Solar Energy - An Historical Perspective

in Solar-panel

Solar energy has been in existence quite literally for the entire history of planet earth. Solar energy describes the energy emitted from the sun, quite a lot of which reaches earth in the form of light and also heat. This article discusses how solar energy has been utilized in the past and takes a look at the many ways it's utilised in modern times.

The history of solar energy as well as the development of solar panels

All through history humanity as well as all kinds of flora and fauna have taken advantage of solar energy. Light and heat energy generated by the sun has been used to heat water, dry out fur or clothing and to help plants for instance grow. Romans and Greeks alike used the sun's rays for all types of innovations for instance heating structures and baths! The fantastic thing about solar energy was that and indeed is reliable: it will constantly be there and will never run out for the conceivable future of humankind.

The restrictions historical past has had to deal with however is the fact that although solar energy may perform certain things, it could never be focused enough to do anything at all more useful. However, with the advent of the first solar power panels it was suddenly possible to make use of solar energy to generate electricity, making solar electrical energy infinitely more practical! Through making use of photovoltaic cells light energy can be changed into electric power. Whilst the first solar panels weren't very efficient, today's current solar panels power homes, businesses and towns! In fact its installations have become the most desirable kind of sustainable energy production across the UK and indeed the entire world. With solar panel installations now costing an average sized property close to £10,000, a solar panel installation has become an accessible sort of energy generation for many people. Especially when one considers the economic advantages which can also be gained in many European counties. In the UK for instance as the system presently stands a typical sized residence can easily gain over £1000 in economic benefits annually! When one factors this into the reasons why the ancients loved solar energy i.e. its reliability, you can certainly understand why solar panels have grown to be such an exciting and popular technology.

How solar panels are used today

Many European countries are increasingly making use of solar panels to fulfill their energy needs. In many instances panels are being used to produce electricity to feed straight into domestic or industrial circuits. Once in the system when you make use of your Television set or washing machine in the day time you're going to be making use of the electrical power which your panels created. A more simplistic approach is that taken by many households in Greece, who use solar panels principally for heating up water. An additional use across Europe of a kind that is becoming increasingly popular is using solar panels to power road signs. If you look very carefully in the UK and France for instance many road signs which illuminate or show information have panels connected up to them which are often visible. This dramatically cuts down on energy bills, particularly when one considers the number of electronic road signs there are across Europe!

At the moment panels can simply change light energy into electrical power, but do not yet have the capability to store energy and release it when needed. As it stands if you have a solar panel installation you will be using solar electricity during the day but not during the night. The next move as well as the future for panels then will be a system through which light energy is changed into electricity and kept so you will always be making use of free electrical power if you have a panel installation!
