment is solar water heating.

There are many American companies listed on the Internet if you wish to find out how your home would convert to solar power.

The first and possibly most important component in any solar panel system is the solar panel. Modern photovoltaic panels provide an almost perfect solution for any homeowner wanting to power their home independently with the free energy the sun provides. The newer solar panel design used today is durable, less expensive and efficient enough to make solar power for homes a preferential option. Over the years these solar panels for homes have improved dramatically through changes to their design and improvements to the formulations used in making the solar cells which are contained in weatherproof enclosures. Because of these innovations, modern types of solar panels for homes are able to generate far more power than older versions and are actually over twice as efficient as panels produced only a few years ago. They are also built to higher standards, which allow them to last on your home years longer than older versions and further extend their value.

How Solar Panels Work

The way these solar panels for homes produce this free power is through a chemical process called photovoltaic conversion. This process occurs when certain chemicals are placed in direct sunlight and can generate a small current as a result of this exposure. Inside the typical solar panel design there are a collection of solar cells that do this photovoltaic conversion. These solar cells are typically grown out of a silicon crystal formulation that allows them to do a very efficient job with this conversion. Over the last several years newer formulations for growing these solar cells have been developed that allow them to generate far more power from the same sunlight than ever before.

The 2 Types of Solar Panels

Basically there are two types of solar panel technologies that can be used in these home solar power systems and both of them have different advantages. The most efficient type of solar panel design is called a monocrystalline and is also the most expensive. This type of solar panel is built from solar cells that are grown as a single large crystal and do the most efficient job of converting sunlight to power. Even though this style of solar panel design might seem too expensive for your needs, it’s actually more cost effective over the total life of your system. Because the monocrystalline solar panel design can deliver more solar power for homes with the same sun exposure as other panels, you’ll need less of them on average. This can save you a substantial amount of money on installation and equipment costs.

Polycrystalline Vs. Monocrystalline Solar Panels

The other solar panel design is called a polycrystalline design and includes solar cells that are made from smaller fragments of silicon that have been joined together to form one larger crystal. This type of solar panel design is less expensive than the monocrystalline, but will produce less power as well. Even still, these solar panels for homes are used in many installations and can provide a lot of power for considerably less money than the monocrystalline solar panel design.

One recent innovation that has been released in the last few years is solar shingles that can be used in place of traditional solar panels for homes. These solar shingles differ from these other types of solar panels since the solar conversion material is actually applied to the surface of the shingle and doesn’t involve a traditional solar cell. While these are not yet as efficient as the other types of solar panels, they do hold a lot of promise for the future as development and improvements continue.

Have you any idea what’s the most cost effective way to put solar energy panels on your roof if you do not want to spend too much money? Make them yourself. Each of these panels will cost you less than $200 if you make them in the right way.

Other than saving money on your solar power generator hardware, you can also save thousands every year on electricity bills. The sooner you start learning how, the faster you can grab these savings for yourself. I’m pretty sure you’d rather use the money on a good vacation than pay your energy bills, isn’t it?

There are many more benefits than these. When you use solar energy, less fossil fuel is burnt. As a result less greenhouse gases and toxic elements are being released. At present, global warming is a serious issue that affects the world at large. A government or an individual do not have the power to solve this problem. All of us have to chip in our efforts. Using solar energy can be a good way all of us can achieve that end.

If you love the benefits of using solar power and want to build them yourself, here are the basic steps to do it:

1. Get enough solar cells so you can join them together in an array to produce sufficient voltage per PV panel.

2. Get some plywood or metal and build a panel frame to house the solar cells.

3. Cut a piece of glass (or acrylic) to cover the panel frame. This piece of glass protects the solar cells from precipitation and allows sunlight to enter at the same time.

4. If you are using solar energy panels to charge up a battery bank, you’ll need to buy a suitable charge controller.

5. As your wire up your hardware to the mains, you’ll have to get an inverter with sufficient power rating so direct current (DC) from the solar energy panels can be converted into alternating current (AC).

With the brief outline above, you can get an idea of how to make your own solar energy panels. But if you are serious about making a professional looking set of photovoltaic panels, you have to know how professionals build them.

