Here are some additional advantages and disadvantages of solar power. You can change and customize your solar panels and battery device to collect any amount of energy you wish up to the threshold. After the threshold, or when the battery device is full, the solar energy is just being reflected from the solar panels. The battery should be compatible with the device you want to use it for. How many times have you been out fishing or camping and your mobile battery device goes out? Most people carry mobile adapters for their motorcars so that they may recharge the battery device in their automobile. This is fine if the engine is on or the engine has been used to charge the battery device in the vehicle. But running the engine is a cause of pollutants and other toxic materials which you are releasing out into the environment just by charging up your mobile.

By having a mobile solar powered battery charger, you are able to take your mobile outside and leave the solar photovoltaic cells out in the direct sun. You can even do this inside on a windowsill that is directly influenced by the direct sun. You don’t have to worry about where to plug in your charger, you just have to worry about where the direct sun is and how long the solar panel needs to stay out to charge a battery device. It is convenient and easy-to-use, notwithstanding the fact that it is a little expensive.

As industrial science advances and the demand for solar powered contraptions increases, prices should go down and the industrial science should be accelerated. Right now only 1% of all buildings in the USA are powered by solar energy. If we think outside the box and go beyond the home there is an entire world of tools that can be powered by the sun. All it takes is a little imagination and a little investigation and someday soon we will be out of the grips of fossil fuels and nonrenewable energy. There are plenty of advantages and disadvantages of solar power but the advantages are far out weighing the disadvantages and as industrial science moves forward, this gap will only get bigger.

One alternative is to create or build homemade solar panels or wind turbine, so how to make a solar panel may be indeed a great alternative

For some homeowners, building a solar panel or a windmill turbine may look a very overwhelming task, but thanks to these new guides now creating a solar panel or a windmill turbine can be a very simple task.

Most of the manuals lead you step by step until your solar panel or wind turbine is up and running, and the best thing is that you will be able to find all the parts that you would ever need in your local hardware store

You do not need to be an electronic engineer to accomplish this task and learn to how to make a solar panel. Any person with basic knowledge with regular home tools should be able to build their own renewable energy generator and get it up and ready to produce green electricity in no time.

If you are interested in taking advantage of the free and clean energy that comes from the sun and wind, then you really may want to think hard about adding those panels or turbine to your home. Making your own solar panels is not that hard and is truly much cheaper than purchasing them of the shelves.

You will see that once you have a good guide and all of your materials, you are ready to get started. You will find that you are able to how to make a solar panel for around $150 to $200 and in some cases for even a lesser amount depending in the sizes of the panels.

You may find some free sites that offer tips and free information on how to build your own green energy, but believe me, the free information is not nearly as sound as the information that you will find in a good reliable guide created for real experts.

All guides are different, and as it is vitally important that the construction of your system is sound and reliable it is very important that you pick the right guide. Many of these manuals really complicate what can be a very simple task, so make sure that you pick the right set of manuals when you decide to download a guide. We know this from our own experience.

Although most people are under the impression that the field of photovoltaics is a new subject, based on recent invention, this is not actually the case. But first of all lets take a look at what “photovoltaic” means.

The word “photovoltaics” can be split up in to two parts: “photo” and “voltaic”. The term “photo” is derived from the Greek word “phos” which means “light.” A “volt” is a measurement unit for electrical force. So, literally, “photovoltaic” means “electricity through light.” And that is exactly what the word means: “capturing solar energy in the form of light and converting it into electricity.”

So how do we convert sunlight into solar energy and electricity?

In order to convert sunlight into electricity you need to use a material called a “semiconductor”.

In simple terms, a semiconductor is a material that acts as an insulator, but is also able to conduct electricity under certain conditions. We employ the characteristics of semiconductors when we convert solar energy (in the form of sunlight) into electricity. It is done as follows:

When a semiconductor (such as silicon) is exposed to light, it releases small amounts of electrical energy. This is due to the process of electrons (bits of electricity) leaving the surface of the semiconductor, in response to being hit by light. We call this the “photoelectric effect.”

Sunlight is made up of “photons”, which are particles of solar energy. Not all photons are the same and not all carry the same amount of energy. A simple explanation for this is that light comes in many colors. Some forms of light are visible to the eye, while some forms are invisible (such as ultraviolet or infrared light). But, regardless of color or visibility, the fact remains that light is still light and the basic particle of light is still a photon.

When a photon hits a photovoltaic cell (also called a “PV cell” for short) one of three things occurs:

1. The photon can be reflected by the photovoltaic cell

2. The photon can be absorbed by the photovoltaic cell

3. Or (believe it or not) the photon can even pass right the photovoltaic cell. Only the photons which are absorbed by the photovoltaic cell are converted into solar energy (in the form of electricity).

When a photon is absorbed by the semiconductor (the material in the photovoltaic cell which produces electricity) the solar energy of the photon is passed to an electron in one of the atoms of the semiconductor. With this additional energy the electron is able to break away from its atom. Thus an electrical current is generated.

This is the simplicity of what occurs in a photoelectric cell, when sunlight is converted into electricity. The electricity so produced can now be power an electrical device.

As you can see, the field of photovoltaics consists of the technology and the principles we use to convert solar energy into a usable form.

