How to Find Cheap Solar Cells with Minimal Effort

Homemade solar cells are quite expensive in both time and money to produce by yourself.

If you are not planning to make your own cell then the alternatives left are ” either to find them (possible only if you have a friend at a solar company) or otherwise you will have to buy them.

The first place you can look to find low-cost solar cells is at the hardware store. Highway patrol is another good source that sometimes can have solar panels left over from car crashes.

The above two ways are possibilities of buying cheap solar cells. Other than that is a way where you can get them easily – its through eBay. It works like this:

First, search eBay for broken solar cells or chipped solar cells which will throw open a number of bids.

Next, look for less-damaged cells and those that are relatively the same in size. This will enable you to gather everything on one panel and choose how many you need to buy.

In case you are keen on the more costly option, search for transparent cells on eBay, or look for latest cells by reputed companies like Evergreen Solar. This is a costly choice; nevertheless, this will enable you to assess your estimated power output in order to buy the exact number of cells.

How much should you expect to pay?

Depending on the state of the solar cells you buy off eBay, the price per cell should be just a few cents.

Evergreen Solar Offers 100% functional and professionally produced cells which are very expensive. Still you should not increase your cents more than 10 for each individual cell.

It is probable that shipping expenses for the cells may cost you more than $20, which again depends on the location of the vendor and shipping procedure.

You are likely to pay $ 30- $ 50 for 500 chipped solar cells, which is perhaps not sufficient to entirely cut down your electricity bill. But it is sufficient enough to reduce it and save you thousand of dollars per year.

Homemade Solar Panel and its Importance as an Alternative Energy Source

The people nowadays are becoming increasingly aware of the advantages of homemade solar panel. Needless to say that as the cost of energy rises, people are thinking of different ways to make their lives easier through practical decisions. Energy alternatives such as solar panels are not only helpful to the environment; they can also help cut down the cost of electricity in your home.

Solar energy had already been considered way back in 1970?s when the first oil crisis had been encountered. People are aware that it was only a matter of time and their dependence on oil will be causing serious problems. Still, as years pass, the cost of oil went down again and as expected, the measures that were initiated about solar energy had been set aside.

Nowadays, as we look back to what happened during those times, we can say that things could have been better if only the programs on solar energy were pushed and implemented. The cost of oil at present had skyrocketed which has become a major concern and every person is asking if there are better ways to make life easier. In this case, solar panels that are homemade can be beneficial.

How do solar panels work? Solar panels function by taking the most renewable energy source and then convert it for use in the homes. If you are familiar with a hand-held solar calculator, then you would somehow have an idea about the principle of solar energy. This similar principle can be applied in bigger applications.

A solar panel which is homemade is a cheaper and a more practical alternative to an expensive basic solar panel system. The reason why a lot of people do not consider using a solar panel for their homes is because there are worried about the cost. A basic solar panel system can cost around $40,000 ? this is what most people choose to believe in. However, there are far better alternatives which do not cause much but can serve its purpose.

A basic solar panel system may be costly but the important thing is that you have a more practical option. This is through a home-built solar panel which only costs around $200. The internet is the most reliable source of information regarding the materials and instructions. There are numerous websites that feature easy steps so you can start your project.

With your very own homemade solar panel, you can save money from heating and cooling bills caused by the big oil companies. Moreover, you will be doing the planet a huge favour. Remember that the leading cause of pollution is fossil fuels and 90% of the electricity comes from burning fossil fuels.

Solar panels can help address this problem through energy conservation. To learn more about homemade solar panels, take the time to visit my blog site.

Hydro Power – Why We Need Hydro Power

Using the water’s power is an age-old phenomenon. Over the years it has been employed for irrigation and working a variety of machines, including water-wheels. But today, it is used more importantly as a alternative energy source.

Nowadays hydro-power is generated in 3 different ways: hydroelectric power, tidal power, and wave power.

Hydroelectric dams:

This form of hydro power accounts for over 90% of all renewable energy generated. Power is generated in large dams, where water is forced through large turbines.

The advantage of this type of power is that not only does it produce electricity, but the dam helps collect water for our use, so it’s a power and water source in one. Furthermore, the force of the water is so strong that megawatts of electricity can be produced to help power entire cities.

