Beginners Guide To Solar Power

The function of a solar cell is very simple. It takes light, and it makes it into electricity. It’s very simple, but that doesn’t mean it is easy. Imagine if you were tasked to create something that could actually do that, most people wouldn’t know where to start. Well, by the end of this article, you’re not going to be an expert in how to build solar panels, but you should at least understand the principles involved.

How Does Light Become Electricity?

To answer this question of how it is that light becomes electricity, we have to be more clear about exactly what light is and what electricity is. There isn’t room to go into detail about this of course, but we can get a general idea.

A Photon

The most important thing to know about light when it comes to solar panels is that it can be viewed in two ways, as being made up of waves and as being made up of particles. In fact both is true, which is a bit strange, but this is something that has come out of quantum physics.

In terms of solar cells, the most useful way to think about light is as being made up of particles of light. That is what a photon is, it is the name for a particle of light. If you’re wondering how light can be thought of as being particle based, in terms of waves it is the smallest packet of waves that you can get (if that makes it any clearer!).

What Is Electricity?

Electricity consists of the uniform flow of electrons in a substance. The substance has to have certain qualities which allows this to happen, they have to be made up in a particular way. When the conditions are right, then we call that material conductive, because it can conduct electricity. This applies to metals mostly.

There is another type of material though which conducts electricity in a slightly different way. It still has to do with the electrons flowing, but this flow can be created by the existence of “holes” in which there should be an electron. This hole will attract an electron, so that is how electricity can flow as well. Substances that do this are called semiconductors.

Solar Cells

With this information, the way that a solar panel actually works can be described more easily. The first thing to know is that they are made of a semi-conductive substance, often silicone. The important thing about this is that when a photon hits the semiconductor which the cell is made of, it pushes an electron out of its orbit and this creates a “hole” in it, like the ones described above. This is what causes electricity to flow.

It’s not quite as simple as getting a semiconductor and hooking it up to some wires though. There are actually two halves, one of which has to be negatively charged and the other half has to be positively charged. In their normal state, these halves are balanced, but when light hits them the balance is upset and that is what makes the electrons move in a uniform way.

How The Solar Electricity Is Made Useful For Your House

A little bit more work has to be done before the electricity can be used in a house though. It comes out as direct current (DC) but houses run on alternating current (AC) so it has to be converted before it can actually be useful.

On the way to the converter, however, it makes a stop in a battery. This is a DC battery, and that’s where the electrical energy from the solar cells are stored, so that it can be used when needed.

Why Get Solar Power For Your Home?

When considering getting solar panels, there are probably going to be two factors that concern you. Those are, what the environmental benefits are going to be, and whether you can afford it or not. Or it might be whether it’s a good investment or not, and not whether there are any advantages for the environment. Usually it will be some combination of the financial and the environmental factors though.

Financial Advantages

At the present time, energy costs are rising pretty consistently. This means that it is costing more for you to power and heat you home. Wouldn’t it be great if you could have something that would generate energy for free? Well you can with solar power.

Well, it is going to be free after you pay for the installation, so it is not entirely free. Once you are using the energy though, you will actually be saving money because you won’t have to get nearly so much energy from your normal supplier.

What is going to quicken the process of paying off your installation costs is the feed in tariff. This is a government scheme which was introduced in 2010 that gives you money for all of the renewable energy produced on your premises.

How much money each installation will generate will come down to a variety of factors, one of the main ones being how many solar panels you get installed. The average amount that is made every year, however, comes to about one thousand pounds, so it won’t take very long for you to pay off the installation costs.

Environmental Advantages

The reason that most people are interested in getting solar panels though is not for the money that they are going to make, although it is a sound investment now. Instead, they are interested in helping the planet by reducing the amount of fossil fuels that are burned.

At the moment there is relatively little energy that is produced around the world from renewable energy sources, but the small amount that is will still be making a difference. After all the energy that is produced in that way is energy that does not have to be produced by burning coal, oil or some other fossil fuel.

