In the photovoltaic process solar cells are used to covert light into electricity. Solar cells are made up of semiconductor materials such as: silicon, gallium, cadmium telluride and copper indium diselenide. One of the most common materials used in solar cells is silicon.

In the case of crystalline silicon solar cells, substantially pure silicon with high crystal quality is needed to make strong usable solar cells. In the outer shell of a silicon atom it comprises of 4 bonding electrons. In order to form a stable electron configuration, in the crystal lattice two electrons of neighbouring atoms from an electron pair bond. By forming a stable bond with 4 neighbouring electrons silicon achieves its noble gas configuration with 8 out electrons. This electron bond can be broken by light or heat, which enables the electron to move freely and as a result it leaves a hole in the crystal lattice. This is known as intrinsic conductivity.

Intrinsic conductivity cannot be used to produce electricity. The silicon can only produce electricity when impurities (known as doping atoms) are introduced into the crystal lattice. These atoms have one electron more (phosphorous) or one electron less (boron) than silicon in their outer shell. The phosphorous doping method is known as negative doping (n-doping) and the boron doping method is known as positive doping (p-doping).

In the case of n-doping the electron can move about freely in the crystal and as a result can transport electrical charge. On the other hand p-doping has a missing bonding electron for every bonding born atom in the crystal lattice. This enables electrons from silicon atoms to fill the hole caused by the missing bonding electron, creating a new hole elsewhere. The conduction method based on these doping atoms is known impurity conduction.

If both the p and n-doped semiconductor layers are brought together a p-n junction is made. This junction allows surplus electrons from the n-semiconductor to diffuse into the p-semiconductor layer, thus creating an area known as the space charge region. Positively charged doping atoms remain in the n-region of the transition and negatively charged doping atoms remain in the p-region of the transition. An electrical field is then created that is opposed to the movement of the charge carriers, with the result that diffusion does not continue indefinitely. This p-n semiconductor is what is known as a solar cell. Once the solar cell is exposed to light photons are absorbed by the electrons. This contribution of energy breaks electron bonds. The released electrons are pulled through the electrical field into the n-region. The holes that are formed migrate in the opposite direction, into the p-region. This process is what is known as the photovoltaic effect – turning light into electricity.

Thanks to our fuel consumption, energy resources have become rare and expensive. While alternate energy sources are available in plenty, all we have to do is find ways of harnessing them effectively. Sun is present everywhere, and hence, Solar Power is there for taking. By understanding what is involved in making your own Solar Power Generator, it becomes easy to get free power.

Its first necessary to understand how our homes are powered now. The power supply that comes through the grid is the primary source of power. Its AC – Alternating Current – and the appliances that we use are also built to work with AC. Hence, it is required to produce AC power through the Solar Power Generator that we build.

The primary component of Solar Power Generator is the Solar Panel, which is nothing but an array of Solar Cells. These Solar Cells are the building blocks of the system that would help us get free power. The Solar Panels can be bought or assembled. I’d recommend assembling one, as it turns out to be much cheaper than buying one.

It is important to note that the output of Solar Cells is DC – Direct current. Remember, our appliances work with AC. Hence, this DC needs to be converted to AC to power them. An inverter is used for this purpose. The Solar Panel’s DC output is converted by the inverter into AC and this can be then passed on to the grid or to the appliances directly.

One question that you probably have is – What if there is not sunlight around? What about nights and cloudy days? – A battery helps resolve this. A battery can be used to store the DC from Solar Panels during day time. This battery can serve the DC load to the inverter during the night times or other times when there is no Sun. This way, we can ensure uninterrupted supply to get free power to our home.

So, to summarize, one needs to:

1. Buy/Assemble Solar Panel

2. Give Solar Panel’s output DC load to battery

3. Connect the battery to an inverter

4. Connect the inverter to the grid or the appliances directly

This can be a fun DIY project to do – At least I had fun doing this. I built my own Solar Power Generator from scratch and I have shared my experience of how it helped me get free power with you. Get started with building one of your own by clicking here. Happy building!

In this article we are going to outline 5 main steps you can follow to learn how to build homemade solar panels and with a little work on your part you can be enjoying free solar power for years to come:

1. Buy a guide – Building solar panels is not rocket science but you will definitely benefit from having a pictorial book to guide you each step of the way. There are many eBooks available on the Internet that will enable even the most hopeless at DIY to build their own solar power plant on a budget.