The disadvantage is the devastating effect dams can have on plants, animals and even humans. When dams are built they flood large tracts of land that were once occupied by various species and communities of people. Furthermore, the water-borne animals, such as fish can also be affected. An example would be salmon that are blocked from swimming upstream to spawn by the newly erected dam.

Using The Tides:

With tidal energy, hydro-power is generated as the tides comes in and goes out.

This has been achieved by France and Russia since 1966 in areas with a large tidal range, such as bays and estuaries. One of the systems of tidal power works by trapping water at high tide with a tidal barrage, then releasing that water in one quick burst at low tide. This gushing water drives turbines to produce power.

The only drawback with using such a system is that it only operates as the tide turns, which is every 6 hours.

A second, more recent, tidal system looks very much like an underwater wind turbine. Large windmill like turbines are sunk in shallow water, where they are slowly spun by shifting tidal water.

The nice thing about this tidal system is that the technology is advanced and derived from our land-based wind turbines. And water is much denser than air, meaning it takes only a small current to get the turbine spinning.

The problem is these turbines can only be built in shallow sea floors, where marine life can be damaged and other enterprises, such as oyster farming, is affected.

Wave Power:

Harnessing the power of the waves is the newest type of hydro-power. The system works where surface waves, are used to displace air, which is then compressed and release through turbines, that then spins to make electricity. Two type currently exist – the first is built along the shore-line, where waves constantly break, and the second is built on floating devices in the deep oceans.

Although this technology is relatively new, it has been estimated that there is enough energy in ocean waves to produce up to 2000 Megawatts of power.

But, like any renewable energy system, there are environmental implications. These systems can damage the various corals and other ocean species along our coastlines. And the hydraulic fluid used could cause major water pollution if it ever leaked out into the sea.

Closing thought:

Man has come up with ingenious ways to harness the power of nature to produce electricity, hydro power being one of them. Although it is an important renewable energy for the future, there is still much controversy over its long-term environmental impact.

Dubai – Fastest Growing City in the Persian Gulf Region

Dubai Profile According to official figures, 99 per cent of the residents of the small, once insular United Arab Emirates (UAE) reside in Dubai City. This makes the distinction between city and Emirate very small indeed.

Dubai is growing faster than any other city in the Persian Gulf region. New and luxurious hotel complexes, shopping centres and high-rise apartment buildings are being built daily. The face of this highly modern city with over a million inhabitants is constantly changing, yet always a bit eccentric. In addition to countless corporate headquarters, ultra-luxurious hotels and resorts, and high-end shopping malls, Dubai is also home to the largest indoor snow park in the world, fittingly called Ski Dubai, itself located inside a gargantuan shopping mall. Opened in December 2005, the temperature inside the facility at the edge of the Arabian Desert is a constant —1 °C, while the temperature outside soars to 40 °C under the merciless desert sun. It would seem that in the city of Dubai, anything is possible.

Oil — black gold of the Emirs.

Dubai has been governed for over 170 years by the Al-Maktoum clan. Under their leadership, and with substantial investment from Britain, the harbour of Dubai has become the most important commercial port in the Persian Gulf. The local inhabitants used to earn their living by diving for pearls. Their lifestyles changed drastically with the discovery of oil in 1966 and the economic boom that followed.

Persian Gulf tourist destination.

In addition to the oil industry, Dubais economy relies on tourism, banking and trade. Great efforts have been made to promote Dubai as a tourist destination. The most exclusive residential quarter of the Emirate now boasts a number of world-class luxury hotels, including the famous Burj At Arab, the Arab Tower. Designed to resemble the sail of a traditional Persian Gulf ship, the 54-storey hotel is 321 metres tall. It is the tallest, most expensive and most luxurious hotel in the world. Visitors can play tennis at a dizzying height on top of the helipad overlooking the Arabian Gulf 311 metres below. The Wild Wadi Water Park and Madinat Jumeirah shopping mall are located nearby in the suburb of Jumeirah. Then there are the Palm Islands, tear-shaped artificial land masses built in the shallow gulf waters. They provide additional land for vacation homes, villas and hotels. Several nearby Gulf islands await similar development.

The river that is not a river.