- Photovoltaic Systems

Now that we know what a photovoltaic cell is and how it works, lets take this a step further and take a look at what a photovoltaic system is.

A photovoltaic system has consists of the following components:

- A “photovoltaic module”, or “pv module”. This is a group of photovoltaic cells connected together, commonly referred to as a solar panel, though the terms “PV module” and “solar charger” are used to describe it as well.

- One or more batteries to collect and store the solar energy, which was converted into electricity by the PV modules (or solar panels, solar chargers, or whatever you choose to call them).

- A “charge controller”. This an electrical device which prevents the batteries from being ruined through overcharging, and which also prevents electrical current from flowing back out of the battery into the PV module or solar panel.

- “An inverter.” An inverter an electrical device which changes the electricity produced by the PV modules into alternating current. Alternating current is the type of electricity you get from your wall sockets at home. An inverter is only used with PV systems when you want to produce alternating current as your end result. If you run your house on solar energy, the inverter is installed between the batteries and the fuse panel.

A good quality PV system will operate for more than twenty years. The PV module, having no moving parts, has an expected lifetime exceeding thirty years. Most system problems occur due to poor or sloppy installation.

So how much electricity is generated by a photovoltaic system?

The average PV system will generate about 180 kilowatt-hours per square meter, in most areas of the United States.

A PV system rated at 1 kilowatt will produce 1800 kilowatt hours per year.

In case you are not clear on what a “kilowatt-hour” is, this is a way of measuring the amount of electricity produced or consumed.

Let me put it in monetary terms, which might be easier to understand. Many PV panels are guaranteed to last twenty years or more – most even claim to last thirty years. Even if we factor in the natural loss of efficiency in the PV modules over a period of twenty to thirty years, a PV system will generate close to 36,000 Kilowatt-hours in twenty years and 54,000 kilowatt hours over thirty years.

This is the equivalent of $10,000 worth of electricity at current energy prices.

Therefore, though initial installation of a PV system might seem a little costly, in the long run it is far cheaper to run on solar energy.

There are different types and sizes of solar panels (photovoltaic cells) which produce varying amounts of solar power.

1.Wind Energy

For thousands of years man has harnessed the power of the wind, it used to be the only way a ship could get across the oceans. You will have also seen windmills that harnessed to power of the wind to grind grains or to pump water. Nowadays we are harnessing the power of the wind to create a clean source of electricity in all parts of the world. Wind Farms have been appearing all over the countryside, and can produce enough electricity to power thousands of homes. They are surprisingly simple in how they work, the blades of the windmill and connected to an electrical generator through the use of gears and shafts, that mean when the blades turn electricity is created by the generator.

2.Water Power

Water power is another example of renewable energy that has been used for hundreds of years. The earliest machines were waterwheels, which back then, provided power for grain mills and lumber cutting. Hydroelectricity, as it is now called is the same principle but on a larger scale, the power of the water is used to turn turbines to produce electricity. Hydro power produces an impressive 60% of the electricity in Canada today, unfortunately, the United States are nowhere as close.

For the home owner the simplest ways to get started in producing alternative energy is to look at solar power or wind power, there are now a multitude of options available to get started with. Remember you don’t have to start big, as big changes usually come from lots of small ones, so what small change are you going to make today.

where you can learn about solar power and other forms of alternative energy you can use around your home. You can also learn how you can do your bit to stop Global Warmings- Renewable energy enthusiasts

One resolution that’s becoming more trendy is to make it yourself. There are numerous books that claim to teach you how to do this, but how good are they?

Earth4Energy is one of the most popular DIY residential solar power and wind power books available and as it turns out, with good reason.

Earth4Energy promises to teach you how to make your own solar panel or wind generator for under $200 and does precisely that. But we believe the best part to be the instructional videos. Everything is easier when you truly see someone do it.

It also contains a few of what they call “free chapters” that teach you how to lessen your oil dependency and how to use ethanol as a viable energy source.

There is one thing you need to be aware of, though. While it’s feasible to create a solar panel or wind generator for under $200, this isn’t going to replace your utility bill. It will take much more than one wind generator or solar panel to make a major impact on your utility bill.

What we didn’t like: Earth4Energy gives you all it promises, but little else. There are no bonuses and modest insight other than the obvious. But if all you want is to create your own wind generator or solar panels, you can’t go wrong. And as we mentioned earlier, the instructional videos make it rather easy.

If nothing else, if you like to create things, this could be a fun project. Having the ability to power even a small device using only the sun or wind gives you a sense of triumph.

Important notice! Don’t buy Earth4Energy from the main sales link! At the time of this review, we discovered that if you try to leave the page or close “Suzy”, their spokeswoman (which we found a bit annoying), a phony chat box pops up and offers a $10 discount. We highly recommend that if you plan to buy, to take take them up on this offer.

Usually, although they tell you it’s a limited time offer, they never go away. BUT … you never know. If you plan to buy, we suggest taking advantage of this special right away.

Bottom line: if you fancy yourself a handyman or woman and have been thinking about this, Earth4Energy gives you everything you need to know. For product comparisons, visit DIY Residential Solar Power and Windmill Power Reviews for more details.
