Solar Energy is simply energy given by the sun. This was originally discovered by the early Greeks, Native Americans and Chinese somewhere in 1954, when they used the heat and light given by the sun to help warm there homes, buildings and produce a form of light so they can see. (http://en.wikipedia.org/wiki/Solar_energy)
Looking back in time candles was the first source of light used. This is when Humphrey Davy discovered light bulbs (http://www.inventionexpose.com/Light+Bulb+Invention.1110.htm), but as technology continued to grow we was able to introduce solar energy lights simply because electrical lights cost too much money.

Solar powered technology works when light is exposed to a product. The disadvantage of this method is that a certain amount of power is needed for solar powered technology to work. An example of a solar powered technology is a solar powered calculator. If there is not enough solar power for the calculator it will not work. A solar powered calculator requires 100watts of solar power, if there is 90watts of solar power it can not work. However the advantage of this is that once the user has finished using the calculator then the power stores itself to be used again.

Calculators are not the only type of technology that uses Solar Power there is also:

• Solar powered lights
• Electricity
• Solar powered cars.

Here are a few things that use Solar Power. But how useful is solar energy? Can the sun give out so much energy to run almost every sort of technology from things like Cars, Computers to Mobile Phones?
Most importantly when using solar energy what is being affected by it? Does it increase global warming in anyway?

Solar powered lights outside in a garden works very well because during the day when the sun is out the battery of the solar powered lights is charged by the sun’s energy. So when it is dark at night time the lights battery will be fully charged without any extra cost to the user.
Within the next five to ten years will there be any improvement on solar energy lights? I believe that there will be no improvement on solar energy lights, the reason for this is because it is a natural resource, we can not control when the sun comes out to charge the lights. Even though the sun is a natural resource, we have to ask ourselves is there anyway we can improve on solar powered lights?

What do we believe is better?

I have gone round asking for people’s opinions on what is better out of electrical light and solar powered lights. One person said that there is no difference in terms of power because it gives of the same amount of power as each other once the solar energy lights is fully charged. But the same person also said the advantage of electrical lights is that continuous power is given to the light, which means that the light will remain bright. The only difference between them is the financial side. Electrical lights will cost more but more effective. As for solar power, it is unlimited and priceless but less effective to the user. So how can we improve on solar powered lights?

For every hour that a 100watts light is on electrically, it cost us approximately one pound, so within twenty four hours of our light being on, it cost us twenty four pounds which as students we can not afford. As for solar powered lights, it cost thirty pounds which will definitely benefit us as students because it almost cost thirty pounds just for a light to be on for twenty four hours. This will save any student anyway a fortune.

The same thing applies for solar powered cars, the car is charged from the suns solar energy which means that the car has unlimited power as long as the sun is out. But how could technology improve on a natural resource like the sun? We have been able to increase technology from candles to electrical light and from electrical to solar energy lights. So is it even possible to increase technology even more?

There is nothing but advantages to the users of solar energy lights:

• Power is unlimited.
• Charged power can be stored and used for another occasion.
• Cheaper on price.

This is a short list on why having solar energy lights is an advantage. Looking at it in the long run, a lot of technology will be relying on natural resource power. One of this will be the sun.

Conclusion

How effective is Solar Power Technology?

As I have just explained within my article solar energy is an unlimited source of energy that helps with multiple amounts of things like lights, cars, electricity and many more, which leads to my conclusion that solar energy is amazingly useful, so useful that no amount of research can express how important solar power technology. This article is a small part to solar technology.