The wetlands known as Ras Al-Khor divide Dubai into northern and southern sections. Ras Al-Khor is not a river but a shallow inland bay. Small passenger ferries called abras carry people from one side to the other for a small fee, or traditional lateen sailboats can be rented for a more extensive tour. A protected national wildlife area, the Ras al-Khor is home to over 100 species of birds, including a resident population of 500 greater flamingos.

Tourism promotes restoration.

Most of the places of greatest interest to visitors in Dubais Old City are found along the Ras Al-Khor. Naturally, there are also many mosques in Islamic Dubai. The Great Mosque, built in 1998, is between the al-Fahidi Fort and Ras al-Khor. Al-Fahidi Fort was once the seat of the emirs of Dubai. Restored in 1970, it is now the National Museum. The Bastakia Quarter is one of the oldest parts of the city, making up the larger part of its historic centre. Having survived the twentieth-century building boom without sacrificing its ancient charm, the government now plans a complete restoration, including a museum, cultural centre, restaurants and art galleries. Houses in Bastakia are notable for their wind towers, a traditional means of air conditioning. Cool air currents are pulled into the centre of the house through vents and windows. The system is so cleverly designed that that even the smallest breeze circulates through the rooms below.

4 Steps To Calculating Your Home’s Solar Power Needs And Expenses

With green living becoming more and more important, many people are starting to install home solar power to supplement their power, and reduce their electric expenses.

But how much solar panel watt power do we need to say halve our power bills? And how much will that power cost us to install?

This is the process we followed, when calculating our home’s solar power needs and the investment required.

1 – What Is Your Daily Power Consumption?:

To do this, get your last 12 monthly power bills and calculate your average kilowatt hour (kWh) usage per month. The reason we use 12 is because our power consumption fluctuates with the seasons. The calculation would be to add up the power used over the past 12 months and divide it by 12. But if you do not have all your power bills, then simply use last month’s one.

Now take your average kwH per month and divide that by 30 to get your average kWh per day.

- Here is an example: Lets say the power used last month was 800 kWh. Your average daily usage would be 800/30 = 26.7 kWh per day.

- So if you want to cut your bill by 50%, then the amount of solar power needed is 26.7/2 = 13.4 kWh per day.

2 – Work Out Your Solar Panel Watt Requirements:

To do this, you first need to determine how many usable hours of sunlight your area receives per day. This is where a solar insolation map comes in handy – you can view one from our original article on our website.

Once you know your daily sunlight hours, go back to your daily kilowatt hours needed and divide it by the daily sunlight hours, then multiply it by a factor of 1.25 (takes into account energy losses from the solar panel watt wiring, battery , and inverter)

- From our same example, if we lived in California where it gets on average 5.5 hours of usable sunlight per day, the solar panel watt requirements are:

13.4 kWh required / 5.5hrs of insolation x 1.25 = 3.045 kW or 3045 Watts daily.

This indicates that our home solar power system must have the minimum capacity to produce 3045 Watts of power.

3 – Calculate Solar Panel Watt Costs:

This step will help you work out the cost of the solar panels needed to make 3045 Watts of power. At the moment the highest average cost for solar panels in the US is $4.85 per Watt.

- Following on from our example, the solar panels will cost 3045 x 4.85 = $14,768 to only halve our monthly power costs. This excludes the cost of wiring, charge controllers, batteries, inverters, and installation fees.

4 – Offset Tax Credits And Rebates:

Before you think you are going to have to fork out at least $14,768 for only 3045 Watt of solar panel power, you need to consider the effect of government subsidies and incentives.

2009’s Federal renewable energy tax credits came into effect from the beginning of the year, and coupled with the state-side incentives in places like Connecticut, California, New York and New Jersey, the cost of the solar power system will be much less.

- Continuing on from our example: If we lived in California, our state tax incentives would be about 20 % of the investment, and the federal rebates 40% of the remaining cost. So, our solar panels would only end up costing us:

$14,768 – $14,768 x (20%) – $14,768 x (1 – 20%) x 40% = $7,089.

Since there are many factors that go into calculating your solar panel watt costs, please only use our steps as a rough estimate. Some things were impossible for us to take into account, such as special offers by solar installation companies, where they offer you discounts on the full installation (including charge controller, inverter, battery, grid-tie electrician costs, etc).