2. Build your solar panels – Solar panels are made up of solar cells connected together in series to form the panel array. The easiest but most pricey option for this is to simply buy premade solar panels. Another option would be to build your own from scratch using sheets of copper but this can be challenging. Perhaps the best way to get started would be to buy defective or chipped panels at a massive discount and learn how to recondition them.

3. Place your panels – You want to place your solar panels to receive optimum amounts of daily sunshine. The roof of your house or an open space in your garden would both be effective choices.

4. Connect the panels to a battery – On lovely summer days you may find your solar panels will generate more electricity than you require on that day to run your house. Connecting them to a battery via a charge controller will enable you to store the electricity for use on more gloomy days.

5. Connect the network to your breaker panel – Your house appliance run on alternating current so you will need to pass the wires through an inverter to convert DC to AC before connecting it to your home’s electricity breaker system.

These steps provide a basic overview of how to build homemade solar panels. It may seem daunting to those of us who are not electrical engineers. My advice would be to check out one of the many eBooks available and see if you can follow the more detailed step-by-step instructions.

Solar batteries are very convenient things.  They are great sources of power when electricity is not available. For this reason hikers and trekkers often use solar batteries and chargers to charge their torches and other appliances. There are available batteries for even charging dead car batteries. Though it takes a lot of time to charge a car battery using a solar charger this is an invaluable option in remote places where it is difficult to find resources and even other cars to jump the batteries.

Here is some information on solar batteries. Solar batteries work on the basic principle that when electromagnetic rays from the sun hit certain substances thy emit ions which are used as sources of electricity. These substances are usually silicon semiconductors which absorb some of the radiation from the sun. While doing this they release some electrons and this flow of electrons is an electric current. A photovoltaic cell which is another name for a solar battery does not carry pure silicon though but also boron and phosphorous put in on purpose to increase the output of electricity.

Solar batteries take a lot of time to charge and do not get charged unless there is some sun. But still they are useful in saving electricity bills. They are also one of the best green appliances invented as by saving electricity they help to save the earth’s resources and cut down on pollution.

Solar batteries can be used on a lot of electrical device like cell phones, mp3 players and laptops. Solar batteries are also used to power garden lights and street lights.

Every year the electric bill always seems to increase in price as we continue too use the same amount of electricity, so it seems. These new computers and plasma TV’s eat up a lot of juice and are not the same as the old tube style television sets of yesteryear. Whatever the case perhaps your looking to reduce your electricity bill each month or just go full out environmentally friendly and live off grid. Solar is the way to go. Look at California, Arizona, and Florida. These are just a few states with plentiful sunshine and a great solar source to power your home all year round.

However converting your standard home to a solar home can be expensive. But what options are there to see if solar is actually for you? Buying used solar panels and equipment will definitely take the edge off your wallet. The main part you need is the photovoltaic cells and if your handy you can just build the panel itself. If the PV cells are in good shape then all is good. Look out for damage and don’t nitpick how it looks, test it with a meter to make sure it still can provide at least 80% power. Think of the PV cells as a picture and the panel as a frame, just frame your picture and that’s pretty much it. Go to your local hardware store for the framing and glass then go to the electronics store to find your diodes and connectors and such.

You may need a guide on how to connect the used solar panels but they are easy to find and simple to follow. Once you have this done the testing can commence. Will there be sufficient hot water at all times of the day if you go solar? The amazing thing will be that solar energy works very well and provides a lot of electricity to power your pool, home, and everything else all summer long. But what happens when it rains or is cloudy for 3 months like in the northeast regions? Just to let you know solar can be stored but not for long, so your home may become a hybrid until technology catches up.

Photovoltaic cells have been used for solar powered calculators for years. Even before that, they were used in space. Now they are being used in many ways, including powering houses. The way photovoltaic cells work is interesting.

The photovoltaic cells themselves are made out of a special kind of material called a semiconductor. Silicon is most often used. When light strikes this substance, the semiconductor takes in some of the energy.

The incoming energy is enough to push some electrons loose. These free-floating electrons flow in the same direction in the semiconductor. This produces an electrical current. The next step is to use contacts that have been placed on the photovoltaic cells and run a circuit from the top contacts, through the item to be powered, and back to the bottom contacts.

