Solar energy seemed rather far fetched for use in homes just a few decades ago but recently the possibility of supplying a house with all or most of its energy needs using solar power has become an expectation rather than a luxury. Solar panel technology has become so affordable and incentivized by the UK government that more people than ever are considering investing in solar power as the renewable energy solution of choice.
Photovoltaics is the method of direct conversion of light to electricity. Some substances manifest a property called the photoelectric effect which causes them to absorb photons and release electrons which can be captured to produce an electric current. This is the principal behind solar energy where a surface with this property is exposed to the sun to absorb photons from natural light available to generate electricity. This need not be confined to laboratories and may even be used to generate electricity for your own home.
Solar energy is created by capturing light from the sun and with it, producing usable energy for homes and businesses. Solar energy is considered as the cleanest kind of sustainable energy sources available and can help to reduce the effects of overusing harmful fossil fuels for energy provision. The photovoltaic effect is responsible for the process of turning radiation from the sun into electricity and is an effect displayed by various kinds of semiconductors including mono and poly-crystalline silicon.
Solar energy can be defined as the generation of electricity using energy from the sun as the source. The generation of electricity using energy from the sun is achieved by utilizing the photovoltaic effect. The photovoltaic effect is a reaction to sunlight exhibited by semiconductors such as cadmium telluride crystalline silicon.
Looking for sustainable sources of energy generation has become a popular task for environmental organizations and governments through out the world as it has been widely suggested that fossil fuels are due to run out shortly if current rates of energy usage remains. The current rate of burning of fossil fuels for energy, not only contributes to its depletion, but is also blamed for contributing to the production of harmful greenhouse gases that are said to build up around the world contributing to global warming.
The principles of generating solar power rest on the photovoltaic effect exhibited by the semiconductors used to build photovoltaic modules. The photovoltaic effect occurs when photons from the sun are absorbed by semiconductors such as cadmium telluride or crystalline silicon. They respond by producing electrons in DC voltage and are used to build photovoltaic modules which can pass this DC voltage through inverters which convert them in to AC voltage. Photovoltaic module prices depend on their size, application and power load requirements.
Solar photovoltaic panels are also referred to as solar PV panels, photovoltaic panels or simply solar panels. The term 'photovoltaic' refers to the electrical effect displayed by the semiconductors used to construct solar panels. The photovoltaic effect occurs when photons from the sun are absorbed by semiconductors such as cadmium telluride and mono-crystalline silicon. These semiconductors react by emitting electrons that can be used to supply DC current. This current must be converted to AC if solar panels are to be used to supply solar energy in your home.
Renewable energy and energy efficiency are high on the agenda with today's rising fossil fuel prices. Aside from the feel-good factor of knowing that one's efforts are saving the planet, what are the benefits of getting solar energy up and running?
Solar energy has been with us for over 55 years and over that time, the materials used to produce it have greatly changed. Recently the solar energy materials and solar cells available to build a solar power generation system have developed at an accelerated rate. Consequently, staying fully informed about developments in the solar power market is more difficult than it used to be.
Why Are There So Many New Solar Energy Materials and Solar Cells?
Solar electricity payback is the money that you save from installing a solar powered hot water or heating system.
You do not experience payback until the money you have saved on your electric bills has accumulated to exceed the amount that you paid to have your solar power system installed.
A Solar Energy Calculator is a means of estimating how much energy can be generated from a Solar Energy driven Power System. The reasons for needing to know this vary from just needing to know how big the system needs to be to supply the demand it has been installed to meet, to generating extra electricity for sale to the National Grid via a Solar Feed in Tariff, (which is essentially the rate paid for the electricity supplied to the Grid.)
The modern world of technology has finally managed to embrace a solution to the ever increasing over-use of fossil fuels to generate power. Using fossil fuels is not only a dirty form of electricity production churning masses of greenhouse gases into the atmosphere, it is also unsustainable.
Solar electricity is generated through a system such as solar panels which absorb energy from the rays of the sun and convert them into electricity which can be used to power the home or a business. Solar power can be generated without direct sunlight meaning that all hours of daylight can convert the sun's energy into electricity.
Benefits of using Solar Electricity
Solar electricity or solar power is considered to be a green energy source and so has a direct positive effect on the environment.
Solar energy heating systems are considered to be the most popular form of environmentally friendly heating, praised for the lack of contribution towards the globes green house effect. Although not able to heat a homes entire water supply, the systems are said to work effectively to heat at least a 3rd of the water needed in a residential building.
The term Solar basically means \'of the Sun\' so Solar energy is energy that comes from the Sun. Our Sun provides the Earth with a huge amount of power, in the form of Solar Radiation, every day. Mankind has attempted to harness the power of the Sun for centuries in many ways but only over the last 100 years have technologies improved to a point where Solar Energy can be actively stored and converted to suit whatever need Man has. This is what is now known as Active Solar Energy. The following are a few examples of the main ways that Active Solar Energy is obtained.