However, from the example, you can see that for Californian to reduce their power bill by half, they would have to buy $14,768 worth of solar panels, costing them $7089 after rebates. A cheaper option would be to learn to source affordable and even free solar cells, and build your own solar panels. This can be done by following a relatively inexpensive step-by-step solar power manual, such as Earth4Energy.

Solar Lights: A Grand Upgrade That Is ReallyAffordable.

It was not so long ago that solar lights seemed like a great idea, but in real life they just couldn’t deliver on their promise. With an extremely short battery life and producing only a minimal amount of light, solar lights seemed less than prepared for prime time.

Solar lights today are completely changed from what was available on the market even a year or two ago.

The new generations of solar lights are better designed, longer lasting and much brighter than previous models. New solar lights are also cheaper, making them a better value all around.

Think for a minute about solar lights in terms we can all relate to: Star Trek. The original 1960s incarnation of the show featured some technologies which seemed impossibly advanced at the time like hand held portable communication devices and GPs systems which were already available to consumers a few decades later when the Next Generation series aired in the 1990s.

Solar lighting can also be compared to the great strides cell phones have made in the last ten to fifteen years. Cell phones used to be bulky, expensive devices compared to the extremely small Bluetooth-enabled headsets on the market now. Advances in battery and microprocessor technologies have made cell phones so portable and cheap that nearly everyone now carries one.

Batteries have been improved to the point that ultra thin batteries can now supply as much power as a battery many times their size just a few years ago.

These same technological advances have been used in the new solar lights that you see on the market. A one day charge in good daylight will let the solar lights shine for several nights now.

Lights have gone through technological advances as well. Instead of incandescent bulbs, solar lights now use highly efficient LED (light emitting diode) bulbs.

LED arrays used with a single reflector give solar lights the luminescence of a 220 volt incandescent bulb – but there are many advantages to the latest wave of solar lights over the older models:

1. The bulbs last for around 10,000 hours before giving out

2. LEDs require no maintenance

3. At a miniscule 3 watts of power, they provide comparable light at 90% higher efficiency than incandescent bulbs

4. LEDs are safe for use anywhere, outdoors or in

The efficient, low profile batteries in LED solar powered lights and the sophisticated photovoltaic arrays which use solar energy to provide non-polluting, free power for your outdoor lighting add up to a vastly improved solar light all around.

New generation solar lights are a low cost and efficient outdoor lighting system which offers versatility for outdoor lighting designs.

Solar lighting doesn’t need any sort of wiring, so they’re easy to install anywhere you want them. As long as they get enough sunlight to charge their batteries, they can be used to light gardens, walkways, decks and any other outdoor area.

You don’t need to worry about adding to your electric bill at the holidays, either. Remember the light show in National Lampoon’s Christmas Vacation where the power drain blew the whole electricity grid?

You can add attractive twinkling light to your holiday lights or for your outdoor entertaining in the summer.

Solar lights are also a great way to light your tool shed or garage; they are a reliable backup system which is always there for you in the event of a power outage.

Solar lights offer you the ability to install outdoor lighting anywhere you like which costs you nothing at all to use!

Solar power lights are gentle on the environment as well as on your finances.

Solar powered lighting is easy enough for anyone to install. These lights can be installed anywhere you like and moved any time you want to make a change in your outdoor lighting.

Solar powered security lights can give you peace of mind without hitting your pocketbook. Thieves prefer the cover of darkness in which to approach a house and break in. Solar security lights and lights in your garden will make that impossible. The lights stay on all night long and can’t be turned off by cutting the electrical wires. Even when you are away from home, your solar lighting is on the job, protecting your property.

Solar lights also make your home more attractive from the street. If you are looking to sell your home, these lights give your home added curb appeal when seen at night. If you were looking at homes, you’d probably think more favorably about a home which was lit with free, environmentally friendly solar lighting than one which was dark once the sun sets.

Solar lights use advanced technologies to provide homes with clean, free outdoor lighting that is a reliably solid investment.

Solar Lights: The Modern Technology That Saves You Money

Solar lights have become popular and are lights for today and the future. We have been using energy from the sun for as far back as I can remember, but it has only been recently that we can use this power in an efficient way. With solar lights, we are able to take another big step towards keeping the earth cleaner and safer.

Not only are solar lights able to be used in many ways, but are and will continue to be earth friendly too. The sun is a source of energy that is renewable and we can use the energy from it without causing more pollution to occur. Using solar lights allows us to light up our world without having to increase negative effects on the earth.