There are many excellent DIY guides that spill the beans on techniques that work. WIth these tips, you can build each photovoltaic panel for less than $200. These panels can also last for more than 25 years if you build them properly.

If you are a beginner or have never handled DIY projects before, these guides are the right resource for you. Even if you have extensive experience building DIY projects, you’ll find valuable insider secrets that can help you save tons of money as you bring your project to completion.

We want to congratulate you on your decision to heat your house with alternative fuel. If you are in the final stages of choosing a stove or fireplace that may burn quite a lot of renewable energy sources, then we’re glad we will help. Making an funding in a biomass range means you want save on fuel costs, the environment, and our dependence on international oil. In return, we want you to get probably the most out of each hard earned dollar, and the fuel you select will make a difference.

CHOOSING QUALITY CORN AND AGRI-FUELS

Choose high quality fuel, and you’ll save cash by heating extra efficiently. If someone told you that you might burn something in a biomass stove, that’s not fairly true. Yes, there is amazing flexibility in fuel sources, but it’s essential to make sure you’re using the fitting fuel on your appliance AND a top quality fuel source.

It is pretty easy to explain what to do with agri-fuels comparable to corn, wheat, oats, barley to say a few. If you guantee that the gasoline is clear and dried down below 15 percent moisture (this is required to guarantee no spoilage anyway) you might be good to go. You do have to ensure that your equipment is licensed to burn these fuels (check on the label) and provide storage where the gasoline can keep clean and dry. Our best recommendation is to solely purchase sufficient fuel for the winter so nothing is left over to spoil in the summer high humidity months.

IDENTIFYING PREMIUM WOOD PELLETS AND BIOMASS FUELS

Wood Pellets and other Biomass fuels are a bit harder to establish as being the premium quality fuel that you desire. Most of these kind of fuel may start out as premium high quality when manufactured by the gasoline supplier, but when this fuel shouldn’t be stored inside with climate managed facilities, it would take on moisture and the fuel begins to fall apart. This is evidenced by a high proportion of fines within the fuel when poured out of the bag. You ask, how can I stop getting dangerous fuel? Always use a good supplier. Fuel resellers that specialize in selecting and correctly storing gas are your finest bet. Inspect the gasoline when purchasing and if it is bad stroll away. If you get dangerous fuel take it back to your fuel provider and demand one thing better.

There can be differences in fuel quality and consistency so it will be important that you purchase an appliance that is designed for Flex-fuels so that your appliance will have the ability to adapt to changing fuels. When you might be doing your research check for multi-fuel capabilities and the flexibility to burn excessive ash content fuels. Last but certainly not least, just remember to are screening your fuel, vacuuming out your hopper to do away with excess fines, and maintaining your firepot system on an everyday basis. You will enjoy bother free operation.

Renewable energy marketing contains advertising discount of energy costs. Sustainable solutions partake in the usage of natural clean drive such as solar, kinetic wind and water or tidal energy. Green energy advertising and marketing emphasized the usage of environmental friendly source that might help sustain lives of future generations. It is confirmed by experts that large scale manufacturing of reusable energy is price efficient and helps countries save up thousands and thousands and thousands and thousands of dollars. To show how green energy reduces power in a communal and individual level, listed below are seven proofs for you all.

First, sustainable options cut down half of energy consumption with out compromising energy usage. Since water heating and warming homes is essential especially to European countries, it has all the time been and all the time will be a part of their day by day living. Imagine allocating the electricity utilized in warming houses and heating water for consumption to other essential activities within the homes.

Clean energy lessens carbon emission. This has been stated in numerous renewable energy marketing campaigns. What does reduce carbon emission do within the earth’s ambiance anyway? Why is it important? Lessened carbon emission helps cool the earth’s atmosphere. Greenhouse impact is the change of temperature within the earth’s atmosphere. To cool down the atmosphere and convey it to a extra favourable temperature might help change the future.

Third, green marketing emphasizes using free energy. Wouldn’t or not it’s nice to use the energy that’s abundantly accessible to us without using heavy machinery process electricity? Installing renewable energy generators could be costly from the start but on the long run it will save up a whole lot of dollars in electrical consumption.

