How Does Solar Power Work?
The basics of solar power.
Solar power is probably the cleanest, most viable form of renewable energy available and it can be used in several forms to help power your house. Many gardens now use solar lights or solar garden water features. The availability and wide use of solar power in gardens shows exactly how versatile it is as a source of energy. The technology and the systems are becoming smaller, more compact and better looking than when they were first created and used. Early examples of solar power systems can be seen in California where, in the 1980s, enough solar power panels were installed to power over 10 million homes.
How do photovoltaic tiles work?
Simply put photovoltaic tiles and other forms of solar energy work by converting some of the energy in sunlight into a clean form of electricity that can be used in our houses. The PV cells consist of a positive and a negative slice of silicon placed under a thin slice of glass. As the protons of the sunlight beat down onto the PV cell they knock the neutrons off the silicon. The negatively charged free neutrons are attracted to the silicon but are trapped by the magnetic field that is formed from the opposing fields. Small wires on the silicon catch these neutrons and when connected in a circuit an electric current is formed.
This reaction gives Direct Current electricity though, and it must be passed through an inverter to be converted into an Alternating Current used in our homes to power any electrical items. Some of the power is lost in this part of the process as the inverter is only around 95% efficient but this is a much greater efficiency than was once available.
The nature of the PV cell means there is little or no maintenance required and there are no moving parts; this means that a typical PV cell can last up to 40 years with no work besides an annual clean.
How can I use them to power my house?
There are several ways to use solar power around the house and not just for powering. You can use it to heat your hot water, heat your pool or even your central heating or if you have plenty of roof space and a reasonable amount of sun you can get a grid tie system; a grid tie system means that not only can you power your entire house but during those times when you create an excess of electricity you can sell it back to the grid. An efficiently solar powered home will be able to reasonably create between 75 and 100% of their own power and because of the grid tie system this means you may not have to pay for electricity ever again.

Solar Electric Energy Overview
Solar energy electric is created through the use of photovoltaic technology - converting sunlight to electricity. With the use of sun energy, photovoltaic systems are able to power simple electrical equipment such as computers and lights as well as household appliances.
The PV (photovoltaic) process transforms solar energy to solar power. Solar energy is lavish in its availability and is entirely free. A photovoltaic cell is made up of one thin layer of semi-conductor material, especially silicon. Exposure of silicone to light results in the production of electrical charges. Since a single cell generates a small amount of electrical output, several cells are connected to form a panel (also known as a module) by encapsulation. The principle building block of a photovoltaic system is the PV panel or module. Multiple modules can be connected to produce the required electrical output.
Since PV equipment does not come with any movable part, they generally need little or no maintenance. Solar energy electric generation is accomplished with the photovoltaic equipment without the emission of greenhouse as well as other gases. In fact, its entire operation is a silent one. This is why the solar power production is the safest and most noise-free energy around. This is a healthy development to our environment and wildlife, as opposed to other conventional techniques of energy production.
Photovoltaic Systems - What are They Used For?
Solar energy is supplied to many applications using the PV systems. These applications include systems supplying power to remote places far from the grid and systems supplying power to buildings in the city. These systems are equally connected to the conventional solar power network - especially in the United Kingdom. The important thing is that the solar energy produced by the photovoltaic system in the daytime can be consumed instantly or offered for sale to any of the electric power supply companies.
General Benefits of Solar Power
Generally, solar power is very beneficial both to the home user and the business person. It is a good alternative source of electric energy generation. The business owner who installs a solar panel in the office environment will no longer pay huge energy bills; instead, he can even decide to sell unused generated power to any of the electric power companies, thereby generating income from this investment.
The home solar energy user also obtains a similar benefit of saying good-bye to conventional electric power bills. Excess power generated can also be sold. Governments are also granting rebates to those who acquire solar energy panels to encourage more people to use this ideal power generation alternative. At the end of the day, your solar panel will generate funds to pay the cost used in acquiring it, and even leave you with extra income!
Solar energy is in abundance and cannot run in short supplies like the normal fuel or fossil. Besides, its generation process or technique does not pose any harm to humans, wildlife and the entire environment.