Lets get a clearer picture of how these gems of light work, in a nutshell. A small solar panel is affixed to the top of the light fixture, a much smaller version of the collectors we have all seen on rooftops. During the daylight hours the suns energy collects there and transfers to a rechargeable battery attached inside the fixture. The battery charges during daylight and after dark the energy releases to the LED (Light Emitting Diode) which gives off light until sunrise when the cycle begins all over again.

Solar lights are put to use in many ways today. Some use them in lovely gardens, to light up their yards, for lighting around pool areas, or even to light up a garage or sidewalk. For this reason, you can find lights that are decorative and fantastic for the purpose lighting, and others that are made to be functional. These lights can be easily attached on buildings or up in trees so that they beam down the light to provide lighting for a larger area. For lighting the ground, there are lovely lantern styles available to make it safe to walk in the dark. Even floating lights are available, adding beauty to a pond or even to your backyard pool.

Discard any thoughts of a complicated installation. Digging a trench or pulling wires from your home has no part in this. Your experience of placing solar lights will be as easy as pressing beautiful candles into a holder or hanging a picture on an already made hook. Each solar light stands as an independent unit connecting only to its energy source, the Sun.

The LEDs that are in these solar lights last a long time and they don’t take much power either. Usually the LED light will last just as long as the solar light fixture itself lasts, which is usually for years. Of course LEDs are a bit dimmer than other types of bulbs, so they use reflective surfaces in many cases, which helps to make them to appear brighter.

Solar lights are going to vary in costs. Some home improvement stores offer great prices, while a boutique with garden enhancing lights may charge a little more for the lights. No matter what you pay for them, you won’t have to keep paying for electricity to use the lights, since sun light doesn’t cost a thing. If you replace other lighting fixtures that use electricity with these solar lights, you will probably notice that you save some money on your electric bill.

There are so many benefits to using solar lights. Even during the winter when the days are gloomy, the battery will still get enough sun to charge them. The lights will go on and off on their own as long as the sun rises and sets. There is no heat coming from the LED’s either, which means your kids and pets are totally safe around them. If the power goes off, you can go outdoors and enjoy the light from your solar lights at the envy of your neightbors. They also benefit the earth, and they make great choices for your outdoor lighting needs.

Homemade Solar Power: Free Electricity and The Power Beyond

Solar Power is a household term for generations now. And with its advancement over time, it is no longer a surprise to us if we will be able to come up with our very own homemade solar power. Like the advent of just about any technology, however, this also comes with its own questions. With the help of knowledge about it, you are on your way to creating a possible solution to your energy dilemma, a homemade solar power.

It Works, But How?

Materials needed to making your own homemade solar power are solar panels, glass, and plywood to attach the panels together, copper wires, capacitors, transistors and a volt relay. Be sure to have a better understanding of every detail to ensure the best quality possible and to avoid any danger along the way with your very own solar power. It would help to consult an expert, too!

The Nitty-Gritty, Component-Wise!

Solar panels made up of a solar cell are the main component in every homemade solar power. The solar cell acts as a transformer of sunlight into energy. These designed solar panels are readily available in electrical and hardware stores. If you want the cheaper versions, the homemade solar panels, just ask for the spoiled cells and photovoltaic cells in the market. These, too, are easily available.

Safety is the Key

Homemade solar power is a non harmful device that is generous to our environment. It reduces the noise, and pollution emitted by the regular energy supplied by big electrical companies. It makes use of resources that are environmentally friendly, therefore it is safe.

Advantages to be Enjoyed

The wonder of this homemade solar power is that it helps you save up to 80% of the electricity consumption without having to sacrifice the constant flow of the energy being used. Likewise, if you live in a distant or a remote location wherein electricity is scarce, then this is a very promising solution to your problem. After all, who doesnt want to have an uninterrupted flow of electricity?

Can You Live Without It?

Now there can be a wide array of devices that can use this homemade solar power. It can range from small solar power devices such as calculators, chargers, heaters, electric fans, and watches, up to big scale objects, such as solar powered cars and houses.

Accessibility ” How About It?

When the sun is at its sunniest, that is when the homemade solar power works its best. You can also stock up the energy with the use of different battery packs for nighttime use or for other emergency purposes.