Also, nature-based energy doesn’t pollute the environment. Once again, it’s the green flag that reigns supreme. To preserve the atmosphere is to protect the future. People will pay millions to reconstruct forests but an important thing of all is how folks help protect the environment and keep away from the reconstruction.

And one other thing, sustainable energy mills need to not be expensive. There are several guide books that offer Do It yourself solar panels that work even if you do not want to shell out the additional cash. Even clean energy companies offer easy solutions to save lots of energy without the additional charge.

Not to mention, pure is in. To adapt natural lighting on homes and making use of the accessible light outside the properties and offices during daylight is sufficient to save 80% of energy consumption. Imagine incorporating other clean energy solutions to your houses and office to chop down the costs and to help contribute to the environment.

Lastly, Mother Nature provides back what’s finest to you. If more and more people put their trusts to renewable energy companies, not only would it help preserve the environment but the non-sustainable energy sources as well. Imagine the world free from the green house effect or at the very least partially free from it. There wouldn’t be need for offices to run in air conditioning and the local weather change won’t be as drastic as we face it today.

There are many energy sources today which might be extremely limited in supply. Some of these sources include oil, pure gas, and coal. It is a matter of time before they will be exhausted.

Estimates are that they’ll only meet our energy demands for another fifty to seventy years. So in an effort to seek out alternative types of energy, the world has turned to renewable energy sources as the solution. There are many advantages and disadvantages to this.

Renewable energy sources consist of solar, hydro, wind, geothermal, ocean and biomass. The commonest advantage of every is that they are renewable and cannot be depleted. They are a clear energy, as they don’t pollute the air, and so they don’t contribute to global warming or greenhouse effects. Since their sources are natural the cost of operations is reduced they usually also require less upkeep on their plants. A widespread disadvantage to all is that it’s difficult to provide the giant quantities of electrical energy their counterpart the fossil fuels are in a position to. Since they’re also new technologies, the price of initiating them is high.

Solar energy makes use of the sun’s energy. It is advantageous because the systems can fit into current buildings and it doesn’t affect land use. But for the reason that area of the collectors is large, more materials are required. Solar radiation can be controlled by geography. And it’s limited to daytime hours and non-cloudy days.

Wind energy uses the ability of the wind to provide electricity. Although it’s the largest job producer, it is reliant on sturdy winds. Wind turbines are large and, although you need to use the area beneath them for farming, many think about them unattractive looking. They are also very noisy to operate. In addition, they threaten the wild hen population.

Hydroelectric energy uses water to supply power. This is essentially the most reliable of all of the renewable energy sources. On the down side, it impacts ecology and causes downstream problems. The decay of vegetation alongside the riverbed can cause the buildup of methane. Methane is a contributing gasoline to greenhouse effect. Dams also can alter the pure river flow and have an effect on wildlife. Colder, oxygen poor water can be released into the river, killing fish. And the release of water from the dam may cause flooding.

Geothermal energy makes use of steam from the Earth’s floor to generate power. It makes use of smaller land areas than different power plants. They can run 24 hours per day, day by day of the year. Disadvantages are that it is very site specific and, alongside with the heat from the Earth, it might also bring up toxic chemical compounds when obtaining the steam. Drilling geothermal reservoirs and discovering them may be an costly task.

Biomass electrical energy is produced by means of the energies from wood, agricultural and municipal waste. It helps save on landfill waste but transportation may be expensive and ecological variety of land could also be affected. In addition, its process needs to be made simpler.

Ocean energy is a clean and considerable energy form. It does, however, have excessive costs. Ocean thermal energy also requires close to a forty diploma Fahrenheit difference in water temperature 12 months round. In addition, development and laying pipes can cause injury to the ecosystem.

There are many benefits to using renewable energy sources. There are also some disadvantages. The truth is energy demands will proceed to increase. Through analysis and development, as properly as, new technologies, the hope is lots of the disadvantages of renewable sources of energy may be eliminated and we can successfully incorporate it into our power supplies.

Renewable energy indeed is effective and has helped thousands of household nowadays in cutting their electricity bill. It is not necessary that we will be enslaved by electricity suppliers with their expensive electricity.