The problem with using fossil fuels of course is that they let off carbon dioxide when they are burned. And carbon dioxide, as everyone knows by now, is what is said to be the driving factor behind the global warming that we have been seeing. Everything we can do to prevent more energy being made in this way is therefore going to be helpful.

Even though it might not seem that one more home getting a solar panel installation is going to matter very much, it all makes a difference. Once enough people are using renewable energy there will be a significant reduction in the amount of carbon dioxide that we are producing every year.

Is It Worth Getting A Solar Installation?

With each new solar installation only making a minor difference, and with the cost being in the region of several thousand pounds, you have to ask whether it is worth it. That is a difficult question to answer, but if the initial outlay is affordable then you can be sure of making your money back. Also, though small, the environmental benefits will accumulate.

This is not the sort of decision that you should make lightly though of course, and it’s best to get expert advice. So you should find out exactly how much it is going to cost, and how long you can expect it to take before you make your money back.

There’s certainly a lot more to discover about solar panels, which you are able to do at Solar Energy UK the place where Brayden Morgans enjoys writing. This is in addition the best location to get the cheapest air source heat pumps for your home.

Solar Panels For Residences

It is one of the most versatile and popular forms of renewable energy, but why are solar panels so much in demand? There are actually two reasons, one is that they can make a significant difference to the environment, and the other is that they are financially viable for many people. You have to be careful when you talk about them though, because there are actually two types, one that generates electricity, and another which heats water.

Photo Voltaic Cells

If you want to cut down on your electric bills at the same time as reducing your carbon footprint, then having PV cells installed on your roof is a great way of doing that. Even in the UK where, let’s be honest, it is not always sunny, they will work throughout the year. They work when there is cloud cover, and in any light conditions except for darkness. Although they do work better the sunnier it is.

Of course for this to be practical it has to be affordable. There aren’t national solar grants available any more, so you will most likely have to pay the full price for the solar installation. However you can now get financial assistance once you have the panels and they are generating electricity. This assistance comes from the government in the form of the feed in tariff.

The government has incentivised solar energy by paying you for the energy you produce in that way. It’s as simple as that really. You will have a metre installed at the same time as the solar cells, and that will monitor the energy you are producing. And for every kWh you will receive about 40p. When you consider that the panels will be generating electricity all the way during the light part of the day, that actually adds up to a lot over the course of the life of the panels. For a standard installation, about 25,000 in fact.

Solar Thermal

One of the main ways that we use energy in the home is for heating. Whether it’s for the hot water we need, or for central heating, this takes up a lot of energy. Another good way to cut down on the costs of all that then is by using renewable energy to heat your home, and one of the ways to do that is with a solar thermal system.

It might sound odd at first, but solar thermal panels work in much the same way as PV cells in that they do not get their energy from the heat of the sun, but rather from the light. The reason they are designed that way though is because you don’t lose out on any of the extra heating effects when it is actually hot and sunny, but at the same time it will still work on cloudy, miserable, rainy days.

Other Renewable Sources

Although it is one of the most popular sources, due to its versatility, solar energy is not the only renewable source that is available to homes. You can even get a mini wind turbine, although there are few properties which actually lend themselves to that technology. In terms of renewable heat though, there are viable alternatives in the form of air source and ground source heat pumps. They get the latent heat which is always present either in the air or the ground, and use that to heat your home.

The reason that all of this is important, of course, is because of the environmentally damaging effects of fossil fuels. We also have to remember that they will run out one day, and that might be sooner than any of us realise. With energy prices rising all the time though, and the effects of global warming accelerating, there has never been a more important time to consider solar panels or other renewable sources of energy.

5 Excellent Reasons To Install Solar Panels

There are plenty of good reasons to have solar panels installed on your roof, both financial and environmental ones. This article will be going over five of them. If you do decide that you would like to get solar cells for any reason, there are plenty of companies out there, for example http://www.solar-energy.co.uk.

1. Global Warming

It is difficult to say precisely what the effects of global warming will be, however they are unlikely to be good. One idea is that it could affect planetary ecosystems, and this could lead to our food production depleting. Also, everyone has heard about the sea level rises which could threaten to wipe out coastal areas.