The silicon is, surprisingly, impure. This is because silicon in its natural crystalline state does not allow for much movement of electrons. Each of the silicon atoms is unstable on its own because there are four places for electrons that can be filled. Yet, every silicon atom is usually locked up with the other silicon atoms by sharing electrons on the outer valance.

In order to make the silicon material more conductive, it is necessary to dope it, or mix in some other substance. To make N-type silicon, phosphorous is used. It has five electrons in its outer ring, so that when it mates up with the silicon atoms surrounding it, there is one free electron for every phosphorous atom.

P-type silicon is made by doping with boron. It has only three electrons in its outer shell. This leaves a hole, which is a place where an electron can jump in, for every atom of boron. The key to using silicon in photovoltaic cells is to use both P-type and N-type silicon.

The two types of silicon are set up side by side. At first, the electrons and holes near the shared border fill in rapidly. Then, equilibrium is reached where the electrons can no longer interact in that way.

An electric field is created separating the two halves. In this field, it is easy for electrons to flow from the P-side to the N-side. Electrons on the N-side cannot make it over to the P-side. This creates a one-way flow of electrons.

Photons are units of energy from the sun. Photons keep the energy flowing by bumping into the atoms of the solar cell and freeing electrons and holes. This perpetuates the movement of electrons from hole to hole and establishes current. The field created at the site of the N-type and P-type silicon junction makes the voltage that completes the power picture.

Using photovoltaic cells to harness the sun’s energy is still fairly new. The cells are being used in more and more applications, both commercial and residential. Photovoltaic cells are fairly easy to understand and they can be used by anyone who can take the time to learn about them. The use of photovoltaic cells puts solar power within reach.

Are you interested in solar cell construction? Do you want to have a residential solar energy system installed in your house, but aren’t certain the way to choose the best company to do this? There are two things you want to do before you choose the right company for installing solar panels for homes. This article is going to tell you what you need to do before deciding what company to use.

The first thing you want to do is to find as many companies as you can which will install residential solar electricity systems. It’s important that you take the time to compare the different companies. This could help you see how each company is different and will help you see what they offer you for your money.

Once you have the companies in mind then you should research and compare. Then narrow your decisions down to three or four companies that you like the most. The next step is to research online to discover what others say about them and the work that they do when installing residential solar electricity systems. If somebody has a bad experience with a company, they will usuallytell someone. So, the best place to look is in forums.

It is also an excellent idea for you to try the company with the BBB. Please ensure that they haven’t had any grumbles against them when they install a solar electricity system. This is extraordinarily crucial because if a company has had complaints against them, then you are generally better off if you can find another company to work with. Reading reviews of different companies helps in this regard.

The last thing you need to do is to contact each company and ask them any questions that you have. Make sure they are willing to talk to you and that they arecredible company that understands the value of their customers. Don’t work with anyone that is not willing to answer your questions that is usually a bad sign.

How easy is it to find build your own solar energy system? Extremely easy. Here’s why.

Making your own solar and wind power for less than $200

Whether it’s solar cells or hot water solar heating, systems can be built a  lot simpler than you probably realise. Take for example the heating of a swimming pool. You can heat it by laying a long (the longer the better) length of hosepipe out in the sun, and slowly running water through it into the pool.

You will be absolutely amazed at the rise in temperature of the water exiting the hosepipe. Depending on the size of your pool, the length of hose and the outside temperature, this can make a tremendous difference to the pool.

Of course, that is about the simplest method imaginable, but extremely effective. The next step up from this method would be to use the pools own pump to circulate the water through the hose. You can use the trial and error method, but the rule of thumb is that more water circulating and heating up less is more efficient than the water circulating much slower but with the time to heat up more.

Making your own solar and wind power for less than $200

For sure, the absolute rule is that the more hose you can use the better. The reason is that there’s more surface area for the suns rays to do it’s work. This is even more important on not so sunny days. With sufficient lengths of hosepiping (solar treated piping is best) even cloudy days will result in substantial temperature increases in the circulating water. This couldn’t be easier.

As for cost…DIY  systems can be built for much less than you can imagine. Take the example above. The cost of a hose pipe will provide a simple system. More substantial, effective solar panels used to create electricity can be made for under $300

It’s very cheap, and very simple to Build Your Own Solar Heating System…but very effective.  Click below on FREE HOME ENERGY  to find out a bit more information.