With homemade solar power, life promises to become easier and improved. Not only does it provide us with all the benefits for our individual electricity needs, but also it extends to the good of the community. Homemade solar power gives back to mother nature as it is a harmless device to our environment. With all the promising benefits it holds for mankind, homemade solar power will be one of the best inventions man has to gain.

How To Use Solar Panels At Home

The sun’s energy can be turned into more directly useful energy with solar panels. These devices gather the sun’s rays as they fall on the panels. This powers other mechanisms that can transform the heat and light into any form of power that you require.

We could use solar panels to convert the heat from the sun into the energy we need to power things that run. Solar panels are common and can be seen in a lot of different products, such as calculators, satellites, or even space ships.

You can efficiently turn sunlight into electricity and other useful power with solar panels. These panels have existed for more than a century, since an inventor first discovered that the sun’s heat could be used to operate machines.

The main idea was using the steam produced by sunlight to start machinery and to keep it operating. The successes that came about in this way interested other scientists, who wanted to learn everything they could about this system, how it worked, and how it could be improved.

Since then, there have been groundbreaking products that have increased the convenience and the need to use a natural resource such as the sun in order to work machinery. Solar panels can be different shapes and sizes but their main purpose is to convert the light in order to make electricity.

Photovoltaic cells are self generating and consist of a very thing film made of silver. This film is placed on a sPhotovoltaic, or PV, is the process of converting the light into electricity. emiconductor layer that can be found on an iron substrate.

You need photovoltaic cells to get a large amount of heat from sunlight. This heat can be turned into electricity to warm water and keep homes warm. There are round, square, and rectangular solar panels, and they can be made into many other customized shapes if you need them.

It is easy to find solar panels, which are on top of structures, and in meadows. They are also in small personal devices and low energy using appliances. The sun is a tremendous contributor to our lives.

The study of natural resources like the sun is ongoing and the improvement that can be made in the future is anyone’s guess but you can’t go wrong when you use natural resources. Because this new way of production was in trial and error stage, it was somewhat expensive to turn your home or business into a natural way to heat and power.

With the advent of technology and advances in materials and production, the cost and prohibitions in installation of solar panels to generate energy has been substantially reduced although still somewhat greater than traditional sources such as oil, gas and electric.

In the long run using solar panels for all your electric needs will save you money in the long run because you won’t have to worry about paying for your power. As long as the sun shines you will have power.

On days that are too cloudy for the sun to break through to the earth, your system should still be adequate enough to carry the electricity through another day.

Solar Energy

Few people realize the staggering amount of energy the sun radiates. This energy reaches us in the form of heat and daylight, which we utilize for various purposes. But solar energy can be used for so many other different purposes using the right technology.

Through the use of solar technology the energy of the sun can be turned into other useful forms of energy to power many of our modern needs. In our energy dependent society this underutilized resource can provide so much of what we need if only we harness its potential.

Solar panels, or photovoltaic cells, that absorb sunlight and convert it to electricity are one good example of this technology. This electricity can be used in countless ways: it can be used in households, to power houses and solar powered water heaters, it can be used commercially: to power offices and factories. It can even be used on the road: there a many types of devices that offer portable solar battery chargers.

There are other ways to benefit from the sun’s energy. Passive solar is a concept used in designing buildings in a very specific way. In these types of buildings, the sun’s rays are actually harnessed for heating purposes during winter time. This smart design can significantly reduce heating costs.

But the advantages of solar energy do not end here. Solar energy, unlike other sources of energy – such as fossil fuels – can provide clean, safe, and virtually endless amounts of power. Solar energy does not create any air pollution, nor does it create hazardous waste – this alone is worth switching to solar energy. Furthermore, as long as the sun continues shining on us, we are guaranteed that this source of energy will be around – no one can make this claim for fossil fuels, which, as everybody knows, we will eventually run out.

It is easy to see that whether solar power is used to heat water for household use, to generate electricity, or even to power an automobile it is a valuable option to supplement or replace our current technology and to protect the earths valuable resources. Over the long term the cost of solar energy both to the planet and to the pocketbook are much less. As more solar installations utilize solar power begins to gain more acceptance and enthusiasm. This spurs on further development to make the solar technology that is available better and better.