The crucial factor in stopping global warming from advancing is by stopping burning fossil fuels. Unfortunately we cannot just stop altogether and all at once because we rely on that energy for so many things, not least our food production. What we do need to do then, as soon as possible, is start using more renewable energy. And everyone can help with that by having solar panels installed.

2. Pollution Effects

Some people think that global warming is caused by pollution. It is difficult to refer to carbon dioxide as pollution, however, because it is a necessary substance in the atmosphere. The problem is simply that there is too much of it.

However pollution is another problem that is caused by burning fossil fuels, and which will be reduced by using more renewable energy. The way that pollution is a problem is that it affects the local environment in which the fossil fuels are burned.

3. Personal Financial Benefits

Most people who are interested in renewable energy are most interested in the positive environmental effects that using it will have. However, while most people would like to be able to help, if they cannot afford a solar installation then they simply are unable to. A recent scheme by the government, the feed in tariff, which makes solar panels a better investment is therefore very welcome.

The feed in tariff does not actually help with the initial cost of the investment, what it does do however is make it so that these costs can be paid off sooner. After that there will also be time to make profits from the energy produced. And that is on top of the savings that you will be making by not needing so much electricity from your normal supplier.

4. Economy

Although it makes some difference when a few individuals use renewable energy, the effect is quite minimal. For it to have a long lasting effect, the whole economy is going to have to run off renewable energy. So the more that is produced in that way, the closer we will be to achieving that.

It is also good to consider the economics of it. When people purchase renewable energy they are indicating a demand for it, and so companies supplying it are going to grow. The more solar panels they produce, the larger the supply, and the lower the cost. That, again, should increase demand, and in this way more and more people will be able to use it.

5. Increasing Costs Of Conventional Energy

The more conventional energy rises in cost, as it is doing, the more attractive it will become for renewable energy sources to be used instead. This is going to motivate even the people who are not concerned about the environment to use renewable energy, so this is a positive factor as well.

The earlier you get in with renewable energy, the more advantage you are going to get with the savings from conventional energy. You don’t want to wait until it is so expensive you can barely afford it though because that is going to make it more difficult to afford a solar installation.

Should You Get A Solar Installation?

If you choose to get a solar installation, you will be able to take advantage of all of the points listed above, some of them financial and some of them environmental.

How Solar Energy Combats Solar Energy

It is now almost a daily occurrence that we hear about how global warming is getting worse, and the disastrous effects that it will have eventually. It’s hard not to get depressed by it all because it feels as if there is nothing that you are able to do about it. Actually though, lots of people are in a position to take a stand, only they might not know it. All they have to do is get involved with solar energy and they can make a difference.

Solar Power For Houses

The way that people can help in the fight against global warming is by using solar panels on their roofs. It’s not going to make a big difference, one house isn’t anyway, but if lots of people do it then it will make a big difference. It is possible for solar cells to power everything in our houses.

How solar cells are able to convert light into electricity is an interesting topic in itself, but it is beyond the scope of this paper. In terms of global warming, the important thing to realise is that when you use solar power you’re not only helping by getting your energy from a clean source, but you are reducing the demand for energy from the polluting sources which are creating the whole problem.

How Does Global Warming Work?

Anyone who is interested will already have been able to read up on how it is that global warming operates. For anyone new to the subject or who needs a quick refresher, it is quite simple though. When fossil fuels are burned the let off carbon dioxide, which is a greenhouse gas. The significance of it being a greenhouse gas is that it helps to warm the Earth by trapping the heat from the Sun in the atmosphere.

Of course the reason that we do this, and continue to do it despite the potential consequences, is that this is what allows the global economy we have now to function. We need all that energy, and even more each year as the population increases, in order to survive. We would literally not have the means to grow the food we need to survive without it.

This poses a big problem of course, because without the economy running we would starve, but by using fossil fuels to keep it going that could be the result anyway. The solution should be quite clear then, we need to find another way to generate the energy we need, which is not going to cause warming. The good news is that we already have that in the form of renewable energy, of which there are many different forms. The bad news is that these are not, as yet, economically viable. But the situation is getting a bit better on that front.

