Solar power is generated when energy is extracted from the suns rays through the use of photovoltaic cells (commonly referred to as solar cells). These cells convert photos (from the suns rays) into electricity, and this process is known as the "photovoltaic effect."

Many people are beginning to invest in such technologies to avoid rising electricity prices and to help our environment. If every home could be fitted with solar panels, then the strain on power stations would decrease dramatically, which means we wouldn't be left as dependable on fossil fuels as we currently are.

There are many alternatives to solar power, so why should we invest our money into solar technologies, rather than lets say, home wind turbines, or a geothermal energy system? To answer this, we shall look at the advantages and disadvantages of the technologies above.

Solar Panels:

Advantages - widely available, relatively easy to install, very significant output, a solar panel will pay for itself in two to three years, lifetime of 20 to 30 years, modern cells can harness power on cloudy days, can bring power to remote locations. Disadvantages - costly to begin with, older technologies won't work too well if cloudy.

Wind Turbines:

Advantages - fairly cheap for a home turbine, can be used in harsh conditions. Disadvantages - totally dependent on the wind, small output, larger turbines can be noisy, wind farms are seen by many as eyesores, larger (more effective) turbines can be very expensive.

Geothermal Energy:

Advantages - can aid in the heating of hot water, save money on running your boiler, can supply effective underfloor heating, heat from the ground can be relied upon. Disadvantages - have to lay hundreds of meters of piping underground, hard to fix a leak, expensive, longer time to heat water than a boiler.

So there we have the advantages and disadvantages of each. Assuming you do not live by a rapid stream or running river (which rules out hydroelectric power), then as you can see from the above text, solar power is your best option. Solar panels offer many more friendly factors and less disadvantages than other technologies.

A proven method is to have more than one of the above technologies installed around a home (all three would be a dream, but also leave a large hole in your wallet). So if you have the spare cash, are interrested in saving money on future electricity bills, care for the environment, and would like to be less dependent on fossil fuels, why not take a deeper look into the world of renewable energy resources.
