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.

Hydro Energy for the Home
Can I really use hydro energy to power my home? There are really very few people who would be able to take advantage of hydropower in their homes. A small stream simply isn't going to be big enough to power even a micro hydro energy system but if you happen to be one of the very lucky few who have a reasonable size stream or waterway of any sort running through your land then hydro power is an excellent form of power and you should consider looking into it. It has one big advantage over any...

An Introduction to Wind Energy
About wind energy? Put simply, wind energy is energy derived from the wind. By using wind turbines we are able to harness the power of the wind and convert it into electricity for use in homes, schools, businesses and any other establishments that require electricity. Originally it was thought inconceivable that we would be able to use wind turbines for anything other than milling flour but this theory has been proven to be very wrong. Our search for renewable sources of energy has led us...

Wind Energy Systems for the Home
Is it possible to power a home using wind energy? In theory it is possible to become energy self-sufficient relying on purely wind energy to power your home, but in practise the situation is somewhat different. You may find that unless you have a small house, a large patch of land and forgiving neighbors it is very unlikely that you will become self sufficient off the back of wind energy alone. Most houses would take up to a dozen wind turbines to power their house but by combining wind...

About solar energy panels
What is a solar energy panel? A solar energy panel collects energy from the sunlight and converts it into direct current (DC) electricity. Two oppositely charged slices of silicon are placed together below a piece of glass and as the protons in the sunlight knock the negatively charged neutrons away from the silicon the electric field created by the two adjoining pieces of silicon attract the neutron. Small pieces of wire catch the neutrons and when they connect they create direct current...

The Advantages and Disadvantages of Alternative Energy
It is essential that we find affordable and workable sources of alternative energy before the world completely consumes the already limited stock of fossil fuels. Many countries have started to introduce renewable energy schemes and more still have invested money into researching and even producing different sources of alternative energy. While it is essential that we become less reliant or not reliant at all on fossil fuels, many forms of alternative energy have their disadvantages as well...

An Introduction to Hydro Energy
What is hydro energy? Fossil fuel reserves have become seriously depleted but conversely our energy use is increasing year on year, our fossil fuel use is now far from being sustainable. Fossil fuels are also responsible for global warming because of the carbon dioxide that is produced with the use of coal power stations and other fossil fuel power stations. In order to stop a further decline in the environment and to replace non-renewable energy many different alternative power sources are...

An Introduction to Alternative Energy
What are fossil fuels? Essentially there are three fossil fuel sources available to the world but each of them are dwindling. The most abundant is coal; coal is widely used and inexpensively extracted. As such, we have come to rely exceptionally heavily on coal and while there is still quite a large amount of coal left it is estimated that America's remaining coal will sustain the country for the next 200 too 300 years but it is by no means a perfectly clean form of power. The biggest...