Can You Afford Solar Panels?

Until renewable energy becomes economically viable it will not be able to take over from fossil fuels. As energy prices keep increasing though, it is becoming a better financial option to use renewable sources instead. The government has been able to help this process along though, and they have done this by providing financial assistance for people who do choose to make use of solar installations.

There is a certain amount of money that using solar energy saves you automatically, because you don’t have to use so much electricity from your normal supplier. However that alone would only allow you to pay off the cost of the installation after about 25 years. Now though it only takes 8 years, and after that you are actually making money from the technology. That’s because with the feed in tariff, you are paid for the energy produced by your panels. There is a way, therefore, for many more people to realistically help counter global warming effects.

How Good Is Solar Energy In The UK?

With the UK not having a particularly warm or sunny climate, how much use can you get out of solar energy? That is what this article is going to explore. We’ll look at how solar cells work, what the environmental and financial benefits are, and so whether solar energy uk production is actually worth it.

How Solar Panels Work

With the UK being under cloud cover for much of the time, how much usage are you going to be able to get out of solar panels? The answer is a lot, because they do still work whether it is cloudy or not. That is not to say, however, that they do not work better, creating more electricity, when it is hot and sunny, but they do work. The reason for this is that they rely on light, not heat, to create electricity.

It is actually very complicated how this works, so this will only be a very brief overview. It comes down to the fact that they are made of light sensitive semi-conductive materials though. What this means is that when a photon (a particle of light) hits a solar cell it frees an electron. The flow of electrons is what electricity is, so solar cells can be set up in such a way that this creates a current of electricity.

The more energy the electrons are hit with though, the more electricity is created. So the more energy is in the light, the brighter it appears, the more energy the electrons will get. So they certainly do perform to a higher standard in warmer climates, but they will work just about anywhere.

The Environmental Benefits

On a global level solar energy is very important because of the effects that it has on the environments. Actually it would be more accurate to say that it is important because of the lack of effects it has. The normal sorts of energy that we use do have effects, we generally have to burn something and this can cause pollution and it usually means that carbon dioxide is being released into the atmosphere as well. This is the way that man-made global warming is created.

In terms of the environment, the main benefit they have is that they are clean. That’s why, strictly speaking, they don’t have any positive or negative effects on the environment. At least in isolation they do not, but when you consider that we have to get our energy from either clean or polluting sources, the more we get from clean sources the less we need polluting forms of energy. So that’s the way solar energy benefits the environment.

What Are The Economic Benefits?

It is an undeniable fact that one day non-renewable energy will run out. Even before that happens though, it will be too expensive to extract from the ground, meaning more energy will be needed to get it out than it will provide. When that happens, if we’re not already getting our energy from renewable sources the economy will collapse. We simply won’t have the energy for it to keep going. That’s the future benefits to the economy of solar energy.

On an individual level though, the benefits can be felt right now. These come in the form of savings, because you are not going to have to pay so much on energy bills when you are using solar energy. It also comes in the form of the feed in tariff though, which actually pays you money for the energy created. The reason this scheme is in place is to encourage people to use more solar energy so that we can get the aforementioned environmental benefits.

Getting Involved With Solar Energy

Although solar energy has its disadvantages, they are vastly outweighed by its advantages. At least, they should be. It is relatively efficient, compared to other renewable energy, and it is certainly relatively cheap compared with them. Also, individuals are able to get solar power for their own property.

Two factors are going to come into play when you are considering having this done. The major one in terms of practicality is going to be the issue of cost, can you afford it? Of course in that equation you have to take into account the savings you will be making in later years, not just the installation. The reason that you are probably going to be particularly interested in renewable energy, rather than some other financial investment, is the environmental benefits which using it accrues however.