The Future of Solar Panel Technology
Solar Panel Technology:
Look at the calculator on your desk. Chances are the sun powers your calculator. Just check for the familiar small, dark gray panels on the front of the calculator. If they are there, your calculator operates with solar panel technology.
How does that little solar cell do its job? It uses photovoltaic cells. Photovoltaic (PV) comes from the words light (photo) and electricity (voltaic). Photovoltaic cells or modules (groups of cells) convert the light of the sun directly into electricity. It may seem exotic to use photovoltaic cells to power a small hand calculator, but solar panel technology is being applied to more every day.
Here's how PV cells turn sunlight into electricity. They are made of materials called semiconductors. A frequently used semiconductor is silicon. When the sun strikes the semiconductor, the silicon soaks up some of the light. This transmits the energy within the sunlight to the semiconductor.
The energy breaks the electrons free, permitting them to flow unrestricted. To make something useful of all these free-floating electrons, the cells use electric or magnetic fields that drive the free electrons to flow like river, creating a current.
By inserting metal contacts at the top and bottom of the PV cell, we can extract the current to power something outside the cell. And there you have the basics to all solar panel technology. The total wattage (or power) is determined by the extracted current added to the cell's voltage.
Advances in solar panel technology may actually see the panel itself disappear. The newest and most promising advance is the dye-sensitized solar cell (DSC) technology. In 1991Michael Gratzel, a chemist at the Swiss Federal Institute of Technology pioneered DSC (also called Gratzel cells).
DSC solar panel technology is designed in layers. A photosensitive layer composed of nano-sized, ultrathin semiconductor crystals over a fine layer of titanium dioxide. When sunlight hits the photosensitive layer, the loose electrons collect on the layer of titanium dioxide and produce an electrical current. A dye made of amorphous organic material covers the titanium dioxide -- the dye absorbs sunlight and attracts free-flowing electrons, which creates a charge.
DSC lends itself to thin layers of photosensitive film. This transparent, lightweight, flexible and low-cost, sheets or dye film can be applied to the windows of your house or car, even to your sunglasses. The film generates a charge that can be applied to a small battery to power anything, including your phone or MP3 device.
The military even has applications for the DCS solar panel technology. The film can be applied to tents to power lights and laptops. In larger applications, it could power entire command centers. It could cover backpacks or be made into wearable solar panels and power a soldier's electrical devices, eliminating the need for bulky and heavy supplies of batteries.

Increase Your Solar Panel Output by Using a Solar Tracker
Solar Tracking System:
So do you want to know how a solar tracker can increase your solar system output?
I understand how a lot of people are using solar systems to power their homes. It saves a lot of money plus it is an environment friendly source of energy.
Well, I do use solar panels myself to generate electricity at my own home. And guess what?
I was able to increase the output of my solar system by using a solar tracker.
Get this- A tracker can increase your annual output by a minimum of 30%.
I want you to think about this- We all know that the position of the sun varies both with the seasons and time of the day as the sun moves across the sky, right?
Of course we all do, even a 10 years old knows that.
Solar tracker
A solar tracker is a device for orienting a day lightning reflector, solar panel or concentrating solar reflector or lens toward the sun.
Solar systems work best when pointed at or near the sun, so a tracker can increase the effectiveness of such systems over any fixed position.
Trackers may be a single axis or a dual axis. A single axis tracker increases the annual output by a minimum of 30%, and a dual axis tracker increases it by an additional 6%.
Trackers are perfect to use with solar panels, to ensure the maximum efficiency of your systems.
Some solar units are sold with trackers, these are usually expensive. However, you can find some inexpensive trackers that are sold alone.
Warning: If you want to save a great deal of money, you can build your own tracker, which is very easy to do.
Increase your solar panel output and use a solar tracker!

Info about Solar Energy
The Solar Energy:
On planet Earth, sunlight is an incredibly important form of energy. Every day, the
sun pours unimaginable amounts of energy into space. Some of it is in the form of infrared and ultraviolet light, but most of it is in the form of visible light. Some of this energy falls on the Earth, where it warms our planet’s surface, drives ocean
currents, rivers, and winds, and is used by plants to make food. Life on Earth depends totally on the sun.