Although the financial issue is more important in each individual practical case, the environmental concerns are potentially even more important if the worst case scenarios of not transitioning to renewable energy come to pass. If we cannot eventually transition to renewable energy then one of the following scenarios is virtually certain to occur. Firstly, we could run out of the fossil fuels, in fact as they are non-renewable sources that is certain to occur unless we choose to stop using them first. This will mean that we won’t be able to use electricity anymore, we won’t be able to use mechanical transportation, in short it will be a return to the dark ages. Before that occurs, however, we might get the effects of global warming, which could lead to such a shift in the climate that humans will no longer be able to survive on this planet.

When considering these scenarios, it might seem as if the financial aspect is going to be a distant second in terms of importance. However it is only when the technology is financially viable that people will, on a large scale, be able to use it. If we are able to create solar power as cheaply as we can get energy from oil, that will be the time when the transition will actually be made, so that is why the financial angle is actually just as important.

At the moment, however, there are many challenges to be faced in terms of the solar power that we are using. First of all, it is not very efficient. That means that for all the energy that the solar panels could potentially be getting from the sun, much of it is being wasted. That is why research is always being done in to how to make solar cells more efficient.

As already stated, the issue of how expensive solar installations are is also an important one. Although the government cannot really just give people free solar panels, they are doing what they can to make buying them a better investment, and therefore more attractive to people. Although this does not solve the problem that many people still will not be able to afford the installation costs in order to take advantage of the Feed in Tariff scheme.

If we were only able to power our homes with solar power, however, then it would only solve half the problem. There would still be the issue of all of the energy we use for transport. However we are able to put solar panels anywhere, even on cars, boats and planes. Eventually, therefore, just about everything could be powered by the sun.

The key questions now are whether the technological advancements in solar energy are going to come quickly enough to prevent global warming and economic collapse. Also, are people going to recognise the magnitude of the problems that are being faced and act accordingly by using renewable energy themselves? We are just going to have to wait and see what happens.

Solar Energy Advantages

If someone told you that the future of the human race depended on our using more solar energy, you might think that they were crazy. If that were the case, then surely the politicians would be making more fuss about it, surely there would not be objections on aesthetic ground to sites being created, not if it is so important. However, through applying a little bit of logic, we can see that it is actually that important.

The reason that solar power, and indeed all forms of renewable energy, are so important is because of the drawbacks of the alternatives. At the moment most of the energy that we produce comes from fossil fuels. These are fossil fuels which pollute the atmosphere and which, one day, will run out. Actually though we will have problems before they run out, the way that the economy is able to run is that it has got access to cheap energy. As soon as we start running out of conventional energy sources then, it is going to become more expensive and the economy could completely collapse, leading to chaos.

The only way that we can avoid the problems caused by using non-renewable energy is by transitioning quickly to renewable energy. At the moment the most popular and widely used of this kind of energy of is solar power. This comes in the form of solar panels.

The way that solar panels are constructed is that they are formed of a collection of solar cells. To form a lot of energy, you can put the PV panels together as well, and make a solar farm. Or they can make solar cells which are actually extremely small, and they can be put in pocket devices, like calculators. The way that individuals can most effectively get involved, however, is by getting the ones that go on the roof of your house, so that you can power your home.

This is where a true sort of democracy, of power in the hands of the people, comes into play. There is no need to plead with the government to build solar power plants, or to encourage corporations to do so, all you have to do is buy solar panels for your own home. When enough people do that, our energy problems will be all but over.

The reason that everyone has not already had a solar installation, however, is the expense. To have solar panels installed on your roof is quite expensive. That’s why the government has introduced a scheme whereby you actually get money paid to you for the energy you produce with your solar cells. Not only will you be making the savings on your electricity bill then, you’ll also be making extra money. This makes them more profitable, and a more viable financial investment.

When we are talking about something as serious as the human race being wiped out potentially, considering financial matters might seem rather crude and inappropriate. However people cannot afford to ignore their finances, because that is what allows us to survive today. And of course if we did not survive today, then we would no future to speak of in any case.

The best thing about solar energy is probably that you have the opportunity to directly get involved in using it. You can stop being a part of the problem, reduce your carbon footprint, and make money at the same time when you get solar panels for your property.

David Brown writes at Solar Energy UK, where you can get more information and have solar panels installed.
